EXTONS.IO EXCHANGE PLATFORM - AN EVOLUTION IN CRYPTOCURRENCY AND DIGITAL ASSETS TRADING WITH FIAT.
https://ibb.co/BGD1YnW The need for cryptocurrency exchange platforms started arising from the time when cryptocurrencies were created, because they are a crucial part of the cryptocurrency industry, since most of the crypto-related operations take place on it. An exchange is a platform, either decentralized or centralized, where users of cryptocurrencies and other digital assets, can readily exchange or even trade their assets to fiat currency or other digital assets of choice. These exchange platforms are developed using improved technologies like the Blockchain, so as to help it efficiently manage the complex trading activities of users, and aid these users in maximizing profits. Since the number of cryptocurrencies in the digital assets market has been growing uncontrollably, these cryptocurrency exchange platforms need to be present to meet the demands of users. EXTONS.IO EXCHANGE WAS CREATED EXTONS.IO exchange is a cryptocurrency exchange platform built by the Thisoption ecosystem, to help make the trade in cryptocurrency seamless. EXTONS as a cryptocurrency exchange is a product part of Thisoption Limited's ecosystem and is available as a trading engine for cryptocurrency and other digital assets trading. EXTONS.IO was made to be a centralized exchange type and as such, make cryptocurrency trading effortless, easy and smooth. The Extons platform has several benefits that makes it beffiting of a modern day trading platform. In order to perform with full force, the EXTONS.IO exchange system will also make use of the Blockchain technology and its smart contract, in executing transactions and other operations. The Blockchain will be helpful in a lot of ways, just to make the EXTONS.IO exchange, the best of its kind, as it helps guarantee security of every transaction and data on the system. Whenever user data is generated, the system stores it on its unalterable Blockchain technology, which is as well viewable for the users. This means that transactions on the EXTONS.IO exchange will be transparent as they can be monitored and its details seen on the Blockchain, at any time. These is just a tip of the iceberg, when it comes to the benefits of using the EXTONS.IO exchange over others. EXTONS.IO EXCHANGE BENEFITS There is always high liquidity as one of the advantages of trading on the EXTONS.IO exchange, as it is always endowed with a great amount of liquidity, providing a fully functioning system for users to trade efficiently.

So after having spoken to the guys and sold on the domain for a very generous price, there is a brand new Flixify service that has just started and sign up is open, however please bare in mind the following before you head there! PLEASE PAY SPECIAL ATTENTION TO THIS:- The new service is by a few members of the old Flixify team that have branched off due to arguments and moral disagreements. The new service can only be signed up for if a Registration and Subscription key is purchased and this can only be paid for in Bitcoin (BTC) through their Shoppy store and NO there isn't a Debit/Credit card option and won't be because the new team cannot obtain payment processor services such as PayPal/Stripe/Payoneer etc... The price is approx 0.014 BTC which is roughly $125 USD or £100 GBP and includes your key for sign up and a 6 month full access subscription with no limits on devices / logins and Downloads are enabled. There is NO trial available and there is NO invite system in place and won't be for quite some time. User limit is 100 users right now and they've asked that people do not click to purchase if they're not serious and cannot pay in Bitcoin. As long as it is understood that the Reg/Sub key has to be purchased first and paid for in Bitcoin then head to https://flixify.online/signup.php and go in there before they all go!
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications. Ubuntu http://groestlcoin.org/forum/index.php?topic=441.0
ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )

Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
Lastupdated2018-01-29 This post is a collaboration with the Bitcoin community to create a one-stop source for Lightning Network information. There are still questions in the FAQ that are unanswered, if you know the answer and can provide a source please do so!
Lightning Network White Paper - The protocol has changed since this original paper, but covers the mid-level mechanics of the Lightning Network with an emphasis on the smart contracts that make it trustless
If you can answer please PM me and include source if possible. Feel free to help keep these answers up to date and as brief but correct as possible
Is Lightning Bitcoin?
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Is the Lightning Network open source?
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Who owns and controls the Lightning Network?
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
I’ve heard that Lightning transactions are happening “off-chain”…Does that mean that my bitcoin will be removed from the blockchain?
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Do I need a constant connection to run a lightning node?
Not necessarily, Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
What Are Lightning’s Advantages?
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Does Lightning require Segregated Witness?
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
Can I Send Funds From Lightning to a Normal Bitcoin Address?
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Can I Make Money Running a Lightning Node?
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
What is the release date for Lightning on Mainnet?
Would there be any KYC/AML issues with certain nodes?
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
What is the delay time for the recipient of a transaction receiving confirmation?
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source
How does the lightning network prevent centralization?
How would the lightning network work between exchanges?
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
How do lightning nodes find other lightning nodes?
Does every user need to store the state of the complete Lightning Network?
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
Would I need to download the complete state every time I open the App and make a payment?
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
What needs to happen for the Lightning Network to be deployed and what can I do as a user to help?
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above. All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Is there anyway for someone who isn't a developer to meaningfully contribute?
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
Do I need to be a miner to be a Lightning Network node?
Do I need to run a full Bitcoin node to run a lightning node?
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
How does the lightning network stop "Cheating" (Someone broadcasting an old transaction)?
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-) For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
How many times would someone need to open and close their lightning channels?
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user. Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
Will the lightning network reduce BTC Liquidity due to "locking-up" funds in channels?
When setting up a Lightning Network Node are fees set for the entire node, or each channel when opened?
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Can Lightning routing fees be changed dynamically, without closing channels?
Yes but it has to be implemented in the Lightning software being used. -- Source
How can you make sure that there will be routes with large enough balances to handle transactions?
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
How does the Lightning Network stop flooding nodes (DDoS) with micro transactions? Is this even an issue?
Hal Finney, while paralyzed by ALS, wrote code for a bitcoin wallet using only his eyes
It's important to remember Bitcoin's roots, and the amazing effort from brilliant people, like Hal, who contributed to this new technology. If you're feeling down, this is an absolute must read. I have it saved, and read it every once in awhile, enjoy.
"And of course the price gyrations of bitcoins are entertaining to me. I have skin in the game. But I came by my bitcoins through luck, with little credit to me. I lived through the crash of 2011. So I've seen it before. Easy come, easy go." - Hal Finney, March 19, 2013, 08:40:02 PM
Bitcoin and me (Hal Finney) Copied from https://bitcointalk.org/index.php?topic=155054.0 I thought I'd write about the last four years, an eventful time for Bitcoin and me. For those who don't know me, I'm Hal Finney. I got my start in crypto working on an early version of PGP, working closely with Phil Zimmermann. When Phil decided to start PGP Corporation, I was one of the first hires. I would work on PGP until my retirement. At the same time, I got involved with the Cypherpunks. I ran the first cryptographically based anonymous remailer, among other activities. Fast forward to late 2008 and the announcement of Bitcoin. I've noticed that cryptographic graybeards (I was in my mid 50's) tend to get cynical. I was more idealistic; I have always loved crypto, the mystery and the paradox of it. When Satoshi announced Bitcoin on the cryptography mailing list, he got a skeptical reception at best. Cryptographers have seen too many grand schemes by clueless noobs. They tend to have a knee jerk reaction. I was more positive. I had long been interested in cryptographic payment schemes. Plus I was lucky enough to meet and extensively correspond with both Wei Dai and Nick Szabo, generally acknowledged to have created ideas that would be realized with Bitcoin. I had made an attempt to create my own proof of work based currency, called RPOW. So I found Bitcoin facinating. When Satoshi announced the first release of the software, I grabbed it right away. I think I was the first person besides Satoshi to run bitcoin. I mined block 70-something, and I was the recipient of the first bitcoin transaction, when Satoshi sent ten coins to me as a test. I carried on an email conversation with Satoshi over the next few days, mostly me reporting bugs and him fixing them. Today, Satoshi's true identity has become a mystery. But at the time, I thought I was dealing with a young man of Japanese ancestry who was very smart and sincere. I've had the good fortune to know many brilliant people over the course of my life, so I recognize the signs. After a few days, bitcoin was running pretty stably, so I left it running. Those were the days when difficulty was 1, and you could find blocks with a CPU, not even a GPU. I mined several blocks over the next days. But I turned it off because it made my computer run hot, and the fan noise bothered me. In retrospect, I wish I had kept it up longer, but on the other hand I was extraordinarily lucky to be there at the beginning. It's one of those glass half full half empty things. The next I heard of Bitcoin was late 2010, when I was surprised to find that it was not only still going, bitcoins actually had monetary value. I dusted off my old wallet, and was relieved to discover that my bitcoins were still there. As the price climbed up to real money, I transferred the coins into an offline wallet, where hopefully they'll be worth something to my heirs. Speaking of heirs, I got a surprise in 2009, when I was suddenly diagnosed with a fatal disease. I was in the best shape of my life at the start of that year, I'd lost a lot of weight and taken up distance running. I'd run several half marathons, and I was starting to train for a full marathon. I worked my way up to 20+ mile runs, and I thought I was all set. That's when everything went wrong. My body began to fail. I slurred my speech, lost strength in my hands, and my legs were slow to recover. In August, 2009, I was given the diagnosis of ALS, also called Lou Gehrig's disease, after the famous baseball player who got it. ALS is a disease that kills moter neurons, which carry signals from the brain to the muscles. It causes first weakness, then gradually increasing paralysis. It is usually fatal in 2 to 5 years. My symptoms were mild at first and I continued to work, but fatigue and voice problems forced me to retire in early 2011. Since then the disease has continued its inexorable progression. Today, I am essentially paralyzed. I am fed through a tube, and my breathing is assisted through another tube. I operate the computer using a commercial eyetracker system. It also has a speech synthesizer, so this is my voice now. I spend all day in my power wheelchair. I worked up an interface using an arduino so that I can adjust my wheelchair's position using my eyes. It has been an adjustment, but my life is not too bad. I can still read, listen to music, and watch TV and movies. I recently discovered that I can even write code. It's very slow, probably 50 times slower than I was before. But I still love programming and it gives me goals. Currently I'm working on something Mike Hearn suggested, using the security features of modern processors, designed to support "Trusted Computing", to harden Bitcoin wallets. It's almost ready to release. I just have to do the documentation. And of course the price gyrations of bitcoins are entertaining to me. I have skin in the game. But I came by my bitcoins through luck, with little credit to me. I lived through the crash of 2011. So I've seen it before. Easy come, easy go. That's my story. I'm pretty lucky overall. Even with the ALS, my life is very satisfying. But my life expectancy is limited. Those discussions about inheriting your bitcoins are of more than academic interest. My bitcoins are stored in our safe deposit box, and my son and daughter are tech savvy. I think they're safe enough. I'm comfortable with my legacy. [edited slightly] - Hal Finney
Could porn pave the way for cryptocurrency adoption by merchants?
Hey guys, I’ve been a webmaster since I graduated college (Clemson, go Tigers!) in 2003. Some of my portfolio includes adult webcam projects. I could use your help with an upvote on this topic if you wouldn’t mind. My goal is to show the adult webmasters the massive size of the crypto community. We just implemented new cryptos on our platform and I want to urge other webmasters to do the same. Once this gets some legs, I plan on posting it to some adult webmaster news resources such as XBiz and AVN. It would be huge if we got this on the first page of Reddit to show them the demand. I’m not sure if you’re up on your internet history, but if you watched the movie Middle Men, you would know that Porn paved the way for online billing back in the late 90s. So maybe, just maybe, this could be substantial for merchant adoption. Without further ado, here’s the letter I plan on publishing… Dear Fellow Adult Webmasters, Rather than submit a press release about adding multiple cryptocurrencies to our payment options on camwithher.com, I wanted to reach out to my fellow webmasters and urge you to do the same. The adult industry paved the way for online credit card processing in the late 1990s. Perhaps it can also pave the way for cryptocurrency payments online. We were the first cam site (and perhaps adult site in general?) to offer Bitcoin deposits (https://bitcointalk.org/index.php?topic=138248.0) in January of 2013. Then unknown cryptocurrency advocates (now major influencers), Erik Voorhees (Shapeshift.io) and Tony Gallippi (Bitpay.com), convinced me to integrate Bitcoin into one of our more unkown cam sites as a test. At first, I was skeptical of digital money, transferring it 100% into fiat, however, I quickly changed my tune. Soon thereafter I integrated Bitcoin into our other sites and adjusted our settlement from 100% fiat to 100% Bitcoin. I got a fever, and the only prescription was more crypto. I was hooked. I started becoming a huge crypto advocate myself. I spoke at Bitpay’s Internext seminar. I went on to build my first mining rig. I invested in alt coins. It became a whole “thing”. HODLing became life. Fast forward to today, cryptocurrency has come a long way, getting integrated more and more into everyday life and featured in major news headlines. However, there’s still a long road ahead in mass adoption, and this is where I think we can significantly make an impact. A vast majority of merchants don’t accept cryptocurrency and there’s absolutely no reason not to. Let me explain… Do you like low merchant fees? Well you’re not going to get any lower than .5%. What other processor (especially in adult) will give you that? CoinPayments.net will and they’ll throw in a Paypal option at no charge. Some adult processors are taking 15% or higher. Do you like getting chargebacks? Of course you don’t, and you won’t have to with cryptocurrency. There are no chargebacks. Yeah, none, zip, zilch, nyet, you get the picture. Not a huge fan of crypto? No problem, get everything settled in fiat at no charge. If you’re anything like me, that will change. What’s in it for me you ask? Sure, I own crypto and it would be nice to see it go up in value, but that isn’t why I’m writing this. Sure, my cam site is featured in this letter so you may be thinking I want the traffic. Traffic is nice, don’t get me wrong, but I sincerely want to see crypto get to the next level. I believe in the vision and want to see it succeed. You have nothing to lose! So you only have to ask yourself one question. When Lambo? You’ll understand that once you dive in ;) All the best, Steve President SNR Productions, Inc. Disclaimer: I kept most links out of this letter that I plan on putting in the news articles. I just wanted to follow the rules of this sub and didn't want this to appear as spam, so I left them out. PS. I'm extremely excited to be the first cam site to offer BTC, LTC, BCH, DASH, DOGE, ETC, ETH, LSK, NEO, QTUM, STEEM, XMR, ZEC, and XRP payments! edit: Wow ranked #3 on cryptocurrency! Thanks everyone! This is going to def turn some heads.
These email addresses were used on domain registrations, forums, payment processors, and a variety of services linking back to Gerald Cotten (more on this later)
Given the preponderance of inexpensive, cheap and more powerful options for name servers (such as Cloudflare, which was used by QuadrigaCX), and Cotten’s preoccupation with security, using proxy services and hiding his IP we can assume this would have been primarily for security reasons
Cotten used the “contentbysceptre.com” domain in connection with his “Sceptre’s Spectacular Content Services” on BlackHatWorld
Cotten posted an advertisement on Blackhatworld for a programmer for a “Website like Bitstamp”, which was just a few months prior to launching QuadrigaCX in December 2013. It’s a short timeframe but we know it fits because QuadrigaCX uses the generic WLOX exchange script, which dramatically reduces the work required to build a crypto exchange (Note: we didn’t say a great crypto exchange). This is mentioned in a post on coinforum.ca where user @yerofeyev admits that another exchange, Taurs (founded with PATRYN, mentioned earlier) uses Quadriga code based on WLOX. Strangely that thread is no longer accessible (https://coinforum.ca/discussion/2448/taurs-soft-launch) as the whole coinforum.ca website has been mysteriously shut down in the last few days
Cotten posted a number of threads asking for advice on how to monetise his network of sites, includijg the aforementioned proxy sites, and his celebrity news sites, including celebritydaily.net. Here’s the link to that post as well “BHW - Hiring Celebrity Article Writer”
Cotten’s profile on BlackHatWorld was initially Sceptre and later changed to “Murodch1337” , perhaps after QuadrigaCX began to become popular and he realised he might need to conceal links to his past. Link to Cottens BlackHatWorld profile here: https://www.blackhatworld.com/members/murdoch1337.273596/
We know form other research and analysis that both Sceptre and Patryn were highly active in the HYIP/Ponzi/exchanger space (more on this later)
In conclusion, we believe that Gerald Cotten, QuadrigaCX CEO, was known as "Sceptre" on BlackHatWorld and other sites.
This has been a QCXINT release.

The two companies plan to provide customers with the ability to book flights while paying with cryptocurrencies such as Bitcoin (BTC), Ethereum (ETH), Dash, DigiByte (DGB) and Utrust’s native token UTK. IRS Clarifies Its Confusing ‘Airdrop’ Cryptocurrency Tax PolicyAmerica’s top tax authority, the Internal Revenue Service (IRS), has somewhat provided clarification about its recent cryptocurrency tax guidelines. However, their final decision regarding taxing promotional airdrops is yet to be made.Critics pointed out a range of potential problems with the latest guidelines, issued in October. Perhaps most glaring among these issues was a section about “airdrops” — which, in the world of cryptocurrencies, is usually used to refer to promotional giveaways or customer rewards.Per Bloomberg Tax, Christopher Wrobel, an attorney in the IRS Office of the Associate Chief Counsel (Income Tax and Accounting) confirmed that while hard fork-generated revenues are taxable under the latest rulings, the revenue ruling doesn’t apply to promotional airdrop giveaways. But Wrobel did state that the IRS “hasn’t yet decided” whether such promotional airdrops should be treated as taxable. AFME Calls For Supervisory Convergence On The Regulation Of Crypto-AssetsThe Association for Financial Markets in Europe (AFME) has published a new paper outlining five recommendations for delivering “supervisory convergence on the regulation of crypto-assets” across the region.In other words, the voice of Europe’s wholesale financial markets is saying it wants to encourage collaboration between regulators and those in Europe willing to tap into the cryptocurrency world by drawing up pointers which “work towards a common approach to the regulation and development of crypto-assets in financial services.” https://preview.redd.it/h5dqt7q85ny31.png?width=504&format=png&auto=webp&s=3975c5edb5c26fd3fdc100264cb5b9c3e4337516 Yesterday, we saw a couple of bearish patterns for bitcoin below the $8,880 resistance against the US Dollar. BTC remained in a bearish zone below the $8,800 level and the 100 hourly simple moving average. The last rejection was near the $8,780 level and the 100 hourly SMA. A high was formed near $8,784 before the price declined below $8,700. Moreover, the price traded below $8,680 and it is currently testing the $8,640 support area. If there is an upside correction, the $8,710 level is an immediate resistance. Besides, the 50% Fib retracement level of the recent decline from the $8,784 high to $8,636 low is also near the $8,710 level. Review previous articles:https://email@example.com

A lot of people on Reddit think of Bitcoin primarily as a competitor to card payment networks. I think this is more than a little odd-- Bitcoin is a digital currency. Visa and the US dollar are not usually considered competitors, Mastercard and gold coins are not usually considered competitors. Bitcoin isn't a front end for something that provides credit, etc. Never the less, some are mostly interested in Bitcoin for payments (not a new phenomenon)-- and are not so concerned about what are, in my view, Bitcoin's primary distinguishing values-- monetary sovereignty, censorship resistance, trust cost minimization, international accessibility/borderless operation, etc. (Or other areas we need to improve, like personal and commercial privacy) Instead some are very concerned about Bitcoin's competitive properties compared to legacy payment networks. ... And although consumer payments are only one small part of whole global space of money, ... money gains value from network effects, and so I would want all the "payments only" fans to love Bitcoin too, even if I didn't care about payments. But what does it mean to be seriously competitive in that space? The existing payments solutions have huge deployed infrastructure and merchant adoption-- lets ignore that. What about capacity? Combined the major card networks are now doing something on the other of 5000 transactions per second on a year round average; and likely something on the order of 120,000 transactions per second on peak days. The decentralized Bitcoin blockchain is globally shared broadcast medium-- probably the most insanely inefficient mode of communication ever devised by man. Yet, considering that, it has some impressive capacity. But relative to highly efficient non-decentralized networks, not so much. The issue is that in the basic Bitcoin system every node takes on the whole load of the system, that is how it achieves its monetary sovereignty, censorship resistance, trust cost minimization, etc. Adding nodes increases costs, but not capacity. Even the most reckless hopeful blocksize growth numbers don't come anywhere close to matching those TPS figures. And even if they did, card processing rates are rapidly increasing, especially as the developing world is brought into them-- a few more years of growth would have their traffic levels vastly beyond the Bitcoin figures again. No amount of spin, inaccurately comparing a global broadcast consensus system to loading a webpage changes any of this. So-- Does that mean that Bitcoin can't be a big winner as a payments technology? No. But to reach the kind of capacity required to serve the payments needs of the world we must work more intelligently. From its very beginning Bitcoin was design to incorporate layers in secure ways through its smart contracting capability (What, do you think that was just put there so people could wax-philosophic about meaningless "DAOs"?). In effect we will use the Bitcoin system as a highly accessible and perfectly trustworthy robotic judge and conduct most of our business outside of the court room-- but transact in such a way that if something goes wrong we have all the evidence and established agreements so we can be confident that the robotic court will make it right. (Geek sidebar: If this seems impossible, go read this old post on transaction cut-through) This is possible precisely because of the core properties of Bitcoin. A censorable or reversible base system is not very suitable to build powerful upper layer transaction processing on top of... and if the underlying asset isn't sound, there is little point in transacting with it at all. The science around Bitcoin is new and we don't know exactly where the breaking points are-- I hope we never discover them for sure-- we do know that at the current load levels the decentralization of the system has not improved as the users base has grown (and appear to have reduced substantially: even businesses are largely relying on third party processing for all their transactions; something we didn't expect early on). There are many ways of layering Bitcoin, with varying levels of security, ease of implementation, capacity, etc. Ranging from the strongest-- bidirectional payment channels (often discussed as the 'lightning' system), which provide nearly equal security and anti-censorship while also adding instantaneous payments and improved privacy-- to the simplest, using centralized payment processors, which I believe are (in spite of my reflexive distaste for all things centralized) a perfectly reasonable thing to do for low value transactions, and can be highly cost efficient. Many of these approaches are competing with each other, and from that we gain a vibrant ecosystem with the strongest features. Growing by layers is the gold standard for technological innovation. It's how we build our understanding of mathematics and the physical sciences, it's how we build our communications protocols and networks... Not to mention payment networks. Thus far a multi-staged approach has been an integral part of the design of rockets which have, from time to time, brought mankind to the moon. Bitcoin does many unprecedented things, but this doesn't release it from physical reality or from the existence of engineering trade-offs. It is not acceptable, in the mad dash to fulfill a particular application set, to turn our backs on the fundamentals that make the Bitcoin currency valuable to begin with-- especially not when established forms in engineering already tell us the path to have our cake and eat it too-- harmoniously satisfying all the demands. Before and beyond the layers, there are other things being done to improve capacity-- e.g. Bitcoin Core's capacity plan from December (see also: the FAQ) proposes some new improvements and inventions to nearly double the system's capacity while offsetting many of the costs and risks, in a fully backwards compatible way. ... but, at least for those who are focused on payments, no amount of simple changes really makes a difference; not in the way layered engineering does.
