- Security and Risk Management
- Internal and external reconciliation required.
- No restrictions imposed by design.
- Single point of failure/control.
- Requires a middleman for transactions.
- Actions are performed on behalf of fund holders.
- No inherent backup protection.
- Transactions are trustless and verified via cryptographic proof.
- No central authority or middleman required.
- No single point of failure.
- Distributed consensus ensures network integrity.
- Immutable and transparent record of transactions.
- Medium of Exchange: Facilitates trade.
- Store of Value: Retains purchasing power over time.
- Unit of Account: Standard measurement for valuing goods/services.
- 2007 – Satoshi Nakamoto conceptualizes Bitcoin.
- 2008 – Bitcoin whitepaper released, addressing double-spending problem.
- 2009 – Bitcoin network launched, first transaction between Satoshi and Hal Finney.
- 2010 – First real-world Bitcoin transaction (10,000 BTC for pizza).
- 2011 – Bitcoin surpasses $1 USD; first Bitcoin price bubble.
- 2012 – Bitcoin Foundation formed to standardize protocol development.
- 2013 – Market cap surpasses $1 billion USD.
- Fixed Supply: 21 million BTC hard cap.
- Scarcity: Anything scarce can be money if people agree to use it.
- Mining Rewards: BTC supply halves roughly every four years.
- SHA-256 (Secure Hash Algorithm 256-bit) ensures security.
- One-way mathematical function: Input cannot be derived from output.
- More secure and used in digital signatures.
- Examples: SSL/TLS, Bitcoin addresses.
- Same key for encryption and decryption.
- Examples: AES, DES, Blowfish.
- Ensures non-repudiable transactions.
- Bitcoin wallets generate public/private key pairs.
- Transactions are signed with a private key and verified with a public key.
- Input: Sending address.
- Amount: BTC being transferred.
- Output: Receiving address.
- Fees: Incentive for miners to validate transactions.
- Verification: Miners confirm transactions before adding them to the blockchain.
- Public ledger of all Bitcoin transactions.
- Transactions are added in chronological order.
- Each block has a 1MB data limit.
- Adds transactions to the blockchain.
- Secures the network.
- Distributes new BTC through block rewards.
- SHA-256 Proof-of-Work (PoW).
- CPU Mining: Outdated.
- GPU Mining: More efficient but largely replaced.
- FPGA (Field Programmable Gate Array): Custom mining solutions.
- ASIC (Application-Specific Integrated Circuit): Industry standard, highly efficient.
- Pools: Frequent but smaller rewards, shared among miners.
- Solo: Less frequent but full block rewards.
- Web-Based Wallets (e.g., Exchange wallets).
- Paper Wallets (Offline storage).
- Hardware Wallets (e.g., Ledger, Trezor).
- Multi-Sig Wallets (Require multiple keys to authorize transactions).
- Hot Wallets (Connected to the internet, convenient but riskier).
- Cold Wallets (Offline storage, more secure).
- Generate multiple private keys from a single master seed.
- Improves security and refund capabilities.
- Users, Exchanges, Developers, Educators, Miners, Investors.
- Developers propose protocol changes, miners vote (~55% consensus needed).
- Provide a transparent view of all BTC transactions.
- If a miner or group controls >50% of network hash rate, they could:
- Prevent specific transactions.
- Reverse their own transactions.
- Block other miners from confirming transactions.
- Private keys should never be shared.
- Backup private keys securely.
- Use multi-signature wallets for added security.
- Represents BTC available to spend at an address.
