Ameen Soleimani, a outstanding developer of X, criticized Ethereum’s reluctance to implement Poseidon precompile. in replace In a not too long ago shared article, Soleimani expressed concern about Ethereum’s reluctance to implement this hash operate, which is required for environment friendly zk proofs.
Insights into Poseidon’s precompilation delay
In keeping with Soleimani, this similar function might be utilized in different blockchains comparable to Solana, Starknet, and Stellar from 2020 to 2022. He criticized the Ethereum group as follows: All the time speaking about “default privateness” However they refuse to make the required technological upgrades to ensure that.
Soleimani argues that if the present scenario continues, privateness is not going to be really enabled on Ethereum as a result of a key factor is lacking: the zkEVM function.
eth geeks create a “privateness by default” roadmap, however don’t implement precompilation for Poseidon (Poseidon is essentially the most confirmed environment friendly hashing algorithm for verification with ZK proofs)

The developer claimed that the Starknet group tried to supply some degree of assist to the Ethereum chain however was turned down. Soleimani claims that Ethereum has privateness gaps and is a name to motion for the Ethereum group.
He’s of the opinion that Ethereum must adapt to the present ZK rollup necessities and enhance the chain. Particularly, EIP-5988 has proposed including Poseidon to EVM addresses beginning in 2022, however this has not been carried out. Improvement stays stalled, inflicting delays in native shielded transfers.
It is very important make clear that “precompiling” is a built-in, low-cost function that may considerably cut back Ethereum gasoline charges. So Ethereum’s continued use of Poseidon with out precompilation makes app privateness impractical at layer 1.
Soleimani claimed that Poseidon is already the “most battle-tested” hash operate and has loved utility within the ZK system, and opined that given its reliability, there is no such thing as a actual acceptable motive to delay its deployment.
He criticized Ethereum’s roadmap for persevering with to push privateness to layer 2 reasonably than layer 1 proudly owning it. Soleimani desires Layer 1 to proceed to have core zk primitives as a result of with out them personal transactions are too costly.
Privateness roadmap guarantees contradict sluggish implementation
The developer’s declare has some foundation, contemplating that Ethereum founder Vitalik Buterin outlined it in April 2025. New privateness roadmap.
Regardless of guarantees of significant dedication, implementation stays a problem and stays a controversial difficulty on this space.
Ernst & Younger’s Paul Brody acknowledged the cost-prohibitive nature of privateness options on Ethereum and expressed hope that blockchain may really be operational in 2026. Mr. Brody mentioned he wish to see it. Implementing privateness It’s turning into mainstream for customers and establishments.
