Another building block we use: chainfold chainfold is a Rust library to deal with some of the inconveniences that come with handling on-chain events, especially reconciling after encountering a reorg. Instead of forcing you to use a specific runtime, a storage backend, or an arbitrary "safe" block height that can be considered finalized, chainfold puts these batteries in your hands, that you can tune according to your specific usecase. The design is simple enough: process an event, fold it into your local state, and when the block is finalized, persist the fold to storage, all while being able to roll back to a point that the data was known to be canonical. We built this library to enable easier legacy system integration, where codebases cannot use modern languages / libraries that are well maintained, and the developers end up having to rebuild most of these components themselves.
