Privacy vs Pseudonymity vs Anonymity

Privacy hides transaction details, pseudonymity hides real identity behind a public address, and anonymity makes actions unlinkable to any identity at all.

Proof of History

Proof of History is a cryptographic timekeeping method used by Solana to order transactions efficiently before they are processed by the network.

Solana

Solana is a high-performance blockchain designed for fast, low-cost transactions and scalable decentralized applications.

Permissionless vs Permissioned Blockchains

Permissionless blockchains are open to all users, while permissioned blockchains restrict access to approved participants for control and privacy.

Layer 0 Blockchain

Layer 0 blockchain is the underlying infrastructure that connects and supports multiple blockchains, enabling communication and interoperability between them.

Layer 1 Blockchain

Layer 1 blockchain is the base network of a blockchain system that processes transactions and provides security without relying on another chain.

Layer 2 Blockchain

Layer 2 blockchain is a secondary protocol built on top of a Layer 1 chain to improve scalability, reduce fees, and speed up transactions.

Layer 3 Blockchain

Layer 3 blockchain refers to application-level protocols built on top of Layer 1 and Layer 2, focusing on user-facing apps and interoperability between systems.

Blockchain Layers

Blockchain layers are the different levels of a blockchain ecosystem, typically including Layer 1 (base network), Layer 2 (scaling), and Layer 3 (applications).
