renFIL (RENFIL) is a one for one representation of FIL on Ethereum via RenVM.

RenVM implements universal interoperability using the tokenised representation model. However, it introduces several advances that aim to solve many of the technical and economic problems in existing models.

RenVM was created to replace the role of the trusted custodian with a decentralised custodian. This decentralised custodian is implemented using the RZL MPC algorithm, which can generate and manage ECDSA private keys without exposing them (not even to the machines that power RenVM). This improves on WFIL by removing the need to trust a centralised custodian.
