I see SEER roadmap only ends in Q2 2018 on the website that has the purpose of "Release Third-party Developer Interfaces". Has that been done? And if everything goes according to plan, does SEER have a new roadmap to be implemented in 2019?
Yes, the third-party developer interfaces has been released. Bibi is a prediction Dapp developed on SEER, its status is now open source on github:
https://github.com/a252735364/bibiThe open source of Bibi on github is to show the developers without blockchain knowledge how to develope a Dapp on SEER.
The cost to develope a Dapp on SEER is much lower than develope a Dapp on Ethereum or other blockchains. If to develope a Dapp on Ethereum needs $200,000 budget, while to develope a Dapp on SEER, $20,000 will work, that means only 10% of the developing fees compared to other public blockchain.
The 2019 roadmap of SEER mainly focus on 3 aspects: lanuch the function of sport events crowdfunding, developer competitions and ecosystem construction of Dapps.
