Blockchain is the technology behind cryptocurrencies. It is a decentralized, distributed ledger that records transactions in real time without the need of any central authority.
The way blockchain confirms transactions are through mining. The miners solve complex mathematical problems using sophisticated computer software to confirm transactions and add them to a public ledger, called the blockchain. The confirmed transaction will be added as a new “block” and the miner will be rewarded with a set amount of coins for his work.

What does block height mean?
Block height refers to the number of blocks in the blockchain. In other words, it is the number of blocks on a chain.
You can think of a “block” as a record of transactions taking place within a certain timeframe. A blockheight refers to how many of these records have been added since the previous block was recorded.
At regular intervals, blocks are added to the blockchain. As a result, the block height is a measure of how many blocks have been recorded on the blockchain before the current block.
Block height is useful when looking at what the transaction history of a particular cryptocurrency looks like. For example, you can look up bitcoin’s block height on sites such as BlockChain to see its entire transaction history.
What are some examples of block heights?
All cryptocurrencies have different block heights depending on their own unique blockchain sequences. To give you an idea of how block heights work, here are some examples:
Why is block height important?
Block height is important for a number of reasons:
- It’s integral to cryptocurrency mining and transactions, as it records how many blocks were added before a particular transaction was made. In other words, if you want to check whether a certain transaction has been confirmed by the network, you must look at the block height recorded on the blockchain.
- Block height is a critical milestone in cryptocurrency transactions. Once a transaction has been recorded at a particular block height, it cannot be reversed or tampered with.
- A higher block height often implies that the currency has more blocks on its blockchain, which means more mining power has been put into the network. As mining power increases, transactions are processed faster.
- Block height can be used to assess how long a cryptocurrency has been in existence and its progress over the years.
- The number of blocks confirming transactions on the blockchain also usually implies how secure and safe transactions are, as well (i.e., all confirmed transactions make it virtually impossible for hackers to alter existing records).
How do you calculate block height?
The height of the most recent block, or the highest block in the chain, is used to determine the block height of the blockchain. The current length of the blockchain minus one is used to determine block height.
Is Block Number the same as block height?
The block height refers to the most recent block that has been mined. The block number refers to any block up until and including the current block height.Jan
Genesis block is the first block of the blockchain. It is also known as the “Golden Block”. The genesis block contains information about when it was mined and by whom.
Block explorers are tools that let you search a specific block number/transactions/address in a blockchain. For example, if you have a Bitcoin wallet and know the block height of your first transaction, you can use a block explorer to search for it.
