[53] It has been argued that permissioned blockchains can guarantee a certain level of decentralization, if carefully designed, as opposed to permissionless blockchains, which are often centralized in practice. The technology behind Bitcoins is the Blockchain Network. A)Blockchain enables users to verify that data tampering has not occurred. Since each block contains information about the previous block, they effectively form a chain (compare linked list data structure), with each additional block linking to the ones before it. [28], Sometimes separate blocks can be produced concurrently, creating a temporary fork.
