Coinbase reports that it migrated its strike bakery Tezos (XTZ) from the United States to Ireland while experiencing just one minute of downtime on March 31.
Since the launch of its XTZ strike service in 2019, the power plant has become the largest validator in the Tezos network.
The Irish migration of Coinbase Custody’s Tezos Bakery was necessary due to the legal needs of the Swiss digital asset supplier Amun.
In 2019, Amun launched the first Tezos-based exchange-traded product on the SIX Swiss Exchange. Coinbase offers both storage and baking services to Amun. Changes in Amun’s regulatory framework reportedly required their deployment activities to take place within the European Union.
Coinbase states that it initially identified two strategies for migrating strike to Ireland.
The first was to stop the validator in the United States before deploying the Irish validator, which would keep security risks to a minimum despite an hour-long interruption.
In the second option considered, Coinbase would have started its Irish validator before stopping the process in the US, opening the exercise to significant security risks if both validators were operating at the same time.
However, in the end, the exchange decided that the best way was to disconnect the validator from the validator from its node to ‘perform an almost downtime-free migration’. The company explained:
“A Tezos validator has two main components: the baker, who produces new blocks with transactions in the digital ledger, and the approver, who votes for blocks that other validators produce […] Major Tezos validators typically produce or bake new blocks only every few minutes or hours, but they must vote or agree almost every minute. ”
After successfully unmounting and migrating the detacher for a minute from the center, Coinbase found that it voted or approved blocks from Ireland while producing new blocks in the US.
Coinbase later found a two-hour window suitable for migrating the baker – completing the migration.
