Bitcoin BCH Hash War Will be Decided by Sustained - Not Temporary, Rented - Hash Power - Seite 2

Bitcoin SV is the new full node implementation for Bitcoin Cash that seeks to restore the original "Satoshi Vision" for Bitcoin and allow it to massively scale. For the November 15 upgrade, Bitcoin SV's feature set is not compatible with that of competing client Bitcoin ABC. When there is a disagreement between rule sets, the original Bitcoin white paper described the "Nakamoto consensus" method for miners to vote with their computing power (1 CPU = 1 vote) to enforce any rules: "The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it."

The current hash war is the world's first test of Nakamoto consensus. After the November 15 upgrade, Bitcoin ABC appeared to temporarily lead with a higher portion of the BCH network's total hash power. But ABC's perceived first-day advantage comes from a sudden burst of hash presumably rented from the Bitcoin Core (BTC) network to move over to BCH. By November 14, the day before the hard fork, Bitcoin SV's support consistently grew for weeks and dominated with a clear 72-78% lead over ABC (18-22%):  

Bitcoin ABC even dropped to tying for 3^rd place with Bitcoin Unlimited, another implementation which is compatible (as a configurable option) with both Bitcoin SV and Bitcoin ABC rule sets.

Yet suddenly on the November 15 upgrade date, a huge wave of hash magically came to support Bitcoin ABC. This came from Bitcoin.com's pool which announced it was boosting its BCH hash for only 24 hours, by moving customer hash from the BTC chain. In addition, Bitcoin ABC is receiving more support from "rented" or subsidized from BTC mining pools controlled by (Antpool.com, BTC.com, ViaBTC) or friendly (BTC.top) to Bitmain. To obtain rented hash, Bitmain must pay to subsidize the difference in lower revenue miners receive on the BCH chain when total hash rate grows, compared to mining on the more profitable BTC network. BTC.top's CEO Jiang Zhuoer estimates this can cost over 100 million yuan or USD $14 million per day. The rented hash supporting Bitcoin ABC is temporary, and will leave the BCH network when not subsidized. This is a losing proposition for Bitmain; each day a hash war continues, Bitmain must pay millions of dollars to give Bitcoin ABC an artificial advantage. But when Bitmain can no longer afford to pay for it, the rented hash will leave BCH and Bitcoin SV will again dominate by virtue of its long-term, sustained hash support.
