Hardened Eth 1.0 voting strategy (#1218) 2019-06-28 14:43:44 +01:00
vbuterin c764202a57 Slashing penalty calculation change (#1217) 
If the exit queue is very long, then a validator may take many months to exit. With the code as currently written, however, self-slashing is a potentially lucrative route to get one's money out faster, because one can exit in 36 days.

This PR changes it so that slashing can only extend your withdrawal time, not contract it. Also, instead of the slashed balances used to calculate one's slashing penalty being those in `[withdrawal - 54 days ... withdrawal - 18 days]`, we now run the penalization algorithm once every 36 days that a validator is slashed but not withdrawn, so that it covers the 36-day period where the validator was actually slashed.  It also moves the minimum slashing penalty to the `slash_validator` function so that it is only applied once.

We also simplify the `slashed_balances` logic to be per-epoch.

Diederik Loerakker d587c4fe61 Critical fix: introduce back total-value check (#1220) 
This was dropped in a376b6607f, as improvement in dust checking.
Now that dust-checking is done, we still need to check if the sender has the minimum value, as decrease balance just clips to 0.
See be86f966f8 for older dust-creation problem work around, which was dropped in the above.

The bug enabled you to transfer your full balance to someone else, and pay the same amount in fee, possibly to a puppet proposer to collect back funds.
Effectively enabling printing of money. Silly bug, good to fix and introduce tests for.

Clarify comment on phase 0 transfers 
The comment seems to imply conjunction over each case, but the code implies disjunction; at the very least it is ambiguous.

This PR makes the comment less ambiguous.
