, et al.
Issue: SPV proof
Redeem: Operators need to submit the proof of minting, or get punished (their deposits get slashed).
No on-chain validation of superblocks. TrueBit-style off-chain validation.
Require two Merkle proofs (proofs of inclusions of transactions / blocks)
Issue: SPV proof
If the operator walk off with “locked” DOGE, any WOW Hodler can then burn WOW in exchange for his ETH collateral. (Described in the section 4.8 of the next paper)
