ISO publishes the first global blockchain interoperability framework, marking a decade-long effort led by Quant CEO Gilbert Verdian.

March 14, 2026 – Blockchain interoperability has long been one of the biggest barriers to institutional adoption of distributed ledger technology. Different networks often operate in isolation, limiting communication between ecosystems and preventing seamless enterprise integration. That landscape may now shift after a major milestone announced by Gilbert Verdian, CEO of Quant Network.

@gverdian 10 years ago someone said they would create a global ISO standard for blockchain. Today in 2026, the ISO blockchain interoperability standard is officially published. The internet only exploded after standards were established. Blockchain is now standing at that same inflection
A decade in the making, we have published an ISO standard for blockchain interoperability. This is a milestone I've been working towards since 2015, Remitt was founded with the conviction that blockchains could transform financial services but only if the industry solved

@gverdian Congrats Gilbert! I've been with you since pre-ICO days in 2018. Much hard work coming into fruition!

@gverdian @quantnetwork Congrats on the progress Gilbert. Crazy to think your guys work on ISO TC 307 has been going on for a decade now. Only began following in 2020 but the progress has been incredible to watch. Excited to see how this continues to develop and the growing role of Quant as always!

Steady attention without excessive speculation.
On March 14, 2026, Verdian confirmed the publication of ISO/TS 23516:2026, the first international interoperability framework for blockchain and distributed ledger technology.
The standard was developed under International Organization for Standardization Technical Committee 307, which focuses on blockchain standards.
The framework defines how distributed ledger systems can communicate with each other and with external networks. It outlines guidelines for cross-chain interoperability without requiring individual blockchains to modify their underlying architecture.
Verdian stated that the release concludes a decade-long effort that began in 2016 when his company, then called Remitt, proposed the first formal blockchain standard to ISO.
For institutions, interoperability remains a key requirement for adopting blockchain infrastructure. Banks, payment networks, and enterprise platforms often rely on multiple systems that must communicate securely.
The new standard aims to create a common framework that allows different DLT networks to connect through standardized interfaces. This approach could reduce fragmentation and accelerate enterprise deployment.
For the broader blockchain ecosystem, standards can increase confidence among regulators, governments, and corporate technology teams. Global standards bodies often shape the rules that guide large-scale technology adoption.
Verdian’s company, Quant Network, has already built infrastructure aligned with this vision through its Overledger platform. The system aims to connect multiple blockchains through gateway-based architecture.
Blockchain interoperability has become a major focus across the industry. Projects and protocols increasingly compete to connect fragmented networks while maintaining security and scalability.
ISO’s Technical Committee 307 was established in 2016 to coordinate global blockchain standards. Experts from multiple countries contributed to working groups that examined governance, terminology, security, and interoperability.
The publication of ISO/TS 23516 marks the first dedicated international framework addressing cross-chain communication. The standard builds on nearly a decade of collaboration among technical experts, governments, and industry leaders.
Further standards and implementations are expected as organizations refine interoperability models and apply them to real-world financial infrastructure.
