According to the official NEM forum, NEM has postponed the launch of the new blockchain Catapult testnet originally scheduled for November 27. NEM official said that due to configuration problems and the correct generation of keys, several obstacles were encountered during the test, but some nodes have been deployed so far. With the change of fushicho2, the technology stack needs complex debugging, which also affects the progress of the release. In addition, the migration to the testnet requires compatibility of all supporting facilities such as wallets, browsers, REST, and SDKs. More details on this will be outlined in subsequent migration updates.
