Introduces Ethereum-Style Publish-Subscribe Capabilities

Singapore – October 13, 2020 – PureStake, the company developing the Moonbeam smart contract platform, has released the latest version of its TestNet, Moonbase Alpha, and added new functionality that includes publish-subscribe support for the Web3 RPC. This marks the first significant upgrade and feature release since Moonbase Alpha was introduced three weeks ago.

Currently in active development, Moonbeam is a smart contract platform that aims to simplify the deployment process for Ethereum developers that want to expand to Polkadot. By minimizing the changes needed to run existing Solidity smart contracts on the new network, Ethereum projects can simply replicate their dApp and deploy it to Moonbeam using Truffle, Remix, and other popular developer tools.

The publish-subscribe functionality closes the last significant functional gap in Moonbeam creating an Ethereum-like environment. Commonly referred to as pub/sub, this messaging pattern makes it possible for dApps, like wallets and block explorers, to receive updates about on-chain transactions, balances, and other critical data without needing to issue new queries.

In total, the new functionality introduced in Moonbase Alpha v2 includes:

  • Event subscription support (pub/sub) in the Web3 RPC, which is commonly used by dApp developers
  • Support for pre-compiles including ecrecover, sha256, ripemd160, and the identity function
  • GPLv3 licenses

Moonbase Alpha was created purely for development purposes — it will continue to undergo development and enhancements from our engineering team. More information about Moonbase Alpha, including the currently available features and architecture, can be found on the project documentation site.

About the Moonbeam Network

Moonbeam is an Ethereum-compatible smart contract platform on the Polkadot network that makes it easy to build natively interoperable applications. This Ethereum compatibility allows developers to deploy existing Solidity smart contracts and DApp frontends to Moonbeam with minimal changes. As a parachain on the Polkadot network, Moonbeam will benefit from the shared security of the Polkadot relay chain and integrations with other chains that are connected to Polkadot. Currently in active development by PureStake, Moonbeam is expected to reach MainNet by early 2021. Learn more:
