Reading through our UDC security overview (lnd.im/UDCSecOv), you may have been wondering, how have we managed to make the multisig keys where the components of the compound key can be updated after the creation? (Such keys are used for the UDC supervisory board). So the regular security procedures, like security key recycling, can be executed even in blockchain environment, without affecting any previous signatures. Variable multisigs – definitely not an everyday feature in other blockchains… And now our regular Java API is enabled with the helpers for this! Check out our release 3.14.4 (lnd.im/uni3144) in Github and use it in your projects. This, and also some recent enhancements in the smart contract constraints, has lead us to even largest feature: ManagedToken reference implementation. It lets you make a mintable token where the minters can be changed after the creation, and the total minted amount is audited and logged. With this implementation, you cannot secretly mint any new amount of tokens – but if you published all the logs, you can now securely and cryptographically prove the total supply of your token. Even the “burning” operations are logged, so the total supply can both be increased and decreased in the future, and still be proven. Check out our Github for the implementation.
