Justin Sun: TRON launches post-quantum upgrade initiative

TRON will start building toward quantum-resistant cryptography, announced founder Justin Sun. The network follows Ethereum in preparing for real quantum developments and potential security flaws. 

TRON is preparing to release a new technical roadmap on quantum resistance. The project’s founder announced TRON’s post-quantum initiative. As Cryptopolitan reported, quantum projects are again in focus, as expectations grow that they may deliver viable tools even earlier than predicted. 

Quantum security is currently in its theoretical stage, but TRON aims for NIST-approved post-quantum cryptography, announced Justin Sun.

While Bitcoin debates whether to freeze vulnerable coins and Ethereum forms research committees, TRON is building.

Today I’m announcing that TRON is officially launching its post-quantum upgrade initiative. TRON will be the first major public blockchain to deploy…

The announcement arrives amid Bitcoin’s own debate for quantum-resistant upgrades. 

TRON currently secures over $5B in value, with an additional $86.7B in stablecoins from the growing USDT supply. Quantum resistance may preserve the chain’s position as a secure destination in the long run. 

The plan to introduce a post-quantum roadmap follows Ethereum’s decision to evolve the network. The Ethereum Foundation has already identified stress points, such as heavier post-quantum signatures, which may challenge the scalability efforts to date.

Will TRON preserve its high speed? 

Quantum-resistant cryptography has not been attempted on any live network. As with Ethereum, TRON will face the challenge of heavier signatures, around 10 to 121 times larger than the currently standard elliptic cryptography. 

TRON is currently one of the fastest and busiest networks, with minimal gas fees and high speed. Switching to a new type of signatures will pose serious challenges of scaling and preserving that speed. 

The biggest challenge for existing networks would be the eventual migration to quantum-resistant addresses. TRON hosts one of the largest collections of USDT addresses, and will have to switch signatures while ensuring value preservation and a simple user experience. 

How will quantum computing affect TRON? 

The challenges for TRON are similar to those of EVM networks, starting with validators. Quantum cryptography researchers state that each smart contract would be vulnerable to quantum hacking. 

Specifically, the TRON USDT smart contract uses multisig access with admin keys. Other contracts, such as wrapped BTC on TRON, also hold significant value and may be open to quantum attack. 

The advantage of TRON is that it only has 27 validators that have to reach consensus, and they may upgrade much faster compared to nodes on Bitcoin or Ethereum. 

Quantum upgrades will also not be a one-time process, and protocols may have to upgrade algorithms multiple times, with different types of quantum attacks. Despite the difficulty, TRON may become a first mover if the upgrade is successful. 

Wallets, apps, and other on-chain tools may also have to upgrade to protect their own weak signature points.
