Dear Ubiubi18, thank you for the nice analysis and introduce ubi space. Regarding Sybil attacks on universal basic income,ubi crypto project, Taucoin is not an ubi project but requiring user effort or money to secure coins. Accumulating transation weight needs holders pay fees and compete to be packed up in next block. One part we soon put into whitepaper is miners need to pack higher transaction fee to increase own likelyhood to generate next block, which is randomness x fee in block. Therefore, holders transfer numerous coins among own addresses will have to pay attractive fees to be recogonized. These fees collected by miners will be distribute to club members according to the history transaction weight or transaction fee weight, between these two we have not decide.
I am in line with you on not doing centralized KYC and replacing pow/pos.
