21573 updates the version of libsecp256k1 included in Bitcoin Core. 22017 updates the code signing certificate used for Windows releases after the previous certificate was revoked by its issuer without them providing an explicit reason. After this change, Windows and macOS code signing remain the only missing piece before Guix builds reach feature-parity with Gitian builds. 18956 uses the API on Windows systems to require Windows 7 or later. Compared to the previous major version, it contains a several API improvements and bug fixes. ● Sparrow 1.4.0 released: Sparrow 1.4.0 adds the ability to create a child pays for parent (CPFP) transaction from the transaction list screen, user-defined fee amounts during coin selection, and various other improvements. ● LND 0.13.0-beta.rc5 is a release candidate that adds support for using a pruned Bitcoin full node, allows receiving and sending payments using Atomic MultiPath (AMP), and increases its PSBT capabilities, among other improvements and bug fixes. ● Candidate Set Based (CSB) block template construction: Mark Erhardt posted to the Bitcoin-Dev mailing list about an analysis he and Clara Shikhelman performed on an alternative transaction selection algorithm for miners. By contrast, the default coin selection algorithm in LND spends higher value UTXOs before lower value UTXOs; this minimizes fees in the short term but may result in needing to pay higher fees in the future when all inputs near the size of a transaction, or larger, have already been spent.
It would also be messy for the customer to spend from this transaction while it remains unconfirmed, as the enterprise will have to pay for this child spend when attempting to replace the parent. 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. For advanced traders, Binance offers its Futures exchange that enables leveraged trading. By contrast, if both parties use Bitcoin the payments could bypass the brokers and banks, flowing via the ICE exchange from the buyer’s to the seller’s vault held at Bakkt, and reaping big savings. According to payment industry experts, the banks might cooperate with Bakkt, because the new system could actually encourage different forms of borrowing. When combining these two tools, a service provider unlocks new functionality but is similarly exposed to novel forms of complexity.
● BlueWallet v6.1.0 released: BlueWallet’s v6.1.0 release adds Tor support, SLIP39 support, and functionality for using PSBTs with HD watch-only wallets. True for wallets that have private keys disabled (i.e. that are only useful as watch-only wallets). LN closing transactions to be able to pay any segwit script version, including script types that don’t yet have consensus meaning on the network, such as addresses for taproot. 4591 adds support for parsing bech32m addresses. After six months and over 10,000 words published, this is our last bech32 sending support section. That would be an improvement over the current case where each user’s CPFP fee bump is considered independently and 바이낸스 수수료 multiple related fee bumps may not have an aggregate effect on whether an ancestor transaction is mined. 2938 delays reprocessing of incoming HTLCs at startup until after all plugins have been loaded. 5. When all the wallets have all the nonce pairs, they combine them into a single nonce. 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.
Fees go up, fees go down, but the business must always fight for fee efficiency. ANDREESSEN: Some of that business will be transactions, some of that business will be digital contracts, some of that business will be digital keys, digital signatures and then the system will start to work itself into things like antifraud, or things like public payments, or things like micropayments. ● Electrum 4.1.0 enhances Lightning features: Electrum 4.1.0 adds trampoline payments, multipath payments, channel backups, and other Lightning features. ● C-Lightning 0.10.0 is the newest major release of this LN node software. The announcement will include a copy of the release notes detailing major changes to the software since the 0.16.0 release. In a mailing list post, bip-tapscript author Pieter Wuille notes that he and Andrew Poelstra examined other resource limits on scripts that were put in place to prevent nodes from using an excessive amount of CPU or memory during verification. The damage has been done already-adding a couple more seconds of CPU time to collect valuable information is usually a wise trade to make.
