Types of blockchain

Based on the way that blockchain has evolved over the last few years, it can be divided into multiple categories with distinct though sometimes partially-overlapping attributes. You should note that the tiers described earlier in the chapter are a different concept whereby the logical categorization of blockchain based on its evolution and usage is presented.

In this section, we will examine the different types of blockchains from a technical and business usage perspective. These blockchain types can occur on any blockchain tier, as there is no direct relationship between those tiers and the various types of blockchain.

In this section we'll examine:

• Distributed ledgers
• Distributed Ledger Technology (DLT)
• Blockchains
• Ledgers
