CAT opcode that was part of Bitcoin until mid-2010 (and which is often mentioned as a candidate for reintroduction). ● LND 0.10.1-beta.rc1 is the first release candidate for the next maintenance release of LND. ● HWI 2.0.0 is the release for the next major version of HWI. ● C-Lightning 0.10.0 is the newest major release of this LN node software. This week’s newsletter requests testing of the C-Lightning and Bitcoin Core release candidates, invites participation in structured review of the taproot proposal, highlights updates to two Bitcoin wallets, and describes a few notable changes to popular Bitcoin infrastructure projects. ● Evaluate proposed changes to BIP341 taproot transaction digest: as described in last week’s newsletter, there has been a request for taproot signatures to make an additional commitment to the scriptPubKeys of all the UTXOs being spent in a transaction. Anyone who expects to need P2SH-wrapped taproot should describe their planned use case on the mailing list or by contacting the bip-taproot author privately.
If you have any questions or concerns about the proposed transaction digest revision, we suggest either replying to the mailing list or contacting the BIP341 authors directly. Segwit eliminated third-party malleability as a concern for most transactions, but it doesn’t address the case where the creator of a transaction mutates its txid themselves, such as by fee bumping the funding transaction using Replace-by-Fee (RBF). This week’s newsletter describes a proposal for using fidelity bonds on LN to prevent denial of service attacks, summarizes a PR to address a fee siphoning attack that could affect LN channels using anchor outputs, and links to a proposed specification for miniscript. However, the proposal for tapscript would make it possible for an attacker to use the inefficiency to create blocks with transactions that could take a large amount of CPU to verify. The mailing list post does note that a significant amount of work would need to be done to implement the idea, including the development of a privacy-preserving cryptographic proof.
No significant news about Bitcoin infrastructure development this week. Floating Pair Options are contracts by which the better performing stock is determined by the Stock Pair’s relative value at a predefined date and time (usually beginning of a day, a week or month). Each routing node could then publicly announce its policy on how much value it would route given proof of a certain stake value. A downside is that channels with only small amounts of value (and thus small reserves) will be limited to only forwarding a small number of HTLCs simultaneously. Clients subscribed to these notifications will receive updates on both definitively resolved HTLCs and confirmed bitcoin transactions, allowing them to construct a canonical ledger for 바이낸스 OTP (Read the Full Post) coin movements through their C-Lightning node. 115, a recent update to the LN specification that has not yet been widely deployed makes it possible for an attacker to steal a portion of the bitcoins allocated to paying onchain fees for LN payments (HTLCs). ● HWI 1.2.1 is a maintenance release that provides compatibility with a recent version of Ledger’s firmware and improves compatibility with the BitBox02.
● Proposed watchtower BOLT has been updated: Sergi Delgado Segura emailed the Lightning-Dev mailing list an updated version of a suggested protocol for watchtower communication. This week’s newsletter describes a proposed LN feature to allow making spontaneous payments and provides our longest-ever list of notable code changes to popular Bitcoin infrastructure projects. In the years since the paper’s publication, people all over the world have been building on top of the open-source technology and contributing to improve the underlying computer code with the goal of making the network more robust. The PR description says that “the new algorithm consistently finds more routes and cheaper ones. 797 changes the way payment routes are calculated. With the updated logic, half of the protected slots are allocated to any onion and localhost peers, with onion peers receiving precedence over localhost peers. 139), a next step will be to extend eviction protection to I2P peers, as they generally have higher latency than onion peers. Subsequent to this merge, a new PR was opened that will make experimenting with dual-funding more accessible by eliminating the need to compile C-Lightning with special build flags (although a special configuration option will still be required). Regular spikes in the bitcoin price chart make this digital cryptocurrency a potentially lucrative investment if you’re interested in making a quick profit.
