Concord Exploited in Unauthorized Mint of 4 Billion ONE (Supply: X)
Billions of ONE Reportedly Minted
On-chain analyst Juiceberg reported that roughly 4 billion ONE had been created by way of empty blocks on the Concord community. If confirmed, the issuance can be equal to greater than one-quarter of the token’s beforehand circulating provide.
Concord has not independently confirmed the 4 billion determine or disclosed the vulnerability that enabled the unauthorized mint. As a substitute, the challenge stated it was working to forestall additional token creation and decide find out how to deal with the tokens that had already been generated.

Such a transfer might doubtlessly remove unauthorized tokens that stay on the community, however it might additionally danger reversing professional transactions made in the course of the affected interval.
That creates a troublesome selection for Concord. Whereas a rollback will be an efficient emergency response, blockchain immutability is a basic precept of decentralized networks. Reversing transactions might subsequently create further controversy amongst customers and builders.
