TRON network has enabled post-quantum cryptographic signatures on its Nile testnet, deploying two NIST-standardized algorithms to strengthen the network against future threats from quantum computing.

Tron network becomes one of the first blockchain networks to actively upgrade its native cryptographic foundations to keep up with the growing threat of quantum computing. In an X post, the Tron network announced the release of GreatVoyage-v4.8.2-PQ1-build1 on the Nile testnet.

The build introduces support for two post-quantum signature schemes: Falcon-512 and ML-DSA-44. Both signature schemes are drawn from the cryptographic standards finalized by the U.S. National Institute of Standards and Technology (NIST).

According to the announcement, the upgrade will apply to transaction signatures, super representative block production signatures, P2P fast-forward node handshakes, and TVM contract signature verification.

In June, the TRON network processed 385.77 million transactions and logged 26.97 million active addresses, both all-time highs. The circulating USDT on TRON also topped $86 billion last month, more than on any other blockchain.

Justin Sun says Tron network will be quantum resistant

Justin Sun cited TRON DAO’s statement, saying that the TRON network will be the first quantum-resistant network. He argued that post-quantum security is the primary demand of the AI era. He cited decryption risks as a reason the shift is unavoidable for any major blockchain.

Many public blockchains today, including TRON, rely on the Elliptic Curve Digital Signature Algorithm (ECDSA) over the secp256k1 curve, the same cryptographic foundation Bitcoin uses.

However, the crypto research community is concerned that a sufficiently powerful, quantum computer running Shor’s algorithm can theoretically derive a private key from a public key. This can break the fundamental security assumption that safeguards wallet ownership on every major chain.

TRON network has deployed on its testnet, Falcon-512 and ML-DSA-44, which are designed to resist attacks from future quantum computers that are powerful enough to break current elliptic-curve cryptography. Falcon relies on lattice-based mathematics, while ML-DSA-44 is a variant of CRYSTALS-Dilithium, another NIST-selected scheme.

The TRON network testnet build is a mandatory upgrade for Nile testnet nodes, but the new features do not activate automatically. They require a separate governance proposal to go through TRON’s on-chain committee process before any transition to the mainnet can proceed.

Networks adjust to quantum threats

Ethereum Foundation developers launched a Post-Quantum Ethereum website in March 2026, with Layer 1 protocol upgrades projected to finish by 2029. Similarly, the Solana Foundation has already gone a step further by deploying post-quantum digital signatures on its own testnet.

Outside the chain layer, Coinbase CEO Brian Armstrong announced in January 2026 an independent advisory board dedicated to quantum computing and blockchain security. Google has set its own 2029 target for migrating its infrastructure to post-quantum cryptography.
