QuantumEVM, a layer-1 chain appropriate with the Ethereum Digital Machine (EVM) and designed with quantum resistance in thoughts from the bottom up, has launched its testnet (testnet) The undertaking will go dwell on March 17, as defined by Ian Smith, the undertaking's CEO and technical director.
The principle objective of QuantumEVM is to allow Ethereum ecosystem buildings (decentralized functions, good contracts, and many others.). Simply migrate to networks geared toward securing post-quantum threats.with out shedding compatibility with present instruments akin to wallets.
The supervisor introduced that the crew would want to utterly redesign the EVM's reminiscence structure to make it immune to quantum pc assaults.
The core modifications are the migration of 20-byte addresses, the Ethereum normal, and all supported networks. as much as 32 byte deal with.
The CEO additionally revealed that QuantumEVM runs on Cellframe, an open source-based community for scalability and post-quantum safety, and makes use of a proof-of-stake (PoS) consensus mechanism, permitting functions and good contracts to be migrated virtually straight from Ethereum whereas sustaining compatibility with the EVM normal.
Moreover, though Smith assures that QuantumEVM makes use of post-quantum cryptography (PQC), neither he nor the undertaking documentation reveals which particular algorithms might be carried out.
The undertaking documentation states: The technique is “hybrid and configurable”: The system makes use of a number of fundamental schemes and lets you select from them by a configuration file, with the intention of facilitating speedy migration within the occasion of future quantum assaults.
Over the following “three months,” the undertaking will embody totally homomorphic encryption (FHE), which permits knowledge to be processed with out decrypting it, and PQC acceleration with graphics processing models (GPUs), based on Smith.
Why isn't 20 bytes sufficient?
Ethereum addresses are 160 bits (20 bytes) and are generated utilizing a hash operate. As Smith defined, this measurement makes it weak to the BHT (Brassard-Høyer-Tapp) algorithm, a 1997 quantum technique designed to seek out collisions in hash features.
In keeping with QuantumEVM executives, for 20-byte addresses, BHT requires roughly 10¹⁶ quantum operations to seek out collisions and violate these addresses. That’s, two totally different inputs that produce the identical deal with. You could possibly entry another person's funds with out stealing their personal keys..
Smith mentioned the dangers are larger with Ethereum than with Bitcoin. EVM community good contract addresses are generated utilizing a hash and a nonce. Creates easier and easier-to-attack quantum circuits. Bitcoin, then again, obtains addresses by a non-public key, a public key, and two totally different hash features, making the circuitry required for an assault extra complicated.
The answer carried out by QuantumEVM is: Transfer to 256-bit (32-byte) deal with. At this scale, Smith estimates that the identical BHT assault would require roughly 2⁸5 operations, a threshold that’s virtually unfeasible.
Can the identical resolution be utilized to Ethereum?
Technically sure. Since 2021, a dialogue thread concerning the transition from 20 to 32 bytes for addresses has existed on Ethereum Magicians, a reference discussion board for Ethereum builders, however the final remark occurred in August 2025, indicating that the Ethereum ecosystem has different priorities.
This proposal features a new opcode for producing 32-byte addresses and a compatibility mechanism with present contracts.
The obstacles are structural, not technical. Nearly all the Ethereum ecosystem, contracts, wallets, exchanges, indexers, and bridges based mostly on ERC-20 and ERC-721 requirements anticipate 20-byte addresses.
Transferring means huge arduous forka brand new technology of addressing and compression mechanisms to keep up compatibility with legacy contracts. As of March 2026, there are not any formal proposals underway or a transparent date for the transition.
Different options and roadmap
Along with the deal with redesign, Smith additionally mentioned different options of the QuantumEVM community. Transactions observe a strict first-come, first-served foundation. This eliminates the potential of a validator altering the order of operations to extract worth on the expense of the person. This can be a follow referred to as MEV (Most Extractable Worth).
Moreover, the price of gasoline is fastened in greenback phrases and modifications inversely with the worth of the native QEVM token. The undertaking additionally has bridges to Ethereum and BNB Sensible Chain.
In keeping with the printed roadmap, the undertaking is contemplating a public sale of tokens, itemizing on a centralized trade, and beginning the primary safety audit within the first quarter of 2026.
Lastly, for Q2, mainnet launch, staking, full availability of EVM and DeFi instruments are predicted. The corporate plans to launch wallets for Android and iOS within the third quarter.
