Constantinople Progress

Agenda

1. Testing
2. Client Updates
3. Research Updates
4. Constantinople
   a. EIP 1014 Issues
   b. EIP 1218: Simpler blockhash refactoring. Looks like we are dropping this one unless someone speaks up, like, immediately.
   c. EIP 1283: 1283 is moving forward per discussions on the previous call and the core devs chat room.
5. Three competing EIPs to delay the difficulty bomb and reduce/maintain the block reward:
   a. EIP-858 - Delay bomb and reduce block reward to 1 ETH per block.
   b. EIP-1234 - Delay bomb and reduce block reward to 2 ETH.
   c. EIP-1295 - Delay bomb, keep rewards to 3 ETH, change other factors such as POW incentive structure.
   There is renewed interest from miners to implement ProgPoW.

Different articles/links regarding potential issuance reduction conversation:

• A Case for Ethereum Block Reward Reduction to 2 ETH in Constantinople (EIP-1234)

Agenda

1. Testing
2. Client Updates
3. Research Updates
4. Post EIP 1011 (Hybrid Casper) Spec Plans
   1. Now that EIP 1011 is deprecated, is there still the interest among client developers to have a joint testnet, a Ropsten-successor if you want to put it like that?
   2. If yes, and I assume most of us are interested in some effort like this, how could it look like if not like the hybrid Casper proposal?
   3. What smaller steps can/should we take in the meantime while waiting for casper+sharding? (can we just call it "shasper" now?)
5. Possibly changing network Id in Constantinopole (or, alternatively, the format of the handshake message to make it backwards-incompatible).](#50 (comment))
6. Constantinople hard fork timing and what to include (continuing conversation from last call).
   a. EIP 145: Bitwise shifting instructions in EVM: pretty well-formed, but not 100% implemented or tested.
   b. EIP 210: Blockhash refactoring.

   e. EIP 1087: Net gas metering for SSTORE operations.
   f. EIP 1014: Skinny CREATE2.
   g. Delay ice age?

Proposed Constantinople Timeline
Finalize EIPs that are being implemented: July 13th
Client implementation: July 16th - August 13th
Testing: August 13th - September 10th
Testnet: September 10th - October 1st
Launch: October 8th

This is not final and there will likely be changes. I am soliciting feedback from client devs and testers who will be working on this.

   3. EIP 208: ethereum/EIPs#208 Concerns [Martin H.S]
   i. A transaction hash no longer uniquely identifies an execution, since a transaction at least theoretically can be included in multiple blocks, or multiple times in a block.
   ii. Do we need to modify rpc-call which assumes hash = unique execution, to return a list of transactions instead of a single element?
   iii. What side-effects does the breaking of this invariant have on the clients?
   4. EIP 211 RETURNDATACOPY and RETURNDATASIZE: This is complete right? [Hudson]

Metropolis Discussion

Use this issue for discussion around Metro. I will update chart/todo list as comments come in.

Approximate ice age start (according to Vitalik):

• Around March 25th (3 months) - Block time is 15.2 sec.
• Around July 25th (6 months) - Block time is 29.7 sec.

Metropolis Todo

• Decide which EIPs will potentially be in Metro (by way of EIP acceptance)
• Based on chart, decide which EIPs can fit into metro and which ones will not
• Pick a block number for Ropsten/Mainnet Metropolis

EIP Implementation Chart

Note: The EIPs listed in the chart are not necessarily approved for Metro via the EIP acceptance process, but we want to get information as early as possible.

Agenda

1. ERC-20 Token Standard Finalization [Fabian, Nick, or Hudson]

• Point of contention: throw vs return false;

2. Metropolis updates/EIPs.

• a. Details and implementations of EIPs.
  • "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]
  • Concerns around the REVERT opcode introducing an economic change that may break things and revisiting cost/benefit analysis of the opcode. [Vitalik]
  • "Regarding EIP 96: should the gas price of BLOCKHASH already change from the beginning of the Metropolis, or from the block where the behavior of BLOCKHASH changes?" More info: https://github.com/ethereum/EIPs/pull/210/files#r117211219 [Yoichi]
  • "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]
  • "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]
  • "Regarding EIP 211 (RETURNDATACOPY): the behavior of reading out-of-bounds from the returndata buffer is under discussion." [Yoichi]
• b. Updates to testing.
  • Proposal: "Freeze" EIPs to allow for testing. [Yoichi]
• c. Any "subtleties" we need to work out.
• d. Review time estimate for testing/release.

3. [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.]

5. EIP 1057: ProgPOW, a programmatic Proof-of-Work - an alternate proof-of-work algorithm - “ProgPoW” - tuned for commodity hardware in order to close the efficiency gap available to specialized ASICs. Technical details.
6. EIP 210: Blockhash refactoring - @holiman wants to finalize a few points:
   a. the original intent (no semantic changes to BLOCKHASH -- only gas changes) versus the current spec (semantic changes), and
   b. whether to make it nicer to ABI-call it, and
   c. whether to add genesis lookup in there.
