According to CoinMeta, the privacy public chain Iron Fish has announced the termination of all remaining support for its network. The team has confirmed that there is an inflation vulnerability in the Iron Fish blockchain, which stems from the calculation logic of nullifier in the code implementation of Merkle at the beginning of 2019. This vulnerability allows attackers to spend tokens repeatedly and transfer assets out via the Chainport cross-chain bridge. A fix patch has been submitted for Iron Fish, along with a review of the issue, and subsequently, the code repository will be closed and archived.
