Friends, I would like to know what is the fastest blockchain at the moment. I heard about the Tectum blockchain but there is very little information about them. Please kindly share your opinion.
There are plenty of altcoins claiming to have fast and very fast block times. You can ask in altcoin discussion.
Just keep in mind that:
* some of those may not have actual blockchain at all
* some of those may not be decentralized at all
* the exchanges usually just ask for a much higher number of confirmations for such transactions, hence you don't save any time
* it's not advised to accept those coins without a "healthy" number of confirmations
