Collecting confirmations for the Binance Chain is made in form of mutlisig wallet - the validator's confirmation is participation in the transaction signature gneration with usage of Threshold Signature Scheme (TSS) implemented for ECDSA by [KZen Research team](https://github.com/KZen-networks/multi-party-ecdsa).
At this version the tool for TSS is used as is. It is assumed that later part of TSS orchestration will be moved to the orchestration contract. So far, the orchestration contract is used as a database to keep data required by TSS parties during the signature generation.
