Types of Blockchain Technologies
Blockchain technology can be categorized into several types: public blockchains, which are open to all; private/consortium blockchains, restricted to specific groups; semi-private blockchains, which have both public and private elements; sidechains, which are linked to a main blockchain like Bitcoin; and permissioned ledgers, where participants are trusted. Blockchain's applications extend beyond cryptocurrencies to various fields, indicating its potential to transform data storage and management in the future.
