QED - Scalable, auditable and high-performance tamper-evident log

User Documentation Status Build Status Azure DevOps coverage GoReport GoDoc
https://raw.githubusercontent.com/BBVA/qed/master/docs/source/_static/images/qed_logo_small.png

QED is an open-source software that allows you to establish trust relationships by leveraging verifiable cryptographic proofs.

It can be used in multiple scenarios:

  • Data transfers.
  • System (or application or business) logging.
  • Distributed business transactions.
  • Etc.

QED guarantees that the system itself, even when deployed into a non-trusted server, cannot be modified without being detected. It also provides verifiable cryptographic proofs in logarithmic relation (time and size) to the number of entries.

QED is scalable, resilient and ops friendly:

  • Designed to manage billions of events per shard
  • Over 2000 operations per second per shard under sustained load
  • Consistent replication through RAFT
  • Operable and instrumented with dozens of metrics
  • Zero config files, fully documented single binary
