Welcome to cryptomarketblog, number one blog for crypto education. Here we explain the topics of cryptocurrency using examples so that anyone can easily understand them. In this article we are going to show you how run the Shardeum Sphinx betanet node to get eligible for Shardeum Airdrop.

Shardeum is an EVM-based, linearly scalable smart contract platform that provides low gas fees forever while maintaining true decentralization and solid security through dynamic state sharding.

Shardeum has confirmed to launch its own token $SHM and hinted of doing an airdrop. They reserved 5% off total supply to Ecosystem / Airdrops and 51% node mining. There is speculation that who runs Shardeum Sphinx Betanet Node may get an airdrop after they launch the token.
