I am going to push two proposals:
1\ Set up a bounty in the whole community, to improve the API capability of a single node. The best improvement win the prize,and the code can be merged into the mainnet.
2\ Improve the voting system by adding decay factor for voting. For example, the votes will expire unless updating their votes every month/year...
Anyway, the above is just simple thought, more details will be added gradually, and welcome any kind of discussion.
I would like to suggest setup a bounty for developers who built DAPP based on BTS. You may even conduct a contest to encourage developers to built different DAPP just like what Stellar did.
