Postel’s Law is a psychological meme directed at software developers who need to write programs that interact with each other, typically via an exchange of messages in some «standard» format.

This week’s newsletter links to a website that tracks miner support for taproot activation, announces a new organization funding Bitcoin research and development, and includes our regular sections with popular questions and answers from the Bitcoin Stack Exchange, 바이낸스 보안설정 (homepage) announcements of releases and release candidates, and notable changes to popular Bitcoin infrastructure software. This week’s newsletter describes a proposal for using fidelity bonds on LN to prevent denial of service attacks, summarizes a PR to address a fee siphoning attack that could affect LN channels using anchor outputs, and links to a proposed specification for miniscript. ● Fidelity bonds for LN routing: Gleb Naumenko and Antoine Riard posted a to the Lightning-Dev mailing list to use stake certificates (another name for fidelity bonds) to prevent a type of channel jamming attack first described in 2015. These are attacks where a malicious user sends a payment to themselves or a confederate through a series of channels and then delays either accepting or rejecting the payment. ● Formal specification of miniscript: Dmitry Petukhov published a formal specification of miniscipt based on the documentation written by other developers.

115, a recent update to the LN specification that has not yet been widely deployed makes it possible for an attacker to steal a portion of the bitcoins allocated to paying onchain fees for LN payments (HTLCs). ● 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. ● New research and development organization announced: Brink, a new organization for «funding, education, and mentoring» of Bitcoin contributors was announced on Twitter this week. Pseudonymous analyst Cheds tells his 311,700 Twitter followers that Shiba Inu is currently witnessing a surge within a macro downtrend.

4908 ensures that channels using anchor outputs can fee-bump their commitment transactions on closure by enforcing a reserve balance in some instances. However, this requires an additional change to the LN specification that would need to be adopted by all implementations of anchor outputs. 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. Over 200,000 machines in 150 countries were affected by the attack. Other Payment Channels: These include other payment platforms like Skrill, iDEal, Sofort, etc. There are dozens of online payment providers, with different exchanges accepting different payment methods. So when all markets like stocks or commodities are falling, bitcoin is either stable or rising. Michael Folkson summarizes fuzz testing, a technique of feeding a program like Bitcoin Core varying malformed inputs for purposes of finding bugs.
