Incorrect evidence parameter documentation

[eccentricexit]

The docs and the IEvidence contract display an incorrect parameter documentation for the Evidence event.

* @param _evidence A URI to the evidence JSON file whose name should be its keccak256 hash followed by .json.

:

* @param _evidence A URI to the evidence JSON file whose name should be its keccak256 hash followed by .json.

The _evidence parameter should be its multihash without file extension , not its keccak256 hash followed by the extension. See ethereum/EIPs#1497.

It is acceptable to have a custom name + .json extension if the URI points to a content-addressed storage (and therefore uses multihash in the link) like as ipfs, such that the full URI looks like (for example):

• ipfs://QmUQMJbfiQYX7k6SWt8xMpR7g4vwtAYY1BTeJ8UY8JWRs9/evidence.json
• bzz://1e0e21894d731271e50ea2cecf60801fdc8d0b23ae33b9e808e5789346e3355e/evidence.json
• /ipfs/QmUQMJbfiQYX7k6SWt8xMpR7g4vwtAYY1BTeJ8UY8JWRs9/evidence.json

The doc should just point to the evidence standard.

Do we support bzz? None of the applications implement anything except IPFS.

Updated to IPFS path to evidence, example: '/ipfs/Qmarwkf7C9RuzDEJNnarT3WZ7kem5bk8DZAzx78acJjMFH/evidence.json'. Closing. Reopen if you think it's not good.
