不丹正將其自主開發的身份識別系統從Polygon遷移至以太坊，該系統可讓近80萬居民驗證身份並存取政府服務。目前，不丹與以太坊的整合已完成，預計所有居民憑證的遷移工作將在2026年第一季度完成。  

以太坊基金會主席Aya Miyaguchi與以太坊聯合創始人Vitalik Buterin共同出席了啟動儀式，與會者還包括不丹首相Tshering Tobgay及王儲Jigme Namgyel Wangchuk。Miyaguchi表示，這是全球首個國家級以太坊身份識別系統整合案例。  

此前，不丹自2024年8月起開始在Polygon上運行國家身份識別系統，而更早之前使用的則是Hyperledger Indy平台。

Bhutan is migrating its self-developed national identity system from Polygon to Ethereum. This system enables nearly 800,000 residents to verify their identities and access government services. Currently, the integration between Bhutan and Ethereum has been completed, and the migration of all residents' credentials is expected to be finished in the first quarter of 2026. 

Aya Miyaguchi, Chair of the Ethereum Foundation, and Vitalik Buterin, Co-founder of Ethereum, jointly attended the launch ceremony, where other participants included Tshering Tobgay, Prime Minister of Bhutan, and Jigme Namgyel Wangchuk, Crown Prince of Bhutan. Miyaguchi stated that this is the world’s first case of integrating a national-level identity system with Ethereum.  

Previously, Bhutan had been operating its national identity system on Polygon since August 2024, and before that, it used the Hyperledger Indy platform.
