The calculation of the block size in Ethereum and its enforcement
As a prominent alternative to traditional blockchain technology, Ethereum has gained an immense popularity over the years with its decentralized financing applications (Defi), non-noticeable tokens (NFTS) and intelligent contracts. A decisive aspect of the scalability of Ethereum is the block size that determines the number of transactions that can be processed in each block. In this article, we will deal with the calculation of blocking in Ethereum and specifically examine the calculation process for enforcing the 1MB limit.
Ethereum’s block size calculation
The block size calculation in Ethereum is a complex process with several steps:
- Transaction number
: The first step is to count the number of transactions in each block. This is usually done by the iteration of all transactions that have been added to the block and save them in an array.
- Transaction Hashing : Then every transaction -Hash is used as the basis for the HASH calculation of the block.
- hash function
: A SHA-256-based hash function like the Keccak-256 algorithm is used to combine the hashes of the transactions into a single string called “block data”.
- Encryption and signature : The block data is encrypted with public-private key pairs and then signed by the account that has the transactions.
- Block-hash calculation : The encrypted block data are then once again lashed with the same SHA 256-based hash function, which leads to a new string called “Block Hash”.
Set enforcement of the 1MB limit
The block size calculation in Ethereum is intended to ensure that each block can have a maximum of 4 MB of data. To enforce this limit, two algorithms are used:
- Transaction -Hash length : The length of the hash of the individual transaction (typically 256 bit or 32 bytes) contributes to the total block size.
- Block data size : The number of transactions in the block also affects the size.
The block size calculation for Ethereum is using a combination of the following formulas:
Block_Size = (transaction_count * transaction_hash_length + block_data_size)
block_size = 4MB - (block_hash_length / 8)
Where block_size is the total block size, transaction_countis the number of transactions in the block, transaction_hash_lengthand block_data_sizeare constant that determine the contribution to the size of the block.
Comparison with Bitcoin Core
Bitcoin Core, a popular implementation of the Bitcoin protocol, also uses a similar calculation method to enforce its 1 MB limit. The main difference lies in the use of various hash functions and algorithms:
- Ethereum uses Hashing functions of SHA-256 like Keccak-256.
- Bitcoin Core uses SHA-256-based Hashinge functions such as Ripemd-160.
With regard to scalability, both implementations have their own strengths and weaknesses. While Bitcoin core can deal with higher transaction rates due to its ability to process more transactions per second, the block size of Ethereum for networks with high capacity with a focus on scalability is optimized.

In summary, it can be said that the calculation of the block size in Ethereum counts the number of transactions, inhibits it using a SHA-256-based algorithm and the encryption and signature of each transaction. To enforce the 1 -MM limit, two algorithms are used: Transaction -Hash length and block data size. The formulablock_size = (transaction_count * transaction_hash_lth + block_data_size)` determines the total block size based on these factors.
The Ethereum team continues to work towards improving scalability and performance by examining new solutions such as Sharding and Layer -2 -2 scaling technologies. As for the Bitcoin core, its developers want to increase the capacity of the network and at the same time maintain a balance between security and efficiency.
