How Often Do Blocks Get Added to The Bitcoin Blockchain?

The Bitcoin network automatically adjusts how difficult it is to find new blocks by increasing or decreasing the difficulty every 2,016 blocks for roughly two weeks. This ensures that there is 14 days’ worth of transaction data across the network before any given 2016-block period starts earning miners their first reward for creating new blocks. After this period ends and another set of 2,016 blocks have been created, the difficulty is adjusted again based on what happened during those first two weeks’ worth of mining activity.

The Bitcoin block time is 10 minutes.

This prevents double spending, allowing someone to spend the same coins more than once. If a transaction were broadcasted to all nodes and confirmed by them within 1 minute, it would be enough time for an attacker to clone their wallet and spend the same coins before they are confirmed. Because of this, blocks must be added at regular intervals so that if one tries to double-spend their bitcoins (or any other digital asset), they will not be able to do so successfully.

The first difficult adjustment happens after the 2016 blocks.

This is because the initial mining period is not expected to take exactly 10 minutes, so it’s best to wait until things are settled before making any changes. The next difficulty adjustment happens approximately every two weeks (14 days). 

At this time, the entire Bitcoin network adjusts along with block times and rewards based on how quickly miners could find a new block within those two weeks. If they found blocks faster than expected, the difficulty decreased. Suppose they found blocks slower than expected, and the difficulty increases. Usually, these adjustments are made automatically by bitcoin client software like Bitcoin Core. Then compares this information against historical data compiled by third parties. 

The second difficult adjustment happens after another 2016 block.

This is how it works:

  • The system adjusts the difficulty of every 2016 block to keep the average time between block creations (known as the “block time”) at 10 minutes.
  • We have 14,208 total blocks on the chain, so there are roughly 220 hours left before block number 212024 hits. That means there are about 220 hours left until we see our next difficulty adjustment take effect.
  • The average number of transactions per block is between 1,800 and 2,100. The average block size is approximately 1 megabyte.

To be accepted by the network, transactions must be packed together in a block. The miner who creates a block gets paid with bitcoin, created out of thin air by the miners and added to circulation by the system itself.

The amount of money paid as a reward for each block depends on how much data it contains. This means that blocks containing more transactions will accrue more fees than blocks with fewer transactions.

A block can include up to 2,016 transactions because of the way bitcoin transactions are structured and how much space each transaction takes up. Each transaction is made up of multiple inputs and outputs. The inputs represent the sender’s addresses, and the output represents the receiver’s address. And they all fit into one single line on the blockchain ledger. The number of transactions included in each block depends on its size and fee.

If your transaction has a low fee, it will likely not be included in any particular block unless you wait some time for that amount to increase or decrease. It depends on how many people want their payments processed by miners so that they can receive their funds faster than everyone else.


The Bitcoin blockchain is a powerful tool that you can use to send and receive money anywhere in the world. It’s decentralized, meaning there is no one central authority that controls it. Instead, transactions are recorded on a public ledger that anyone can access. This system makes it resistant to censorship or interference from governments or banks, who may want some control over how we use our money.
