In the meantime, Johan Halseth posted to the Lightning-Dev mailing listing this week a couple of PR he opened to LND that may only accept a cost if the utmost amount of charges a peer can steal from that payment (and all previously accepted pending funds) is less than the channel reserve-the minimal amount that have to be stored in each aspect of a channel to function a penalty in case an previous state is broadcast. 120), Bastien Teinturier posted a proposal to have each the social gathering offering an HTLC and the celebration receiving it each pay charges to the opposite-although the receiving social gathering receives a refund on their fees if the fee is settled inside a specified amount of time. Any intermediate hop who doubts the fee will succeed before the deadline will now reject the cost, allowing earlier hops to also settle the failed payment earlier than the deadline and receive their refund.

● How will the migration software from a Bitcoin Core legacy wallet to a scriptptor wallet work? The legacy feeRate possibility in RPCs fundrawtransaction and walletcreatefundedpsbt still exists for setting a feerate in BTC/kvB; it is anticipated to be deprecated soon to avoid confusion. Michael Folkson outlines how a instrument that migrates present legacy wallets to scriptptor wallets might work. Michael Folkson summarizes fuzz testing, a technique of feeding a program like Bitcoin Core various malformed inputs for purposes of finding bugs. ● What's fuzz testing? ● Formal specification oscriptscript: Dmitry Petukhov revealed a formal specification of miniscipt based mostly on the documentation written by other builders. 115, a recent update to the LN specification that has not yet been broadly deployed makes it possible for an attacker to steal a portion of the bitcoins allotted to paying onchain fees for LN payments (HTLCs). Halseth’s PR makes an attempt to mitigate this by not requesting feerate will increase above 10 sat/vbyte, maintaining HTLC charges low so that the charges from a number of HTLCs are much less prone to exceed reserves. A draw back is that channels with solely small quantities of value (and thus small reserves) will likely be restricted to solely forwarding a small number of HTLCs simultaneous

If that is reflective of the opinions of the remaining pools, then it should be straightforward to accomplish the activation of taproot after its implementation has been launched and adopted by a average number of customers. ● Website itemizing miner assist for taproot activation: Bitcoin mining pool Poolin has created an internet site to help track miner help for activating taproot (together with schnorr signaturescripttapscript). This week’s e-newsletter hyperlinks to an similar internet site site that tracks miner help for taproot activation, announces a brand new organization funding Bitcoin analysis and improvement, and includes our regular sections with common questions and answers from the Bitcoin Stack Exchange, announcements of releases and release candidates, and notable modifications to standard Bitcoin infrastructure software program. This week’s newsletter summarizes a dialogue about bi-directional upfront charges for LN and relays the outcomes of a small survey amongst experts about their preferences for taproot activation. ● Taproot activation survey outcomes: Anthony Towns acquired survey responses from an unnamed set of thirteen "smart dev-type people" about their preferences for a comfortable fork activation mechanism to use with taproot. A quick survey of the curiosity stage within the neighborhood is an effective place
in.

The directional sample of the twin-quad was just as good as that of the reference quad. 4171 updates the hsmtool command with a new scriptchaindescriptors parameter that printscriptoutscriptript descriptors for scriptys and scripts used by C-Lightning’s onchain wallet. 4715 adds a --reset-wallet-transactions configuration parameter that can take away all onchain transactions from LND’s wallet after which begin a rescan of the block chain to repopulate the wscript These descriptors could then be imported right into a watch-only wallet to track any onchain transactions made by the LN node. Briefly, please consider performing further diligence on any software program or service to which you will entrust the creation of non-reversible Bitcoin transactions. The discharge notes do warn that PSBTs generated by this version of C-Lightning will probably be rejected by some older variations 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 towards a possible fee overpayment attack. Payment secrets are supported by all LN implementations and will eventually be made obligatory by C-Lightning; logging which payments are using fee secrets makes it easier for the builders to know when it’s reasonable to make that change.
