The Importance of Chain Signatures & Atomicity

Just a few days after we dropped the chain abstraction market map, we come to you with an in-depth podcast about NEAR's chain signatures, which they recently announced as well.

As the crypto space continues to grow, so does the need for better ways to connect different blockchains.

Proximity, a project born from the NEAR ecosystem, has been working on a solution that could help simplify these connections. Their latest development, Chain Signatures, offers a way for smart contracts to sign transactions across various blockchains, making it easier to build and interact with apps that aren't limited to just one chain.

We were first introduced to this idea from Illia himself during Modular March, when we discussed the idea of account aggregation and chain abstraction.

However, what we learned on this podcast is the importance of atomicity. This is a technical term that means actions across different blockchains are either fully completed or not done at all, ensuring consistency and reducing the risk of errors (a chain re-org being the most catastrophic of problems when dealing with synchronizing state across different domains).

We touched on the security parameters of chain signatures as well. Proximity uses a decentralized Multi-Party Computation (MPC) network, where multiple independent operators hold pieces of a master key. This is a typical design we've see outside of the onchain landscape which adds a layer of protection and privacy when it comes to data.

Chain Signatures could offer new ways to build flexible, multi-chain applications without the usual headaches that come with cross-chain development. Still in the early stages, but NEAR has been a pioneer of chain abstraction for some time now.

Today, we'll take a closer look at how Chain Signatures function, why atomicity is so important, and how Proximity is paving the way for a more connected and user-friendly crypto environment.
