Concepts Overview
Core explanations of Bitcoin mechanisms, protocols, and foundational ideas, broken down so you can make informed decisions about your stack, from running a node to understanding privacy models.
Accessibility in Bitcoin
Guidance on designing and evaluating Bitcoin wallets, apps, and workflows for universal usability across visual, cognitive, auditory, motor, and temporary impairments.
AI and Bitcoin
Exploration of the intersection between artificial intelligence and Bitcoin, covering decentralized AI, Lightning payments for AI services, and the risks of AI centralization.
Bitcoin Address Types
Comparison of Bitcoin address formats including Legacy, P2SH, SegWit (Bech32), native SegWit, and Taproot, with guidance on which to use for compatibility, privacy, and future-proofing.
Bitcoin Education
Overview of Bitcoin education resources, curricula, and pedagogical approaches for developers, users, and educators across technical and non-technical audiences.
Bitcoin Node Types
Comparison of full, pruned, archival, Simplified Payment Verification (SPV), and neutral nodes; explains trade-offs in storage, trust, privacy, and validation guarantees.
Bitcoin Protocol
Survey of the Bitcoin protocol layer including consensus rules, peer-to-peer messaging, mempool policy, and the BIP process for proposing changes.
Chaumian Ecash
Explanation of Chaumian eCash principles, blind signatures, and modern implementations like Cashu and Fedimint for private, custodial or federated ecash on Bitcoin.
Circular Economy
Examination of earning, spending, and saving entirely in Bitcoin without converting to fiat, including merchant directories, gift cards, and peer-to-peer commerce tools.
Custody Models
Comparison of self-custody, multisig, collaborative custody, and custodial solutions with threat-model guidance for choosing the right approach.
Home Mining
Practical guide to solo and pooled mining at home using consumer hardware, hash marketplaces, and Stratum V2 / DATUM template control.
Lightning Network
Overview of Lightning Network architecture, channel management, routing, Bolt 12 offers, and trade-offs versus on-chain and other Layer 2 solutions.
Mesh Networks
Survey of mesh networking projects (GoTenna, LoRaWAN, Reticulum) for Bitcoin transaction propagation and resilience in disconnected or censored environments.
Mining Payout Schemas
Comparison of PPLNS, FPPS, PPS+, TIDES, and solo mining payout models with variance, latency, and pool fee implications.
Multisig
Deep dive into n-of-m multisignature schemes, hardware wallet coordination, deterministic wallets (BIP-85), and popular multisig coordinators (Sparrow, Nunchuk, CARAVAN).
No-KYC Acquisition
Methods for acquiring Bitcoin without identity verification including Bisq, RoboSats, HodlHodl, Azteco vouchers, Bitcoin ATMs, and in-person trades.
Nostr
Introduction to the Nostr protocol for censorship-resistant social networking, including clients, relays, NIPs, and integration with Lightning via Zaps.
P2P Exchange
Comparison of peer-to-peer Bitcoin exchanges: Bisq, RoboSats, HodlHodl, LocalBitcoins (deprecated), and emerging decentralized order books.
Payjoin
Explanation of PayJoin (BIP-78) interactive transactions for improved on-chain privacy, wallet support, and coordination with receiver collaboration.
Privacy Stacks
Modular compositions of tools for on-chain, Lightning, and metadata privacy — including CoinJoin, Silent Payments, Tor, and Nostr/SSH isolation.
Proof of Work
Fundamentals of Nakamoto consensus, difficulty adjustment, hash rate measurement, energy economics, and the security model underlying Bitcoin's immutability.
UTXO Model
Explanation of the UTXO accounting model, coin selection, consolidation, dust limits, and how UTXO management affects privacy, fees, and wallet performance.
