<br> Several recent releases of Bitcoin Core might be re-released with slightly different version numbers so that their Windows binaries can use this certificate. The more outputs that are spent together, the higher the fee might be for that particular transaction relative to a wallet with default flags but, also, the less likely it becomes that third parties will be able to identify the user’s later transactions. If you’re in a situation where you have been scammed, you might want to contact a lawyer. One commentator points out that the use of BIP69 has so far caused three separate problems that may have led to accidental channel closures and small amounts of funds lost to unnecessary onchain fees. 872 updates BOLT3’s use of BIP69 to specify in more detail the sort order to use for commitment transaction inputs and outputs. In order to verify the transaction and update the ledger, one of the nodes must come up with the solution to a difficult mathematical problem called a “‘hash function,”‘ which takes the raw data from the transaction request and reduces it into a new string of data with a shorter, fixed length. Taproot support in the UI is planned for a future updat<br>p><br>p> ● LND 0.13.0-beta.rc3 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. A. Bitcoin uses public-key cryptography, peer-to-peer networking, and proof-of-work to process and verify payments. ● HWI 2.0.2 is a minor release that adds support for message signing with the BitBox02, always uses h instead of ‘ to indicated BIP32 paths with hardened derivation, and includes several bug fixes. Sometimes, this can be as simple as changing paths to prefix /usr/local as the install destination. However, Erhardt and Shikhelman note that a more sophisticated algorithm that may require a bit more CPU can find sets of related transactions that are even more profitable to mine than Bitcoin Core’s existing simple algorithm. ● 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. The higher the price of bitcoin, the more miners are competing, and the harder the puzzles get. Notable changes this week in Bitcoin Core, C-Lightning, Eclair, LND, Rust-Lightning, libsecp256k1, Hardware Wallet Interface (HWI), Rust Bitcoin, BTCPay Server, http://www.youtube.com BDK, Bitcoin Improvement Proposals (BIPs), and Lightnin<br>L<br>
4890 allows the user to configure a backup sqlite database file for the wallet. This allows Bitcoin Core to fairly compare all transactions in the mempool based on their effective feerate whether or not those transactions have any ancestors. This change allows the testmempoolaccept RPC to accept multiple transactions where later transactions may be descended from earlier transactions. By making multiple withdrawals to different addresses generated by different wallets over a long period of time, you are further improving your anonymity. 5155 adds a configuration option to randomly select which wallet UTXOs to spend in a transaction; this reduces UTXO fragmentation in the wallet over time. Bitcoin and other cryptocurrencies are kept in a cryptocurrency wallet. ● libwally-core adds bech32m support: The 0.8.4 release of this wallet primative library includes bech32m support. ● NthKey adds bech32m send capabilities: iOS signing service NthKey added support for taproot sends in the v1.<br>r<br>ase.
4501 adds JSON schemas for the output of roughly half of C-Lightning’s current commands (with schemas for the other half planned to be added in the future). ● bitcoinj adds bech32m, P2TR support: Andreas Schildbach added a commit for bech32m and another for P2TR support to the bitcoinj repository. ● Kollider launches alpha LN-based trading platform: Kollider’s latest announcement details the derivative platform’s features including LN deposits and withdrawals plus LNAUTH and LNURL support. As part of their compensation, certain CoinDesk employees, including editorial employees, may receive exposure to DCG equity in the form of stock appreciation rights, which vest over a multi-year period. That would be an improvement over the current case where each user’s CPFP fee bump is considered independently and multiple related fee bumps may not have an aggregate effect on whether an ancestor transaction is mined. This week’s newsletter describes a proposal to change Bitcoin Core’s transaction selection algorithm for miner block templates to slightly increase miner profitability and give fee bumping users more collective leverage. If implemented and used by miners, the improved algorithm could allow multiple users who each received an output from a large coinjoin or batched payment to each pay a small part of the total fee necessary to CPFP fee bump th<br>oinjoin or payment.
