Security advisories, best practices, and network health
Ethereum Classic experiences massive hashrate increase as GPU miners migrate from Ethereum following the proof-of-stake transition.
Ethereum Classic implemented ECBP-1100 (MESS) in October 2020 to defend against 51% attacks. MESS was later deprecated after hashrate grew substantially post-Merge.
Essential security guidance for Ethereum Classic users covering wallet safety, transaction verification, and scam awareness.
At block 2,500,000 on October 24, 2016, the Gas Reprice upgrade (EIP-150) was activated as an emergency response to the Shanghai DoS attacks that had been crippling the network.
In August 2020, Ethereum Classic experienced three chain reorganization attacks. The network responded with ECBP-1100 (MESS), increased confirmations, and ultimately benefited from post-Merge hashrate growth.
After the 2016 DAO fork created two chains with shared history, replay attacks became a real concern. How ETC and ETH addressed the problem.
How denial-of-service attacks target blockchain networks, the 2016 attacks on Ethereum/ETC, and the protocol-level defenses that were implemented.
Why confirmations matter on proof-of-work chains, how many are needed for different transaction sizes, and the economics of chain reorganizations.
Following 51% attacks in 2020, Ethereum Classic implemented MESS (ECBP-1100) to penalize deep chain reorganizations — and later deprecated it as hashrate grew.
The ETC community issued warnings about fraudulent websites impersonating legitimate dApps to steal user funds through phishing and malicious smart contracts.
