After mining 21 million bitcoins, can we randomly issue more? When asked by this brother about a teacher's statement on the internet that Bitcoin can be issued, I can only say to take a look. There is a misunderstanding in this statement: one ️⃣ The fixed total amount of Bitcoin is the core design of the code and protocol The total limit of 21 million Bitcoin coins is strictly set by Satoshi Nakamoto in the code, gradually releasing new coins through a "halving mechanism" until all coins are mined out by 2140. This mechanism is implemented through algorithms, where the reward is halved every 210000 blocks (approximately 4 years), and the final block reward approaches zero, with the total amount no longer increasing. 🔶 Technical immutability: The code of Bitcoin is open source, but modifying core parameters (such as the total amount) requires unanimous agreement from all network nodes and miners. Even if developers propose modifications, code updates cannot take effect without broad consensus. 🔶 Economic incentive binding: The interests of miners and holders are directly related to the scarcity of Bitcoin. The issuance will dilute the value of existing holders and undermine the foundation of trust, so the community generally opposes it. two ️⃣ Additional issuance requires consensus across the entire network, but there is significant resistance in practice The teacher mentioned that '51% of all nodes and miners agree to issue additional shares', but this viewpoint overlooks several key issues: 🔶 The complexity of consensus: The Bitcoin network is decentralized, and modifying core rules requires consensus from miners, developers, exchanges, users, and other parties. In history, even smaller protocol upgrades (such as block size adjustments) have caused community fragmentation (such as Bitcoin Cash forks). 🔶 Conflict of interest: Miners' main income comes from block rewards and transaction fees. If an additional issuance is made, it may increase block rewards in the short term, but in the long run it will lead to a decline in coin prices and a decrease in actual returns. Holders of coins will strongly oppose the issuance, as it directly damages the value of their assets. 🔶 Network security: If forced issuance leads to community fragmentation, Bitcoin's computing power may be dispersed, and network security may be weakened, further threatening the survival of the system. three ️⃣ The scarcity of Bitcoin is the basis of its value 🔶 Deflation model and trust mechanism: Bitcoin's fixed aggregate imitates the scarcity of gold, becoming its core value proposition in combating inflation. If an additional issuance is made, this characteristic will be disrupted, shaking the market's trust in Bitcoin. 🔶 Actual circulation is lower than theoretical value: Due to reasons such as private key loss and wallet damage, some bitcoins have been permanently withdrawn from circulation. It is estimated that the actual tradable volume will be much lower than 21 million pieces, further strengthening scarcity. four ️⃣ Historical Cases and Community Attitudes 🔶 The failure of the issuance proposal: In 2019, a developer proposed an issuance at the Satoshi Nakamoto Roundtable, but it was not pushed forward due to strong opposition from the community. Developer Peter Todd's idea of an "inflation hard fork" was also not adopted, reflecting the community's firm consensus on the total cap. 🔶 The existence of alternative solutions: If future miners' profits are insufficient (block rewards tend to zero), the Bitcoin network can maintain miner incentives by increasing transaction fees without the need for additional issuance. Finally, I would like to say This teacher's viewpoint is theoretically possible (the code can be modified), but its practical feasibility is extremely low The fixed total amount of Bitcoin is not only a technical rule, but also the cornerstone of community consensus and economic models. Additional issuance requires breaking through multiple barriers of technology, interests, and trust, and existing mechanisms such as fee replacement rewards have provided solutions for long-term network security. The total limit of 21 million for Bitcoin will remain unchanged in the foreseeable future.
