ASIC : GOOD thing BAD thing
- Community/user-base. If it were not for miners, a coin would never get exposure. Thus the more miners, the more exposure. A coin may have a superb technological innovation. No miners, means no adoption. Asic is slimming down that community. Bitcoin does not need that community anymore. As it has a lot of use cases and wordwide adoption It’s big enough now… Monero needs it, and therefore has an aversion to ASIC.
- Technology : As (most of) crypto is open source. There is no real “company” behind it to steer and finance its development. So it needs a community. Asic mining is slimming that community down. And hereby slowingdown the implementation of technological innovations. Hence, for example, the split of Bitcoin Blockchain. Monero is innovative and must be very flexible because it depends on its community. Hence their aversion towards ASIC. Zcash does not really need that community. Its basically Bitcoin with Zksnarks. There is, as of my knowledge, no android wallet that implements z-addresses and anonymous payments YET. You need a daemon and a blockchain on linux in order to do a zksnark payment. So,to my opinion, the viewpoint of @zooko towards ASICS is understandable. And in the long term, will be the demise of Zcash.
- Price : Asics are putting a pressure on the price. At first (when competing with GPU) they are more effective, so are ming more coins for the same electricity/investment price. Once CPU/GPU eliminated, profits are evaporating. And if there is no “real-world” implementation (like with Litecoin) or technological innovation (DASH), there is obscurity forever (sia, decred, …).
- Mee-too effect / split : In the beginning there were a lot of bitcoin-mee-toos. Few of them exist as of today. Still existing ones are mostly are asic-mined. They still exist because they added functionality to the Bitcoin protocol AND thus have real-world use cases (Dash, LTC). The PU/CPU mined ones still exist because of their ASIC aversion. Monero at first was a hard-fork split too.
- Ethics : On the other hand, there is for example Karbo, Monero, PASL, TRON that are “amateur” - initiatives that have strong ethics and “believers” and “followers” They are ASIC-aversive, and that is NOW (not in the future) their only reason of existence. This underscribes my viewpoint that, in the beginning, miners are your only user-base.
- Exchange : Exchanges became the second most profitable source of money and real-world use case of crypto. Listing on an exchange became prohibiting expensive. If your coin is not listed or not popular on an exchange and it’s starting to be ASIC-mined : farewell.
- Attacks : The fear of centralisation due to ASIC mining is real. It happened to ETN. They do not have a community an is a marketing-stunt. They have no answer to the ASIC, no technical answer. They will not stay
- Waste of energy - Pools : mining is essential a waste of energy and computing power. ASIC are the sheer prove of that. Once an algoritms changes, you’re left with a brick. If tomorrow’s coin come with a mining algorithm that really DOES something usefull, and not just competing with each other. Like for example calculating solutions to an AI-queeste, then the question of pools becoming too big, or ASIC-mining will simply cease to exist, just like as of today nobody is talking about the profession of coachman anymore. The drivers became their own coachmen.
- future : watch for algo’s that do what I came to explain in my previous point.
