New block production on the Injective (INJ) mainnet has stopped, prompting a cryptocurrency community analysis to consider whether an exploit attack caused the halt. Moneystack, a crypto-focused Telegram channel, said on-chain data suggests that about $2.79 million in cryptocurrency appears to have been stolen. An on-chain message posted on Etherscan calls for negotiations with the attacker, while the Injective team had not yet issued an announcement. A mainnet is a blockchain's live production network, so halted block production can prevent new transactions from being confirmed until the issue is resolved.
