Here goes another chapter of ASIC wars. This time, Sia is under attack and is striking back with the v1.3.6 hardfork. This hardfork will reset Sia’s Proof-of-Work function. This will make ASICs by Bitmain and Innosilicon useless.

The whole story started with the Bitmain that announced their ASIC miner for Sia network just 10 days before shipping. That was the announcement that almost caused the civil war in Sia community. Why?

In june 2017, we announced that sia would be pursuing asics, and that nebulous (parent company of sia) would be spinning up a new subsidiary to manufacture asics for sia. the project gained traction, and long time members of the sia community collectively contributed millions of dollars to pursue asics.

So, it was clearly the attack of Obelisk by Bitmain.

By resetting the Proof-of-Work function, Sia developers won’t make the whole network ASIC resistant (as Monero did by implementing Lithium Luna fork).

It seems that the Bitmain will lose some money.

some say, it takes around $5-8 bil for the development only
just add the production costs of the ASIC batch itself
