Lightweight blockchain

Simplified distributed ledger technology

A lightweight blockchain is a simplified blockchain enabling trustless, secure data transactions between nodes.[1] A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes.[2] To ensure each new block of data added to the chain is legitimate, a consensus mechanism must be used; for example, the Bitcoin blockchain uses Proof-of-Work (PoW) and the Ethereum blockchain uses Proof-of-Stake (PoS). The architecture of this blockchain-based distributed ledger technology requires intensive energy consumption and computational power.

Though lightweight blockchains are simplified, they do not sacrifice on data security,[3] making them suitable for applications and devices that need data reliability but limited computational resources.[4] For example, Internet of Things (IoT)[5] devices or Autonomous Vehicles.[6]

Lightweight blockchain-based devices can have various use-cases. A recent experiment proved that a lightweight blockchain-based network could accommodate up to 1.34 million authentication processes every second, which is more than sufficient to be applied in a resource-constrained IoT network [7] or the health sector.[8]
