Some client libraries provide convenience functions as well, beyond simple function execution. Apr 19, at Smart Contracts again, just blobs of code are executed by every single full node in the network , which is a lot of redundancy good but this costs a lot of energy and time bad. In order to reach wide adoption, though, a language and compiler must be thoroughly vetted and tested, which will take time. Once you start writing smart contracts, you end up doing a lot of the same things over and over again; compiling your source code to bytecode and an abi, deploying it to the network, testing the deployed contract, etc. Tickets are selling fast. Because so many engineers developing for Ethereum and other smart contract platforms are coming from web development, this concept might be new and crazy. By investing in terabytes of hard drive space, you buy yourself a better chance to create duplicate blocks and fork the system.

Using ETHPM, you can inherit from or link to other well-known contracts and libraries, reducing code duplication and ideally providing a strong foundation of good contracts for future development. The exploit occurred due to a now highly-recognized re-entrancy bug; a malicious contract could cause a non-infinite, recursive call to the contract, causing it to update internal state incorrectly. As we've seen, most of these alternative protocols employ some type of pay-to-play scheme. But it turns out that reading them is the fastest way to understand.
