As an Ethereum and Steem investor, I'm always curious about two chains competition. Today I would like to talk about Ethereum's social network service, Akasha.
To prevent infinite loop attack to its network, Ethereum has a gas feature. IMHO because of it, Akasha will not be able to compete against Steemit or existing centralized SNS. Already high gas price is killing some projects.(See high gas price is killing some projects seriously.)The gas price was supposed to go down proportionally to the Ether currency price increase.
Price is somewhat dropped. But in a fixed, artificial manner. Why? This gas price has to be fixed to certain level which enough to protect its most valuable/expensive dapp. Otherwise there will be infinite ways to bribe other miners and users to include transactions. Now you have to pay fixed gas price when you post, vote, edit. People want certain features as free. I'm afraid that people will not use pay to post service. IMHO those Turing completeness support chains will suffer from similar problem.
Conclusion
Fixed gas price will be a serious problem of Akasha.
