Justin Sun calls TRON the world’s first post-quantum attack-resistant network, with the mainnet going live in Q3 of 2026.

TRON founder Justin Sun posted on X on April 26 to announce that TRON plans to enable anti-quantum attack functionality on its testnet in Q2, with the mainnet rollout planned for Q3. In the post, Justin Sun described this upgrade plan as the “world’s first anti-quantum attack network.” Although quantum threats are still largely theoretical for now, Ethereum, Solana, and others have already published post-quantum cryptography (PQC) upgrade plans or timelines.

TRON Quantum-Safe Upgrade Timeline

According to Justin Sun’s public post on X, the key timeline for TRON’s quantum-safe upgrade is as follows:

2026 Q2: Enable anti-quantum attack functionality on the testnet

2026 Q3: Launch quantum-safe infrastructure on the mainnet

In the post, Justin Sun said that after the upgrade is completed, users’ funds on the network will remain safe even in the age of AI-driven development.

Justin Sun’s Public Position on Post-Quantum Security

According to Justin Sun’s statement on X, he said: “As the founder of a mainstream cryptocurrency, while we are focusing on the benefits brought by AI applications, we should also closely pay attention to the risks that AI development brings, and the decryption of quantum computing is the most core key.” In the same post, Justin Sun characterized post-quantum security as the “top requirement” in the AI era, and said that the risk of decryption from quantum computing is the core basis driving this upgrade.

Current Status of Post-Quantum Cryptography Upgrades in Mainstream Blockchains

According to publicly released updates from various organizations, as of April 2026, the progress in post-quantum cryptography among major blockchains and technology companies is as follows:

Ethereum Foundation: In March 2026, launch the official post-quantum Ethereum website; the target year for the L1 protocol upgrade is 2029, and a full migration of the execution layer is expected to still take several more years

Solana Foundation: Has deployed post-quantum digital signatures on the testnet

Coinbase: In January 2026, CEO Brian Armstrong announced the formation of an independent advisory committee on quantum computing and blockchain security

Google: In March 2026, it released a timeline for migrating post-quantum cryptography, with the target year being 2029

Frequently Asked Questions

Where did Justin Sun announce TRON’s quantum-safe upgrade plan, and what are the specific timeline milestones?

According to Justin Sun’s public post on X, TRON plans to enable anti-quantum attack functionality on its testnet in 2026 Q2 and roll out the mainnet in 2026 Q3. Justin Sun referred to it as the “world’s first anti-quantum attack network.”

What is Justin Sun’s core claim about post-quantum security?

According to Justin Sun’s statement on X, he believes that the decryption capability of quantum computing is the core risk brought by AI development. Post-quantum security is therefore the “top requirement” for encryption networks in the AI era, and also the main basis for TRON to carry out a quantum-safe upgrade.

What are the target timelines for post-quantum cryptography upgrades for Ethereum and Google?

According to the Ethereum Foundation’s public release, the target year for upgrading its L1 protocol is 2029, and a complete migration of the execution layer is expected to require additional several more years. According to Google’s public release in March 2026, the target year for migrating post-quantum cryptography is also 2029.
