Four Actionable Recommendations on Bitcoin And Twitter.

Four Actionable Recommendations on Bitcoin And Twitter.

Binance is giving away 10,000 DOGE. Crypto exchange Binance is reportedly being investigated by the U.S. All you have to do is to set the parameters to your preference and the crypto trading bot will do the rest for you. If you are a novice trader and don't know much about grid trading and how to set a grid trading bot for Binance, you may consider a third-party crypto trading platform like CryptoHopper or TrailingCrypto. Patrick Hillmann, chief communications officer of Binance, said in a televised interview Monday that the company is aiming to protect the interest of customers by asking them to move their funds to the world’s largest crypto exchange by trade volume. Binance advisors, along with a review of company records, Reuters has pieced together the most comprehensive account so far of how the investigation developed and how Binance has sought to keep it at bay. The basic idea for fee accounts is that users could create transactions that deposited bitcoins into an account tracked by upgraded full nodes that understood the new consensus rules. ● Fee accounts: Jeremy Rubin posted to the Bitcoin-Dev mailing list the rough idea for a soft fork that could make it easier to add fees to presigned transactions, such as those used in LN and other contract protocols.

This week’s newsletter describes an idea to add accounts to Bitcoin for paying transaction fees and includes our regular sections with the summary of a Bitcoin Core PR Review Club meeting and descriptions of notable changes to popular Bitcoin infrastructure projects. This week’s newsletter describes how BLS signatures could be used to improve DLCs without consensus changes to Bitcoin and includes our regular sections with announcements of new software releases and release candidates, plus summaries of notable changes to popular Bitcoin infrastructure software. ● Core Lightning 0.11.2 is a bug fix release of the LN node. Version 0.9.1 was released to remove the network's vulnerability to the Heartbleed bug. Its release notes note that it includes breaking API changes but also numerous new features and bug fixes, including support for compact block relay data structures (BIP152) and improvements to taproot and PSBT support. 1088 adds the structures needed for compact blocks as specified in BIP152, as well as a method for creating a compact block from a regular block. 22751 adds a simulaterawtransaction RPC which accepts an array of unconfirmed transactions and returns how much BTC those transactions will add or subtract from the wallet’s balance.

It adds for invoice metadata which can be used by other programs (and potentially future versions of LND) for stateless invoices and adds support to the internal wallet for receiving and spending bitcoins to P2TR keyspend outputs, along with experimental MuSig2 support. Users can mine the bitcoins with computing power. After making the purchase, the bitcoins automatically transfer to your wallet. Replies from Pavol Rusnak and Craig Raw indicated that Trezor Wallet and Sparrow Wallet already supported the scheme Chow proposed. Although it’s already possible to refer to the key in those cases using the existing raw() descriptor, which is primarily meant to be used with tools like Bitcoin Core’s scantxoutset RPC for scanning its database of UTXOs, the new rawtr() descriptor makes it easier to use other existing descriptor fields to associate additional information with the taproot output such as key origin information. The key origin information may indicate that an alternative key generation scheme is being used, such as incremental tweaking to create vanity addresses or cooperative tweaking for privacy. 23480 updates the output script descriptor language with a rawtr() descriptor for referring to the exposed key in a taproot output in cases where either the key is used without a tweak (not recommended, see BIP341) or when the internal key and scripts aren’t known (which can be unsafe; see the PR comments or the documentation added by this PR for details).

The most significant of these is that it would allow "stateless" oracles where the parties to a contract (but not the oracle) could privately agree on what information they wanted the oracle to attest to, e.g. by specifying a program written in any programming language they knew the oracle would run. An external path used for receiving payments might be shared with less-trusted devices, m.blog.naver.com e.g. uploading it to a webserver to receive payments. If the example webserver were compromised and the external addresses were leaked, the attacker would learn about each time the user received money, how much they received, and when they initially spent the money-but they wouldn’t necessarily learn how much money was sent in the initial spend, and they also might not learn about any spends that entirely consisted of spending change. Dmitry Petukhov noted that only internal and external paths are widely used today and that any additional paths wouldn’t have a clear meaning to existing wallets. ● Multiple derivation path descriptors: Andrew Chow posted a proposed BIP to the Bitcoin-Dev mailing list for allowing a single descriptor to specify two related BIP32 paths for HD key generation.
