Year is an aggregate wealth management platform that supports a variety of defi protocols. It will automatically move positions between protocols to help depositors obtain the highest wealth management income. The platform aggregates compound, dydx, AAVE and DdeX agreements. When users deposit, the platform will automatically allocate funds to the agreements with the highest income at present. Then, year will give the user a proof of interest called ytoken, and the user can take out the token and corresponding income that he originally deposited through ytoken. Yfi will stop mining on July 26. In order to ensure that liquidity is not large enough to withdraw from mining, community governance yip-8 has proposed to halve the weekly additional issuance of each mine pool. Although the proposal received more than 80% support, it was invalid because the total vote rate did not meet the minimum requirement of 33%. In order to ensure that Andre's genius idea and system are not controlled by the early whale account, the yfi project is forked, code named yfii. Yfii adopts a 50% additional issuance mechanism similar to bitcoin to ensure that tokens are more fairly distributed to community members. There are 60000 yfii in total, 20000 for each of the three pools, 10000 for each pool in the initial state, and the output will be halved every 7 days. According to the share of liquidity provided by defi users for each pool, yfii will be distributed in the next 10 weeks.
