Summary for December 2018
We’ve been taking a break for the past two months while working on a website upgrade. Since we did not cover news in that time, we decided to make a series of recap articles covering the last two months, starting with news related Bitcoin Core and going through Lightning Network and its related updates.

In the sections below, we provide brief overviews to some of the talks we think might be most interesting to this newsletter’s readers, but we also recommend watching the complete set of videos provided by the workshop organizers or reading the transcripts provided by Bryan Bishop.

BLS Library

A library has been released for BLS signature aggregation using a construction based on Musig. Musig is a scheme for non-interactive signature aggregation built on the Bellare-Nevan multisignature scheme which makes it possible to create just one public key from multiple public keys.

BLS signatures can be aggregated non-interactively although it makes the process slightly slower. They also have the same aggregation features with Schnorr signatures such as a resulting signature of constant size, reduced data size for easy validation and transmission on networks and high security.

This release is the first draft but is fully functional however it’s not yet reviewed for security.
