Bitcoin is a digital currency, with no physical bitcoins in circulation. Many contracts define a large number of possible terminal states, such as a contract about the future price of bitcoins which specify prices rounded to the nearest dollar and need to cover several thousand dollars worth of price range even for a relatively short-term contract. In brief, for each possible terminal state of a contract-e.g., Alice gets 1 BTC, Bob gets 2 BTC-DLCs currently require creating a separate signature adaptor for that state. CTV commits to outputs using hashes, so parties can compute all the possible state hashes themselves quickly and on-demand, minimizing computation, data exchange, and data storage. As far as the Bitcoin/legal situation, having a trading platform/secondary market where users can re-sell shares or assets they own is pretty much illegal unless you set up a registered stock exchange which would take tens of millions to do. It’s set up in a way that assets can flow freely between the two. It’s noble. And it’s so rare and so unique.
● Fee bumping research: Antoine Poinsot posted to the Bitcoin-Dev mailing list a detailed description of several concerns developers need to consider when choosing how to fee-bump presigned transactions used in vaults and contract protocols such as LN. In particular, O’Beirne is concerned that some of the transaction relay policy changes being proposed will complicate the use of fee bumping for users and wallet developers. More details on the anchor outputs-style fee bumping used by Eclair can be found here. Ensuring that fee bumping works reliably is a requirement for the safety of most contract protocols, and it remains a problem without any comprehensive solution yet. Third is that, for non-taproot inputs, the requirement of a single element on the stack after execution is only a policy rule, not a consensus rule. Finally, that policy rule applies only to the final stack after an input script is executed together with the corresponding output script. ● How can the genesis block contain arbitrary data on it if the script is invalid? Maybe you’re following what Marty and Matt are doing, and you can go into a “tribe” on Sphinx and you can stream them censorship-resistant private money on Lightning and nobody can stop you.
Following our initial reporting, another source corroborated that officials had visited one of the offices prior to the shutdown. ANYPREVOUT signature hash mode (and we’ll note that the same optimization is also available using the alternatives described in the following news item). ● Composable alternatives to CTV and youtu.be APO: Russell O’Connor posted to the Bitcoin-Dev mailing list the idea for a soft fork to add two new opcodes to Bitcoin’s Tapscript language. 5010 adds a language binding generation tool MsgGen and a Rust RPC client cln-rpc. MsgGen parses C-Lightning’s JSON-RPC schemas and generates the Rust bindings used by cln-rpc to correctly call the C-Lightning JSON-RPC interface. ● BTCPay Server 1.4.2 is the latest release in the new 1.4.x series, which includes improvements in login authentication and a number of user interface improvements. Also included are a number of simplifications over the existing LN gossip protocol, which is used to advertise the existence of public channels for routing. The updated protocol is designed to maximize efficiency, especially when combined with an erlay-like minisketch-based efficient gossip protocol.
The feeler connection is used to test potential new peers suggested from the gossip network as well as test previously unreachable peers which are candidates for eviction. User vnprc explains the purpose of Bitcoin Core’s feeler connection which is a temporary outbound connection separate from the default 8 outbound connections and 2 blocks-only outbound connections. ● What is a Feeler Connection? ● BDK 0.16.0 is a release that includes a number of bug fixes and small improvements. As mentioned earlier, Bitcoin is the oldest cryptocurrency and enjoys a first-mover advantage, but it also has a very active developer community (not to mention its solid design foundation) which means that Bitcoin coins to be number one cryptocurrency by market capitalization. CHECKTEMPLATEVERIFY (CTV) opcode could radically reduce the number of signatures required to create certain Discreet Log Contracts (DLCs), as well as reduce the number of some other operations. CHECKTEMPLATEVERIFY. Also included are our regular sections with selected questions and answers from the Bitcoin Stack Exchange and descriptions of notable changes to popular Bitcoin infrastructure projects. CHECKTEMPLATEVERIFY (CTV, specified in BIP119). 184) by choosing a more aggressive confirmation target when the wallet is low on UTXOs.
