The release notes do warn that PSBTs generated by this version of C-Lightning will be rejected by some older versions of Bitcoin Core (versions 0.20.0 and earlier); this is a consequence of a change made to the PSBT specification and Bitcoin Core to defend against a possible fee overpayment attack. Michael Folkson outlines the benefits of Russell Yanofsky’s efforts to separate Bitcoin Core into different bitcoin-node, bitcoin-wallet, and bitcoin-gui processes. Michael Folkson explains the considerations involving a potential testnet reset or introduction of a new signet network. Andrew Chow explains that not only can you pay a zero-value amount to an address or other script, you can also spend from a zero-value output-but only if you find a miner who doesn’t use the default settings in Bitcoin Core. In the aftermath of the incident, a spokesperson for the United States Treasury Department underlined that crypto exchanges that handle money from blacklisted crypto address risk sanctions. 797 change how node address announcements are handled. Some sample commands are provided by cdecker for C-lightning to either rebroadcast the funding transaction or create a double spend. This week, BIP143 co-author Johnson Lau posted some suggested changes to sighash flags, including new flags, that could be implemented as a soft fork using the witness script update mechanism provided as part of segwit.

Of course, the most important feature provided by Binance is the ability to exchange between different cryptocurrencies. Cryptocurrencies have been swept up in a sell-off across higher-risk assets, which has picked up steam this week as data showed US inflation running hot, deepening investor fears about the economic impact of aggressive central bank tightening. Notable changes this week in Bitcoin Core, LND, C-Lightning, Eclair, libsecp256k1, Bitcoin Improvement Proposals (BIPs), and Lightning BOLTs. No noteworthy news to report this week. I don't think I will discuss the details here. Plugin authors wishing to ensure their plugin’s relative load ordering in this way should amend their getmanifest method’s response as shown here. For more information, place the cursor over the Connection Type field name to see the tooltip shown below. In 2014, the price fell sharply, and as of April remained depressed at little more than half 2013 prices. 0.9% on June 26 from over 22% in April after the exchange gave its customers a deadline of June 13 to withdraw their dollar funds as the SEC asked a court to freeze its assets. Roose, Kevin (8 April 2013). "Inside the Bitcoin Bubble: A Q&A With BitInstant's Stressed-Out CEO". This is a breaking API change for users of any of the updated fields.

BTC/kB to sat/vB. Users are warned that the latter is a breaking API change, but it should be relatively benign. With this change, up to that amount can be allocated to the initial part of the payment instead of splitting it across multiple paths. Bitcoin, which is the work of the psuedonymous Satoshi Nakamoto, is an extremely clever innovation and invention comprising multiple features and cutting edge new concepts, not fully realised in any previous electronic cash scheme. It fixes an edge case that could lead to accidental channel closure and a bug that could cause some payments to fail unnecessarily, plus some other minor improvements and bug fixes. It contains new content from Youtu features, updated options, and bug fixes. ● Upgrade to LND 0.5.2: this minor-version release fixes bugs related to stability and improves compatibility with other LN software. By contrast, the default coin selection algorithm in LND spends higher value UTXOs before lower value UTXOs; this minimizes fees in the short term but may result in needing to pay higher fees in the future when all inputs near the size of a transaction, or larger, have already been spent. ● What are the sizes of single-sig and 2-of-3 multisig taproot inputs?

To ensure that the latest state is recorded onchain, a channel should be unilaterally closed when there are only this many blocks until an LN payment has to be settled. In that sense, the protocol acts as a sort of generalized channel factory that applies not just to LN but to many protocols that create onchain transactions with unique fingerprints. 4171 updates the hsmtool command with a new dumponchaindescriptors parameter that prints the output script descriptors for the keys and scripts used by C-Lightning’s onchain wallet. In a particularly interesting section of his talk, Kotliar shows how perhaps as much as 70% of current onchain payments are users moving money from one exchange to another exchange (or even between different users of the same exchange). Bitcoin is pseudonymous, meaning that funds are not tied to real-world entities but rather bitcoin addresses. ● Backdoored VM images: a user on Reddit posted about losing funds after using an AWS image that came with a Bitcoin full node already installed and synced to a recent block. In the thread, Christian Decker notes that both current watchtowers (as implemented by LND) and future watchtowers for eltoo can have essentially O(1) costs (fixed costs) per user by having each person use a session key to update their latest state information on the watchtower.
