May be suffering from what appears to be the first high-level hack of the year after an unknown miner overwhelmed the network with a sudden burst of hashing power. The apparent hack caused Coinbase to suspend trading in Ethereum Classic tokens today.

In a announcing the suspension, the popular wallet and exchange service said it had first detected a “deep chain reorganization” on Saturday; it has now suspended all interaction with the network. Since then, according to the blog post, “we detected 8 additional reorganizations that included double spends, totaling 88,500 ETC (~$460,000)”.

For the first time, the standard series was truly standard, with no set limit on production, and more models were available. After a small break, the Firebird series was introduced in late 2008 to carry over into 2009. The limited Reference 54 alto sax came in the dark Reference lacquer, with black pearls, and was available with or without high F#. The standard alto was available in either a Series II or Series III, with honey gold lacquer and black pearl key touches.

The exchange is currently assessing the cause of the disruption and has not yet stated when it will resume ETC trading services. A Hack By Another Name Coinbase originally said Ethereum Classic was experiencing a 51% attack but retitled the post to “deep chain reorganization” shortly afterward. Stev Lohja, the technology coordinator at new core development team, told Crypto Briefing that although the two are fundamentally the same, a “reorg” isn’t so much an attempt to control the network as it is to take temporary advantage of low hash power and double spend before hashing power returns to normal levels. Lohja suggests that it might have been a failed attempt to double spend ETC on the cryptocurrency exchange. He also said that although there would unlikely be any long-term systemic disadvantages, as the reorg will leave transactions in ‘orphaned’ blocks unconfirmed. “[A] Reorg is a phenomenon in blockchain when a miner mines ahead and the longest chain wins”, Lohja said. “The gap of blocks are orphaned.” The official Twitter account for Ethereum Classic has also stated that the recent disruption wasn’t so much a 51% attack as it was “selfish mining”. They have also speculated that the sudden burst in hashing power may have come from a new ASIC mining rig developed by Chinese company Linzhi, which has a hash rate of more than 1,400/Mh.

Regarding the recent mining events. We may have an idea of where the hashrate came from. ASIC manufacturer Linzhi confirmed testing of new 1,400/Mh ethash machines – Most likely selfish mining (Not 51% attack) – Double spends not detected (Miner dumped bocks) — Ethereum Classic (@eth_classic) Others reiterated that the network was under attack, although there is some dispute as to what kind of attack it was and whether funds had been successfully double-spent. Several mining pools have experienced orphaned blocks. A Twitter account linked to the block explorer confirmed that an attack was in progress, saying: We can confirm that there was a successful 51% attack on the Ethereum Classic () network with multiple 100+ block reorganization. We recommend all services to closely monitored the chain and significantly increase required confirmations.

— Bitfly (@etherchain_org) Although the consequences of the attack are not yet clear, it is unlikely to help what remains of the, which is already on damage control due to a lack of development funds. If a double spend was successful, ETC may well go the way of Bitcoin Gold. The author is invested in digital assets, but none mentioned in this article.
