Bitcoin for Developers

The two-day training "Bitcoin for Developers" focuses on technical aspects of the Bitcoin protocol and its implementation. Participants will learn to create applications using the Bitcoin network, work with wallets and transactions, and understand cryptocurrency security fundamentals.

Issues

Bitcoin architecture and protocol
Bitcoin transactions and scripts
Working with Bitcoin libraries (e.g., bitcoinjs, python-bitcoinlib)
Creating and managing Bitcoin wallets
Interaction with Bitcoin nodes and block explorers
Implementing Bitcoin payments in applications
Private key and wallet security
Bitcoin application testing (testnet, regtest)
Bitcoin scaling and Lightning Network

Benefits

Of technical aspects of Bitcoin protocol
Ability to create applications using the Bitcoin network
Knowledge of best practices in cryptocurrency application programming
Awareness of security aspects when working with Bitcoin

Who is this training for?

Programmers interested in blockchain technology

Cryptocurrency application developers

Software engineers wanting to expand their Bitcoin knowledge

Cryptocurrency enthusiasts with programming skills

Prerequisites

Programming experience (preferred languages: Python, JavaScript, or C++)
Basic knowledge of blockchain and cryptocurrency concepts

Training program

Bitcoin protocol architecture — blocks, chain, Merkle tree, proof-of-work, consensus rules, network topology (full nodes, SPV, miners)
UTXO model — Unspent Transaction Outputs vs account model (Ethereum), transaction structure (inputs, outputs, locktime, version)
Bitcoin Script — stack-based language, standard script types (P2PKH, P2SH, P2WPKH, P2WSH, P2TR), multisig, timelock (CLTV, CSV)
Cryptography in Bitcoin — ECDSA (secp256k1), Schnorr signatures (BIP340), addresses (Base58Check, Bech32, Bech32m), hashing (SHA-256, RIPEMD-160)
HD wallets — BIP32 (hierarchical deterministic), BIP39 (mnemonic), BIP44 (multi-account), derivation paths, master seed
Workshop: creating and signing transactions programmatically (bitcoinjs-lib / python-bitcoinlib), working with testnet

Bitcoin Core RPC — node configuration, JSON-RPC API, most important commands (getblock, getrawtransaction, sendrawtransaction, estimatesmartfee)
Working with libraries — bitcoinjs-lib (JavaScript), python-bitcoinlib (Python), rust-bitcoin — creating wallets, broadcasting transactions
Lightning Network — payment channels, HTLC, routing, invoice (BOLT11), LND/CLN API, channel opening/closing
Private key security — cold storage, HSM, key management, backup strategies, common vulnerabilities
Testing and environments — testnet, signet, regtest, local network simulation, automated testing
Workshop: Lightning payment implementation (LND REST API), building a simple block explorer, integration with application
