Blockchain Audit Log and Event API
Build a searchable, sharable, and tamper-proof audit log or event-based history.
A tamper-proof audit log
Searchable & sharable
Build a tamper-proof audit log in minutes. With our flexible and scalable connector, any event emitted by other services can easily be added to your audit log.
How it works
Step 1
Transmit your events
Transmit events that matter to you. If you tested a vaccine, a customer made a payment, or an employee deleted a row in a database. You can build your audit trail just as you need it.
Step 2
Tamper-proofing
We take all events that we receive from your end and append them to your tamper-proof event history. Inserting, modifying, or updating event data afterward becomes impossible - thanks to blockchain technology.
Step 3
Search, filter & share
Once done, you can share your tamper-proof event-based history or audit log with internal stakeholders or external auditors. You can search and filter through all events in real time. And if you need a PDF of a filtered view, there is a 1-click export.

Why blockchain makes the difference.
Blockchain anchoring
Any event that is submitted is anchored to multiple public blockchains. This way, you can prove that an event was created at a specific time and not changed since. This proof doesn't expire, is independent of OriginStamp, and remains verifiable at all times.
Continous sealing
We chain each event to the predecessor event. As a result, it's impossible to insert, modify or delete any event from your event trail. In combination with blockchain anchoring, gapless sealing creates undeniable proof of integrity for your event trail.

What's included

White Labelling
Embed your logo and customize the Event API to your cooperate identity. Your users will identify the trail as related to your business, but it's still clearly visible that the data is transparently hosted and provided by OriginStamp.

Connect any Software
Connect any software with your tamper-proof audit log. Our solution integrates seamlessly into any software with no coding required. Plug-in via webhooks, form or app builder, or use our comprehensive API.

Share Links
Build trust by allowing transparent access for outside stakeholders like end-consumer or partners. Everyone possessing the share link can view your event trail and validate its consistency. These shared trails can also be made accessible within your own domain.
