Q.E.D. - Scalable, auditable and high-performance tamper-evident log

What's Q.E.D.

Q.E.D. is an open-source software that allows you to establish trust relations with others. It can be used in multiple scenarios:

• Secure tamper-evident data transfers,
• Tamper-evident (system/application/business)
• Logging
• ...

Q.E.D. 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.

Why Q.E.D.

Q.E.D. 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
