Two analysts using different tools can reach opposite conclusions about whether two addresses belong to the same taxpayer. An attribution received from another administration carries no agreed way of stating on what basis, by what method or with what confidence it was made.
Service providers face the same uncertainty before they sign a report. That is not a data problem — it is a standards problem.
OBIS is an open, vendor-neutral set of specifications for blockchain intelligence — shared formats for attribution, method and confidence — developed in public and promoted by ICI Bucharest, the Complexity Science Hub Vienna and the Blockchain Intelligence Professionals Association (BIPA).
It certifies nobody, sells nothing and replaces no regulation: it sits beneath DAC8, CARF and the FATF Recommendations, in the technical layer where the absence of common formats costs everyone time and money.
The specifications are shaped through a series of roundtables across 2026 and 2027.
Register your interest in the Open Blockchain Intelligence Standards roundtables — Vienna, Frankfurt, Paris, Warsaw and the Bucharest launch. Open to tax authorities, supervisors, service providers and practitioners.
Registering interest carries no commitment, and there is no fee or membership.
Everyone who registers will be contacted by the organisers with further details about the relevant event; invitations are issued in the weeks before each roundtable.

05
Bucharest — 22 April 2027
The Blockchain Intelligence Forum, part of the Digital Innovation Summit Bucharest, where OBIS is formally launched and where authorities can formally join the project.
Registering interest carries no commitment, and there is no fee or membership. Everyone who registers will be contacted by the organisers with further details about the relevant event; invitations are issued in the weeks before each roundtable.
The organisers will contact you with further details about the roundtable(s) you selected.
In the meantime, the current OBIS drafts are public at obistandards.org and open to comment from anyone.
The standards will be written either way. The only question is whether the people who have to rely on them are in the room.
Participation is by invitation only, to ensure strategic depth, balanced representation and actionable institutional outcomes.
