πŸ”— The Security Tradeoffs of Validating Bridges
Building a secure bridge is one of the most difficult tasks in the crypto ecosystem. While there have been new developments in Bitcoin bridge designs, such as schemes relying on BitVM2 or BitVMX, the core problem remains the same.

02

UTXO Management has released its first 'State Of The Bridges' report, offering an in-depth analysis of the Bitcoin L2 landscape. The report explores the current and future potential of Layer 2 bridge designs, focusing on innovations like sidechains and rollups for scalability, while addressing technical challenges and adoption strategies.

πŸ”— State Of The Bridges 1
SOTB_1: An Overview of Bridge Designs for Bitcoin L2s<br/>As we enter of new era of development on Bitcoin, it has become very hard for most people to understand the nuances of the L2 debate, and ever harder to follow some of the technical jargon associated with it. Sidechains, Written by Guillaume Girard

03

A major breakthrough in multiplication over Bitcoin by the Starkware team with a new algorithm for M31 multiplication. This algorithm reduces multiplication cost by 70% without relying on OP_CAT.

πŸ”— Bitcoin as a Data Availability Layer: What, Why, How?
Rollups are fundamentally defined by data and the order in which that data is processed. As a result, the choice of a data availability layer is crucial to the trust model that underpins rollups. The integrity and security of rollups depend heavily on the safety and publishing guarantees provided.<br/>Written by Citrea Team
