Cryptocurrencies - What Is It?

● Bitcoin Core 0.20.0rc2 is the most recent release candidate for the next major version of Bitcoin Core. ● LND 0.10.1-beta.rc1 is the first release candidate for the next maintenance release of LND. ● Bitcoin Core 0.20.0rc2 is the newest release candidate for the next major https://m.blog.naver.com version of Bitcoin Core. ● Breez wallet enables spontaneous payments: Version 0.9 of Breez wallet adds the ability to send spontaneous payments to Lightning nodes that support keysend. The feature is only enabled after the wallet observes the transaction remaining unconfirmed for four hours. Anchor outputs also provide greater security because, if feerates do increase beyond what was predicted, the node can fee bump its commitment transaction. 688 adds support for anchor outputs to the LN specification. Various degrees of support for anchor outputs have already been merged into several LN implementations. Cryptocurrencies are getting widespread acceptance and have seen a huge growth in recent times.

Also included are our regular sections describing release candidates and changes to popular Bitcoin infrastructure software. Advantages of the protocol are that it requires less block space than existing protocols, it saves on transaction fees (both by using less block space and potentially by requiring less urgency for its settlement transactions), it only requires consensus-enforced timelocks on one of the chains in a cross-chain swap, and it doesn’t depend on any new security assumptions or Bitcoin consensus changes. Notable changes this week in Bitcoin Core, C-Lightning, Eclair, LND, Rust-Lightning, libsecp256k1, Bitcoin Improvement Proposals (BIPs), and Lightning BOLTs. ● Lightning Loop using multipath payments: The latest upgrade from Lightning Labs now uses multipath payments to convert onchain funds into funds within LN channels. Pieter Wuille describes some of the downsides of using RFC6979 and why BIP340 uses a simpler nonce-generation algorithm inspired by Ed25519. Corallo also worries that using BIP8 from the start of a soft fork deployment gives the impression that the developers of node software get to decide the rules of the system.

● Copay enables CPFP for incoming transactions: Version 9.3.0 adds the ability for the user to speed up an incoming transaction using child-pays-for-parent. ● What are the sizes of single-sig and 2-of-3 multisig taproot inputs? ● Minimum transaction size discussion: Thomas Voegtlin posted to the Bitcoin-Dev mailing list about creating transactions with stripped sizes (non-witness sizes) as small as 60 bytes. 785 updates the minimum CLTV expiry delta to 18 blocks. This new minimum should help prevent inexperienced users from naively setting an unsafe value. This has led some LN implementations to use route-finding algorithms that optimize for routes with low CLTV expiry deltas, which has in turn led some users to set their deltas to values that are especially unsafe. This new major version allows accepting large channels (by default, this is off) and contains numerous improvements to its backend features that may be of interest to advanced users (see the release notes). Somsen’s SAS protocol leaves each party holding coins that they can spend at any time-but which they may need to spend on short notice if their counterparty attempts theft (similar to how LN channels need to be monitored).

They may also provide valuable information to assist the police and investigators in tracking the individuals or entities behind the theft. 96 for a summary of broadcast tracking). For privacy, the broadcast status of a transaction is only tracked if it was submitted by either the node’s wallet or the sendrawtransaction RPC. 17681 allows the wallet to internally derive new addresses for a BIP32 HD wallet seed even after that seed is no longer the wallet’s active seed.
