Abstract
Don’t touch Kotti; allow ECIP1061, ECIP1078, and ECIP1086 (EIP2200, EIP2200Disable) to continue as specified and implemented there.
Set Mordor ECIP1078 activation to 778507 (equivalent to ECIP1061), and rollback to 750000.
Motivation
ECIP1061 specifies a hard fork “Aztlan” for ETC networks. (google it)
ECIP1078 specifies a hard fork “Phoenix” for ETC Networks (discussions here: https://github.com/ethereumclassic/ECIPs/issues/262).
ECIP1061 enables EIP2200.
ECIP1078 disables EIP2200
EIP2200 was incorrectly implemented in ethereum/go-ethereum, etclabscore/multi-geth, multi-geth/multi-geth, and paritytech/parityethereum clients, which together compose the lion’s share of ETC network providership. EIP2200 has since been (simply) corrected (in all impacted providers AFAIK).
ECIP1061 and ECIP1078 have equal activation block numbers on mainnet (10_500_839). But ECIP1061 has already been activated on testnets, while ECIP1078, with a later testnet activation, is not yet enabled on the testnets.
This means that an incorrect (and mainnet irrelevant) implementation of EIP2200 is live on testnets. This means that protocol providers publishing releases which include ECIP1078 for testnets are faced with a dilemma:
- Don’t correct EIP2200 before the testnets ECIP1078 fork.
- Do correct EIP2200 before the fork, but follow specification (ECIP1086) to “allow” the incorrect EIP2200 implementation.
- Do correct EIP2200 before the fork, but rollback the effected testnets to “reset” prior to the impact of the incorrect EIP2200 implementation.
There seem to be two major, sometimes contradictory, philosophies about ETC testnets:
A. Testnets are a public service; a place for ETC-based dapp developers to try out their stuff in public.
B. Testnets are a public test; a place to demonstrate network feature acceptance before equivalent changes risk actual value on ETC mainnet.
Specification
Accept and include ECIP1086 on Kotti testnet. This leaves ECIP1061, ECIP1078, and the current proposal for handling the EIP2200 in/correction as-is and unchanged.
Change Mordor testnet ECIP1078 activation number to 778507. This will place ECIP1061 and ECIP1078 activation at equal blocks, and they will activate simulaneously, just like they are scheduled to on mainnet. Reset Mordor testnet back to block 775000 (3507 blocks prior to its ECIP1061 – and, as proposed, ECIP1078 – activation).
Rationale
Kotti is a PoA network, so it doesn’t simulate (ie test) ETC mainnet in the first place (at least not well) since it uses different consensus rules. If it is a public simulation and test of ETC mainnet, it isn’t a good one. So we can follow the logic of A: Testnets-as-service.
Mordor is a PoW network, making it a better simulator of ETC mainnet. We can follow the logic of B: Testnets-as-test, and not only resolve the issue of EIP2200 correction, but improve the network’s simulation of mainnet activation for ECIP1061 and ECIP1078.
