Types of Blockchain Technologies
Blockchain technology can be categorized into several types: public blockchains, which are open to all; private or consortium blockchains, shared among a specific group; semi-private blockchains, which have both public and private components; sidechains, which are linked to a main blockchain like Bitcoin's Lightning Network; and permissioned ledgers, where trusted participants manage transactions. Blockchain's applications extend beyond cryptocurrency to areas like supply chain management, indicating its potential to transform data storage and management in various sectors.
