14291: For use with Bitcoin Core’s multiwallet mode, a new listwalletdir RPC can list all available wallets in the wallet directory. The noticeable difference is the number of European cities on the list. If this option is present, you should remove it and restart your node unless you have a good reason to believe all RPC connections to your node are encrypted or are exclusive to a trusted private network. Previously, using the -rpcallowip configuration option would cause Bitcoin Core to listen on all interfaces (although still only accepting connections from the allowed IP addresses); now, 바이낸스 OTP (find more) the -rpcbind configuration option also needs to be passed to specify the listening addresses. If the result is either “closed” or “filtered”, your node is safe unless you’ve set a custom RPC port or otherwise have enabled a customized configuration. For example, if you create the following configuration file using the name testnet instead of the correct name test, Bitcoin Core would previously silently ignore the testnet options. No new action items, but follow-up related to the following previously-published items is still recommended.
This week’s newsletter includes action items related to the security release of Bitcoin Core 0.16.3 and Bitcoin Core 0.17RC4, the newly-proposed BIP322, and Optech’s upcoming Paris workshop; a link to the C-Lightning 0.6.1 release, more information about BIP322, and some details about the Bustapay proposal; plus brief descriptions of notable merges in popular Bitcoin infrastructure projects. If such an attack was performed across the whole network, it might be able to prevent certain transactions from reaching miners, possibly breaking the security of protocols that rely on timely confirmation (e.g. LN payment channels). The Bitcoin consensus protocol doesn’t use ECDH, but it is used elsewhere with the same curve parameters as Bitcoin in schemes described in BIPs 47, 75, and 151 (old draft); Lightning BOLTs 4 and 8; and variously elsewhere such as Bitmessage, ElementsProject side chains using confidential transactions and assets, and some Ethereum smart contracts. Just like the internet uses TC/IP as an underlying protocol that makes just about everything else on the internet possible. In separate answers, Gregory Maxwell and Andrew Chow each describe the differences between these two proposed uses of Schnorr-based signatures. Pieter Wuille and Gregory Maxwell each answer a question about using Bitcoin private and public keys for encryption rather than their typical use for signing and verification.
● What makes batch verification of Schnorr signatures effective? Pieter Wuille provides a simple explanation for how it’s possible to do several multiplication operations simultaneously on an elliptic curve. ● Taproot and scriptless scripts both use Schnorr, but how are they different? 14424: Fixes a likely regression in 0.17.0 for watch-only wallets that require users to import their public keys for multisig scripts (rather than just importing the script) in order for Bitcoin Core to attempt spending the script using RPCs such as fundrawtransaction with the includeWatching flag. ● Upgrade to LND 0.5.2: this minor-version release fixes bugs related to stability and improves compatibility with other LN software. This allows bitcoin software to determine when a particular bitcoin was spent, which is needed to prevent double-spending. That may not sound exciting-the rsync tool has done that for over two decades-but libminisketch allows transferring the differences without knowing what they are ahead of time. 15226 adds a blank parameter to the createwallet RPC that allows creating a wallet without an HD seed or any private keys. 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.
Autopilot is the ability of the software to automatically suggest new channels to open when a user is first connecting to LN or wants additional spending capacity. In June 2021, the Taproot network software upgrade was approved, adding support for Schnorr signatures, improved functionality of Smart contracts and Lightning Network. 1. Developers assure themselves that the change is technically valid, positive and has broad support. Based on the examples collected, the report concludes with a summary of recommendations for developers. Satoshi seems to have forgotten to remove it, since sha.h is not used anywhere. My intent is to help you better understand the early details regarding the history of Bitcoin and the enigmatic figure of Satoshi Nakamoto. I then started looking at the getblockstats RPC for some additional stats while I figure out a way around this problem. At this point I spent more time writing code to get information out of InfluxDB then on inserting it into Postgres. The patch to getblockstats with these extra stats (and some more) is publicly available. This growth is largely due to more user adoption as wallets, platforms and services, DEXes and CEXes support BUSD.
