The previously highly anticipated Bitcoin halving was completed on the evening of April 20, but the impact of the Bitcoin halving is still concerning. Bitcoin halving refers to an event where the reward for mining a new block is cut in half, meaning the Bitcoin received by miners to verify transactions is reduced by 50%. Many beginnersare currently wonderinghow many Bitcoins are there in one Bitcoin block after the halving? It is understood that before the halving, the reward for a block was 6.25 Bitcoins. After the halving, the current reward for a Bitcoin block is 3.125 Bitcoins. Next, the editor will tell you in detail.
How many Bitcoins are there in a Bitcoin block? There are currently 
3.125
Bitcoins in one Bitcoin block, and the reward for one Bitcoin block will continue to be halved according to Bitcoin’s halving rules. According to the current halving rule, Bitcoin’s block reward will be halved every approximately four years. When Bitcoin reaches its maximum number of
21 million, no new Bitcoins will be issued, even though that number ends up being just under 21 million. Bitcoin transactions will continue to be aggregated into blocks for processing, and Bitcoin miners will continue to receive rewards, but likely only transaction processing fees. Bitcoin miners will be affected when 21 million coins are reached, but the exact extent will depend on the development of Bitcoin as a cryptocurrency. In some future scenarios, Bitcoin miners may still be able to make money solely from transaction processing. Even with lower transaction volume and lost block rewards, miners can still make money if Bitcoin is used primarily as a store of value rather than as a daily purchase in 2140. To process high-value transactions or high-volume transactions, miners can increase transaction fees. More efficient "second layer" blockchains, such as the Lightning Network, work alongside the Bitcoin blockchain to make it easier for users to spend Bitcoin in their daily lives. How many transactions can a Bitcoin block contain? One Bitcoin block can hold about
4,000 transactions, and the capacity limit of each block of the Bitcoin network is
1MB. Since each Bitcoin transaction is different in size, the number of transactions that can fit into a block will also vary. Generally speaking, the size of an ordinary Bitcoin transaction is about 200-300 bytes, but it can be larger. Assuming that the capacity of a block is 1MB and the size of a transaction is 250 bytes, the block can accommodate approximately 4,000 transactions (1,000,000 bytes ÷ 250 bytes/transaction). This is only a rough estimate, and the actual situation will be affected by other factors, such as transaction complexity, handling fees, and network congestion. Since there is a transaction confirmation process in the Bitcoin network, the transaction confirmation time also has a certain relationship with the block size. When there are a large number of transactions in the Bitcoin network, transaction confirmation time may become longer because transactions need to wait to be included in a block before they can be confirmed. And when the number of transactions in the Bitcoin network is smaller, the transaction confirmation time may be shorter. As the number of Bitcoin users and transaction volume increases, the 1MB block size limit may cause transaction congestion and delays. In order to solve this problem, the Bitcoin network has introduced technologies such as Segregated Witness and Lightning Network to improve transaction processing capabilities and confirmation speed.
