# A Blockchain-Based, Public, & Dependable System Blockchains have grown in a number of kinds over the last several years, depending on their architecture and setup. Depending on how the blockchain is set and how it is anticipated to accomplish the intended business purpose, the material stored on the blocks of the blockchain as well as the actions conducted by the various participants on the blockchain networks can be regulated. The two most popular types of blockchains are public and private blockchains. They are widely utilized by many cryptocurrency networks and individual businesses. Permissioned blockchains, a third kind, have also garnered interest. Anyone may join and participate in the blockchain network's essential operations in a public blockchain. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
