2024.9.13

1. The official BitVM project https://github.com/BitVM/BitVM/: The main branch has merged a PR submitted by the Fimma team: ~50% Optimization of Field Multiplication with Lookup Table, https://github.com/BitVM/BitVM/pull/89https://github.com/BitVM/BitVM/pull/89. This PR incorporates the algorithm proposed by Alpen.

   a. This optimization reduces the total script length by adding auxiliary variables. Although this PR has been merged, the code has not been applied to the zk verifier.

2. The Element Labs team submitted a PR: Upgrade to v3 graph, add musig2 signing, improve client #91, https://github.com/BitVM/BitVM/pull/91.

2024.9.11

1. The official BitVM project https://github.com/BitVM/BitVM/ has merged a PR submitted by the Citrea team: G1 scalar mul optimization #88, https://github.com/BitVM/BitVM/pull/88. This PR optimizes G1 scalar multiplication, reducing the size of scalar multiplication in the Groth16 verifier from 532m bytes to 295m bytes, an improvement of approximately 45%.
