Fix delay-based attestation inclusion reward
Modify the delay-based reward function from the current `r = (65-d)/64` to `r = 1/d`.

Rationale is that in the normal case delay is close to 1, so we want a larger incentive to get included more quickly to encourage stability of the fork choice. Particularly, in the status quo if you know that you will be a proposer <4 slots in the future, you can maximize earnings by delaying inclusion of your attestation until you can include it yourself and get the proposer reward; this adjustment fixes this in the normal case.

cleanups to get_seed
1) Put `domain_type` and `epoch` upfront. This pattern can be reused for signature domains.
2) Change `int_to_bytes(epoch, length=32)` to `int_to_bytes(epoch, length=8)` to match `uint64` length.

Deposit contract fixes (#1362) 2019-09-03 18:59:18 +01:00
Justin 3ef24870d6
Changes as per today's discussion
1) Make `ShardBlock` and `ShardState` flat containers (as opposed to plain containers)
2) Make Gwei deltas `int64` (as opposed `uint64`)
3) Make `older_committee_deltas` a `Vector` (as opposed to `List`)
4) Apply size fee on block body only (as opposed to block header and body)
5) Enshrine minimum "extra" block body fee for proposers (reusing `PROPOSER_REWARD_QUOTIENT`)
6) Fix bugs reported by @terencechain and @hwwhww 👍
