Introduction The FROST scheme is based on Verifiable Secret Sharing, where signers first perform Shamir Secret Sharing in homomorphic space, then each signer stores the generated share it has of the final key. However, this is slightly undesirable compared…

A clockless vardiff strands a slowing miner A note on where this came from. This began as an attempt to optimize vardiff, not to write about it. We were building a controller to track a miner more tightly, and noticed that an asymmetric response — quick…

Summary This post details two distinct Denial-of-Service (DoS) vulnerabilities discovered in Core Lightning (CLN). Both vulnerabilities allowed a remote peer to trigger unbounded memory growth, ultimately leading to Out-of-Memory (OOM) system crashes. The…

Bitcoin Core version 31.1 is now available from: https://bitcoincore.org/bin/bitcoin-core-31.1/ This release includes various bug fixes and performance improvements, as well as updated translations. Please report bugs using the issue tracker at GitHub:…

Neat idea, basically taproot but with a hash. Yeah that could be an option, but like @sipa points out, it would only be quantum-secure before the first spend. This would essentially be trading standalone PQ safety for 32 bytes more efficient EC spending…

I’m sharing a small proof-of-concept for zkPoH, a Zero-Knowledge Proof of Hodl system for Bitcoin. The idea is simple: prove that you control a set of Bitcoin UTXOs whose combined value is at least 1 BTC, without revealing the UTXOs, addresses, exact balance…

Originally published on my site. Replicating here because I think the Delving audience has an interest in this work. From the project’s inception until now, btc-verified has been focused on building up, layer by layer, a very minimal model of consensus.…

I’d like feedback on a draft that standardizes the policy a co-signer enforces, not the co-signer itself. A co-signer that signs only when a predicate holds is a known way to emulate covenants today. Towns described the multisig version of this in 2021.…

Abstract. BIP-352 does not recommend FROST- / MuSig2-based inputs “due to lack of a security proof”. This post describes a protocol that lets a multiparty sender perform a secure Silent Payment: the wallet computes an ECDH share as a weighted sum of the signers’…

Bitcoin payments are now spread across many so-called “layers”, and there isn’t a sufficiently generic way to make payments between them. In most cases, each layer has to run a Lightning node, and its users are more or less dependent on that node’s operator…

Hello Conduition, I fully agree with you that improving security and privacy and performance are worthy goals, though we’re living in the mere world of engineering where there is never a free lunch. Where I can be skeptical, it’s on the wallet and node complexity…

One useful control would be to compare reconstruction outcomes for the same block across nodes, split by high- versus low-bandwidth mode. That holds the block’s transaction set constant and helps separate mempool-policy effects from differences in announcement…

Why bitcoin payments haven’t taken off, and a call for moonshot ideas that could change that “If [bitcoin] ends up just being digital gold, I think it’s failed,” Jack Dorsey said in January 2025. “If it ends up being a currency that people can use daily…
