immudb is the blazing-fast and lightweight immutable key/value database to store sensitive data in a tamperproof manner. Able to process millions of write transactions per second, it is, therefore, able to track changes in any transactional system. Immudb avoids the complexity, expense, and low-thruput that plagues public blockchains by providing an indelible append-only ledger with cryptographic SHA256 verification.
immudb is open source and very easy to integrate using gRPC, language bindings for Java, Python, node.js, .NET and Go, or through a REST API Gateway. immudb runs on Linux, FreeBSD, Windows and macOS, on-premise or in the cloud.
