THELOGICALINDIAN - In beforehand February the aggregation abaft Ethereum band 2 ascent band-aid Optimism accustomed chat on a analytical bug that could acquiesce a bad amateur to actualize ETH on the arrangement The bug was allotment of the solutions Geth angle and was apparent by Jay saurik Freeman Head of Technology at Orchid Protocol

A bad amateur could accept leveraged the vulnerability on this Ethereum band 2 solutions via the SELFDESTRUCT opcode on a arrangement that captivated funds in the basal cryptocurrency, according to an official post. However, the bug was anchored after it anytime actuality exploited.
The aggregation abaft Optimism conduced a alternation history and apparent the bug was alone triggered once, 40 canicule afore actuality discovered, accidentally by an Etherscan employee. However, the being didn’t accomplish ETH, per the analysis conducted by Freeman. The aggregation added:
Optimism forks were additionally alerted on the vulnerability and, as the aggregation said, all activated the fix. In that sense, they alarm on anybody active a replica of their software to amend to l2geth adaptation 0.5.11 or accident un-synchronization with the blow of the network.
Freeman will accept the best bounty, estimated at $2 million, for his addition to the Ethereum ascent solution. The aggregation abaft Optimism thanked him for “helping to accumulate Optimism safe”. They added the afterward on the new challenges that a growing activity faces:
How To Attack An Ethereum Scaling Solution
Freeman published a abundant address on his discoveries, abacus that the additional band band-aid was opened to an advance via their client, OVM 2.0 a angle of go-Ethereum referred to as l2geth. The Orchid Protocol, as he said, is a additional band ascent solution. So, his acquaintance was invaluable back advertent the vulnerability of Optimism.
Freeman alleged the bug he apparent “Unbridle Optimism” and claimed it originated on the basic apparatus active acute affairs on the Optimism. By exploring it, a bad amateur could aftermath ETH on “the far ancillary of the bridge” abutting the L1, Ethereum, and its additional layer. He wrote in his report:
The calamity ability accept advance to the absolute Ethereum ecosystem as a bad amateur could accept been able to go into decentralized protocols application Optimism and “mess with their economies”, the address said. Thus, Freeman alleged it an “economic griefing attack” with the abeyant to attempt the “entire ledger”.
