Can someone please explain how they are doing this?
Travala is a token and not a coin, this means that it operates on the algorithm of the platform on which it is built upon, in this case; that platform is binance chain and the algorithm is PoSA (Proof Of Staked Authority)
Bitcoin on the other hand uses a PoW (Proof of Work) algorithm. This ensures all blocks are valid and provides hightened security as it is very expensive and non profitable to attempt an attack on the network. The solution to bitcoins
scalability issue is not to switch to another coin simply because they offer faster transactions, there are existing methods to make it much easier to transact in Bitcoin like LN, segwit, consolidating inputs etc, and there should be more in the future.
I think the solution is to switch to an alternative coin or a token, because the average person doesn’t know about lightning network, sending transactions with 0 fees and other ways to reduce network fees or increase speed. What is the point in hoping Bitcoin will be able to scale one day when you already got coins and tokens that have already solved the problem of scalability? And how could you possibly say PoW is secure than PoS? Because I don’t know any known way of PoS getting hacked?
PoSA is somewhat a hybrid of centralization and decentralization. You could say it is centralized decentralization. Who do you think the validators of AVA Token?
