On the Ethereum mainnet, this means checking whether a peer upgrded to <a class=\"chakra-link css-vezwxf\" href=\"https:\/\/blog.ethereum.org\/2015\/08\/04\/the-thawing-frontier\">Frontier Thawing<\/a> at block 200,000, then <a class=\"chakra-link css-vezwxf\" href=\"https:\/\/blog.ethereum.org\/2016\/02\/29\/homestead-release\">Homestead<\/a> at block 1,150,000, and so on all the way to the latest upgrade, <a class=\"chakra-link css-vezwxf\" href=\"https:\/\/blog.ethereum.org\/2022\/06\/16\/gray-glacier-announcement\">Gray Glacier<\/a>, which happened at block 15,050,000. <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-2124\">EIP-2124<\/a> specifies how this is handled. In typical network upgrades, which are triggered by a block height, this happens automatically as nodes use the block height of upcomming upgrades to filter peers.<\/p>\n<p class=\"chakra-text css-gi02ar\">For The Merge, this was not possible because the upgrade was triggered using a <span class=\"chakra-text css-ons8vw\">total difficulty<\/span> value rather than a block number. The rationale for this choice is explained in <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-3675\">EIP-3675<\/a>:<\/p>\n<blockquote class=\"chakra-code css-gk0tva\">\n<p class=\"chakra-text css-gi02ar\">Using a pre-defined block number for the hardfork is unsafe in this context due to the PoS fork choice taking priority during the transition.<\/p>\n<\/blockquote>\n<blockquote class=\"chakra-code css-gk0tva\">\n<p class=\"chakra-text css-gi02ar\">An attacker may use a minority of hash power to build a malicious chain fork that would satisfy the block height requirement. Then the first PoS block may be maliciously proposed on top of the PoW block from this adversarial fork, becoming the head and subverting the security of the transition.<\/p>\n<\/blockquote>\n<blockquote class=\"chakra-code css-gk0tva\">\n<p class=\"chakra-text css-gi02ar\">To protect the network from this attack scenario, difficulty accumulated by the chain (total difficulty) is used to trigger the upgrade.<\/p>\n<\/blockquote>\n<p class=\"chakra-text css-gi02ar\">To minimize changes to the protocol during its most complex upgrade since launch, the design for The Merge excluded EIP-2124 compatibility. This means an additional upgrade must now be done to add this. It is important to note that the only change introduced as part of this upgrade is specifying a block number that nodes can use to identify peers who have gone through The Merge. No other functionality is introduced or deprecated as part of this upgrade.<\/p>\n<h2 class=\"chakra-heading group css-1kpzc4q\" id=\"upgrade-information\" data-group=\"true\"><a class=\"chakra-link css-128fqrf\" aria-label=\"upgrade information permalink\" href=\"#upgrade-information\"><svg viewbox=\"0 0 24 24\" focusable=\"false\" class=\"chakra-icon css-173jpr1\"><g fill=\"currentColor\"><path d=\"M10.458,18.374,7.721,21.11a2.853,2.853,0,0,1-3.942,0l-.892-.891a2.787,2.787,0,0,1,0-3.941l5.8-5.8a2.789,2.789,0,0,1,3.942,0l.893.892A1,1,0,0,0,14.94,9.952l-.893-.892a4.791,4.791,0,0,0-6.771,0l-5.8,5.8a4.787,4.787,0,0,0,0,6.77l.892.891a4.785,4.785,0,0,0,6.771,0l2.736-2.735a1,1,0,1,0-1.414-1.415Z\"\/><path d=\"M22.526,2.363l-.892-.892a4.8,4.8,0,0,0-6.77,0l-2.905,2.9a1,1,0,0,0,1.414,1.414l2.9-2.9a2.79,2.79,0,0,1,3.941,0l.893.893a2.786,2.786,0,0,1,0,3.942l-5.8,5.8a2.769,2.769,0,0,1-1.971.817h0a2.766,2.766,0,0,1-1.969-.816,1,1,0,1,0-1.415,1.412,4.751,4.751,0,0,0,3.384,1.4h0a4.752,4.752,0,0,0,3.385-1.4l5.8-5.8a4.786,4.786,0,0,0,0-6.771Z\"\/><\/g><\/svg><\/a>Upgrade Information<\/h2>\n<h3 class=\"chakra-heading group css-xuzltg\" id=\"timing\" data-group=\"true\"><a class=\"chakra-link css-128fqrf\" aria-label=\"timing permalink\" href=\"#timing\"><svg viewbox=\"0 0 24 24\" focusable=\"false\" class=\"chakra-icon css-173jpr1\"><g fill=\"currentColor\"><path d=\"M10.458,18.374,7.721,21.11a2.853,2.853,0,0,1-3.942,0l-.892-.891a2.787,2.787,0,0,1,0-3.941l5.8-5.8a2.789,2.789,0,0,1,3.942,0l.893.892A1,1,0,0,0,14.94,9.952l-.893-.892a4.791,4.791,0,0,0-6.771,0l-5.8,5.8a4.787,4.787,0,0,0,0,6.77l.892.891a4.785,4.785,0,0,0,6.771,0l2.736-2.735a1,1,0,1,0-1.414-1.415Z\"\/><path d=\"M22.526,2.363l-.892-.892a4.8,4.8,0,0,0-6.77,0l-2.905,2.9a1,1,0,0,0,1.414,1.414l2.9-2.9a2.79,2.79,0,0,1,3.941,0l.893.893a2.786,2.786,0,0,1,0,3.942l-5.8,5.8a2.769,2.769,0,0,1-1.971.817h0a2.766,2.766,0,0,1-1.969-.816,1,1,0,1,0-1.415,1.412,4.751,4.751,0,0,0,3.384,1.4h0a4.752,4.752,0,0,0,3.385-1.4l5.8-5.8a4.786,4.786,0,0,0,0-6.771Z\"\/><\/g><\/svg><\/a>Timing<\/h3>\n<p class=\"chakra-text css-gi02ar\">This upgrade will happen on Sepolia at block <strong><span class=\"chakra-text css-ons8vw\">1735371<\/span><\/strong>, expected on August 17, 2022.<\/p>\n<p class=\"chakra-text css-gi02ar\">Note that a similar upgrade will be announced for Goerli and mainnet after these networks have transitioned to proof-of-stake.<\/p>\n<p class=\"chakra-text css-gi02ar\">Ropsten will <strong>not<\/strong> be upgraded since it is now considered deprecated, along with Rinkeby and Kiln.
