Version 1.2 of Cardano's blockchain was released to its main net. This release introduces Daedalus 0.10.0, a new version of Cardano's wallet software, and Cardano SL 1.2.0, a new version of Cardano's blockchain protocol.
This release brings a new basic blockchain feature to Cardano, paper wallets. Paper wallets contain a 27-weord recovery phrase, of which the first 18 words are printed automatically on the certificate and the remaining 9 words the user writes by hand. The release also improves the wallet API and the wallet's backend performance.
