I found a new decentralized web platform called the NEAR Protocol: https://nearprotocol.com/
“NEAR is a blockchain that allows you to build decentralized apps.”
I heard that they use sharded blockchains which may solve the performance problems with single blockchains.
NEAR could be useful as a computing and smart contract platform on top of the SAFE network. NEAR uses WebAssemply (WASM) which I believe has a huge future potential, not only in browsers but in also in IoT devices and even in backend computing.
I noticed that NEAR uses AssemblyScript, but today also C++ and Rust can be compiled into WASM, such as: https://www.rust-lang.org/what/wasm
