Ethereum: How does Chaum style e-cash work? (all the Wiki links are broken)

I can give you an article on Chauze’s style electronic cash depending on my research and online resources available. Please note that certain links may not be active or accurate given the changes in the internet landscape.

Chauma E-Cash: Decentralized Digital Currency

In the 1990s, computer scientist Timothy C. Shaum introduced a new approach to a digital currency known as E-Cash (Ecash). Cham E-Cash was designed as a decentralized, anonymous and secure payment form that could be used without the need for intermediaries such as banks or credit card companies.

How E-See style works

The Chaua E-Cash system is based on a cryptographic technique and a unique concept called “blind signatures”. Here’s how it works:

1
The transmitter : E-Cash transmitter creates a digital marker that can be considered a good digital to denote the value of the currency unit.

• Serial number : Each serial number is assigned to a specific transmitter and is unique to this individual. This guarantees that there are no tokens or good doubles.

3
Digital Signature : The transmitter generates a random and irreversible digital signature for each serial number using a cryptographic technique called “Chaum Digital Signature Scheme” (CDSS). This signature is used to prove the identity and authenticity of the marker transmitter.

• Encryption : Each serial number is encrypted by a secret key known only by the transmitter.

• Blind Signature : Then the digital signature is combined with a encrypted serial number, creating a new unique identifier. This identifier is called “Ecash” or “good temporary”. Ecash is now anonymous and cannot be linked to a certain transaction or account.

Blind signature process

Here’s how a blind signature process works:

1
Deal : The user proposes the transaction indicating the amount of currency he wants to send.

• Serial Number : The user provides his serial number within the transaction.

3
Digital Signature : The transaction generates the digital signature of the transaction using the digital signature scheme of the chaographer (CDSS) and the crypt with the secret key.

• Blind Signature : The digital signature is combined with a encrypted serial number to create anonymous ECASH and cannot be linked to a certain transaction or account.

Security features

Chaua style e-cash has several security features that make it resistant to counterfeiting and censorship:

1
Anonymous : Each Ecash is unique and cannot be linked to a certain transaction or account.

• without cross -country

  : The digital signature guarantees that it cannot be changed, which makes it impossible to follow the origin of the transaction.

3
Safe key management : The secret key used for encryption is stored in a secret, ensuring that it can only be accessed by the individual who generated Ecash.

Conclusion

The E-Class of Cham-style is a decentralized digital currency that combines anonymity, security and transparency. Thus, the unique blind signature process ensures that transactions are safe and privately, making it an attractive opportunity for those looking for a more private payment format. Although the original Chauze e-money system has been replaced by new technologies such as Bitcoin, its concepts are still topical and inspiring.
