- [Not in A/V] ERC-20 Token Standard Finalization [Fabian, Nick, or Hudson]
- Metropolis updates/EIPs.
- a. Details and implementations of EIPs.
- [0:00] "Agreeing on gas costs for MODEXP, ECADD, ECMUL, ECPAIRING. For MODEXP specifically, are we going to modify it to somehow incorporate bit length or not?" [Vitalik]
- [9:16] Concerns around the REVERT opcode introducing an economic change that may break things and revisiting cost/benefit analysis of the opcode. [Vitalik]
- [16:56] "Regarding EIP 96: should the gas price of
BLOCKHASHalready change from the beginning of the Metropolis, or from the block where the behavior ofBLOCKHASHchanges?" More info: https://github.com/ethereum/EIPs/pull/210/files#r117211219 [Yoichi] - [24:34] "Regarding EIP96 (BLOCKHASH contract): should the blockhash-maintainance call at the beginning of each block increment the nonce of
SYSTEM_ACCOUNT? https://github.com/ethereum/EIPs/pull/210/files#r117260179" [Yoichi] - [26:14] "Regarding EIP98 (med state removal): this should start at (inclusive) METROPOLIS_FORK_BLKNUM instead of one block after that (as written in the EIP). Pointed out by @gumb0 ethereum/EIPs#98 (comment)" [Yoichi]
- [26:50] "Regarding EIP 211 (RETURNDATACOPY): the behavior of reading out-of-bounds from the returndata buffer is under discussion." [Yoichi]
- b. Updates to testing.
- [47:21] c. Any "subtleties" we need to work out.
- [50:52] d. Review time estimate for testing/release.
- [1:09:03] [Time permitting] "If we have time (no high priority), I would like to get some feedback about adding functionality that allows dapps to be notified whenever a certain address was touched by a transaction (including internal calls). This information does not necessarily have to be part of the block, but could be an isolated index database." [Christian R.]
1. ERC-20 Token Standard Finalization [Fabian, Nick, or Hudson]
Everyone in the call was uin agreement that throw was a better solution than return false; on failed transactions, but it is better that this issue is decided in the EIPs itself as this is an ERC.
