TL;DR:
This Friday, infrastructure firm QuFi Network unveiled its post-quantum verification platform alongside an operational technical demonstration on the Bitcoin Testnet4 network.
The development is based on an operational decoupling between transaction validation and final settlement. Through this framework, a decentralized network of nodes processes quantum-resistant signatures before transactions are formally recorded on the blockchain’s ledger.
The Bitcoin Testnet4 demonstration utilized a synthetic token called uBTC. This system verifies BTC collateral reserves and issues compact cryptographic proofs that govern value transfers. When executing final redemptions or swaps, the operation settles as an ordinary transaction on the Bitcoin network.
An industry source noted that this external methodology aims to alleviate the storage, bandwidth, and computational burdens that processing post-quantum signatures directly on the base layer of existing networks would entail.
The protocol’s design relies on three algorithms approved by the U.S. National Institute of Standards and Technology (NIST). For primary digital signatures, the platform utilizes ML-DSA-65. It also incorporates SLH-DSA as a hash-based fallback mechanism and deploys ML-KEM-1024 in key encapsulation processes for secure credential exchanges.
QuFi’s initiative aligns with other security trials conducted by industry developers in recent weeks.
During August 2026, the StarkWare team evaluated an experimental quantum-resistant transaction on the Bitcoin mainnet without requiring a network hard fork. According to technical records from that trial, the operation required several hours of computational processing, incurred an estimated network fee between $150 and $200, and necessitated a non-standard format submitted directly to a miner.
Concurrently, in late August 2026, Blockstream researchers published a Bitcoin Improvement Proposal (BIP) centered on SHRINCS. Technical documentation describes SHRINCS as a post-quantum signature scheme engineered to minimize transaction sizes.
A market technical report indicates that this scheme relies on stateful signatures to compress data, requiring wallets to track previously used keys and introducing operational complexity during preliminary evaluation stages.
At the institutional level, banking entities and regulators across Europe, the Middle East, and Asia participated in August 2026 pilot tests involving post-quantum wallets and on-chain transfers implementing the ML-DSA-65 algorithm. Meanwhile, the Ethereum Foundation recently replaced the Poseidon hash function in its quantum roadmap with established algorithms such as SHA or BLAKE.
Industry analysts highlight that real-world asset (RWA) tokenization frameworks—such as 30-year bonds and debt instruments—demand long-term cryptographic contingencies against the maturation of quantum computers. According to QuFi’s development team, the platform plans to expand its verification layer to Solana, Stellar, and Ethereum Virtual Machine (EVM)-compatible environments.
To structure the decentralization of its service, QuFi Network simultaneously opened applications for its Genesis Node Program to onboard independent operators to run validation nodes during its initial rollout.
