Concordium’s highly-anticipated release follows three years of scientific research and development, and testing.

Concordium Foundation has launched the initial version of the Concordium Blockchain and its MVP on June 9th 2021.

In the following lines, we will discuss the nature of the release, the agenda and the instructions for GTU buyers to claim their tokens. We have also added a Q&A section to ease the comprehension.

The initial phase covers code logic, security, and operational deployment.

  • Token Distribution and first Listing Event — July 26th 2021

First lockup releases as per our Release schedule.

Genesis Block

Concordium Genesis Block was created on June 1st 2021 but the Concordium Blockchain started, today, on June 9th, 2021 at 8:00 AM CET.

Initial Phase

After launch, Concordium will retain control of the network during the initial phase to secure and stabilize it and conduct further performance testing.

During this initial stage, Concordium Foundation will run nodes that will stress test the network in real conditions. During this phase, no external nodes will be running.

The rewards that will be produced by the Concordium Foundation will be equally distributed during the Distribution event between all GTU presale buyers.

GTU buyers are to proceed to some important action items during the Initial Phase as described in the Instructions section.

This period will also allow Concordium to execute critical logic, security audits, and operational deployment to calibrate the final aspects of the network.


Users who purchased GTU tokens at the presale stage can claim them. In order to do this, you have to complete a couple of actions. In this guide, we will describe how to claim GTU tokens using Concordium Reference wallets.

We strongly recommend to use the Concordium Desktop Wallet which requires users to have a Ledger Nano S at the reach of a hand.

In order to claim tokens you will have to follow the instructions:

  1. Download a Concordium Wallet
  2. Create an Identity and an initial account
  3. Create a additional account (not mandatory but recommended)
  4. Share the address of this new account with the Concordium Team

Guides and tutorials

Create an identity and an account using the Concordium Desktop Wallet

The full tutorial is to be found here. Once the Ledger hardware has been initialized the following steps must be executed:

  • Go to Accounts. A message is displayed saying you don’t have an identity or an initial account yet. Select Request new. If you’ve been using another computer, and you already have an existing account, you can select Import existing.
  • Enter a name for your identity, and then enter a name for your initial account. Select Continue.
  • Select an identity provider. Currently, Notabene is the only one available.
  • Connect your Ledger hardware wallet if you haven’t done so already and enter your pin code on the Ledger. Press the buttons above the up and down arrows to choose a digit, and then press both buttons to select the digit. When you’ve entered the PIN, press both buttons, and when it says Concordium press both buttons again. The Ledger says Concordium is ready.
  • In the Desktop Wallet select Submit, when it says Ledger Nano S is ready.
  • Press both buttons to confirm the export of the following on the Ledger: Export PRF key, Export IdCredSec and Public-key
  • Press the right button to review the transaction on the Ledger. Verify that the following information on Ledger is identical to the information in the Desktop Wallet: Identity Credentials Public (IdCredPub), Registration ID (RegId), Verification Key, Threshold.
  • The Ledger says Sign transaction. Press both buttons to sign the transaction.
  • In the Desktop Wallet, enter the identity verification information and select Submit. This information will vary depending on the identity provider. The identity provider submits the identity to the blockchain. When the initial account is created in a finalized block on the blockchain, the identity provider confirms the identity, and after confirmation, a green check mark is displayed next to the Concordium logo on the identity.
  • Select Finished. When you’ve created more accounts, you can recognize your initial account by the text (identity) next to the name.


When you’ve created your identity and account, we strongly recommend that you make an export of all accounts, ID’s and addresses in the Desktop Wallet. This way, you’ll have a backup in case the database is damaged.

Create an identity and an account using the Concordium Mobile Wallet

The full tutorial is to be found here.

  • You will get a choice between making a new initial account and identity, or importing an already existing set. Assuming this is the first time you are using Concordium Mobile Wallet, you can choose “I want to create my initial account to continue.”
  • On the next screen you will see a description of what the initial account is and the three steps you have to finish to get it, along with your identity. In short, the initial account is an account submitted to the chain by the identity provider of your choice, which means they will know that you are the owner of the account. Later you will be able to submit accounts to the chain by yourself, which means the owner of these accounts will be only known by you.
  • The three steps mentioned above are: Naming of your initial account | Naming your identity | Requesting the initial account and identity from an Identity Provider of your choice
  • You will meet the first step on the next page, which prompts you to enter a name for your initial account. Pressing continue will take you to the next page, on which you have to name your identity. Both of these names will only be known by yourself, so you can name them more or less whatever you want (There are a few constraints on what letters and signs you can use).

In the examples below, we choose to call our initial account Example Account 1 and our identity Example Identity 1. As mentioned, you can choose whichever names you want.

  • By pressing Continue to identity providers, you will be taken to a page where you have to choose between identity providers. An identity provider is an external third party who will verify who you are, before returning an identity object to be used for creating accounts on the chain. For now Notabene is the only option, but more might be added later.
  • By pressing an identity provider button, you will be taken to the provider’s identity issuance flow. It will look similar to the one below.
  • After finishing the identity issuance flow, you will be met with the following screen. It will show you an overview of your identity and the initial account.
  • Depending on the identity provider you have chosen, the layout of the identity card might differ slightly. You can see that Example Account 1 is held by the identity Example Identity 1. The account created during this process will be marked with (Initial) in the app, so you know which account is the initial account submitted to the chain by the identity provider.
  • By pressing Finish you will be taken to the Accounts screen. On this screen, you will be able to see your newly created initial account. It might be showing a Pending icon, which means the identity provider is still working on submitting and creating your initial account and identity. You can also navigate to the Identities screen by clicking on Identities at the bottom of the display. On this screen you can see your newly created identity, which might also still be pending in case the identity provider has not finished it yet. All you have to do now is to wait for them to finish.

Communicate your Public Address

In order for Concordium to arrange the transfer of your GTU to your account, Concordium will request you to inform us of your Concordium account number (i.e. your GTU Public Address) to where the GTU shall be transferred.

In the week starting Monday the 14th of June 2021, you will receive a separate email with an attached personal letter with specific instructions regarding the process whereby Concordium shall be informed of your account number to where the GTU shall be transferred.

As part of this process, Concordium will verify that we have the correct email address and that the communication regarding your instruction comes from you.


Please observe that you should not provide any information about your account number until you receive a request from Concordium about the communication of the account number.

When might I expect to get the tokens I’ve purchased in a private sale?

Tokens purchased during the private sale events will be distributed in the buyer’s wallet before the first listing. From Genesis until first listing, buyers will have to complete a set of actions to claim their tokens as seen above.

We estimate that this process will take around one month to complete and the first GTU will reach buyers’ wallets no later than July 26th 2021.

What do I need to do to get my tokens?

You need to download one of our wallets, to create an initial account and deploy an identity. We strongly recommend creating an additional account and using it to claim your tokens. Then, you need to share the public address of your account with our team as described above.

Do I need to proceed to another KYC?

Yes, every single user of Concordium will have to link an identity object created on Concordium to a Concordim Account. To proceed please follow the instructions above. Then share with our team your public address.

What will the Concordium Team do during the Initial Phase?

We will mainly proceed to a lot of security testing and we will verify all GTU buyers’ newly created accounts to match our records.

In other words, we will conduct security tests and will proceed to the preparation phase when it comes to token distribution.

Why has Concordium not hard-coded the allocations in the Genesis Block?

Simply because one of our specificities is our ID feature. To use the network and thus to get your tokens, you must create an identity object that will be linked to your Concordium Account.

Will my locked tokens appear in my wallet?

Yes they will. You will be able to see your released tokens and your locked tokens.

Can I use my locked tokens to bake?

Yes you can and you are invited to do so.

Is staking available at launch?

If you run your own baker, you’ll be able to stake GTU, once the tokens are distributed.

Delegation will be released at a later stage.

When to expect the first listing?

Right after the Initial Phase, around July 26th 2021.
