Why no blockchain yet?

A shared ledger is part of Tamga Network's goal. But today the network does not run on a blockchain. That is not a gap; it is a deliberate order of steps. The reason is in the last line of the previous page: a chain's value comes from several independent parties.

A ledger needs more than one hand

Today the network has one operator: Tamga, acting provisionally on behalf of the states. On a chain run by a single operator, the same party produces and approves the blocks. Such a chain adds cost and complexity but no trust. To be honest, in that situation a chain is just a slower database.

What we use today

Instead we use the model Europe uses for its own trusted lists: signed, versioned lists chained to each other. As we saw on the earlier pages, every version carries the digest of the previous one, history is never deleted, and a public anchor log is updated every hour. Anyone can detect a list that was rolled back or quietly changed.

There is a limit, and we say it plainly: today the last link of trust is one operator's signature. The public log, transparency and audits deter misuse, but they do not make it impossible. The chain will come to spread that last link across several hands.

When does the chain come?

The rule is simple: a permissioned shared ledger starts once at least two independent operators, meaning at least one party legally and operationally separate from Tamga, join in writing. That party can be a state body or an institution the state authorises. As more states join, the number of operators grows, and so does the ledger's assurance.

The switch will affect no one

The network was designed for this switch from the start. Institution and credential-type identifiers are already computed exactly as on the chain. The list history can be replayed into the ledger, and tests check that both give the same answers. Wallets, verifiers and credentials look at trust through a single interface; when the ledger replaces the lists, nothing changes for them.

One rule does not change either: no personal data, credential or credential digest is written to the ledger. However strong the chain, people's information does not live there.
