Minimal dice/coin BIP39 seed-ceremony + independent address-verification device (CYD/MicroPython)

Offline Bitcoin address-collision research toolkit and Go benchmark for P2PKH, Hash160, secp256k1, SHA-256, RIPEMD-160, and brute-force infeasibility demos.

🧠 Bitcoin Base58 Inspector | 💻 CLI + 🌐 Flask Web UI | 🔐 RIPEMD-160 decoding, ✅ checksum validation, 📊 entropy analysis.

A real-time intelligence panel for Bitcoin’s network health — exposing mempool dynamics, client diversity, hash-phase shifts, and the signals that protect decentralization and strengthen the chain’s security.

Live map of your Bitcoin Core node's peers across the world with internet service provider (ISP) diversity breakdown. Real-time IP geolocation via included database and automatic lookups. Peer tools, mempool stats, live BTC price, and zero-config auto-detection.

Small scripts to try a bruteforce of the richest Bitcoin addresses

Security-audit research code for the deterministic Yasmarang RNG in Coldcard hardware wallets (Mk2/Mk3/Mk4/Q/Mk5)

A decentralized protocol enabling STX token staking, earning analytics tokens, and engaging in tiered governance for protocol decision-making on the Stacks blockchain.

Crypto wallet security guide: an interactive do/don't trainer for seed phrase safety, a wallet self-audit with score, and a safe inventory of your wallets and accounts (names and types only — never keys). Free local account, works as guest.

Experimental research linking prime-number positional sequences with BIP-39 entropy, mnemonic generation and Bitcoin wallet security. Python generators, checksum analysis, Native SegWit tools and reproducible documentation.

Free, open-source Bitcoin self-custody documentation. Device setup guides, backup checklists, and inheritance planning. Community-maintained.

Coldcard Bitcoin Wallet brings together secure Bitcoin cold storage, air-gapped transaction signing, deterministic RNG audit research, BIP39 seed workflows, backup guidance, and self-custody tools for Coldcard BTC users evaluating Coinkite hardware and offline wallet operations.
