Smart Contracts are the incarnation of the Ultimate Open Source Micro Services. Their code is public. You could execute them – independently. Actually – anyone that has some coins for the Blockchain could.
Smart Contracts in the eyes of Web 2.0
You expose services in the older world of technologies through REST Endpoints. Ethereum has JSON-RPC. Other, newer optnios to offer a service are with
- SDKs,
- CLI
- and other developer tools to get things done.
Security of the Micro Services
As I’ve pointed out – Security is the same old pain – point in the new Web3.0 world. You’ve got to restrict who could execute a smart contract with Crypto – User Authentication. If your web 3.0 app could be executed by anyone – it must have been tested a lot. You should handle use and edge ases by many test users – on the test-net.
Scalability of Micro Services out of the box
With Old Micro Services – scalability comes thanks to the possibility to just clone stateless nodes horizontally
You could scale with Web3 automatically – with the number of blockchain nodes that are always live and online. Besides that, they are located all around the world. This speeds up the smart contracts micro services by having instances close to the users. People forget that even with the greatest technology, it takes time for the bytes to fly over the internet.
