Ironblocks’ ‘Venn’ Network Aims to Keep Malicious Transactions From Ever Hitting Blockchains

Venn is the latest attempt to address crypto’s ever-present crime problem. In any given week, projects big and small lose six-figure sums or more to fraud, theft, economic attacks and other costly capers that drain their customers’ crypto. All these transactions happen on the blockchain, where they’re irreversible; there’s no rewind button to move stolen money back into a victim account.
