Once established, the account acquires the new code\u2019s functionalities (e.g., batching, sponsorship, authentication logic, etc.). Since selecting a delegation target assigns a substantial amount of control, EIP-7702 mandates several safety measures:<!-- --><\/p>\n<p><!-- --><\/p>\n<ul role=\"list\" class=\"css-1onhfjo\">\n<li class=\"css-cvpopp\"><strong>Chain-specific delegations<!-- --><\/strong>: by default, a delegation is exclusively valid on a particular chain ID, preventing the same authorization from being utilized across various networks.<!-- --><\/li>\n<li class=\"css-cvpopp\"><strong>Nonce-restricted delegations<!-- --><\/strong>: authorizations can be linked to the account&#8217;s current nonce, automatically invalidating them once the nonce rises.<!-- --><\/li>\n<li class=\"css-cvpopp\"><strong>Revocation capability<!-- --><\/strong>: the owner of the EOA can always create an alternative EIP-7702 authorization that cancels or replaces the existing delegation code, avoiding a permanent lock-in if an issue arises.<!-- --><\/li>\n<\/ul>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">For optimal practices regarding the use of EIP-7702, check out <!-- --><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-ug8vf0\" href=\"https:\/\/ethereum.org\/en\/roadmap\/pectra\/7702\/\">this page<!-- --><\/a>.<!-- --><\/p>\n<p><!-- --><\/p>\n<h3 class=\"chakra-heading css-145upk7\" id=\"validator-ux-improvements\">Validator UX Enhancements<!-- --><\/h3>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">Three new EIPs within Pectra enhance the validator experience: <!-- --><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-ug8vf0\" href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-7251\">7251<!-- --><\/a>, <!-- --><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-ug8vf0\" href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-7002\">7002<!-- --><\/a> and <!-- --><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-ug8vf0\" href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-6110\">6110<!-- --><\/a>.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">The first, EIP-7251, elevates the maximum balance a validator can accrue rewards on from 32 ETH to 2048 ETH, through an opt-in update of withdrawal credential type.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">For stakers, this enables the compounding of rewards. Previously, any rewards accrued beyond a validator&#8217;s 32 ETH deposit were not considered towards their active stake. Stakers aiming to stake beyond 32 ETH could only do so in fixed increments of 32 ETH, depending on staking pools for amounts in between. With EIP-7251, both existing and new validators can be configured to earn rewards on every ETH staked, up to 2048 ETH per validator.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">This EIP also empowers larger operators to consolidate multiple validators by combining several 32 ETH validators. This alleviates the bandwidth requirement for the network as a whole. For a deeper understanding of the mechanics, refer to <!-- --><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-ug8vf0\" href=\"https:\/\/ethereum.org\/en\/roadmap\/pectra\/maxeb\/\">this page<!-- --><\/a>.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">EIP-7002 further expands validators&#8217; capabilities by introducing execution layer triggerable withdrawals. Before this EIP, only a validator&#8217;s active signing key could initiate an exit. Now, if an Ethereum address is designated as a withdrawal credential, it can also trigger an exit. This reduces trust assumptions in delegation arrangements, as the owner of the funds &#8212; whether a person managing an EOA or a DAO-controlled smart contract &#8212; can always trustlessly initiate an exit.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">Lastly, EIP-6110 eliminates a lingering remnant of pre-merge Ethereum: the delay between validator deposits and their inclusion in the deposit queue. In the pre-merge era, the Beacon Chain had to wait 2048 blocks before processing validator deposits to account for possible proof-of-work re-organizations. This is no longer necessary!<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">With EIP-6110, deposit processing delays have been reduced from around 9 hours to approximately 13 minutes. Teku engineers Lucas Saldanha and Stefan Bratanov presented the details of EIP-7002 and EIP-6110 in their <!-- --><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-ug8vf0\" href=\"https:\/\/www.youtube.com\/watch?v=EyDChjFQEkQ\">joint Devcon SEA presentation<!-- --><\/a>.<!-- --><\/p>\n<p><!-- --><\/p>\n<h3 class=\"chakra-heading css-145upk7\" id=\"blob-scaling-oo\">Blob Scaling .oO<!-- --><\/h3>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">The final significant alteration inPectra is EIP-7691, which enhances Ethereum\u2019s blob handling capacity twofold!<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">Blobs, which were unveiled in the <!-- --><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-ug8vf0\" href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-7569\">Dencun upgrade<!-- --><\/a>, serve as temporary data storage that L2s can utilize to submit compressed transaction details and proofs to Ethereum L1. Since their implementation, they&#8217;ve significantly decreased L1 costs for L2s by 10-100 times, leading to drastically lower transaction costs for L2 users.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">Presently, the Ethereum mainnet allows an average of 3 blobs per block, with a peak of 6 to manage spikes in demand. Following EIP-7691, these figures will rise to an average of 6 and a ceiling of 9.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">In contrast to <!-- --><span class=\"chakra-text css-ons8vw\">CALLDATA<\/span>, which nodes keep permanently, blobs are removed from the network following 4096 epochs (~18 days). This limits the storage space they can occupy. The limiting factor for blobs is bandwidth, as they must be disseminated throughout Ethereum&#8217;s peer-to-peer network. To mitigate the bandwidth increase that EIP-7691 could bring, Pectra also introduces EIP-7623, which places a cap on the maximum size of a block.<!-- --><\/p>\n<p><!-- --><\/p>\n<p class=\"chakra-text css-gi02ar\">To sustain Ethereum\u2019s data handling growth without a proportional rise in bandwidth demands, we must transition from a scenario where every node holds every blob to one where nodes keep only a fraction and sample the network to verify the remaining blob information. The good news is that efforts to facilitate this transition are already in motion!
