Just like all software, smart contracts on the blockchain are subject to serious security vulnerabilities and coding errors. The fact however that smart contracts are often directly in charge of assets and cannot be changed once they are on the blockchain, makes secure development and running essential. Some smart contract platforms have their own languages, for example Solidity in Ethereum. Bugs...

The internet was originally created as a platform to communicate freely, but it soon became a place where people could be monitored, controlled, and censored. 98% of content on the internet is deleted every 20 years.

Today, half of the internet is built on top of Amazon S3. Although the cloud has allowed Internet applications to scale, centralized infrastructure means less control over one's own data.

Skynet builds on Sia and enables web applicati...

Decentralized exchanges have been around for some time, and various designs have been attempted.
