    Ethereum Launches

    Vitalik Buterin and The Ethereum Foundation create the first blockchain-based turing-complete smart contract platform with the Frontier release. Read the Whitepaper

    • Codename: Frontier
    • Release: 30.07.2015
    • Block: 0

    Ice Age

    September 08 2015, the network implements an ‘Ice Age’ at block 200,000 introducing the Difficulty Bomb, a mechanism designed to move the network's consensus mechanism away from Proof-of-Work to Proof-of-Stake

    October 2015
    • Codename: Ice Age
    • Release: 08.09.2015
    • Block: 200,000

    Homestead Upgrade

    March 15 2016, Homestead is the second major version release of the Ethereum platform.

    March 2016
    • Codename: DAO Fork
    • Release: 20.07.2016
    • Block: 1,150,000

    Tangerine Whistle

    “Tangerine Whistle” - addressed immediate network health issues due to the DoS attacks, the upcoming “Spurious Dragon,” which is the second hard fork of the two-round hard fork response to the DoS attacks on the Ethereum network in September and October.

    June 2016
    • Codename: Tangerine Whistle
    • Release: 18.10.2016
    • Block: 2,463,000

    Spurious Dragon

    The Ethereum network was undergoing a hard fork at block number 2,675,000, which occured between on Tuesday, November 22, 2016. The Morden test network was undergoing a hard fork at block number 1,885,000.

    November 2016
    • Codename: Spurious Dragon
    • Release: 23.11.2016
    • Block: 2,675,000

    Byzantium

    The Byzantium hard fork is an update to ethereum’s blockchain that was implemented in October 2017 at block 4,370,000. It consisted of nine Ethereum Improvement Protocols (EIPs) designed to improve ethereum’s privacy, scalability and security attributes.

    October 2017
    • Codename: Byzantium
    • Release: 16.10.2017
    • Block: 4,370,000

    Constantinople

    The upgrade, known as Ethereum Constantinople, included several proposals to make the blockchain more efficient and pave the way for a move to Proof of Stake in future Ethereum updates. Ethereum traders, developers, and users alike were excited to see new upgrades to the Ethereum platform.

    February 2019
    • Codename: Constantinople
    • Release: 28.02.2019
    • Block: 7,280,000

    Petersburg

    Two long-anticipated upgrades appear to have officially activated on the ethereum blockchain, by now the world’s second-largest by market value. The sixth and seventh system-wide upgrades to the software, dubbed Constantinople and St. Petersburg, respectively, rolled out on the main network at block number 7,280,000.

    February 2019
    • Codename: Petersburg
    • Release: 28.02.2019
    • Block: 7,280,000

    Istanbul

    Regular small hard forks allow upgrades to be included in more timely and manageable way that large infrequent forks. Istanbul was approached with a fork-centric approach, where EIPs were proposed for the fork, reviewed then accepted. This resulted in many EIPs being proposed, in various states of readiness. This approach limits the amount of review time per EIP.

    December 2019
    • Codename: Istanbul
    • Release: 08.12.2019
    • Block: 9,069,000

    Muir Glacier

    Muir Glacier has only one improvement proposal, EIP 2384. This EIP will only delay the difficulty bomb for another 4,000,000 blocks, or approximately 611 days. This is the same approach done in the past on Ethereum.

    January 2020
    • Codename: Muir Glacier
    • Release: 01.01.2020
    • Block: 9,200,000

    Ethereum 2.0 Phase 0 launched

    On 1. December 2020 the Beacon Chain was launched after a deposit of over 2 Million ETH at present, this is the start to Transition Ethereum from Proof-of-Work(PoW) to a Proof-of-Stake(PoS) blockchain and this will act as the central coordination and consensus hub of Eth2.

    December 2020
    • Codename: ETH 2.0 Phase 0
    • Release: TBD
    • Block: TBD

    Berlin (planned)

    Accepted EIPs
    EIP-2315: Simple Subroutines for the EVM
    EIP-2537: BLS12-381 curve operations

    Proposed EIPs
    EIP-2046: Reduced gas cost for static calls made to precompiles
    EIP-2565: Repricing of the EIP-198 ModExp precompile
    EIP-1599: Remove Gas Refund to foght rising Gas cost which are exploited by people speculating on Gasprice. Due to rising Gas Cost Ethereum Network is right now unusuable for normal people, this sparked many Layer 2 Projects, and hurt ETH Marketshare, loosing it to PoA Networks like Binance Smart Chain.

    Early 2021
    • Codename: Berlin
    • Release: before Summer 2021
    • Block: TBD

    Ethereum 2.0 Phase 1 (planned)

    will create shard chains and connect them to the Beacon Chain.

    TBD
    • Codename: ETH 2.0 Phase 1
    • Release: 23.11.2016
    • Block: TBD

    Ethereum 2.0 Phase 2 (planned)

    will implement state execution in the shard chains. The current Ethereum 1.0 chain is expected to become one of the shards of Ethereum 2.0

    TBD
    • Codename: ETH 2.0 Phase 2
    • Release: TBD
    • Block: TBD
