After 2 years of intensive scientific research and development, we are proud to announce our First Public Testnet.

The Testnet has been released on Thursday, April 2, 2020, at 01:00 PM GMT.

Please read our Release notes here.

Going live

Our approach and our architecture are two of the most of the significant steps toward building an applicable and scalable regulatory-compliant financial ecosystem designed for enterprise.

The Blockchain industry is overcrowded with hypotheses, beliefs, and sometimes utopic approaches but under-saturated with practical projects and with Enterprise-centric projects in particular.

Concordium has always been determined to enable enterprises to create and deploy private and compliant-ready solutions. So today, we are excited to announce the launch of Concordium’s Public Testnet.

We know that the deployment of this kind of novel approach is a grinding and iterative process.

We are not forking an existing Blockchain protocol, instead, we are designing a brand new protocol with the help of some of the most talented academic researchers and developers.

As we move along our roadmap, we know we might face some unforeseen challenges together. Concordium’s development and deployment is about transparency and openness. We always will communicate when it comes to addressing problems and issues.

Parameters

Epoch is set to 1 hour,

Slot time is set to 1second

Yearly inflation is set to 2%

Difficulty parameter is set to give a Block time of approximately 25 second

Tokens are minted every slot (determined by inflation) and 50% of the unused minted tokens are given as Block Reward (Block Reward percentage is chosen arbitrarily for the Testnet purpose only)

Testnet Tokens Distribution

For the purpose of this Testnet, we are issuing 101,000,000 Testnet GTU which are going to be distributed as follows:

70,000,000 Testnet GTU are going to 20 Bakers Accounts, meaning 3,500,000 Testnet GTU per Account

20,000,000 Testnet GTU are meant for Delegation and will be distributed between 4 Delegation Accounts, meaning 5,000,000 Testnet GTU each

10,000,000 Testnet GTU are going to our Testnet GTU Drop Account

Last million of Testnet GTU goes to a special Controler Account

Please remind that Testnet GTU have no economic value and are provided for the purpose of testing only.
