One Word: Dogecoin

The Dandelion protocol is expected to make it extremely difficult for an adversary to determine the IP address of any program that creates a Bitcoin transaction (even if they don’t use Tor), but the new method of handling unconfirmed transactions privately for a time during the "stem" phase has to be secured against attacks that could waste node bandwidth and memory. ● Dandelion protocol DoS-resistant stem routing being worked on by Suhas Daftuar. ● RISC-V support being worked on by Wladimir van der Laan. ● Bandwidth-efficient set reconciliation protocol for transactions being worked on by Gregory Maxwell, Gleb Naumenko, and Pieter Wuille. ● Discussion of arbitrary contracts over LN: a thread on the Lightning Network (LN) development mailing list last week described the basic principles for performing arbitrary Bitcoin contracts in a payment channel. Maxwell is also working on making it possible for a newly-started (or long-disconnected) node to efficiently sync the high feerate part of its mempool from its peers using this same basic mechanism. If the changes are adopted, some of the notable advantages include: m.blog.naver.com making it easier for hardware wallets to securely participate in CoinJoin-style transactions as well as other smart contracts, potentially easier fee bumping by any individual party in a multiparty transaction, and preventing counter parties and third parties to sophisticated smart contracts from bloating the size of multiparty transactions in a DoS attack that lowers a transaction’s fee priority.

This week’s newsletter includes a request to help test the next version of Bitcoin Core, short descriptions of projects Bitcoin Core contributors are working on, and a list of notable merges during the past week. This week’s newsletter includes the usual dashboard and action items, a link to discussion about generalized Bitcoin contracts over Lightning Network, a brief description of a recently-announced library for scalability-enhancing BLS signatures, and some notable commits from the Bitcoin Core, LND, and C-Lightning projects. Finally, BLS signatures have only been around for about half as long as Schnorr signatures, are even less commonly used, and are not believed to have received the same amount of expert review as Schnorr signatures. In reality, many of the top Dogecoin wallets are cold wallets or hot wallets controlled by … The support would also be compatible with timelocks and hashlocks for use with LN-compatible wallets (hardware or software).

The Bitcoin Core project, like most free and open source software projects, is organized bottom-up with each contributor working on the things they think are important rather than top-down with project leaders directing the work, so occasionally-as happened last week-developers briefly summarize to each other what they’re working on for the future. Still, this open source library gives developers a convenient way to begin experimenting with BLS signatures and even start to use them in applications that don’t need to be as secure as the Bitcoin network. This is a CPU architecture rapidly increasing in popularity as a potential competitor with ARM-based chipsets, especially among hobbyists as the CPU design is open source. Meanwhile, the United States is exploring the potential repercussions of establishing its own digital currency. The currency has been subject to wild fluctuations in the past. The draft even explicitly allocates the XBT currency code to Bitcoin. 14180 (Run all tests even if wallet is not compiled) are part of a long-term effort to disentangle the wallet code from the server code. Depending on the exchange or wallet you are using, you may need to dig deeper into your transaction information to find the transaction ID.

Doing so provides a number of benefits including easier code maintenance, better opportunities for testing individual components, and potentially more secure software if the wallet component is moved to its own process.
