Permissionless
Commonly used term to describe open source blockchain projects anyone can download freely and operate absent any restrictions imposed by a centralized authority. Permissionless blockchains are often referred to as public projects because their transactions are validated via a network open to examine by users.
Critical aspects of being permissionless include:
- Decentralization – consensus on the state of the network is agreed upon by the network’s nodes
- Censorship Resistance – Anyone can transact on the network with the same terms as everyone else
- Transparency – Records are accessible publicly
- Anonymity – No KYC terms required for network access
Operating a Bitcoin node is an example of permissionlessness. Anyone can start operating a Bitcoin node anytime, from anywhere. Operating the node grants them full access to its history and this access cannot be censored by any third parties.
