TRON Targets Quantum-Resistant Network Upgrade by Year-End

• TRON targets a quantum-resistant network upgrade by the end of 2026.
• Developers are testing Falcon- and Dilithium-based signatures on Nile.
• Growing stablecoin activity increases the importance of stronger network security.

TRON founder Justin Sun says the network aims to complete its quantum-resistant upgrade by the end of 2026.

Sun announced the target on Aug. 27 at the Bitcoin Asia 2026 conference in Hong Kong, highlighting growing concerns around quantum computing.

TRON Advances Quantum-Resistant Development

TRON has spent the past year developing technology designed to protect blockchain accounts from future quantum computing threats. Accordingly, the network introduced a quantum-resistant address solution during the first half of 2026.

The solution has already reached TRON’s testnet, allowing developers to evaluate its performance before any broader deployment.

However, the year-end target extends an earlier timeline announced by Sun in April for the network’s mainnet transition. At that time, TRON targeted a quantum-resistant testnet during the second quarter and mainnet implementation during the third quarter.

The testnet phase arrived in July, while the latest announcement moves the broader network upgrade beyond September.

Meanwhile, TRON developers have tested two post-quantum signature schemes through the Nile testnet implementation released in July. These include FN-DSA-512, derived from Falcon-512, alongside ML-DSA-44, derived from Dilithium. FN-DSA-512 serves as the default signature scheme, while ML-DSA-44 remains available as an alternative option.

Notably, post-quantum wallets currently lack gas-free transfers, seed-phrase recovery, and Ledger hardware wallet integration.

Those limitations could require further development before quantum-resistant accounts become suitable for wider network adoption.

Stablecoin Activity Raises Security Stakes

The upgrade carries significance because TRON supports substantial stablecoin activity across its blockchain ecosystem.

Sun said stablecoin issuance on TRON reached approximately $94 billion last week, with the figure expected to surpass $100 billion this year. Earlier reporting placed TRON’s second-quarter stablecoin settlement volume at approximately $2.08 trillion, underscoring the network’s financial importance.

Therefore, protecting transaction signatures becomes increasingly important as more stablecoin value moves through TRON-based infrastructure.

Quantum-resistant cryptography seeks to address the possibility that sufficiently powerful quantum computers could eventually compromise widely used elliptic-curve signatures.

Sun also urged the Bitcoin community to accelerate discussions around similar protections, although decentralized governance could make coordination difficult. 

He noted that miners, exchanges, WBTC participants, and other stakeholders would need to coordinate before Bitcoin could adopt broader quantum-resistant measures. The comments indicate that quantum security is becoming a wider industry concern rather than an issue limited to individual blockchain networks.

For TRON, completing the planned upgrade will depend on testing, compatibility, wallet support, and the final implementation process.
