IN THE FIELD GUIDE
sigilbase
sigilbase.io
Sigilbase is a tamper-evident audit log system that stores records in a neutral third-party ledger, allowing offline verification with an open-source tool. It guarantees that once events are written, they cannot be changed, deleted, or reordered without detection, providing cryptographic proof of integrity and continuity.
