Privacy

E-Cash is making a comeback in the Bitcoin ecosystem through protocols like Cashu and Fedimint. At its core lies an older idea: enabling digital payments that are as private as physical cash, without exposing every transaction to a public ledger or a centralized intermediary.

Bitcoin was designed as a robust monetary system, but with intentionally limited capacity. To address these constraints, several solutions have emerged to improve its usability. Among them, the Liquid Network takes a different approach: a sidechain focused on speed, privacy, and asset issuance.

Preserving privacy while accessing Bitcoin-collateralized loans is vital for digital sovereignty. This guide offers practical steps to use Lendasat privately, protecting identity, transaction history and on-chain activity.

Nostr is a truly decentralized protocol that serves as the foundation for a new kind of social network. Thanks to an innovative architecture, this protocol allows users to control their data and resist censorship, without relying on centralized servers. What Web3 promised but didn’t deliver, Nostr achieves. Discover how it works.

The Lightning Network is Bitcoin's payment layer, enabling instant, low-cost transactions without compromising decentralization. Discover why it exists, how it solves Bitcoin's scaling limits, and whether it is a viable long-term solution or just an intermediate step in Bitcoin's evolving monetary infrastructure.

Bitcoin was designed as a robust and decentralized monetary system, but its architecture naturally limits the complexity of applications built directly on its blockchain. For several years, different solutions have attempted to extend its capabilities without modifying its core rules. The RGB protocol follows this approach, with a radically different design: moving contract execution off-chain while preserving Bitcoin's security.

In this report, I explore the increasing use of Bitcoin by Iranians, a population facing economic challenges as well as censorship from their government and foreign powers. My goal is to depict how Bitcoin serves as a tool for protecting freedoms and preserving value in a complex economic and political context.
