June 29, 2020 Summa founder documents vulnerabilities on the Liquid sidechain.

James Prestwich, a Bitcoin developer and founder of the blockchain interoperability service, Summa, has detailed vulnerabilities on the Bitcoin sidechain, Liquid. Prestwich alleges that 870 Bitcoin, worth approximately $8 million at the time, could have been confiscated on Thursday if two of the three operators of the sidechain’s multisig wallet had colluded, something which should have been impossible according to Liquid’s hereto assumed security properties as detailed in its documentation.
