What is Shardeum?

Shardeum is attempting to solve the trilemma affecting most blockchains where they have to prioritize among scalability, security and decentralization, but at best they can pick only two of these attributes.

Shardeum is employing a technique called sharding that partitions the network into shards, resulting in more transactions being processed, verified and validated in parallel. The startup’s blockchain, which is currently in testnet, aims to be EVM-compatible and use proof-of-stake and proof-of-quorum consensus mechanisms to reduce the cost of running the network and rely on three types of nodes — validator, archival and standby — in its network.

Shardeum anticipates that it will be able to process more than 100,000 transactions per second with 100,000 nodes and will maintain a latency of 10 seconds. The L1 blockchain will also provide ways to help Ethereum developers transition to Shardeum and maintain stable gas fees.
