<br> No significant news about Bitcoin infrastructure development this week. Notable changes this week in Bitcoin Core, C-Lightning, Eclair, LND, Rust-Lightning, libsecp256k1, Bitcoin Improvement Proposals (BIPs), and Lightning BOLTs. The discussion this week on the bitcoin-dev and lightning-dev mailing lists was about naming the sighash flag so that developers don’t use it accidentally without realizing its dangers. ● Two-transaction cross chain atomic swap or same-chain coinswap: Ruben Somsen posted to the Bitcoin-Dev mailing list and created a video describing a procedure for a trustless exchange of coins using only two transactions, named Succinct Atomic Swaps (SAS). ● Proposal for using one BIP32 keychain to seed multiple child keychains: several weeks ago, Ethan Kosakovsky posted to the Bitcoin-Dev mailing list a proposal for using one BIP32 Hierarchical Deterministic (HD) keychain to create seeds for child HD keychains that can be used in different contexts. ● Blockstream Satellite 2.0 supports initial block download: Blockstream outlines version 2.0 upgrades to their satellite service which include expanded Asia-Pacific coverage, additional bandwidth, and an updated protocol that enables a full node to complete an initial sync using only the satellite feed. Commenting on the protocol, Lloyd Fournier noted the “elegance” of a simplified version of the protocol that uses three transactions<br>p>
● Copay enables CPFP for incoming transactions: Version 9.3.0 adds the ability for the user to speed up an incoming transaction using child-pays-for-parent. 3821 adds anchor commitments for LN channels and enables them by default if both participating nodes of a channel signal support. 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. That way a user with multiple wallets can backup all of them using just the super-keychain’s seed (plus the derivation paths and the library for transforming deterministic entropy into input data). Users can control the maximum number of partial payments using an RPC parameter or command line option. ● Bitcoin Core 0.20.0rc1 the first release candidate for the next major version of Bitcoin Core is available for testing by experienced users. ● Lightning-based messenger application Juggernaut launches: In a blog post announcing the first release of Juggernaut, John Cantrell describes how the messaging and wallet features are built using keysend payments. Moreover, it has up-to-date information and academic centers where users can refer to whenever they encounter challenges while using their platform. Advantages of the protocol are that it requires less block space than existing protocols, it saves on transaction fees (both by using less block space and potentially by requiring less urgency for its settlement transactions), it only requires consensus-enforced timelocks on one of the chains in a cross-chain swap, 바이낸스 출금 방법 (please click the following webpage) and it doesn’t depend on any new security assumptions or Bitcoin con<br>u<br>hanges.
Both Binance and Globfoe take security very seriously. Depending on the exchange, personal identification can be required and may mean that you have to include a picture of a driver’s license or Social Security card, as well as information about your employer and source of funds. Andrew Chow and Raghav Sood clarify that a block header’s timestamp field is not required to have a greater value than previous blocks. Nodes that enable the compact block filter index with the -blockfilterindex configuration parameter can now respond to getcfcheckpt requests with a cfcheckpt compact block filters checkpoint response. This ensures that multi-homed nodes can better inform the network of their network connectivity. A network of communicating nodes running bitcoin software maintains the blockchain. The requirements are instead that a new block’s timestamp must be greater than the median timestamp of the past 11 blocks but no later than two hours after the present time according to the clock on the computer running the node. 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. ● Evaluate proposed changes to BIP341 taproot transaction digest: as described in last week’s newsletter, there has been a request for taproot signatures to make an additional commitment to the scriptPubKeys of all the UTXOs being spe<br>n<br>transaction.
At $11.81 per hour, house sitters make a little less. You have two separate chains, with overlapping sets of transactions, which would make any sort of ad-hoc hack to splice one chain onto the other impossibly hard, even if the anarchists in the Bitcoin world could agree to it. The idea is that in Schnorr you can take a bunch of keys together and have a single signature that proves all of them signed. If you have the financial means, you could also purchase an ASIC miner. The new logic will also ignore requests for types of data that aren’t expected to be sent over the current connection, such as requests for transactions on block-relay-only connections. This allowed an attacker who opens a large number of connections to your node to potentially delay your receipt of a transaction by a large number of two-minute intervals. As such, they’re typically used for short-term analysis by traders who are looking to profit from bursts of high volatility. Kosakovsky’s proposal is to create a super-keychain whose child keys are transformed into seeds, seed words, or other data that can be input into various wallets’ HD<br>chain recovery fields.
