For more information, Wuille links to a discussion between himself and several other Bitcoin cryptographers. A final discussion covered how and when to attempt to get BIP119 activated, including when a PR for it should be opened to the Bitcoin Core repository, what activation mechanism it should use (e.g. BIP9 versionbits), and what range of activation dates would be appropriate if it uses a miner-activated soft fork mechanism such as BIP9. Subsequent to the workshop, CTV proposer Jeremy Rubin announced a mailing list to help coordinate future review and discussion of the BIP119 proposal. CHECKTEMPLATEVERIFY (CTV) Workshop: video (morning, afternoon) and a transcript are available from a recent workshop about BIP119 CTV. They are based on both the tactics of trading- auto and manual analysis. A power analysis attack involves monitoring the amount of electricity a hardware wallet uses when it generates different signatures in order to potentially learn what private key was used (or to reveal enough information about the key that effective brute forcing becomes possible). BIP340 co-author Pieter Wuille replied with an explanation: in key and signature aggregation where a mathematical relationship is created between the private keys of cooperating users, the attacker-if he’s one of the cooperating users-may be able to combine knowledge of his private key with information learned from power analysis of other users’ signature generation in order to learn about the other users’ private keys

87 to update the BIP340 specification for schnorr signatures with a recommended nonce generation function that claims to be more resistant against differential power analysis. Several LN implementations were already announcing or allowing multiple addresses of a given type, so this change brings the BOLT specification in line with what the implementations were already doing. ● Where can I find the miniscript policy language specification? Anchor commitment transactions can be fee bumped unilaterally by either party, which is useful because commitment transactions might be broadcast a long time after they commit to their on-chain feerate. This limits the ability of a miner who is reorganizing (forking) the chain from being able to arbitrarily rearrange transactions to maximize their fee revenue. 2039 adds the ability to get the status of the autopilot functionality as well as allowing enabling or disabling it while the program is running. 88), Karl-Johan Alm has proposed a simplification that removes the ability to bundle together several signed messages for different scripts and also removes an unused abstraction that could’ve made it easier to extend the protocol for something similar to BIP127 proof of reser
Fixing the inefficiency now reduces the number of changes that need to be made in the proposed schnorr, taproot, and tapscript soft fork. If this proposed soft fork is adopted, users would be able to use a new CTV opcode to create covenants with less interaction than would be required using current consensus rules. This week’s newsletter summarizes an update to a proposed standard for LN and includes our regular sections about notable changes to services, client software, and popular Bitcoin infrastructure projects. ● 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. Anyone with feedback on the change is encouraged to either reply to the mailing list thread or to the PR updating the draft BIP. Several people replied to the thread with comments and suggested alternatives. 4) Litecoin(LTC): As one of the original altcoins (alternatives to bitcoin), Litecoin (LTC) is a cryptocurrency that was launched in 2011. Although LTC was developed to be better than BTC, particularly in terms of transaction speed, https://youtu.be/SfwkGRVF5GI it is based on the original source code of Bitcoin and shares some features wi

Each digital transaction is secured by cryptography that is saved in the ledger of a public distributor called Blockchain. When the time came today, the hackers initiated a mass withdrawal from these accounts, generating a massive 7,074 BTC transaction from Binance's main "hot wallet" to several smaller accounts. Enables users to exchange the best bitcoin wallet virtually anytime, anywhere. Your wallet can reside on your PC, Mac (such as MultiBit) or your smartphone, and there are also online wallet websites available. When using these lending products, you are usually lending cryptocurrency to traders who use it for margin trading. This reason alone is enticing the new traders and investors to pump money into it. Cryptographic forms of money like bitcoin give an interesting administration: Monetary exchanges that don't expect governments to issue cash or banks to process installments. Undereducated members of marginalized minority communities also might not want to use banks because they don't trust them. 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. It's kind of like saying an increased demand for hypersonic missiles will help make far more turboprops in future go faster.
