Architecture

Flexible approval structures

The approval policy can be different according to the amount, the asset type and even the time in the day or the week. Additionally, participants in the approval policy can be inside employees, systems (e.g. AML, KYC), outside customers or trustees, human and/or machines, servers or mobile devices.

Unlimited quorum size

A customer can define any quorum-based approval scheme well beyond the default multi-sig, 2 out of 3 policy, easily extending to more advanced schemes such as 5 out of 8. No need for complicated scripting to create such schemes, just a click of a button.

Easy to replace approvers

Replacing an approver is as easy as a click of a button. No need for extra development work.

Simple and efficient

The ledger gets only one signature created using the key shares of the different approving-parties. Key shares are refreshed constantly and never exist in complete form. Not in use and not even in creation.

Ledger and asset agnostic

As the ledger gets only one signature, there is no need in using the multi-sig mechanisms of each ledger, which eliminates significant development/scripting effort needed to support new assets and currencies.
