Hope will not be misplaced for Concord, as its $1 million bounty will not be the smallest proportional to the quantity of funds misplaced. In 2021, the Poly Community interoperability platform was hacked for $610 million. The group’s bounty provide of $500,000 was 0.08% of the full stolen. The provide was rejected, however fortunately the funds have been returned anyway.
