v1.0.0

Bifrost Relayer v1.0.0

We proudly announce the release of a distinct version of the bifrost-relayer.rs for the Bifrost Network. This is not a mere upgrade of the existing Python version; rather, it's a fully reengineered implementation. The aim of this release is to bolster the network's decentralization and security through diverse relay implementations.

As a client-side tool, the bifrost-relayer.rs facilitates the Cross-Chain Communication Protocol (CCCP). It processes cross-chain transactions and facilitates data transfer (e.g. feeding price information) from one blockchain to another. While not entirely similar to other implementations, this new version significantly improves user convenience and robustness in handling unforeseen circumstances such as temporary failures or sudden spikes in gas costs - issues that were challenging to tackle in the existing version.
