If Ethereum's EIP-8182 is implemented, it could become the world's largest privacy chain, while potentially absorbing liquidity from some other privacy coins (and even users with privacy needs on BTC).
How to understand this?
Current Ethereum is completely public and transparent; when you transfer ETH, everyone can see the sender, receiver, and amount on the chain.
Existing privacy solutions (like Tornado, Railgun, Aztec, etc.) are third-party dApps, which have several pain points:
• The "anonymity set" (mixer pool size) of each project is small, reducing privacy effectiveness;
• Different projects are incompatible, fragmenting users;
• Vulnerable to regulatory scrutiny (Tornado Cash has been sanctioned by OFAC).
What exactly is EIP-8182?
Proposed by developer Tom Lehman in March 2026, EIP-8182, Private ETH and ERC-20 Transfers, is currently in the draft stage.
It aims to directly embed a unified shared privacy pool (shared shielded pool) + zero-knowledge proof (ZK) precompilation at the Ethereum protocol layer (L1).
Main features include:
• A super-large shared pool: All wallets and all dApps use the same pool, leading to an explosively large anonymity set (Ethereum is the largest public chain with the most users and capital, theoretically offering the strongest privacy).
• Native support: Direct private transfers for ETH and any ERC-20 tokens, as simple as a regular transfer.
• System contract + split-proof architecture: The pool is a fixed-address system contract with no administrator, no governance token, no upgrade permissions, and can only be upgraded via a hard fork (highly decentralized).
• Zero-knowledge proofs: Uses ZK technology to prove "funds came from the pool, but the specific transaction is unknown," achieving complete privacy.
• No protocol fees: The pool itself charges no fees; users only pay normal Gas.
If EIP-8182 is implemented:
Then, it would make Ethereum the world's largest chain in terms of privacy, attracting institutional and user liquidity, competing with privacy tokens like Zcash/Monero/Railgun for market share in the privacy sector, and potentially drawing some privacy-demanding users currently on BTC to switch.
• Ethereum itself has the largest ecosystem and the strongest liquidity;
• Once native privacy is realized and usable by everyone, its anonymity set would far exceed that of existing privacy chains like Zcash, Monero, Railgun, etc.;
• This essentially turns "privacy" into a native function of Ethereum, not an add-on, directly upgrading ETH from a "transparent public chain" to the "largest privacy public chain."
Finally, considering institutional compliance issues, if EIP-8182 passes, it could combine with Zama, adding FHE contracts on top of the privacy pool to achieve "strong privacy + regulatory compliance."
