The organization is seeking applicants for both its fellowship program for helping newer contributors break into full-time Bitcoin development and its grant program for funding established contributors. This week’s newsletter links to a website; www.youtube.com, 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. Also included are our regular sections with notable changes to services, client software, and infrastructure software. ● Wasabi uses a centralized coordinator who organizes every coinjoin made using that software. The coordinator uses this specified value to verify that the sum of the outputs the client wants to create is equal to the sum of the inputs provided by the client (minus fees). ● 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.
Payment secrets are supported by all LN implementations and will eventually be made compulsory by C-Lightning; logging which payments are using payment secrets makes it easier for the developers to know when it’s reasonable to make that change. Any intermediate hop who doubts the payment will succeed before the deadline will now reject the payment, allowing previous hops to also settle the failed payment before the deadline and receive their refund. Any ultimate receiver who wants to use hold invoices for longer than the remaining time will now need to pay the backwards fee. ● Joinmarket has two types of users: those who pay to coinjoin (market takers) and those who are paid for allowing their UTXOs to be used (market makers). Meanwhile, Bitcoin’s market cap was around $520bn, with resistance at $27,200 and support at $26,700, according to CoinMarketCap. As of this writing, all pools listed on the site-who represent more than half of the current network hash rate-have indicated that they will support activation. Compared to previous designs for payment pools (such as joinpool), the CoinPool design focuses on allowing participants to make offchain commitments to transactions between the members of the pool. 643 as part of the multipath payments feature to prevent probing attacks by nodes along the payment path.
For example, a taker can choose the amounts of the coinjoin they want to create or can spend their money to a third party as part of a coinjoin. The US Office of Foreign Assets Control listed two Iranians and their bitcoin addresses as part of its Specially Designated Nationals and Blocked Persons List for their role in the 2018 Atlanta cyberattack whose ransom was paid in bitcoin. Filter network traffic to prohibit ingress and egress communications with known malicious IP addresses. Litecoin follows an open source global payment network which cannot be accessed by any central authority. A .onion site, which is accessed via the TOR network, ensures that users are able to buy a subscription from this provider anonymously. This new major version allows accepting large channels (by default, this is off) and contains numerous improvements to its backend features that may be of interest to advanced users (see the release notes). It contains “new CLI-level notifications, better channel state reporting, and stable plugin-hook call ordering” in addition to other new features and bug fixes. This week, several contributors to Wasabi posted to the Bitcoin-Dev mailing list about a new protocol they call WabiSabi that conceptually extends their existing protocol with a technique adapted from confidential transactions.
Michael Folkson summarizes fuzz testing, a technique of feeding a program like Bitcoin Core varying malformed inputs for purposes of finding bugs. SECURETHEBAG, links to a proposal to standardize LN watchtowers, and summarizes notable changes to popular Bitcoin infrastructure projects. Finally, keep track of your cryptocurrencies’ values and be ready to make changes in response to market developments. There is something you need to be aware of when it comes to market orders – slippage. For many traders, it makes sense to trade Bitcoin which is one of the many cryptocurrencies out there. There are lots of things other than money which we consider valuable like gold and diamonds. While you might not be able to imagine in your mind’s eye all the terrible things that might happen with a fully monitorable currency, needless to say, it will contain what are, in effect, indescribable Lovecraftian monsters from the blackest Stygian depths.
