The success of the Ropsten test lights the way for the full Merge<\/h2>\n

This story has been updated following the successful Ropsten testnet merge. The original article was published on June 2nd, 2022.<\/em><\/p>\n

The 8th of June, 2022, will go down as an important milestone in the journey towards the <\/strong>Ethereum<\/strong> Merge. The Ropsten testnet merge, which was seen as a final dress rehearsal before the full Merge, showed developers that everything is in place and ready to go. But what is the Ethereum Merge and what will it achieve?<\/strong><\/p>\n

Summary<\/strong><\/p>\n

\n
• The Ropsten merge was executed June 8th. It was a dress rehearsal for the main event and gave the Ethereum team the chance to run tests and simulations.<\/em><\/span><\/li>\n
• Benefits of the Merge include faster and cheaper transactions, reductions in energy consumption for validations, deactivation of the Difficulty Time Bomb and a potential spike in the price of ETH.<\/em><\/strong><\/li>\n
• The Ropsten testnet is a sandbox network where developers can test their code and updates in a safe environment that won\u2019t affect the Ethereum mainnet.<\/em><\/strong><\/li>\n<\/ul>\n

  Ethereum was founded and developed in December 2013 by Vitalik Buterin, alongside Anthony Di Iorio, Mihai Alisie, Amir Chetrit and Charles Hoskinson. Hoskinson later went on to found the Cardano blockchain platform.<\/p>\n

  Since then, Ethereum has grown to be the second largest blockchain by cryptocurrency market cap, behind Bitcoin. ETH, the network\u2019s native token, is the method of payment people use to make transactions on the blockchain.<\/p>\n

  While Ethereum is the second largest network by the current value of its cryptocurrency, it is, by most other metrics, the biggest blockchain in the world. In 2021, it surpassed Bitcoin in transaction numbers. The network is number one for the most number of dapps built on it. Ethereum also takes first place for the number of NFTs that are developed and traded on its blockchain.<\/p>\n

  Now, reports have emerged that Ethereum is close to completing the fabled Merge, apparently as soon as August this year. The recent successful Ropsten testnet trial run was another step closer towards Ethereum developers hitting this timeline.<\/p>\n

  First off, what is the Ethereum Merge and why is it happening?<\/h2>\n

  The Merge, as the Ethereum community calls it, is the blockchain\u2019s shift from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS) model. This means that instead of people needing to run powerful computer processes in order to mine ETH, they can deposit ETH in exchange for rewards.<\/p>\n

  Pre-Merge, the Ethereum Mainnet runs in parallel with the Beacon Chain. The former functions as a PoW system while the latter is PoS. With the Merge, these two networks will come together and operate as one structure.<\/p>\n

  Ethereum\u2019s developers are pushing forward with the Merge for two main reasons:<\/p>\n

  \n
  • Costs. These things often come down to money and value. By switching from PoW to PoS, the issuance of ETH is expected to drop by about 90%. Less ETH available and stable demand leads to higher prices.<\/li>\n
  • The Difficulty Time Bomb. Some of the phrasing surrounding the Merge starts to sound a bit like a disaster film. But in a nutshell, the Difficulty Time Bomb refers to an element encoded within the blockchain that intentionally slows down the network. It was supposed to act as encouragement for developers to work towards a PoS model. By switching over to this system, they will negate the effects of the Time Bomb.<\/li>\n<\/ul>\n

    Who is carrying out the Merge, and when?<\/h2>\n

    Ethereum developers are currently undertaking the work. Tim Beiko, Community Manager at the Ethereum Foundation, is one of the main people carrying out development on the Merge. Core developer Preston Van Loon has also been at the forefront of talk around this piece of news. \u2018As far as we know, if everything goes to plan, August \u2013 it just makes sense. If we don\u2019t have to move [the Difficulty Bomb], let\u2019s do it as soon as we can.\u2019<\/p>\n

    Justin Drake, another member of the Ethereum Foundation, said at the Permissionless Conference on May 19th, that there\u2019s a \u2018strong desire to make this happen before the Difficulty Time Bomb in August\u2019.\u00a0<\/p>\n

    The Ethereum Foundation operates as a not-for-profit organization and the main task is the management of the Ethereum blockchain. Alongside this, the Foundation promotes, researches and educates about all things blockchain, web3 and, of course, Ethereum.<\/p>\n

    Justin Drake\u2019s \u201cbefore August\u201d date seems to be the deadline for the Merge towards which everyone is working. So expect it to happen any time over the next two or three months.<\/p>\n

    What difference will the Merge make?<\/h2>\n

    As mentioned above, there are two main reasons for the Merge: value creation and a safe deactivation of the Difficulty Time Bomb.<\/p>\n

    But there are more benefits that users and the wider world can expect post-June 8th:<\/p>\n

    \n
    • Reduction in the amount of energy required for transaction validation. Some sources say that transactions will require ~99.95% less energy after the Merge takes place.<\/li>\n
    • Long-term sustainability is a key reason for the Merge. The changes that Ethereum\u2019s developers make now will have long-term benefits and enable the team to move on to the next stages in their roadmap. The post-merge upgrades will not be possible without the Merge.\u00a0<\/li>\n<\/ul>\n

      Unfortunately, as Tim Beiko told Fortune magazine, the Merge will not dramatically reduce gas fees immediately. These reductions will (apparently) happen next year, when Shard Chains are introduced. These will make Ethereum more scalable and should cut down on the congestion issues that every Ethereum user has come to know, and pay for.<\/p>\n

      The Ropsten Test<\/h2>\n

      The dress rehearsal went almost as smoothly as the development team hoped. Ethereum Foundation developer Parithosh Jayanthi noted how that \u2018the Ropsten testnet hit terminal total difficulty (TTD) at ~16:00 UTC\u2019.<\/p>\n

      The Ropsten testnet hit TTD at ~16:00 UTC (~2h after the planned time, great accuracy for PoW standards!). The chain was at ~99.2% participation rate with healthy proposals and sync committee performance \u2013 Pretty much the perfect beacon chain to merge, easy to see what breaks!<\/p>\n
