● New research and development organization announced: Brink, a new organization for “funding, education, and mentoring” of Bitcoin contributors was announced on Twitter this week. Database storage and IPFS are mandatory for business and research. 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, announcements of releases and release candidates, and notable changes to popular Bitcoin infrastructure software. This week’s newsletter announces a meeting to discuss taproot activation mechanisms, includes a link to a Bitcoin Core usage survey, and includes our regular sections with top questions and answers from the Bitcoin Stack Exchange, a list of releases and release candidates, and descriptions of notable changes to popular Bitcoin infrastructure software. Please see Folkson’s email for background information about taproot activation mechanisms and a proposed agenda for the meeting. It has not yet been decided that BIP8 will actually be used for the activation, https://mootrade.com/unlocking-insights-join-the-discourse-at-the-coin-forum-for-crypto-enthusiasts/ so alternative proposals may also be discussed during the meeting or at a subsequent meeting. IRC channel on Freenode to discuss some desired revisions to BIP8.
In the meantime, Johan Halseth posted to the Lightning-Dev mailing list this week about a PR he opened to LND that will only accept a payment if the maximum amount of fees a peer can steal from that payment (and all previously accepted pending payments) is less than the channel reserve-the minimum amount that must be kept in each side of a channel to serve as a penalty in case an old state is broadcast. Until the payment eventually times out, each channel used to route the payment is unable to use those funds to route other user’s payments. 20981 has been opened to explore potential use cases for USDT probes in Bitcoin Core now that the framework has been merged. Windows and several Linux platforms were already supported, so the new Guix deterministic build system now supports all the same platforms as the existing Gitian system. Technical problems: Binance has previously encountered technical problems, like as system outages and slowdowns during moments of high demand, which frustrated some users. In that sense, Binance would operate similar to U.S.-based exchange Coinbase, where users have direct links to their bank accounts and can withdraw and deposit fiat.
Pieter Wuille describes a variety of nuanced considerations and incentives surrounding transaction propagation on the network concluding that no type of unconfirmed transaction can be trusted and users should wait for confirmations. ● Adding instead of concatenating hashes in Merkle trees Pieter Wuille breaks down a variety of issues to consider regarding the idea of combining hashes in a merkle tree using an operation such as addition instead of the concatenation that Bitcoin currently uses. The patch requires adding payment secrets to the invoices that LND produces. However, this requires an additional change to the LN specification that would need to be adopted by all implementations of anchor outputs. It requires minimal time and makes use of the efficiency of cryptocurrency. I’ve never liked ‘mixers’ like CoinJoin or CashShuffle, because they don’t match the way I want to use my ‘spending’ money. You are responsible for informing yourself about and observing any restrictions and/or requirements imposed with respect to the access to and use of any products and services offered by or available through Binance in each country or region from which they are accessed by you or on your behalf.
And I think there are certainly people opining on that, yes and no. So much of what judges do is that we rely on the parties that are before us to tell us what’s right and what’s wrong. If you think you are one of these projects, apply below! User Pseudonymous explains that while BIP37 bloom transaction filtering supports unconfirmed transactions, compact block filters have no such consideration and only service light clients with condensed block data since light clients have no way of verifying that unconfirmed transactions are valid. ● 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. 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). Since a route may cross more than a dozen channels, that means every bitcoin controlled by the attacker can prevent more than a dozen bitcoins belonging to honest nodes from being used for honest routing.
