Frequently Asked Questions

What is blockchain?

A blockchain is a shared, append-only ledger replicated across many participants, where each block links cryptographically to the previous one so records are difficult to alter.

What is a smart contract?

A program stored on a blockchain that runs automatically when its conditions are met, written in languages such as Solidity.

What is blockchain as a service?

A cloud offering that provisions and manages blockchain networks so teams can build applications without running the infrastructure.

What is asset tokenization?

Representing rights to a real-world asset, such as property or bonds, as digital tokens on a blockchain.

Public or enterprise blockchain?

Public chains such as Ethereum are open to anyone; enterprise platforms such as Hyperledger Fabric and Corda restrict participation and are built for business use.
