Concensus Cleanup Demo

A demo to let end users see for themselves the impact of hard to validate blocks. We have crafted a series of 6 blocks that are hard to validate, but not too much. Each should take between a handful of seconds and one minute to validate, depending on the hardware. @ajtowns is going to mine the six blocks in a row and then reorg them out, so that anyone running a Signet node at the time would see them, but they would not impose a cost to IBD forever.

Channel Splicing Merged into BOLT Specifications

Splicing allows spending the current funding transaction to replace it with a new one that changes the capacity of the channel, allowing both peers to add or remove funds to/from their channel balance.

Judica Purify

Jeremy Rubin and Judica announces a white paper and reference library for Purify

Purify is a provably secure, circuit-friendly pseudorandom function (PRF) [3, 1]: the design pushes the expensive message hashing outside the arithmetic circuit while keeping the in-circuit work close to low-degree field arithmetic.
