Study Notes
Bitcoin Mining and Reward Structure
- Genesis Block mined in January 2009 with a reward of 50 Bitcoins.
- Mining reward halves every 210,000 Blocks, approximately every four years.
- First halving occurred in November 2012, reducing the reward to 25 Bitcoins.
- Latest halving projected for April 2024 will further reduce the reward to 3.125 Bitcoins.
- The final halving (32nd) expected in the 2130s, with the last Bitcoin to be mined around 2140.
- By 2022, 90% of Bitcoin supply mined; 99% expected by 2030 with remaining 1% distributed over the following century.
Bitcoin Issuance Schedule
- First cycle (Jan 2009 - Nov 2012): 50 Bitcoins reward; 10.5 million issued (50%).
- Second cycle (Nov 2012 - Jul 2016): 25 Bitcoins reward; 5.25 million issued (75%).
- Third cycle (Jul 2016 - May 2020): 12.5 Bitcoins reward; 2.625 million issued (88%).
- Fourth cycle (May 2020 - Apr 2024): 6.25 Bitcoins reward; 1.3125 million issued (94%).
- Subsequent cycles continue with diminishing rewards until complete issuance.
Mining and Difficulty Adjustment
- Any entity can mine Bitcoin; competition leads to frequent block generation.
- Difficulty Adjustment mechanism ensures uniform issuance, maintaining consistent mining intervals.
- If block generation is too easy, excessive Bitcoin is produced; too hard results in slow transactions.
Impact of Geographic and Technological Factors
- 2021 China banned crypto mining, removing about 25% of global mining capacity.
- Reduction in miners initially lowered Difficulty Adjustment by a third; subsequent recovery occurred.
- Bitcoin mining not location-dependent, but heavily reliant on electricity costs.
Transaction Validation and Node Role
- Bitcoin Miners compile transaction lists and compete through energy usage to post to Blockchain.
- Nodes, consisting of both miners and holders, validate transactions through consensus.
- Need for altruism among nodes emphasized, with potential concerns about incentives for continued operation.
Altruism and Network Integrity
- Satoshi warned in 2015 about reliance on the altruism of nodes; incentives may be necessary.
- Nodes perform less "work" compared to miners, but their validation is crucial for Ledger integrity.
- Altruistic dynamics parallel industry bodies updating and enforcing standards.
Focus on Transactions over Account Balances
- The Bitcoin network’s emphasis lies in transaction integrity rather than individual account balances, shaping its operational ethos.
