Recently, someone asked who ADA is, so I might as well talk about the Ada coin project. To be honest, in the cryptocurrency world, Cardano is considered the most "academic" one, and its native token is ADA.

If you want to know the story behind ADA, you have to start with its founder, Charles Hoskinson. This guy was one of the co-founders of Ethereum, but later, due to ideological differences, he decided to create his own project. Cardano is his new project, and he has been researching it since 2015, over ten years now.

Interestingly, Cardano took a completely different path from the start. Unlike many coins that boast about revolutionizing the world right away, Cardano emphasizes "slow and steady"—first publishing academic papers, achieving scholarly results, and then gradually deploying the code. It claims to be the third-generation blockchain, with Bitcoin as the first generation (decentralized currency), Ethereum as the second (smart contracts), and Cardano aims to be a safer, more sustainable, and scalable next generation.

On the technical side, ADA uses the Ouroboros consensus mechanism (named after the serpent in Greek mythology that bites its tail), which is essentially a proof-of-stake (PoS) system. It consumes much less energy than Bitcoin mining and is more scientifically sound than early PoS schemes. As for the name ADA, it is said to honor Ada Lovelace, a mathematician from the 19th century, widely recognized as the world’s first programmer.

Now, Cardano has already launched smart contracts (with the Alonzo upgrade), supporting applications like NFTs, DeFi, and stablecoins. However, to be honest, the ADA ecosystem still lags behind Ethereum, which is a common criticism.

The pros and cons are quite clear. The advantages are that the code is very rigorous, backed by academic research, and the community is relatively rational; the disadvantages are slow development, slow application deployment, and sometimes the academic approach can be a bit heavy. If you think other coins are too impulsive and want to find a blockchain project that feels like scientists doing research, ADA and Cardano might be your choice. Currently, ADA is priced around $0.25, with a 24-hour increase of about +0.97%.
