been reading through the Bhutan NDI implementation notes this morning and honestly the platform migration history is the part nobody seems to talk about 😂
750,000 citizens enrolled.
world's first national SSI system
genuinely impressive
and in the span of roughly two years the underlying chain moved from Hyperledger Indy to Polygon, then Polygon to Ethereum with a target of Q1 2026.
two migrations. live national infrastructure. real enrolled citizens.
here is what i cant stop thinking like i can't stop thinking about my recent loss in PIPPIN and POWER
every time the platform moves, the credentials that were issued on the previous chain dont automatically follow. they were signed against the old chain's trust registry. verifiers checking those credentials are checking against infrastructure that the deployment has already moved away from.
reissuing credentials at national scale means reaching every enrolled citizen, getting them to accept updated credentials into their wallets, and hoping the transition window doesnt leave anyone in a gap where their old credential is no longer verifiable but the new one hasnt arrived yet.
the docs frame the migrations as demonstrating flexibility. and technically they do. but flexibility at the infrastructure level and continuity at the citizen level are two different things.
honestly dont know if the willingness to migrate platforms shows healthy pragmatism about choosing better infrastructure or reveals a credential continuity risk that gets harder to manage every time the chain underneath 750,000 enrolled citizens changes?? 🤔
