Blockchains can only handle a limited number of transactions per second.
However, experts generally agree that if this tech is to be more widely adopted there’s a core problem that needs solving.
It’s a complicated topic, but we can return to Bitcoin as an example of decentralized blockchain security.
In short, security is a fundamental requirement for a blockchain to be successful because, without it, attackers can take control of the chain, rendering it useless.
As mentioned, these blockchain transaction speeds are limited due to the way the information needs to be processed by the different participants that make up the decentralized network, and the nature of the PoW consensus mechanism itself.
So here lies the trilemma: given the connection between the desired properties of decentralization and security, the fundamental design of how blockchain works makes it hard to scale.
