The Bitcoin Gold algorithm was originally created by Zcash, now renamed as the Electric Coin Company, but the Bitcoin Gold creators remodelled the algorithm and is now called Equihash BTG.Crypto version of fiat which is tied to the value of resources like gold or the U.S.CHECKLOCKTIME fields.Locktime fields in Bitcoin can contain either a block height or a Unix epoch time value.If the example webserver were compromised and the external addresses were leaked, the attacker would learn about each time the user received money, how much they received, and when they initially spent the money-but they wouldn’t necessarily learn how much money was sent in the initial spend, and they also might not learn about any spends that entirely consisted of spending change.Enabling CSFS-like behavior on Bitcoin would allow the creation of covenants and other advanced contracts without having to presign spending transactions, possibly reducing complexity and the amount of data that needs to be stored.It adds for invoice metadata which can be used by other programs (and potentially future versions of LND) for stateless invoices and adds support to the internal wallet for receiving and spending bitcoins to P2TR keyspend outputs, along with experimental MuSig2 support.
With few negative reports and significant potential fee savings for those wallets and services that support receiving to bech32 addresses, it may be time for more wallets to begin making bech32 their default address format.Bitcoin Core doesn’t support signing or verifying arbitrary messages for any other address type, including addresses covering single-sig P2SH-P2WPKH, native P2WPKH, and P2TR outputs.RETURN or scripts larger than the max script size are removed from the UTXO set, removing uneconomical outputs could cause issues, including a hard fork as Pieter Wuille points out, if those outputs are spent.● Does an uneconomical output need to be kept in the UTXO set? This week, Ali Sherief proposed that the same message signing algorithm used for P2WPKH also be used for other output types.A previous proposal, BIP322, to provide fully generic message signing that could work with any script has not yet been merged into Bitcoin Core or added to any other popular wallet of which we’re aware.
Consider mining software a way for miners to work.While this waste heat can be a problem at other times, those in colder climates can harness this heat in a way that heats their home – while mining crypto at the same time! She reports that the main concept discussed was attempting to bound the maximum amount of resources used for relaying transactions and their replacements, such as by limiting the number of related transactions that get relayed within a certain amount of time.For example, a transaction could suggest limiting the maximum amount of space it and its descendants could consume in the mempool [click here to find out more](https://m.blog.naver.com/ajjuguru/223218497656) 1,000 vbytes instead of the default 100,000 vbytes.This week, developer w0xlt posted to the Bitcoin-Dev mailing list a tutorial for creating silent payments for the default signet using a proof-of-concept implementation for Bitcoin Core.
1001 recommends that nodes who advertise a change to their payment forwarding policies continue accepting payments received using the old policies for about 10 minutes.This week’s newsletter describes experimentation by developers working on silent payments and includes our regular sections with summaries of new releases and release candidates plus notable changes to popular Bitcoin infrastructure software.This week’s newsletter describes a proposed BIP for creating signed messages for non-legacy addresses and summarizes a discussion about provably burning small amounts of bitcoin for denial of service protection.This week’s newsletter includes our regular sections summarizing popular questions and answers from Bitcoin Stack Exchange, announcing new software releases and release candidates, and describing recent changes to Bitcoin infrastructure software.Also included are our regular sections with popular questions and answers from the Bitcoin Stack Exchange, announcements of new releases and releases candidates, and summaries of notable changes to popular Bitcoin infrastructure software.
CHECKTEMPLATEVERIFY (CTV) opcode have continued with summaries provided by Jeremy Rubin: 1, 2, 3, 4, and 5.Additionally this past week, James O’Beirne posted code and design documentation for a CTV-based vault.FOLD opcode as a way to allow loop-like behavior in Bitcoin Script.
CHECKTEMPLATEVERIFY opcode.Also included is our regular section describing notable changes to popular Bitcoin infrastructure projects.1088 adds the structures needed for compact blocks as specified in BIP152, as well as a method for creating a compact block from a regular block.Compact blocks allow a node to tell its peers which transactions a block contains without sending complete copies of those transactions.
Peers are authorized using runes, which is a custom CLN protocol based on a simplified version of macaroons.The updated protocol is designed to maximize efficiency, especially when combined with an erlay-like minisketch-based efficient gossip protocol..
