Question - rate limit guard?

[ohaddahan]

Is there a plan for rate limiting guard?

Not sure if needed , since the bot tax has been quite successful in reducing spam.

If it's needed , I can open a PR.
Plan is, having a PDA used as a mini blockchain.

As in, client reads PDA data and pass that to minting instruction.

The program will compare PDA data to client input and hash this data with a nonce from client or clock time, and update the PDA.

This means that only one can mint until the network propagates the new state and clients can pass the correct PDA info again.

Can also be expanded to store an array of size X if a higher throughput is desired.

Interesting. Perhaps this could be a time-based one, so it is more predictable. Like, you are allowed to mint one every 30 seconds. So the PDA would have the timestamp of the last mint transaction of the user and a new mint will only be allowed if the difference between the last transaction time and the clock time is over a certain limit.

Yeah time limit also possible, simpler and easier to config specific rate.
Can just allow specific number of mints per time interval.
Will update my PR accordingly.
