But such a change in PoW renders\nmulti-billion-dollar of ASIC into worthless. which hurts economy so much\nand the average innocent mining users. I would propose, instead of PoW\nchange, we could change the system to the same double sha256 PoW but mix it\nwith PoS features. Such a PoW+PoS system has several advantages:\n* It protects existing multi-billion dollar investments from innocent\nmining users,\n* A malicious miner cannot launch attacks and rewrite the blockchain with\n51% or even more hashrate,\n* If we insert 4 PoS blocks between 2 PoW blocks, we'll have 2-minute block\ntime span, that solves the long confirmation time problem,\n* We'll suddenly have 5 times of block space, that solves the scaling\nproblem,\n* The PoS blocks only mine transaction fees, so the 21M cap remains,\n* With careful design, the PoW+PoS transition _might_ be able to deploy\nwith a soft fork.\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20170620/8b2e692c/attachment.html\u003e"}
