The Research & Innovation team is working on a design to provide fast peg-ins and peg-outs through untrusted third parties.
Currently, peg-ins require mining 100 bitcoin blocks due to security reasons. The main idea of the fast bridge is to reduce this time by allowing community members to register as “liquidity providers” and provide RBTC for other users in advance. After 100 block confirmations, the bridge contract then reimburses the liquidity provider. This process can significantly reduce peg-in time because liquidity providers may not require as many block confirmations as the bridge to deliver the RBTC.
In the worst case scenario (i.e., the liquidity provider does not deliver), the process falls back to the traditional peg-in through the bridge. This means that users are never at risk of losing funds.
