TRON DAO has set a year-end target for completing a quantum-resistant network upgrade, advancing its effort to protect the blockchain against cryptographic risks from future quantum computers. In an official announcement, the organization said the network is building toward quantum-resistant security as a long-term infrastructure priority, rather than responding to an immediate attack against its existing cryptography.
The timeline follows earlier testing of post-quantum signatures on TRON’s Nile testnet. The project’s TIP-899 specification introduces support for FN-DSA-512, based on Falcon-512, and ML-DSA-44, derived from Dilithium. The two signature schemes are designed to operate alongside existing ECDSA rather than requiring every account to migrate immediately.
TRON is building for the long term.

TRON Already Tests Two Post-Quantum Signatures
TRON activated FN-DSA-512 on Nile after a July governance proposal, with the test implementation covering transaction signatures, Super Representative block signatures, peer-to-peer handshakes and verification inside the TRON Virtual Machine. ML-DSA-44 has also been implemented as an alternative within the broader technical design. The testnet work means the year-end objective is backed by working protocol code, although mainnet deployment has not yet been completed.
The two algorithms involve different trade-offs. FN-DSA-512 offers smaller signatures, making it more attractive where transaction size matters, while ML-DSA-44 provides a standardized fallback. The National Institute of Standards and Technology (NIST) finalized ML-DSA under FIPS 204 in 2024 and describes it as a digital-signature standard designed to remain secure even against adversaries with large-scale quantum computers. That gives TRON one option built around an already finalized federal post-quantum standard.
FN-DSA remains at a different stage of standardization, while TRON’s own specification acknowledges that larger post-quantum keys and signatures can significantly increase transaction size. TIP-899 estimates that widespread use could reduce theoretical throughput unless later optimizations are introduced. Quantum resistance therefore creates an engineering trade-off between stronger future-proofing and higher bandwidth and storage requirements.
Mainnet Migration Details Remain Open
The precise path to full mainnet deployment has not yet been finalized publicly. TRON’s current design allows post-quantum and conventional ECDSA signatures to coexist, reducing the need for an immediate network-wide account migration. That compatibility could make adoption more gradual, but wallet support, validator configuration and performance under real mainnet load still require further validation.
The quantum threat itself also remains prospective. NIST’s post-quantum cryptography program says cryptographically relevant quantum computers may still be years or decades away, but migration should begin early because replacing widely deployed public-key cryptography can take many years. TRON’s upgrade should therefore be viewed as preparation for a future cryptographic risk, not evidence that current quantum machines can already compromise the network.
TRON has moved beyond a conceptual roadmap by deploying post-quantum signature support on its testnet and setting a year-end objective for the broader network. The key milestone will be whether that tested architecture reaches mainnet with acceptable performance, compatibility and security guarantees before 2026 closes.
