Block size

The complexity of contracts is based on the block size where the block size

is specified in bytes being run in Ethereum, and the maximum gas limit per

block will vary from block to block.

The basic payment of ETH from one account to another has a complexity of

21K gas, which means in Ethereum, the maximum block size is 1,5 00K

Gas, i.e., 1,5 00K / 21K enables 7 0 transactions to fit into a block and getting

1,5 00 to 2,000 transactions per block in the blockchain.

Block creation method for difficulty adjustment

The meaning of the difficulty adj ustment for block creation is the logic used

in Ethereum to keep the mining time of the blocks between 10 and 19

seconds. The difference of 0 to 9 seconds attracts geth to increase the
