Bitcoin remains the undisputed “king” of blockchains. Bitcoin’s dominance has increased significantly since the experimental times of 2017. Bitcoin has survived many attempted forks and “civil wars” and has established itself as the reserve cryptocurrency; people fall back to Bitcoin in bear markets. The production network has stood the test of time for over 10 years now.
Blockchain, a decentralized ledger for linking information, can handle vast amounts of data and is often deemed immutable, as it is very difficult to alter completed digital entries. It underpins various cryptocurrencies, including the now-surging Bitcoin, and has become the cornerstone of Web 3.0 — the next, post-Big Tech phase in the evolution of the internet. Though many of its applications are in early developmental stages, blockchain is being used to innovate fields from banking and real estate to art and now, waste management.
