The Tron blockchain stopped creating and running blocks due to a “bad contract” against a super rep on November 2, according to several reports.
First reported by Crypto Briefing, the smart contract blockchain stopped producing blocks at 10:00 UTC for about two hours, according to Reddit users. The event is noteworthy as it validates the centralization concerns raised against Tron, which already holds an infamous reputation in blockchain circles.
Tron uses a Delegated Proof-of-Stake (DPoS) consensus mechanism. DPoS blockchains sacrifice decentralization for throughput by centralizing some transactional activities on majority nodes.
Tron CEO Justin Sun followed up with a tweet thread stating that the pause in block production was caused by an attacker taking advantage of the latest Tron software. The node software update started producing blocks again, Sun said.
The platform’s native token, TRX, dropped 3% in 24 hours, according to CoinDesk 20.
Tron did not answer questions for comment at press time.
