Scalability is one of the biggest problems the crypto industry is facing today. The unprecedented growth the industry has seen has made using DeFi a slow, expensive, and risky endeavor that has been pushing users towards more centralized platforms.
And while Layer 2 networks emerged as a perfect solution to this problem, most of them have been designed as a method for damage control, rather than a complementary addition to a blockchain.
Cardano’s Layer 2 scalability solution was built before problems occurred
This, however, isn’t the case with Cardano (ADA). Its parent company IOHK took a different approach to expand the blockchain’s capacity—designing a Layer 2 scaling solution alongside the blockchain.
Its native scalability solution, called Hydra, was designed to address the biggest issues blockchain networks face when dealing with high throughput. Firstly, the network needs to strike a balance between setting fees low enough to satisfy its users and setting them high enough
