ADA is enabling smart contracts in June this year, the testnet has already started, they never tried before as they were in another era of the roadmap focused on decentralization.
So what is so special to ADA in that regard? because usually the new smart contract will always be busy talking about at first,
even though after that it will disappear over time.
I did not say it was special I was just clarifying that they did not try to enable smart contract before, their roadmap progress is quite slow and they explain that by making sure that the network is scalable, decentralized and fees are not high. Being a leader-based POS like EOS some could argue that Cardano is not 100% decentralized but this comes with advantages, speed and low fees. Once the platform is running DApps we will see if the low fees will attract application developers. I am not saying that Cardano is special or better then other blockchains though however I do think it's worth it to follow their development.
