Bitcoin (BTC) is Internet money that can be transferred to and from anyone with an Internet connection. Bitcoin (BTC) is the most popular coin with 37% of crypto owners saying they hold BTC, according to Finder’s Cryptocurrency Adoption Index. The cryptocurrency climbed to as much as $14,095.61 on CoinDesk’s Bitcoin Price Index (BPI). His number one goal is to help you recover as much compensation as possible when you have been injured from a defective product. OpenSSL has been the source of previous vulnerabilities in Bitcoin Core (e.g. Heartbleed and non-strict signature encoding) and much effort over the past five-plus years has been invested into eliminating it as a dependency. The second RPC will verify a signed message from another node either using a pubkey provided by the user or by confirming the message is signed by a pubkey belonging head to M Blog Naver – https://m.blog.naver.com/ajjuguru/223161603998 any known LN node (e.g. a node in the set returned by the listnodes RPC). If the parties agree before creating the pubkey, they may also make it possible for fewer than all of them to sign, e.g. 2-of-3 of them must cooperate to sign. ● Upgrade to C-Lightning 0.7.3: this latest release adds support for a PostgreSQL backend, makes it possible to send funds directly to a particular address when closing a channel, and allows you keep your HD wallet seed encrypted when lightningd isn’t running-plus many other features and several bug fixes. Although this isn’t the near-universal support we’d like to see, it may be enough support that we’ll soon see more wallets switching to bech32 receiving addresses by default. We see that, in general, it takes longer for a transaction to confirm the less you pay-but users of segwit can often pay less per transaction for the same amount of waiting. ● LN simplified commitments: in two separate threads, developers of LND discussed their work on implementing simplified commitments, which are LN settlement transactions that only pay a minimal onchain transaction fee and which contain two additional outputs (one for each party). ● Will schnorr multi-signatures completely replace ECDSA? ● Taproot review: starting the first week of November, several Bitcoin contributors will be hosting a series of weekly meetings to help guide people through review of the proposed bip-schnorr, bip-taproot, and bip-tapscript changes. It also doesn’t help that it’s taught at a second grade level. After describing at length both the basic protocol and several possible variations, Bishop made a second post describing one case where it would still be possible to steal from the vaults, although he also suggests a partial mitigation that would limit losses to a percentage of the protected funds and he requests proposals for the smallest necessary change to Bitcoin’s consensus rules to fully miti risk.
Notable changes this week in Bitcoin Core, C-Lightning, Eclair, LND, libsecp256k1, Bitcoin Improvement Proposals (BIPs), and Lightning BOLTs. A presentation deck titled Lightning Implementation in Electrum by Thomas Voegtlin provides some background information and screenshots. ● Electrum Lightning support: In a series of commits this month, Electrum has merged support for Lightning Network into master. ● Blockstream Green Tor support: Version 3.2.4 of the Blockstream Green Wallet adds built-in Tor support for both iOS and Android. However, if you physically lose your hardware wallet without a key phrase backup, there is no other way of recovering your funds ever. However, such a reorganization would require an amount of proof of work roughly equal to the annual output of all active Bitcoin miners (at the time of writing), so this is considered to be both very unlikely and indicative of a threat that could prevent consensus formation anyway. However, this cryptocurrency logo takes it up a notch, by adding the two coins as inspiration and outlining the letter N between them. 1153 adds experimental support for multipath payments that allow a payment to be split into two or more parts that can be sent over different routes, allowing a user with multiple open channels to spend funds from each h channels.
● Upgrade to C-Lightning 0.7.2.1: this release contains several bug fixes as well as new features for plugin management and support for the in-development alternative to testnet, signet. ECDSA is required to spend non-segwit as well as segwit v0 outputs. Andrew Chow lists several considerations regarding public keys and quantum resistance, including: the need to reveal the public key during spending, the large number of bitcoins in outputs with known public keys, and numerous ways which public keys are exposed outside of just transacting due to not currently being treated as secrets. ● Why doesn’t RBF include restrictions on the outputs? ● Proposed change to schnorr pubkeys: Pieter Wuille started a thread on the Bitcoin-Dev mailing list requesting feedback on a proposal
