The South Asian nation of Bhutan is transitioning its self-sovereign ID system to Ethereum from Polygon, enabling its nearly 800,000 residents to authenticate their identities and access government services.
The integration with Ethereum is complete, and the shift of all resident credentials is expected to conclude by the first quarter of 2026, as stated by Ethereum Foundation President Aya Miyaguchi, who joined Ethereum co-founder Vitalik Buterin at the launch event with Bhutan’s prime minister, Tshering Tobgay, and crown prince, Jigme Namgyel Wangchuk.
“It’s incredibly motivating to witness a nation dedicated to empowering its citizens with self-sovereign identity,” Miyaguchi posted on X on Monday, noting that the Ethereum integration is a world-first.
“This achievement signifies a national milestone and a global step toward a more open and secure digital future.”
Integrating a blockchain-based system into a government’s national ID structure has long been promoted as a beneficial use case for cryptocurrency, due to its immutability, transparency, and privacy features, especially with the implementation of zero-knowledge proofs.
Ethereum becomes Bhutan’s third blockchain national ID solution
Bhutan previously operated its national ID system on Polygon since August 2024 and on Hyperledger Indy prior to that. Brazil and Vietnam are among the few other nations that have partially adopted blockchain-based self-sovereign identity systems so far.

Miyaguchi highlighted that Bhutan’s National Digital Identity and GovTech teams were instrumental in the Ethereum integration, along with contributions from the Bhutan crypto community.
Bhutan is accumulating Bitcoin
Bhutan — a nation that measures progress by Gross National Happiness — has quietly become a frontrunner in crypto adoption in recent years. It is currently the fifth-largest nation-state holder of Bitcoin, having accrued its assets through mining using renewable energy at its Himalayan hydropower plants.
It now possesses 11,286 Bitcoin valued at $1.31 billion, trailing only the US, China, the UK, and Ukraine, according to BitBo’s Bitcoin Treasuries data.
Bhutan may also be considering additional crypto initiatives, having met with former Binance CEO Changpeng Zhao in late September — although the specifics of their discussions remain undisclosed.
