Remove references and copyright
Licensing is done at the repo level. The listed references are awkwardly incomplete (only the Python implementation was listed when we have ~10 implementations, and only the Casper paper was listed where we could add many ethresear.ch posts).

Possible aesthetic rework to get_domain
In general I dislike how domains, which should be an unobtrusive out-of-the-way thing that we don't think about much, are taking up so much space in code to express, to the point of them being the single thing preventing `bls_verify` from being expressed in one line of code. Here I reorder arguments and add a default, and make `bls_verify` a one-liner.

Not necessarily convinced that exactly this approach is the way to go, but IMO it's worth considering.

vbuterin f5c5c166af Replace custody challenge game with JABS (#812)
See also #818.

===

* Replace custody challenge game with JABS

Replace the existing proof of custody game with a new game ("Justin's Awesome Bit Sum" or JABS) that works as follows:

* The data `D` is split up into 512-byte chunks `D[0] .... D[n-1]`, and use a mix function `mix(subkey, data) -> {0,1}` (currently the first bit of the hash of `subkey+data`). We calculate `M[i] = (mix(D[0]) + ... + mix(D[i-1])) % 2`, and set the custody bit to `M[n-1]`
* Anyone can challenge by providing the full `M` where `M[n-1]` is not equal to the custody bit
* Anyone can respond to a challenge by providing a specific position in `M` along with a branch of the data where `M[i-1] ^ mix(D[i]) != M[i]`

The maximum size of data is now `2**6` epochs *  `2**6` blocks * `2**14` bytes = `2**26` bytes, so assuming 512-byte mix chunks the maximum mix size is `2**17` bits or `2**14` bytes. The average mix size is `2**8` bytes.

The 1-round custody game has been implemented. Many bugs squashed, and a bunch of polishing done. Miscellaneous known issues (~8 of them) to be resolved in separate, smaller, PRs.

Re-added some penalization in case of failure to finalize 2019-03-21 15:13:13 -05:00
vbuterin d1d1b73fb1
Simplify justification and finalization accounting logic
Much of the simplification is cosmetic. The following changes are substantive:

* Inactivity leak penalty specifically on missing the target, not both the target and the source
* Even outside of quadratic leak scenarios, slashing victims suffer offline penalties

Replace committee exponential backoff with max progress
Removes the mechanism that only rotates committees if blocks have been finalized and every shard has been crosslinked or at exponentially decreasing intervals, and replaces it with a rule that shard committees can only progress a maximum of 64 epochs at a time to preserve the invariant that maximum possible work required per epoch for a validator is O(1).

This is to prevent a spam/DoS attack where validators with zero balance get "slashed" but no validator loses any balance.

vbuterin 91a0c1ba5f Persistent committee size per slot reduced to max 128 (#734)
* Persistent committee size per slot target 128 max 256

Cuts down the cost of verifying a shard chain and aggregating signatures for a shard chain, and also makes the shard chain signatures more usable by light clients for verification as they would only need to keep track of a max 256-sized committee.
