Ethereum co-founder Vitalik Buterin has proposed a new way to handle complex cryptographic calculations without putting extra pressure on Ethereum’s main network. His proposal, EIP-8288, would allow users to perform these calculations on their own devices, such as smartphones and computers, then send the network a small proof that the results are correct. This could reduce the amount of data Ethereum needs to process while making it easier for developers to use different types of cryptography.
Buterin’s idea is based on the view that Ethereum should not have to process every piece of data or repeat every calculation itself. Instead, the network could check proofs of work completed elsewhere. If adopted, this approach could help Ethereum support more cryptographic tools without requiring developers to add new built-in functions for each one. However, EIP-8288 remains a proposal, and its potential benefits will depend on how the system is developed and implemented.
Ultimately, precompiles and EVM are both the wrong place to put most cryptography support into Ethereum. The reason is that precompiles and EVM both operate on data that has to be included into the ethereum chain somehow, which realistically means included in a block as calldata. That space is limited – even with PeerDAS and blocks-in-blobs, there’s a practical cap of ~8 MB/s before it starts getting uncomfortable.
Remember: it’s not a blockchain. It’s a cryptographic world computer. Any data/computation that does not need to be in the “main thread” of data/execution should not be put into the main thread.
Instead, the correct solution is… EIP-8288 maximalism.
If you have any heavy computation that’s self-contained, compute it and STARK it client-side (this is quickly getting faster and faster, even on phones), and push the STARK through the EIP-8288 recursive aggregation mechanism. The chain sees the fact that the computation was done and what the result is; it never needs to see the actual data and computation.
This way everyone can use whatever cryptography they want, the Ethereum chain can be lean, and we never need to add more precompiles again.

EIP-8288 lets your phone do the hard work
Currently, the global Ethereum network has to individually calculate and verify the specific security lock on your wallet to approve any transaction, which takes time and energy. With this new proposal, your smartphone processor does all the heavy verification in the background before you reach the cash register.
Social media commentator @Aiyouyouu7733 supported this change, joking that Ethereum currently operates like a wildebeest trying to cross a river with an entire herd on its back. By letting everyone bring their own pre-verified signatures, the network stays incredibly light.
EIP-8288 maximalism makes sense — keep the main thread lean and let client-side STARKs handle the heavy crypto. Ethereum doesn’t need to carry every computation like a wildebeest crossing the river with the whole herd on its back. Everyone brings their own signatures, the chain stays light, and we never need another precompile. 🦬

However, moving this responsibility to personal devices creates a new physical challenge. Because the actual math is no longer handled by giant network computers, your personal phone must be strong enough to generate these complex security proofs instantly. Online observer @LFGCAPO highlighted this exact issue, noting that while the proposal cleans up the main network, it immediately shifts the waiting time to the user’s personal device.
With EIP-8288 still a draft, this is a cleaner target than adding a precompile for every signature family: prove the work client-side, aggregate dependencies, verify the result. The bottleneck shifts to proof-generation latency and dependable mempool aggregation. What phone-class benchmark would make this practical?

The user questioned exactly what type of modern smartphone processor will be required to make this background math happen fast enough so that a person isn’t standing awkwardly at a coffee shop waiting for their phone to generate a receipt.
The security risks and limits of the new system
Even if modern smartphones can handle the extra workload, pushing security checks to individual users exposes a deeper structural flaw in how the system handles future threats.
As traditional computers are replaced by ultra-fast quantum computers, standard digital locks will eventually be needed less. People will need to upgrade to highly complex “post-quantum” signatures to protect their savings from being hacked.
While Buterin’s new proposal allows users to attach these advanced future security locks without asking the network for permission, the underlying system still struggles with how it organizes all that incoming data.
Tech analyst @zkvoxels criticized the current strategy, arguing that Ethereum will continue to face massive delays until it completely separates where data is stored from where it is actually processed.
@VitalikButerin eth is going to have problems until they separate their data layer from execution
that’s honestly your main bottleneck
and you need a better post-quantum aggregate sig replacement than “let’s hash some stuff but only use those hashes once” which, let’s be honest, is garbage— zkvoxels (@zkvoxels) October 19, 2026
The user stated that the current plan for future-proof security, which involves generating temporary, single-use digital hashes, is essentially garbage. If the core network cannot efficiently organize and store these massive custom security files after the phone does the math, the system will still bottleneck, leaving everyday users dealing with frustrating delays.
What the upgrade could mean for everyday users
If this proposal officially passes as part of Ethereum’s upcoming upgrade, the daily experience of managing digital money will completely transform for the average person in some ways.
Independent software developers may no longer need official permission from the main network to introduce new security codes; they can build wallets that authorize payments using just an Apple Face ID scan or a Samsung fingerprint reader, bypassing complicated digital keys entirely.
Meanwhile, Buterin has warned that fast advances in artificial intelligence could weaken the security of some cryptographic systems within the next two years. Responding to Ethereum Foundation researcher Justin Drake’s call for the industry to enter a defensive “bunker mode,” Buterin said the risk extends beyond traditional quantum threats.
