Description
Suppose that N players share cryptocurrency using an M-out-of-N multisig scheme. If N− M+ 1 players disappear, the remaining ones have a problem: They’ve permanently lost their funds.
We introduce Paralysis Proofs. A Paralysis Proof is a proof that players cannot act in concert, eg, some players have become unavailable. Paralysis Proofs can support the construction of a Paralysis Proof System, which helps maintain resource availability by updating (eg, downgrading) the resource’s access structure when critical players, ie, key-share holders, become unavailable.
