Here is a comprehensive article about Ethereum and using bitcoin titles instead of public keys:
Why do you use Bitcoin titles instead of Ethereum’s public keys?
Ethereum, one of the most popular blockchain platforms, uses Bitcoin titles to manage transactions instead of public keys. While public keys are usually used in cryptographic systems such as RSA and elliptical curve cryptography (ECC), they have restrictions on safe communication and digital signatures. In this article, we examine why Ethereum has decided to use Bitcoin titles and what benefits it offers.
Why hash twice the public key?
A traditional public key cryptography is used to use a public key to encrypt the message and the encrypted message is then cleared (or digitally signed) before being sent or stored. This process ensures that only the desired recipient can decrypt the message. However, when using bitcoin titles in Ethereum, the process is slightly different.
In order to subtract the public key twice, we need to take two cryptographic steps:
- Cut the public key : Bitcoin’s title is cut through a one-way function, such as the SHA-256 function. This creates a fixed size byte string known as “hash” or “message digestion”.
- Application with a private key : Hash produced in step 1 is then encrypted (or digitally signed) with a private key to the Bitcoin title owner. This creates a new message that includes both the hash and the signature.
Security Benefits
Using Bitcoin titles offers a number of security benefits instead of public keys:
* Uniqueness : Each bitcoin has a unique identifier that makes it difficult to find out or copy.
* No crack : Using a private key to sign messages, Ethereum ensures that the sender does not deny the message. This is not reduced.
* Prevention of Dual Editions : Bitcoin titles are much harder for the attacker to spend the same bitcoin twice.
Do you have security in withdrawing from public keys?
To withdraw from public keys can provide certain security benefits:
* Decreased vulnerability : Using a single ID (bitcoin address), we reduce the number of potential vulnerabilities.
* Improved scalability : Less to size the network with less titles and manage more transactions.
At the same time, there are also disadvantages of withdrawing from public keys. For example:
* Increased complexity : Managing multiple bitcoin addresses can be complex and may be prone to error.
* Difficulty in recovering lost data : If a private key is lost or at risk, it may be difficult to recover all related devices (ie bitcoin).
The representations are more than one thing
Bitcoin titles are designed to depict more than one thing:
* Unique IDs : Each address has a unique ID (64 string).
* Transaction Data : Addresses may contain additional information about the transaction, such as the public key of the sender or recipient.
Using bitcoin titles, Ethereum allows more efficient and flexible digital signatures. The security benefits of withdrawal from public keys are significant, but it is essential that these benefits are considered to be possible to draw the possible disadvantages when planning the cryptographic system.
Conclusion
Using Ethereum Bitcoin titles instead of public keys is a deliberate design choice that provides many security benefits. Although there are some disadvantages that need to be taken into account, the benefits in many cases exceed the disadvantages. As more and more users are experimenting with Ethereum, we can expect their cryptographic architecture to develop and improve over time.
