The Tron blockchain halted creation and execution of blocks due to a “malicious contract” against a super representative on Nov. 2, according to multiple reports.
Tron uses a Delegated Proof-of-Stake (DPoS) consensus mechanism. DPoS blockchains sacrifice decentralization for throughput by centralizing certain transaction activities to majority nodes.
Tron CEO Justin Sun followed reports with a tweet thread stating that the pause in block production was caused by an attacker exploiting the latest Tron software. Updating the node’s software began block production again, Sun said.
Tron did not return questions for comment by press time.
