Justin Sun says Tron’s post-quantum cryptography has gone live on testnet

TRON users and builders following the network can see that a post-quantum version has already been put on testnet, and that makes the test environment the place to watch next. The immediate change is that the project is no longer describing this work only as future planning; it is presented as live on testnet and ready for a mainnet move. (per cointelegraph.com)

In practice, what changes is that a mainnet switch is described as something TRON could do at any time, while what stays the same is that no launch date has been given. That means the status is a testnet rollout with mainnet timing still unset, rather than a completed mainnet deployment.

TRONTRX the event is about this asset

The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.
