Go has gained popularity in the blockchain space for its performance, concurrency, and memory management features, making it a popular language for developing blockchain applications.
One of the most popular blockchain platforms built using Go is Hyperledger Fabric, an enterprise-grade blockchain framework that supports distributed ledger solutions for a wide range of industries, including finance, healthcare, supply chain, and more. Fabric leverages Go's concurrency model to handle multiple concurrent transactions and supports smart contracts written in Go.
Another popular blockchain platform built using Go is Cosmos, a decentralized network of independent parallel blockchains that can scale and interoperate with each other. Cosmos uses Go to implement its Tendermint consensus engine and supports the development of decentralized applications (dApps) in Go.
In addition to these platforms, there are many other blockchain projects built using Go, such as Ethereum's Go implementation (geth), the decentralized file storage system IPFS, and the Bitcoin full node implementation btcd.
Overall, Go's speed, concurrency, and memory management make it a popular choice for building high-performance blockchain applications.
