Notable changes this week in Bitcoin Core, C-Lightning, Eclair, LND, Rust-Lightning, libsecp256k1, Hardware Wallet Interface (HWI), Rust Bitcoin, BTCPay Server, Bitcoin Improvement Proposals (BIPs), and Lightning BOLTs. 16546 introduces a new signer interface, allowing Bitcoin Core to interact with external hardware signing devices through the HWI or any other application which implements the same interface. Bitcoin Core has been able to interface with hardware signers using HWI since Bitcoin Core version 0.18. Until this PR, however, the process required use of the command line to transfer data between Bitcoin Core and HWI. ALL, but the fact that they aren’t relayed or mined by default can theoretically be used to trick software using offchain commitments into accepting an unenforceable payment. Live chat is the best choice and this can be accessed any time of day using the live chat icon which can be found in the lower right of the screen. Best month since 1987 for stocks.
The combination of average inflation and relaxed financial conditions have been pushing stocks to all-time highs. The 1xBit sign-up code is valid for all countries accepted by 1xBit and for all sections they have. In addition to the use of cryptocurrency, 1xBit also allows you to bet on their website without the need to give any personal information. It is also worth mentioning that the website is not available for UK players, so unfortunately they are not able to use the bonuses at 1xBit, but for players from the UK we prepared a post regarding available promo codes for UK players, so you can check it now. Bitcoin is just one of the cryptocurrencies accepted, despite the website often being advertised as a Bitcoin bookmaker. Counterarguments included being able to get part of the proof from an onchain transaction (which requires that someone paid an onchain fee) and also that users could choose where they download fraud proofs from, preferring to get them from a source that was known for only propagating accurate information. As an intermediate solution, it was suggested to focus on proofs of lying. When the format of those proofs has been established, software can then be updated to take two separate proofs for the same oracle and event to create a proof of equivocation.
A proof of equivocation can be automatically verified by software without third-party trust. This will almost always depend on evidence not available to the user’s contract software, so this type of fraud proof must be verified manually by the user, who can compare the original contract to the outcome signed by the oracle. ● Lying: where an oracle signs for an outcome that users know is wrong. ● Equivocation: where an oracle signs for the same event more than once, producing conflicting results. ● Fraud proofs in the v0 Discreet Log Contract (DLC) specification: Thibaut Le Guilly started a discussion on the DLC-dev mailing list about the goal to include fraud proofs in the version 0 DLC coordination specification. This week’s newsletter describes discussion about a desired replacement for some of the features of the BIP70 payment protocol and summarizes proposals for a standardized way to exchange fraud proofs for Discreet Log Contracts (DLCs).
Voegtlin wants to be able to prove that the address he paid was actually the address provided to him by the receiver (e.g. an exchange). 135, BlockSource allows software to obtain data from sources other than a standard Bitcoin Core compatible node, allowing redundancy that can help prevent eclipse attacks or other security problems. As it became possible to relay payments to any segwit script in Bitcoin Core 0.19.0.1 (released November 2019), it’s now safe to include them in LN’s standard forms. This PR simplifies the user experience by enabling Bitcoin Core to directly communicate with HWI. The PR includes full documentation on how to use the new signer interface along with HWI. Hill’s scheme is intended for use with LNURL but could be repurposed to serve Voegtlin’s intended use case. To get this 1xBit bonus all you need to do is use the code ‘BCVIP’. If you enjoy in-play betting, 1xBit have you covered.
