Once this feature is finalized, users will be able to use their HWI-compatible hardware wallets directly from the Bitcoin Core GUI. ● Sparrow supports connecting to Bitcoin Core: Sparrow 0.9.10, using Bitcoin Wallet Tracker v0.2.1’s Java Native Interface bindings feature, now supports connecting directly to a backing Bitcoin Core node. ● LND 0.12.0-beta.rc5 is the latest release candidate for the next major version of this LN node. ● Coldcard adds payjoin signing: Coldcard’s 3.2.1 release adds BIP78 payjoin signing support and various multisig improvements. ● Payjoin adoption: Chris Belcher posted to the Bitcoin-Dev mailing list a request for people to look for ways to increase payjoin adoption along with a wiki page tracking the projects that provide either sending or receiving support for payjoin. This week’s newsletter summarizes posts to the Bitcoin-Dev mailing list about payjoin adoption and making hardware wallets compatible with more advanced Bitcoin features. This week’s newsletter links to a blog post about how a small change to the Script language after taproot activation could enable increased contract flexibility and includes our regular sections with notable changes to popular Bitcoin infrastructure projects. This week’s newsletter contains our regular sections with announcements of new releases and release candidates, plus notable changes to popular Bitcoin infrastructure projects.
Also included are our regular sections with overviews of changes to services and client software, new releases and release candidates, and youtu.be changes to popular Bitcoin infrastructure software. Notable changes this week in Bitcoin Core, C-Lightning, Eclair, LND, libsecp256k1, Rust-Lightning, Bitcoin Improvement Proposals (BIPs), and Lightning BOLTs. ” (see the notable changes section below). For a complete list of changes, see the release notes. ● C-Lightning 0.9.3rc2 is a release candidate for a new minor version of this LN node. ● Bitcoin Core 0.21.0 is a the next major version of this full node implementation and its associated wallet and other software. Before you can buy Bitcoins, you need to first get a Bitcoin wallet. This complex setup relies on the fact that there are businesspeople in Colombia – typically importers of international goods – who need U.S. There are many strategies to this type of additive RBF batching. In additive RBF batching, the service provider introduces new outputs (and confirmed inputs) to a transaction in the mempool to incorporate new customer withdrawals into an unconfirmed transaction. 4917 disables the use of anchor outputs by default, a feature that was planned to be released in the upcoming 0.12.0-beta. Advanced users can still opt-in to using anchors.
This enables the service provider to give users the experience of an instantaneous withdrawal while still retaining much of the fee savings from doing large batches of customer withdrawals at once. Technical problems: Binance has previously encountered technical problems, like as system outages and slowdowns during moments of high demand, which frustrated some users. Its high stability and less dependency on State institutions make it a powerful cryptocurrency in the Defi ecosystem. What is the All-Time High and All-Time Low of BTC? Similarly, RBF is useful for an enterprise who takes a fee-underbidding strategy (their initial transaction broadcast starts at a low fee, and is slowly bid upwards), but it exposes their customers to potential confusion as their withdrawal transaction updates in their wallet. For example, allowing a hardware wallet to handle in-channel LN payments or payments made from a vault. If blockchain technology is to be adopted globally, it should be able to handle much more data, and at faster speeds, so that more people can use the network without it becoming too slow or expensive to use. ● Making hardware wallets compatible with more advanced Bitcoin features: Kevin Loaec started a discussion on the Bitcoin-Dev mailing list about how hardware wallets could be changed to allow them to handle scripts more complicated than single-sig or multisig.
It also offers experimental support for wallets that natively use output script descriptors. His post does a good job of describing various problems that current hardware wallets can’t handle, but he notes that necessary “changes may be very difficult”. The Silkroad takedown in October may have not been powerful enough to pause the currency for the long-run, however, China’s latest policies regarding Bitcoin surely aren’t good for the once-regulation-free currency. However, when you combine RBF and “additive batching,” emergent edge cases and dangerous failure scenarios present themselves. In the base case, combining RBF and a single, static batch carries a simple combination of the complexities that RBF and batching carry discretely. At CardCoins we took a safety-first approach to our implementation (with the help of Matthew Zipkin), the details of which we described in a blog post, RBF Batching at CardCoins: Diving into the Mempool’s Dark Reorg Forest. For example, batching customer withdrawals may save on fees for the enterprise, but will likely make child pays for parent (CPFP) uneconomical for a customer who wishes to speed up the transaction. Replace By Fee (RBF, BIP125) and batching are two important tools for any enterprises directly interacting with Bitcoin’s mempool. Also included is extensive documentation for the new tools.
