Rumors of a new ASIC mining rig from Bitmain have driven Ethereum prices well below their one-week high of $585. An ASIC - or Application-specific integrated circuit - in the cryptocurrency world is a chip that designers create for the specific purpose of mining a single currency. Early Bitcoin ASICs, for example, drove adoption up and then, in some eyes, centralized Bitcoin mining in a few hands, thereby thwarting the decentralized ethos of die-hard cryptocurrency fans.
According to a CNBC report, analyst Christopher Rolland visited China where he unearthed rumors of a new ASIC chip dedicated to Ethereum mining.
"During our travels through Asia last week, we confirmed that Bitmain has already developed an ASIC [application-specific integrated circuit] for mining Ethereum, and is readying the supply chain for shipments in 2Q18," analyst Christopher Rolland wrote in a note to clients Monday. "While Bitmain is likely to be the largest ASIC vendor (currently 70-80% of Bitcoin mining ASICs) and the first to market with this product, we have learned of at least three other companies working on Ethereum ASICs, all at various stages of development."
Historically users have mined Ethereum using GPUs which, in turn, led to the unavailability of GPUs for gaming and graphics. However, an ASIC would change the mining equation entirely, resulting in a certain amount of centralization as big players - including Bitmain - created higher barrier to entry for casual miners.
