Today we are thrilled to announce the launch of Lisk Nano 1.0.0, marking the first major release for a Lisk product. Lisk Nano 1.0.0 is supported on macOS, Windows 7/8/10 and all distributions of Linux. Lisk Nano offers greater flexibility for the end user to select their desired network or node. This means that public nodes are far more important to the network than they were before. Desktop notifications are also present in this release, making it much easier for users to know when their balance has changed.

Delegate Registration and Second Passphrase

With Lisk Nano 1.0.0, users now have the ability to register their Lisk account as a delegate.
A delegate is a special type of Lisk account. Any Lisk account can become a delegate by simply registering a delegate username within the Lisk client (and now with Lisk Nano). The registration fee is 25 LSK, however this may be subject to change in the future.
Additionally, a transactional support has been added to allow users to register second passphrase. Enabling second passphrase is the best way to keep your account secure and we highly recommend using one. Note: DO NOT misplace your first or second passphrase as this will result in losing access to your Lisk Account.

Voting Interface and Forging Center

One remarkable enhancement to Lisk Nano is the addition of the Voting Interface. This section replaces the existing web wallets functionality and enhances the features that the web wallet used to serve. The Voting Interface provides users the ability to vote for the Delegates who secure the underlying Lisk network. If you’re interested in learning more about voting, visit the voting section of the Lisk Delegate Handbook.
Also, the forging center was inspired by the Web Wallet (lisk-ui) as the primary landing page for delegates. This functionality was completely recreated using the existing web wallet as a template.

Signing and Verifying Messages

Finally, Lisk Nano offers an all new feature that allows an end user to sign and validate messages cryptographically. It can be used for escrow, validate important messages or announcements, proof of ownership and many more cases. For the more technical readers, for signing we are using the EdDSA family, specifically Ed25519.
