Governance, Layer 1 (L1)
eCash is a cryptocurrency project that was developed in the late 1990s by David Chaum, a cryptographer and computer scientist.
The goal of eCash was to create a digital currency that could be used for online payments without the need for a third-party intermediary. The system used cryptographic techniques to ensure that transactions were secure and anonymous. The eCash system worked by having users generate digital tokens, which could then be used to make payments.
These tokens were created using a combination of public key cryptography and zero-knowledge proofs, which allowed users to prove that they had the funds necessary for the transaction without revealing any other information about themselves or their accounts. The tokens were then sent to the recipient's address, where they could be redeemed for goods or services. The system also included an escrow service, which allowed users to set up contracts with each other and ensure that both parties fulfilled their obligations before releasing funds.
eCash was one of the first attempts at creating a digital currency, but it never gained widespread adoption due to its complexity and lack of trust in the technology at the time. Despite this, it laid the groundwork for many of today's cryptocurrencies, such as Bitcoin and Ethereum.
