Forensic analysis discovers: Bitcoin halted 8 times at launch, Satoshi Nakamoto solo mined, first miners: Hal Finney vs. Dustin Trammell.

Visualizing post-quantum signature sizes. See the infrastructure tradeoffs.

A comprehensive analysis of potential attacks and undesirable outcomes resulting from a cryptographically relevant quantum computer being wielded against the Bitcoin network.

An argument in favor of burning bitcoin in vulnerable addresses to prevent funds from being taken by those who win the quantum computing race.

LeanIMT+ is a new Merkle tree construction that enables efficient membership and non-membership proofs without the overhead of Sparse Merkle Trees. By combining LeanIMT's dynamic depth with the linked-leaf approach of Indexed Merkle Trees, it delivers faster…

A collection of common mistakes when implementing MPC protocols, to help developers implement MPC securely.

This article focuses on the design space of post-quantum solutions for Ethereum users, centered on protecting assets and therefore on the execution layer. Our argument, in short: the best answer here is more than a signature, it's a protocol, a set of choices…
