Tron's quantum-resistant signatures still need governance approval to leave the Nile testnet

Sun's post went up about 100 days after Nile switched on ^[17]. "We're closely tracking progress in quantum computing and AI, and we're ready to bring quantum resistance to mainnet at any time," Sun said in a post on X ^[2]. Sun can vouch for the code, but the date belongs to Tron's governance bodies, whose separate approvals mainnet activation still needs, according to Crypto Briefing ^[8]. Neither report says when a mainnet proposal will reach them.

The next few months can run several ways. A quick approval lets Tron make a year-end goal that was 82 days away on the day Sun posted ^[18]. An approval followed by thin uptake would put the capability on mainnet with little of the chain's value behind it ^[13]. And if Nile's throughput and storage results on the larger signatures slow the approval ^[13], the slip lengthens; it began when the testnet went live two days after the second quarter it was scheduled for had closed ^[19].

We think the governance approval is the next gate anyone can check, and the smaller of two; the larger one is uptake. Tron processes hundreds of millions of transactions a month and holds tens of billions of dollars in stablecoin value ^[12], and an approval moves none of those balances onto a post-quantum key by itself. The counter-case is strongest at the validator layer (or rather, at the parts of it the sources describe). On Nile the new signatures already reach block production and peer-to-peer handshakes between nodes ^[6], so a mainnet proposal that made them mandatory there would cover consensus whatever wallet holders do. In that case we would be wrong about blocks, if not about balances. For now Crypto Briefing describes every part of the Nile version as opt-in ^[7].

Tron's plan leaves existing wallets working as they always have ^[7], so the work of migrating falls to each holder who decides to switch. AmericanFortress has proposed a scheme that skips that step, adding post-quantum protection without users moving funds, rotating keys or changing addresses, Cointelegraph reported ^[16]. The paper is on the Cryptography ePrint Archive and had not been peer-reviewed ^[16].
