The amount of the reward halves after the creation of every , blocks, or roughly every four years. The amount is expected to hit zero around Article Sources.

Bitcoin How Bitcoin Works. Bitcoin What Determines the Price of 1 Bitcoin? Investopedia is part of the Dotdash publishing family. Bank — A centralized entity who maintains and manages the payment system. Once the person initiates the transaction the bank banker verifies the ledger, authenticates the transaction, and then moves the amount from the account of person A to B.
In system like this only bank is responsible for the security and operation of the network as they are the only one controlling the entire payment network. However Bitcoin is different. Bitcoin is a peer to peer network; meaning the system is distributed and decentralized. There is no single or central authority controlling the Bitcoin network.
So who maintains the security of the Bitcoin network and who conducts the transaction here? In Bitcoin miners are the backbone of the entire network. Without them the whole system would be dysfunctional. They are responsible for the security of the network, issuing of new Bitcoins and conducting transactions. Person A creates the transaction, sign it using their private keys and broadcasts the transaction to the Bitcoin network.
Now it is miners duty to verify this transaction and add it to the ledger. Now again who are these miners? Miners are random people like you and me running Bitcoin software except with specialized computers mining equipments. In other words they are special nodes on the blockchain who are dedicated towards the operation of the network. So how is a random person allowed to confirm a Bitcoin transaction? The Bitcoin protocol is built on blockchain which is a growing list of records called blocks.
When you initiate a transaction miners pick your transaction along with several other transactions that has been broadcasted to the network. They then enclose the list of transactions in a block, verifies them and then add it to the Bitcoin blockchain.
In Bitcoin network roughly every 10 minutes a new block is created and each block contains a set of most recent transactions. It not only contains transaction information but a block also contains information specific to the blockchain such as: version, block id, hash of the previous block etc. Now coming to transaction validation: In Bitcoin there are certain transaction validation rules set which ensures that the coins are not spent already, verifies the transaction size, syntax etc.
Once the miner finds the transaction to be valid they then add it to a block but not yet allowed to submit the block to the network. Now before broadcasting a block to the network miners need to solve a cryptographic equation.
They are required to provide a Proof of Work solution. Anyways the following outline should give you a basic understanding. Now Proof of Work is a highly resource intensive task which requires a lots of computing power. Only those with enormous and efficient computational power will be able to solve the puzzle first. Once the miner finds the solution, their block will be validated by other miners and finally it gets added to the network.
Once the block gets accepted by the network miners compete against each other to produce the next block on the blockchain. Since this system is decentralized anybody can participate in the validation of the transaction.
However do note that mining is a highly intensive task. One needs a lots of electric and computational power in order to solve the mathematical problem. Since it requires lots of resource; to compensate the miners the winning miner will receive reward in the form of Bitcoins. These rewards are actually new coins which are being distributed to the network.
An incentive structure like this motivates miners to constantly validate the Bitcoin transactions on the network. Not only that but as more and more miners join the party, the difficulty rises which in turn keeps the network secure and ensures the blockchain is immutable. Hope it explains! Now here are some of the common questions related to Block rewards. In Bitcoin the Block Reward refers to the amount of new Bitcoins distributed by the network to the miners who solve each blocks.
Block rewards are the only way how new Bitcoins are created on the network. It operates both as an incentive mechanism as well as inflation mechanism. So how much is the block reward and who sets these rules? Not only block reward, but the total coin supply , the reward halving structure is all already coded in the software and is set by the creator of the Bitcoin, Satoshi Nakamoto. However Satoshi does not control Bitcoin. Bitcoin is an open source application meaning the software is free, publicly available and anyone can contribute to the code.
However none of the rules which are set can be changed without the consensus of the entire network. Initially the block reward of Bitcoin network was 50 BTC. However this is not constant. The block reward structure in Bitcoin is designed in such a way that it halves every , blocks. Since the block time of Bitcoin is 10 Minute; roughly every 4 years the block reward halving occurs. Currently as of March the block reward of Bitcoin is Every time a miner finds a new block they will receive a reward of So why diminish the block rewards?
