Learn about Distributed Ledger Technology
Blockchain is a form of distributed ledger technology (DLT).
By distributing data across a network of computers, DLT allows any group of individuals to maintain a public, auditable ledger of cryptographically-secured transactions.
The result is a system capable of transforming global financial and organizational structures to better serve the public good.
Blockchain technology provides an unprecedented opportunity to fix some of the systemic issues stemming from centralized power in financial systems and on the Internet.
Types of Blockchains
Distributed ledgers can be categorized as either public or private and permissioned or permissionless.
Public vs Private
Public means anyone can view the transactions on a distributed ledger.
Private means that permission is required to participate in the network.
Permissioned vs Permissionless
Permissionless means anyone can run a node and help secure a distributed ledger.
Permissioned means permission must be given in order to run a node and help secure a distributed ledger.
