TRON Tests Post-Quantum Crypto, Wallet Plan Next
TRON’s post-quantum signature feature is now live on its Nile testnet, and founder Justin Sun has invited developers to begin building on it. Concurrently, AmericanFortress, a U.S. blockchain security firm, has proposed a method to make existing wallets quantum-resistant without requiring users to migrate addresses, rotate keys, or move funds. These developments come as Ethereum researcher Justin Drake warns that advancements in AI could compromise ECDSA wallet security sooner than many anticipate.
TRON’s Testnet Implementation
Sun announced that the capability went live on the testnet and that TRON can transition to the mainnet “at any time.” This rollout followed a governance vote on the Nile testnet, and the current build integrates a second standardized scheme in addition to the first.
- First algorithm: Falcon-512 (FN-DSA-512), activated on July 2, 2026, via Nile Committee Proposal No. 20628, according to Sun’s X post.
- Current build: Anaxagoras v4.8.2.3-PQ1, which adds ML-DSA-44.
- Standards: ML-DSA is the lattice signature scheme standardized as NIST FIPS 204; Falcon is NIST’s upcoming FN-DSA.
- Status: Currently on testnet, with no mainnet migration date announced.
- Scope: Provides quantum-resistant transaction signatures for developers building on Nile.
Both ML-DSA-44 and Falcon-512 aim to replace elliptic-curve signatures, which quantum computers could eventually compromise. TRON’s objective is to be among the first major networks to achieve quantum resistance before “Q-Day.”
The AmericanFortress Proposal
Meanwhile, AmericanFortress has released a cryptographic plan designed to add post-quantum protection to wallets without altering existing addresses, keys, or balances.
Many alternative proposals involve some form of account migration, which can be disruptive for users. The firm’s design circumvents this step, which presents a key advantage.
The paper, currently on the Cryptography ePrint Archive, hasn’t yet undergone peer review. This status distinguishes it as a promising engineering concept rather than independently validated cryptography.
The specific signature route it advocates for is also not yet definitively reported, which means whether it utilizes hash-based or lattice signatures will determine if it complements or competes with TRON’s approach.
The Intensifying Threat
Drake has cautioned that AI and mathematics could render ECDSA wallet security ineffective in months, not years. Custodians are already treating exposed public keys as a significant risk; BitGo, for instance, has implemented quantum-risk management controls for Bitcoin wallets.
Standardized post-quantum signing is also undergoing tests elsewhere, including an FIPS 204 ML-DSA implementation by TIP Protocol, which runs its public page in a simulated test mode.
