Ethereum Classic suffered a 51% assault within the early hours of August 1st.
A weblog submit from the ETC Cooperative stated attackers flooded the community with offline mined blocks. As a outcome, the community was unable to course of the amount of transactions, resulting in a reorganization of the chain and cut up between nodes.
“Miner 0x75d1e5477f1fdaad6e0e3d433ab69b08c482f14e launched round 12 hours price of offline mined blocks resulting in a significant reorg. OpenEthereum nodes had been unable to deal with that giant a reorg, resulting in a sequence cut up with OpenEthereum nodes on one facet and Core-Geth, Multi-Geth and Hyperledger Besu nodes on the opposite.”
At current, investigations are nonetheless on-going as regards to the total extent of the harm triggered.
So far, these strains of investigation haven’t turned up any proof of double-spending.
In response and as a precautionary measure, some exchanges, together with Poloniex, have suspended ETC deposits and withdrawals.
Ethereum Classic Core Developer, Stevan Lohja, went on to say an unidentified bug was the reason for the chain cut up on the level of community flooding.
Lohja really helpful node operators operating OpenEthereum, and Multi-Geth nodes migrate instantly to both Core-Geth or Hyperledger Besu.
Despite the upheaval, he sought to reassure stakeholders that it’s enterprise as traditional.
“The majority chain is working as regular. The main miners unintentionally mining the inaccurate chain are migrating to Core Geth in addition to different ETC service suppliers.”
Ethereum Classic Has Previously Been 51% Attacked
Ethereum Classic was beforehand 51% attacked, again in January 2019.
Although the total extent of the present assault is unknown, the one in January 2019 was labeled by Coinbase as a “deep reorganization,” with confirmed doubled spends totaling 219,500 ETC (or $1.1 million on the time).
“This known as a “chain reorganization,” or “reorg” for brief. All reorgs have a “depth,” which is the variety of blocks that had been changed, and a “size,” which is the variety of new blocks that did the changing.”
Back then, the incident triggered discussions over the viability and safety of proof-of-work (PoW) methods going ahead.
As the 2 most outstanding PoW protocols within the house, some even predicted the demise of Bitcoin and Ethereum.
Confusion from buyers noticed each Ethereum Classic and Ethereum expertise a sell-off because of the assault on Ethereum Classic.
Matti Greenspan was eager to emphasize that Ethereum Classic and Ethereum are distinctly separate entities. What’s extra, arguing the case for PoW, he stated:
“The motive is that Ethereum has a hashrate of about 20 instances that of Ethereum Classic. So, whereas it could be attainable to briefly get sufficient hashrate to regulate 51% of ETC’s community, it could be virtually implausible to have an effect on ETH on this means.”
The weekend assault noticed Ethereum Classic undergo a sell-off, closing 9% down on the day.
However, worth motion printed a Daul Maul wick. It prolonged as excessive as $8.30 and as little as $6.50, to shut the day at $7.18.

Considering that is the second 51% assault to happen in lower than two years, buyers are asking concerning the measures applied following the primary assault.
Or is that this an inevitability for all PoW protocols that lack the hashing energy of Ethereum and Bitcoin?
