The Bitcoin block is a file that records information about network transactions. If we consider the blockchain as a large office, it is a page block from the blockchain office. Here we want to look at the size of the blocks and why they are important.
What is the use of blockchain in the network?
The blocks are connected like the rings of a chain. Blockchain transactions are confirmed by miners before they can be added to the Bitcoin network as new information. The size of the block limits the number of transactions that can be verified within it. If a block has more than its transaction size, it will not be approved by the network.
What is the size of the block?
At the beginning of Bitcoin, the size of each block was limited to 36 MB. But on July 14, 2010, the size of the blocks was reduced to one megabyte in response to threats from spam transactions that slowed down the network. Shortly after the blocks were reduced to one megabyte, there was talk of increasing them. Because the amount of network transactions in the future may exceed the available volume of blocks.
Why is block size important?
The size of a block means the limit on the number of transactions that the Bitcoin network can process per second. In a way, it’s limiting bitcoin scalability. As the blocks fill up, the network becomes crowded. Then transaction fees increase. Network congestion and blockchain size to the point of limitation raise concerns about slowing down transaction processing and rising fees. This could marginalize the purpose and uses of Bitcoin. Even higher fees can cause bitcoin to become obsolete as a means of trading.
Why is it necessary to increase the size of the blocks?
To reduce fees, process more transactions per second, and increase the scalability of Bitcoin, the size of the blocks must be increased. “If the number of network transactions increases too much, we will have a saturated network,” says Gavin Andersen. Of course, this will not happen. “Because people are reluctant to use bitcoin because of unreliable transactions.”
What is Segwit?
There were several plans to increase the size of the block, one of which was Segovit. Segwit is a process in which the capacity of a block to store information increases. but how? By deleting the signature information from the Bitcoin transaction. When specific sections of a transaction are removed, the block capacity for storing more information increases. Despite the sequence, each byte of information occupies only a quarter of the block. As a result, data entry in the block is quadrupled.
