Cardano 1.5 Released on Testnet: Another Step Towards Ouroboros Genesis

On March 7th Cardano released the testnet for Cardano 1.5. The testnet includes the release of Daedalus 0.13.0 with Cardano SL 3.0.0. This is the last step of the Byron development phase which will lead onto the Shelly.

What is Changing? ‘This update brings a new consensus protocol, Ouroboros BFT, which is a key step in the transition from Ouroboros Classic, the current consensus protocol running the Cardano network, to Ouroboros Genesis, the protocol for the Shelley era.’

The ultimate aim is to match proof-of-stake with the security benefits of proof-of-work. When it is released on the mainnet it will deactivate the Ouroboros Classic protocol and activate the Ouroboros BFT consensus protocol.

This will technically be a hard fork; however, they caveat this by stating that it will be a smooth transition as it is a planned upgrade and all parties of the federated system have agreed to the upgrade.

Testnet Users

In the statement they ‘strongly encourage’ all current testnet users to upgrade to Cardano 1.5 as this will help developers to test the transition before upgrading the mainnet. Users will be able to upgrade by following prompts in the Daedalus wallet when 1.5 is released on the mainnet.

Moreover, they encourage exchanges to migrate from v0 to v1 of the wallet API. Also, they should use the testnet release to test their intergration with v1 API. They caution that v0 wallet API will be removed from the 1.5 release and can no longer be used.

When Will it be Released on the Mainnet?

Cardano 1.5 is currently only on the testnet but some have speculated that it will be released onto the mainnet sometime around the end of March/beginning of ...
