# 6. Incentive By convention, the first transaction in a block is a special transaction that starts a new coin owned by the creator of the block. This adds an incentive for nodes to support the network, and provides a way to initially distribute coins into circulation, since there is no central authority to issue them. The steady addition of a constant amount of new coins is analogous to gold miners expending resources to add gold to circulation. In our case, it is CPU time and electricity that is expended. > 💡 In plain terms > This is the block reward — more commonly known as "mining." > > When a miner successfully solves the proof-of-work puzzle and adds a block, they are allowed to include a special first transaction that sends newly created bitcoin directly to themselves. No one signs off on this. > The rules of the protocol allow it, and all other nodes accept it. > > This is how all bitcoin ever enters existence. > There is no central bank printing money. There is no company distributing coins. > New bitcoin is issued to whoever contributes the computational work to secure the network. Work → reward. No work → no reward. > > Satoshi compared it to gold mining: gold miners spend energy to dig gold out of the ground, adding it to the world's supply. Bitcoin miners spend electricity to solve puzzles, adding new coins to the network's supply. The incentive can also be funded with transaction fees. If the output value of a transaction is less than its input value, the difference is a transaction fee that is added to the incentive value of the block containing the transaction. Once a predetermined number of coins have entered circulation, the incentive can transition entirely to transaction fees and be completely inflation free. > 💡 In plain terms > Bitcoin has a fixed cap of 21 million coins. > As the block reward decreases over time (it halves roughly every 4 years in an event called "the halving"), miners will increasingly be compensated through transaction fees instead. > > When you send bitcoin, you can optionally attach a small fee. > Miners prioritize transactions with higher fees — so the fee market ensures the network stays motivated to process your transaction even after the last coin is mined, which will happen around the year 2140. > > The monetary policy is written into the code and cannot be changed without the agreement of the entire network. The incentive may help encourage nodes to stay honest. If a greedy attacker is able to assemble more CPU power than all the honest nodes, he would have to choose between using it to defraud people by stealing back his payments, or using it to generate new coins. He ought to find it more profitable to play by the rules, such rules that favour him with more new coins than everyone else combined, than to undermine the system and the validity of his own wealth. > 💡 In plain terms > This is one of Bitcoin's most elegant insights — a game theory argument. > > Suppose someone spends billions of dollars on mining hardware to control > 51% of the network. They could theoretically rewrite recent transactions. > But why would they? > > With that much computing power, they could instead earn more bitcoin legally through block rewards and fees than they'd gain through fraud — and without destroying the value of the very asset they're trying to steal. > Attacking Bitcoin would crash its price, making their own holdings worthless. > > Honesty is more profitable than cheating. > The incentives are designed so that the rational choice and the honest choice are the same choice. > ⚡ Why It Works vs. Traditional Finance > Central banks control money supply with discretionary policy — committees decide how much money to print, and that decision is opaque and politically influenced. > History is full of examples of currency debasement through overprinting. > > Bitcoin's issuance schedule is fixed in code: > - Total supply: exactly 21 million BTC, ever > - Issuance rate: halves every ~210,000 blocks (~4 years) > - No committee, no discretion, no exceptions > > No government, no company, and no individual can create more Bitcoin beyond the schedule. This makes Bitcoin the first monetary system in history with a fully auditable, predictable, and tamper-proof supply curve.
