Here is a comprehensive article on Ethereum and its use in Bitcoin addresses, not public keys:
** Why are you using Bitcoin addresses instead of public keys to Ethereum?
Ethereum, one of the most popular blockchain platforms using Bitcoin addresses, not public keys to manage transactions. While public keys are commonly used in cryptographic systems, such as RSA and elliptical curve cryptography (ECC), they have their own limitations when it comes to secure communication and digital signatures. In this article, we will explore why Ethereum chose to use Bitcoin addresses and what benefits it offers.
Why is there a public key twice?
In the traditional public key cryptography, a public key is used for encryption of the report, and the encrypted report is then mixed (or digitally signed) before sending or storing. This process ensures that the message can only be deciphered by the intended recipient. However, with the Ethereum of Bitcoin addresses, the process is slightly different.
We need to take two cryptographic steps twice:
1 Public key mixing : Bitcoin address is mixed using one-way function such as Sha-256. This creates a fixed -sized byte string known as “hash” or “digest report”.
Signing with a private key : 1st step produced has been encrypted (or digitally signed) using the appropriate Bitcoin address private key. This creates a new message that has both hash and signature.
Security Benefits
Using Bitcoin address instead of public keys offers several security benefits:
* Uniqueness : Each Bitcoin address has a unique identifier that makes it difficult to mention or duplicate addresses.
* Non -release : Using private key messages for signing, Ethereum ensures that the sender cannot deny send the message. It is known as non -compliance.
* Double Spending Prevention : It is much harder for the attacker to spend the same bitcoin twice with Bitcoin addresses.
** Is there a security abstract from public keys?
Abstract away from public keys can give some security benefits:
* Reduced vulnerability : Using a single identifier (Bitcoin address), we reduce the number of vulnerabilities.
* Improved scalability : Less addresses are easier to scale network and process more transactions.
However, abstracting from public keys also has its disadvantages. For example:
* Increased complexity : Managing multiple Bitcoin address can be complex and subject to errors.
* Difficulties in recovering lost data
: If a private key is lost or endangered, it may become difficult to recover all related assets (i.e., Bitcoin).
Representations of several things
Bitcoin addresses are designed to display several things:
* Unique identifiers : Each address has a unique identifier (64 characters).
* Date of Deal : Addresses may contain additional information about the transaction, such as the sender or the recipient’s public key.
Using Bitcoin addresses, Ethereum allows for more efficient and flexible digital signatures. The security benefits related to abstraction of public keys are important, but when developing a cryptographic system, it is important to weigh these advantages against possible disadvantages.
Conclusion
Ethereum uses Bitcoin addresses rather than a public key instead of a deliberate design choice that provides heavy security benefits. Although there are some disadvantages to consider, the advantages in many cases exceed the disadvantages. As more and more users and developers are experimenting with Ethereum, we can expect its cryptographic architecture to develop and improve over time.
