An outline of important protocol development milestones for the year of 2020, including highlights from the ETC Core 2020 Roadmap.
Ethereum Classic core developers maintain rough consensus for the collaborative effort of achieving operational parity with sister chain Ethereum (ETH).
The ETC Cooperative to help contribute to the codebase of Vyper in collaboration with Ben Hauser who implemented the changes necessary into Vyper in order to allow us to target multiple versions of the EVM in order to have it working with ETC.
Ethereum Classic core developers implement ETH's Constaninople and Petersburg network protocol upgrades to maintain operational parity with its sister chain.
Second State, Vyperlang, and other teams are implementing or experimenting in bringing LLVM infrastructure to the EthereumStack. This is an alpha version of the EVM LLVM. It includes the complete, working LLVM backend pipeline for generating EVM binaries. Optimizations are limited. https://github.com/etclabscore/evm_llvm/releases/tag/v0.5_alpha
CoreGeth: An Ethereum Protocol Provider. Priority is given to reducing opinions around chain configuration, IP-based feature implementations, and API predictability. Upstream development from ethereum/go-ethereum is merged to this repository regularly, usually at every upstream tagged release. Every effort is made to maintain seamless compatibility with upstream source, including compatible RPC, JS, and CLI APIs, data storage locations and schemas, and, of course, interoperable node protocols. Applicable bug reports, bug fixes, features, and proposals should be made upstream whenever possible.
ECIP 1050: Status Codes moves to Final status. This standard outlines a common set of Status Codes in the same vein as HTTP statuses. This provides a shared set of signals to allow smart contracts to react to situations autonomously, expose localized error messages to users, and so on. https://ecips.ethereumclassic.org/ECIPs/ecip-1050
During Aztlán testnet implementations, Ethereum Classic core developers discover complications with ECIP 1061 and 1078 specs to add ETH's Istanbul network protocol upgrade. Meowbits of ETC Core documents the findings. As intended, the ETC testnets catch the issues and core developers go back to the drawing board.
Ethereum Classic core developers reach rough consensus on ECIP-1088 in an effort to implement ETH's Istanbul network protocol upgrade. Testnet implementations revealed issues with prior attempts in specs ECIP-1061 and ECIP-1078.
Core-Geth implements block activation values for ECIP1088, Ethereum Classic's planned Phoenix hard fork upgrade. Please upgrade to version v1.11.0 or later for Phoenix support for ETC. https://github.com/etclabscore/core-geth/releases
Phoenix testing begins on the Mordor PoW testnet on block 999,983. Core development teams have signaled that this is a complex implementation. Testing may uncover issues that delay this network upgrade, but Ethereum Classic will never rush to upgrade the mainnet. Network security is priority over development speed and arbitary timelines. https://expedition.dev/?network=mordor
Hyperledger Besu implemented ECIP-1088: Phoenix EVM and Protocol upgrades. Please upgrade to version v1.4.1 or later for Phoenix support for ETC. https://github.com/hyperledger/besu/releases
Developer bounty platform Gitcoin has partnered with Ethereum Classic Labs to offer bounties in ETC.
March 17 2020, Ethereum Classic's block rewards are reduced by 20% to 3.2 ETC per block per the bitcoin-inspired 5M20 emission schedule.
The Kotti PoA testnet is successfully recovered after Aztlán implementations. The signers coordinate and regain consensus in anticipation for a successful Phoenix implementation. https://expedition.dev/?network=kotti

Multi-Geth implements support for the Phoenix hard fork on Ethereum Classic mainnet, at block 10,500,839, scheduled around the beginning of June, 2020. Please upgrade to version v1.9.14 or later for Phoenix support for ETC. https://github.com/multi-geth/multi-geth/releases
Phoenix testing begins on the Kotti PoA testnet on block 2,200,013. Core development teams have signaled that this is a complex implementation. Testing may uncover issues that delay this network upgrade, but Ethereum Classic will never rush to upgrade the mainnet. Network security is priority over development speed and arbitary timelines. https://expedition.dev/?network=mordor
Improve ETC specific documentation and add to the website for end user consumption. https://ethereumclassic.org/development/guides
Core development teams have signaled that this upgrade has successfully passed testing analysis on the Mordor and Kotti testnets. Ethereum Classic will never rush to upgrade the mainnet. Network security is priority over development speed and arbitary timelines. The ETC miners, wallets, exchanges, payment processors begin updated their clients for the Phoenix Upgrade. https://medium.com/etc-core/top-miners-confirmed-to-support-phoenix-ethereum-classic-hard-fork-phoenix-status-update-bc8964424fd4

Ethereum Classic's Thanos upgrade releases to mainnet. The purpose of this update is to calibrate the epoch length used in DAG calculations. https://ethereumclassic.org/blog/2020-11-27-thanos-hard-fork-upgrade
Ethereum Classic's Thanos upgrade releases to mainnet. Etchash is the modified dagger hashimoto used by Ethereum Classic. It is comparable in it's behaviour to Ethereum Foundation's Ethash but allows for a long-term viability of GPU-Mining with cards that have low memory (3gb, 4gb, 6gb) available. https://github.com/eth-classic/etchash
With the long-term capture of healthy, decentralized hashrate via the Thanos update, the risk of 51% attacks is mitigated. The ETC participants shifts focus on network adoption. The development and mining communities engage in a thoughtful discussions about Ethereum Classic's risk to self-sovereignty via the development wing of the project. Various proposals are drafted by teams and discussed in the ecosystem while the Ethereum Classic project moves into 2021.
