This is a new public chain that combines high concurrency, high compatibility and dual-token model.

Gnoland adopts a new language called Gnolang, which is a fork of Golang. Golang has clear advantages over other languages ​​when dealing with concurrency. While most programming languages ​​like C++ or Java use multithreading to run concurrent programs, Go uses Goroutines.

Multithreading is running multiple threads in parallel in a single process. This could be your browser playing music and running a search engine at the same time, or your word processor displaying your input while checking grammar.  
The problem with multithreading is that it requires context switching, where the operating system scheduler manages switching between processes and threads. This often results in overhead and consumes excessive resources.  
Goroutines, on the other hand, take the burden off the operating system by implementing a runtime local scheduler, the Go Scheduler.  
The creation and destruction of goroutines seems to consume less memory (as low as 0.2% of threads) and fully utilize all cores of the hardware.

Almost all existing blockchains are single-threaded, which means that processing multiple transactions at the same time will result in double spends or conflicts between states.  
Gnoland provides the most feasible solution for this, which is to integrate goroutines by supporting Golang as a smart contract language.  
The most commonly used languages ​​in the current blockchain development environment are Solidity for EVM compatible networks and Rust for Solana and Cosmos SDK networks;  
Both Solidity and Rust are inspired by C++. While the above are excellent languages, Gnolang inherits Golang’s faster compilation speed, cleaner syntax, and resource-efficient concurrency.
