Rusty Russell has opened a PR to the BOLT repository and started a mailing list thread for feedback on a proposal to modify the construction and signing of some of the LN transactions in order to allow both BIP125 Replace-by-Fee (RBF) fee bumping and Child-Pays-For-Parent (CPFP) fee bumping. Overall, if the proposal is implemented, it will allow users of regular single-sig transactions or uncomplicated multisignatures to join together with users of contract protocols to mutually improve each others’ privacy and fungibility. Belcher’s proposal suggests wallets randomly choose between using either nLockTime or nSequence with 50% probability when both options are available.

Towns suggests that his alternative-“Binary Tree Coded Script” or “btc-script”-would be easier to understand and use than Simplicity, although perhaps it would be harder to formally validate. The three data structures are a finite blockchain (keep N blocks into the past), an “account tree” which keeps account balance for every address with a non-zero balance, and a “proof chain” which is an (ever growing) slimmed down version of the blockchain. 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. 24304 adds a new demo bitcoin-chainstate executable that can be passed a Bitcoin Core data directory and a block, which it will validate and add to the data directory. Alternative recommendation engines can return their own scored recommendations, and the user (or their software) can decide how to aggregate or otherwise use the scores to actually decide which nodes should receive channel open attempts.

Anti fee sniping is a technique some wallets implement to discourage miners from trying to steal fees from each other in a way that would reduce the amount of proof of work expended on securing Bitcoin and limit users’ ability to rely on confirmation scores. In many ways, bitcoin works in the opposite way as traditional money: It is not controlled or issued by a central bank, it has a fixed supply (which means new bitcoins cannot be created at will) and it’s price is not predictable. The first part of our three-part Segregated Witness series covered how it works. For the first time ever, this testing can include creating a reproducible build of LND and verifying that it has the same hash as the binaries distributed by the LND developers. CHECKLOCKTIME fields. Locktime fields in Bitcoin can contain either a block height or a Unix epoch time value.

This enables the service provider to give users the experience of an instantaneous withdrawal while still retaining much of the fee savings from doing large batches of customer withdrawals at once. Been about 6 months and still no word. Over the years, Bitcoin has become more entrenched in the U.S., and its adoption is still ongoing. As of 2021, bitcoin’s annual e-waste is estimated to be over 30,000 tonnes, which is comparable to the small IT equipment waste produced by the Netherlands. However, recent activity has caused Bitcoin’s value to significantly rise at the time of this writing and has caught the attention of many existing and would-be investors. 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 Binance referral example, a transaction could suggest limiting the maximum amount of space it and its descendants could consume in the mempool to 1,000 vbytes instead of the default 100,000 vbytes.
