The role of Merkle’s roots in verifying Ethereum transactions
When it comes to checking transactions at Blockchain Ethereum, one of the main components is the Merkle root. In this article, we will plunge the reason each block stores a root of Merkle and how miners use these roots to check the transactions.
What is a root of Merkle?
A root of Merkle is an algorithmic combination of multiple Merkle trees, which are data structures that represent transaction hash values or blocks. This allows efficient storage and recovery of large amounts of data without requiring a complete copy of data to be stored in blockchain.
How do miners check transactions using Merkle roots?
To verify a transaction, miners need to ensure that it is in accordance with the rules described in the Ethereum Virtual Machine (EVM) guidelines. Here are 18 conditions that check a transaction and why they depend on Merkle’s roots:
- Transaction Signature
: The miner verifies if the transaction has a valid signature using the ECDSA algorithm.
- Transaction data : The miner verifies if the transaction data is consistent with the rules described in the EVM guidelines.
3.
- Block Signature : The miner checks if the block has a valid signature using the ECDSA algorithm.
- Block Data : The miner verifies if the block data is consistent with the rules described in the EVM guidelines.
6.
- Hash Block: The miner checks if the block has a valid hash using the Sha-256 algorithm.
- Data Counting and Data Length : The miner verifies if the number of transactions in the block corresponds to the expected value and that each transaction is within the allowed limit (1-8 bytes for transaction hashes).
- Transaction and Displacement Index : The miner verifies if the transaction rates and compensation correspond to the expected values.
10.
- Block header check : The miner checks if the block header meets all the EVM guidelines, including the inclusion of the necessary metadata and the validation of the transaction.
- Signature Verification : The miner verifies if the signatures in the block correspond to the expected signature using the ECDSA algorithm.
- Data integrity : The miner verifies if the data in each transaction is consistent with the rules described in the EVM guidelines.
- Transaction Order : The miner ensures that the transactions are ordered correctly, according to the EVM guidelines.
- Consistency between the blocks : the miner verifies if there are any inconsistency or anomalies between the blocks.
- Block header consistency
: The miner checks if all block headers meet all EVM guidelines.

Conclusion
The use of Merkle roots in verifying Ethereum transactions provides a robust and efficient way to ensure the validity of transactions in blockchain. By trusting these roots, miners can quickly and accurately check transactions without having to store or recover large amounts of data. This is just one of the many reasons why Merkle’s roots play such an important role in maintaining the integrity and safety of the Ethereum network.
