With 100% less blockchain.
I went searching for a lightweight immutable database that could be audited and ran into this.
I guess this is similar to XTDB and Datomic in Clojure-land, though they are maybe more full-featured and also look, kinda, heavier? AWS also has an immutable database offering that I didn’t know about, Amazon QLDB.
ImmuDB has an interesting and even surprising Postgres integration using Phoenix and Elixir: GitHub - codenotary/immudb-postgres-demo: immudb demo to track PostgreSQL table change history, though it’s from two years ago.
