The MOAC Story Part X: Attempting to Improve POW’s Transaction Processing Speed

In recent years, attempts to improve the processing speed of POW transactions (mostly reflected in POS and DPOS) have moved away from hash collision mining and towards monitoring who has the largest number of native cryptocurrency and a longer time. This approach can probably increase processing speed to over several thousand, about the 2,000–5,000/second level, without sacrificing the advantages of globalization. However, POS and DPOS have shortcomings of their own. POW has been validated by 7 years of implementation when compared with BFT. POS has yet to be tested in large-scale networks.

Ethereum’s new development direction, a POS solution named Casper, appears to need at least 2 years before being fully implemented. And because the transition from POW to POS will involve current community interests, the most likely compromise will be the creation of a two-headed POW+POS. This will make the problem more complicated and make it impossible to solve Ethereum’s speed problem.
