I havent touched on solidity at all. for those who has been programming with solidity, i have an idea of a coin:
something related to living will/trust.
I have created traditional living will it is more thna 100+ long, extremely difficult to interpret. i dont feel comfortable leaving such document for my child and other beneficiaries.
so i thought digital will that can have following capability:
1.can specify time of distribution with big flexibility: xx percent on year 20xx, xx-1 percent on year 20xx+x, xx-2 percent on year 2022x+y.
2. can specify distribution percentage: xx percent to whom etc.,
Once times specified in #1 comes in, coin will be automatically be distributed.
3. Override capability: specify X number of persons who can override. Number of percentage of X persons to agree to override if disagreement arises.
That is surely possible.
If you want to create a new token, specifically designing such a requirement is feasible. I think even if you want to use a native token(ETH) instead of a brand-new token is also possible. The thing you need to look around is Hash Time Locked Contract or HTLC, you lock the coin on a predetermined hashtime which can be calculated around the specific date you want to redeem.
For further information, take a look at the GitHub repository that seems to implement the three things you want:
