General and New Releases 🎙️

Delegation is now available!

On June 23, we released Sirius, a major Mainnet update and now you can delegate your stake and earn rewards with just a few clicks on your desktop or mobile wallet!

There is no minimum amount of CCD that you need to be able to delegate to a baker pool, and you can delegate all of your CCDs, even those CCDs that are not released from the lock-up yet.

Learn how to delegate from your mobile or desktop wallet here. Read how this release benefits you here.

You can now earn commissions from your baker pool!

With our newest update, you are able to create your own baker pool others may delegate to and earn a commission from it.

Make sure to activate your baker pool. Read how to do so here.

Learn more in our FAQs.

Have you tried our improved Smart Contracts?

With the Sirius upgrade, we expanded the range of use cases supported on the Concordium and removed the limitation on state size of smart contracts. This enables use cases such as stablecoins and other fungible tokens, with many participants interacting with smart contracts.

We have also added Native cryptographic functions, so you don’t have to code them yourself.

The signature verification functions verify_ed25519_signature, verify_ecdsa_secp256k1_signature and hash functions hash_sha2_256, hash_sha3_256, and hash_keccak_256 are all added.

Building your smart contracts using these functions reduces the cost of the gas fees!

Synchronous contract calls to make it easier to build smart contracts that interact with other contracts.

Get started with smart contracts here.

A new version of the mobile wallet is available!

Concordium Mobile Wallet 3.0.0 for iOS and Android is now available and it contains the highly anticipated delegation and baking functionality.

You can now become a baker directly from your mobile device. You can also delegate stake to a baker pool or passive delegation with just a few clicks.

Testnet 3 and Testnet 4 rewards have been distributed

We have distributed the rewards to all who participated and sent their wallet addresses. We are extremely grateful to all who participated on our Testnets! Your support was critical in helping us develop a reliable Mainnet!

Thank you again for being our first Champs!

Ecosystem and community updates🤲

E-Seal your files with a simple drag and drop

With a simple drag and drop, you can now use your own Concordium account to seal a file by registering its hash on chain.

Seals are used to protect things which must not be tampered with. A seal is unique to the sealer and shows the valid execution, source, and authenticity. If you seal a file, you can prove that it was in your possession at the time of sealing.

Try it yourself here.

Concordium Name Service is around the corner!

Bictory Finance aims to release their Concordium Name Service (CNS) on July 25th! With this service, you can own your name on-chain and get a bundle of benefits, including simplified dapp logins, transactions, and even decentralised web domains.

Learn more about it in our AMA.

Amdax, VirtualHive, Northstake, Stakely and more invite you to delegate

Other Tech Updates 👨‍💻

Concordium Node V. 4.2.1 has been released for Mainnet and Testnet

Concordium Node 4.2.1 is a maintenance release, bringing performance improvements and bug fixes. The highlights are:

A significant decrease in node startup time. The exact improvements are platform dependent, but startup should be at least 6 times faster on mainnet.
A significant decrease in node memory use. On mainnet, a 4.2.1 node should use less than 50% of memory compared to 4.1.1.
Reduced CPU use of passive nodes in Windows, Mac, and Linux distributions.

Please see release notes here.
