But such a change in PoW renders multi-billion-dollar of ASIC into worthless. which hurts economy so much and the average innocent mining users. I would propose, instead of PoW change, we could change the system to the same double sha256 PoW but mix it with PoS features. Such a PoW+PoS system has several advantages: * It protects existing multi-billion dollar investments from innocent mining users, * A malicious miner cannot launch attacks and rewrite the blockchain with 51% or even more hashrate, * If we insert 4 PoS blocks between 2 PoW blocks, we'll have 2-minute block time span, that solves the long confirmation time problem, * We'll suddenly have 5 times of block space, that solves the scaling problem, * The PoS blocks only mine transaction fees, so the 21M cap remains, * With careful design, the PoW+PoS transition _might_ be able to deploy with a soft fork. -------------- next part -------------- An HTML attachment was scrubbed...
