Ethereum: Are all blockchain transactions stored on each client?

On the Ethereum blockchain, a transaction from one person to another is a complex process involving multiple steps and providers. While the Ethereum protocol was designed to be decentralized and secure, some explanations suggest that every blockchain client could know all transaction details.

Decentralization Theory

The main goal of blockchain decentralization is to reduce the dependency between clients and a single central provider. In a decentralized blockchain network, each client has access to all transactions that have been made before the request was received, thus ensuring greater transparency and security.

How ​​the protocol works

In the Ethereum system, each transaction is a small block that contains information such as the amount of Ether (ETC) transferred, the recipient’s address, and other additional data. These blocks are connected in a sequence to form a chain of confirmations called a “block”.

When a client asks its transaction provider (miner) for information about a specific transaction, the provider must verify the security and authenticity of the block before sending it to other clients. This is achieved by a combination of cryptography, HMAC (HMAC-based message authentication code) hashing, and other security algorithms.

How ​​do you know if all the data is stored on each client?

In theory, there is no clear way to know all the transaction data for a specific client. However, there are a few considerations:

• Hashes: Each block has a unique hash that identifies its place in the chain. This means that only the transaction provider can create a hash for a given block.

• Cryptography: Ethereum transactions use cryptography to ensure the authenticity and security of the data. The hash of each block is used as a password to verify its integrity.

Conclusion

While there is no clear way to know all the transaction details of a particular client, the Ethereum protocol was designed to be decentralized and secure. A combination of cryptography, hashing, and authentication ensures that each client has access to a secure confirmation chain that contains all the important information about the transactions they have made.

It is important to note that the Ethereum protocol has been adapting over time to improve security and scalability. However, it is very important to remember that you should always use the right security tools and protocols to protect your transactions and personal information.
