There are quite a few bitcoin wallet providers out there. There are traders who follow the global news and events on Bitcoin to make trading decisions; they often make great money. Nelson Wang is CoinDesk’s news editor website (straight from the source) for the East Coast. A future change to LDK may close channels with feerates that are too low, and work on proposals like package relay may make anchor outputs or similar techniques adaptable enough to eliminate concerns about present feerates. 1852 accepts a feerate increase proposed by a channel peer even if that feerate isn’t high enough to safely keep the channel open at present. ● 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. Replies from Pavol Rusnak and Craig Raw indicated that Trezor Wallet and Sparrow Wallet already supported the scheme Chow proposed.
The second address would be for internal payments within the wallet, namely returning change back to the wallet after spending a UTXO. An external path used for receiving payments might be shared with less-trusted devices, e.g. uploading it to a webserver to receive payments. The first path would be for generating addresses to which incoming payments could be received. The internal path used only for change might only be needed at times when the private key is also needed, so it could receive the same security. The module for reconstructing a public key from a signature is still not built by default “because we don’t recommend ECDSA recovery for new protocols. By themselves, the MuSig family of multisignature schemes only give you n-of-n signing-every party who contributes a key towards the aggregated public key must also contribute a partial signature to the final signature. 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.
Binance Coin can be bought on the Binance exchange using another cryptocurrency, or it can be bought on several other exchanges. Many investors like Binance because they offer coins like IOTA and Waltonchain that often aren’t listed on many other exchanges. As such, you can trust an exchange if it has mechanisms in place to prevent such hacks, such as storing coins in cold wallets. To simplify: You can imagine Bitcoin as a distributed spreadsheet, whereas Ethereum is more akin to a computer (VBA might be a better analogy, if you’re familiar with it). The Ethereum Foundation developers are great, but the hard fork code was unduly rushed and has some issues. And that’s a risk the exchanges are taking. In light of what happened with FTX, Binance’s CZ suggested that crypto exchanges should implement some measures to assure customers of the safety of their funds. Need to know what happened in crypto today?
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. 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. The attacker eventually sent out tweets from 130 different high-profile twitter accounts in order to acquire Bitcoin. As specified in BIP32, most wallets use separate paths for generating external versus internal addresses in order to enhance privacy. Kozlik’s scheme is closer in spirit to BIP70 but drops its use of X.509 certificates and adds features for exchange-based coin swaps (e.g. trading BTC for an altcoin or vice-versa). Thus, there are various implications that can be considered important for traders when trading. Discussion participants seemed to all favor providing an equivocation proof, although there was some concern that it could be too much work for the v0 specification.
