What is a Blockchain service?
Blockchain as a Service is a unique model that allows consumers to use the cloud-based services to develop, use and host their blockchain apps, functions and smart contracts. In a nutshell, they provide full-fledged blockchain platforms that ease the development process.

A blockchain is a digital record of transactions. The name comes from its structure, in which individual records, called blocks, are linked together in single list, called a chain. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. By design, a blockchain is resistant to modification of the data.

Blockchains are a fascinating new technology. They enable fully decentralized databases, resistant to censorship and potentially allowing for system adoption in critical applications like money and identity.
