After Sepolia, only Goerli\/Prater will need to be merged before moving to mainnet. Other testnets will be considered deprecated post-merge, as explained <a class=\"chakra-link css-vezwxf\" href=\"https:\/\/blog.ethereum.org\/2022\/06\/21\/testnet-deprecation\">in a recent post<\/a>.<\/p>\n<p class=\"chakra-text css-gi02ar\">The Merge is different from previous Ethereum upgrades in two ways. First, node operators need to update both their consensus layer (CL) and execution layer (EL) clients in tandem, rather than just one of the two. Second, the upgrade activates in two phases: the first at an epoch height on the Beacon Chain and the second upon hitting a <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-3675#terminal-total-difficulty-vs-block-number\"><span class=\"chakra-text css-ons8vw\">Total Difficulty<\/span><\/a> value on the execution layer.<\/p>\n<p class=\"chakra-text css-gi02ar\">Sepolia has already run through the Bellatrix upgrade on the Beacon Chain.

It starts with a network upgrade on the consensus layer, triggered by an epoch height. This is followed by the execution layer&#8217;s transition from proof-of-work to proof-of-stake, triggered by a specific <span class=\"chakra-text css-ons8vw\">Total Difficulty<\/span> threshold, called the <span class=\"chakra-text css-ons8vw\">Terminal Total Difficulty<\/span> (<span class=\"chakra-text css-ons8vw\">TTD<\/span>).<\/p>\n<p class=\"chakra-text css-gi02ar\">On <strong>June 20, 2022<\/strong>, at epoch <strong><span class=\"chakra-text css-ons8vw\">100<\/span><\/strong>, the <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/ethereum\/consensus-specs\/tree\/dev\/specs\/bellatrix\">Bellatrix<\/a> upgrade prepared the Sepolia Beacon Chain for The Merge. At that point, CL clients began listening for a <span class=\"chakra-text css-ons8vw\">TTD<\/span> value to be hit on the proof-of-work chain.<\/p>\n<p class=\"chakra-text css-gi02ar\">Because the hash rate of proof-of-work testnets is very volatile, the <span class=\"chakra-text css-ons8vw\">TTD<\/span> value was first set to an exceedingly high value, <span class=\"chakra-text css-ons8vw\">100000000000000000000000<\/span>. At Sepolia&#8217;s current hash rate, it would take hundreds of years to reach this value.<\/p>\n<p class=\"chakra-text css-gi02ar\">With Bellatrix now live, an updated <span class=\"chakra-text css-ons8vw\">TTD<\/span> value of <strong><span class=\"chakra-text css-ons8vw\">17000000000000000<\/span><\/strong> has been chosen for the transition. It is expected to be hit within the next few days. When this new <span class=\"chakra-text css-ons8vw\">TTD<\/span> is hit or exceeded, the execution layer part of the transition, codenamed <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/ethereum\/execution-specs\/blob\/master\/network-upgrades\/mainnet-upgrades\/paris.md\">Paris<\/a>, will start. Again, note that hash rate on Sepolia is notoriously variable, so the actual time at which the <span class=\"chakra-text css-ons8vw\">Terminal Total Difficulty<\/span> takes place may fluctuate.<\/p>\n<p class=\"chakra-text css-gi02ar\">Once the execution layer has exceeded the <span class=\"chakra-text css-ons8vw\">TTD<\/span>, the next block will be solely produced by a Beacon Chain validator. We consider The Merge to have been completed once the Beacon Chain has finalized this block. Assuming normal network conditions, this should happen 2 epochs, or approximately 13 minutes, after the first post-TTD block is hit!<\/p>\n<p class=\"chakra-text css-gi02ar\">A new JSON-RPC block tag, <span class=\"chakra-text css-ons8vw\">finalized<\/span>, returns the latest finalized block or an error if no such post-merge block exists. This tag can be used for applications to check if The Merge has been completed. Similarly, smart contracts can <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-4399#using-264-threshold-to-determine-pos-blocks\">query the <span class=\"chakra-text css-ons8vw\">DIFFICULTY<\/span> opcode (<span class=\"chakra-text css-ons8vw\">0x44<\/span>)<\/a>, renamed to <span class=\"chakra-text css-ons8vw\">PREVRANDAO<\/span> post-merge, to determine if The Merge has happened.

a node operator, what should I do?<\/h3>\n<p class=\"chakra-text css-gi02ar\">Post-merge, an Ethereum full node will combine a consensus layer client, which runs the proof-of-stake Beacon Chain, and an execution layer client, which manages the user-state and runs the computations associated with transactions. These communicate over an authenticated port using a new set of JSON RPC methods called the <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/ethereum\/execution-apis\/tree\/main\/src\/engine\">Engine API<\/a>. The EL and CL client authenticate each other using a JWT secret. <strong>Node operators should refer to their clients&#8217; documentation for instructions about how to generate and configure these.<\/strong><\/p>\n<p class=\"chakra-text css-gi02ar\">In other words, if you were already running a node on the Beacon Chain, you now also need to run an execution layer client. Similarly, if you were running a node on the current proof-of-work network, you will need to run a consensus layer client. For them to communicate securely, a JWT token must be passed to each client.<\/p>\n<p class=\"chakra-text css-gi02ar\">It is worth emphasizing that while they are both part of consensus layer client releases, running a Beacon Node is distinct from running a Validator Client. Stakers must run both, but node operators only need the former. <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/docs.ethhub.io\/ethereum-roadmap\/ethereum-2.0\/eth-2.0-client-architecture\/\">This post<\/a> explains the difference between both components in more detail.<\/p>\n<p class=\"chakra-text css-gi02ar\">Also, note that each layer will maintain an independent set of peers and expose its own APIs.

Below are some notes to prepare for this. Again, no action is required now.<\/p>\n<blockquote class=\"chakra-code css-gk0tva\">\n<p class=\"chakra-text css-gi02ar\">As explained above, <strong>validators on the Beacon Chain will need to run an execution layer client after The Merge, in addition to their consensus layer clients.<\/strong> Pre-merge, this was strongly recommended, but validators could have outsourced these functions to third-party providers. This was possible because the only data required on the execution layer were updates to the deposit contract.<\/p>\n<\/blockquote>\n<blockquote class=\"chakra-code css-gk0tva\">\n<p class=\"chakra-text css-gi02ar\">Post-merge, validators need to ensure that transactions in blocks that they create and attest to are valid. To do this, each beacon node must be paired with an execution layer client. Note that multiple validators can still be paired to a single beacon node &amp; execution layer client combo. While this expands validators&#8217; responsibilities, it also gives a validator who proposes a block the right to its associated transaction priority fees (which currently go to miners).<\/p>\n<\/blockquote>\n<blockquote class=\"chakra-code css-gk0tva\">\n<p class=\"chakra-text css-gi02ar\">While validator rewards accrue on the Beacon Chain and will require a subsequent network upgrade to be withdrawn, transaction fees will continue to be paid, burned, and distributed on the execution layer.

As explained in a <a class=\"chakra-link css-vezwxf\" href=\"https:\/\/blog.ethereum.org\/2021\/11\/29\/how-the-merge-impacts-app-layer\">previous post<\/a>, The Merge will have only minimal impact on a subset of contracts deployed on Ethereum, none of which should be breaking.
