What Was eCash?
Let me tell you about eCash—it was a digital system designed for anonymous fund transfers. As a true pioneer in the world of cryptocurrency, its main aim was to protect the privacy of people making micropayments over the internet. I want you to know that eCash came to life in 1990, created by Dr. David Chaum through his company DigiCash, which he founded just a year earlier.
Even though big banks showed interest, eCash never really caught on, and DigiCash ended up filing for bankruptcy in 1998. Eventually, DigiCash and its eCash patents were sold off. Fast forward to 2018, and Chaum started a new cryptography-focused venture.
Understanding eCash
The concept for eCash originated with Dr. David Chaum back in the early 1980s. He was way ahead of his time, thinking about privacy issues in the emerging internet era. Not only did he push for privacy, but he built an anonymous payment system for the digital world—this was before the internet was even publicly available. In 1989, Chaum founded DigiCash to bring eCash to reality the next year.
At its heart, eCash relied on blind signatures. This is a digital signature method where the message content stays hidden before signing. That way, no one can connect a withdrawal to a spend transaction. The currency in the system was known as 'CyberBucks.'
eCash's Rise and Fall
DigiCash picked up steam in the mid-1990s as internet companies boomed. They secured deals with several banks planning to use the platform, including Deutsche Bank, Credit Suisse, and others worldwide. Microsoft even eyed eCash for Windows 95, but negotiations fell through.
The banks that adopted eCash tested it but never marketed it to customers as a full product. The only bank to actually deploy it was Mark Twain Bank in St. Louis, Missouri. Buyers got it for free, but sellers paid a transaction fee. They signed up about 5,000 customers, including over 300 merchants, yet it never built momentum. As Chaum put it, 'As the Web grew, the average level of sophistication of users dropped. It was hard to explain the importance of privacy to them.'
In the end, DigiCash filed for bankruptcy in 1998 and was sold to eCash Technologies, patents included. The eCash trademark now belongs to Due Inc., founded in 2015 and ranked among the top 10 e-wallets globally.
eCash and Online Security Today
Even after DigiCash and eCash failed, online security remains a critical concern in the digital space. Your financial data on computers, devices, or the cloud is at risk from hackers. Cryptocurrencies are huge now, and they trace their roots back to eCash. Bitcoin, the most famous one, launched in 2009 by an anonymous creator and quickly gained traction. Many see Dr. Chaum as the father of digital currency.
In 2018, Chaum introduced Elixxir, a network for anonymous communication controlled by users to safeguard their data—unlike today's systems where companies access and monetize user info for ads.
Was eCash the First Cryptocurrency?
Yes, it was. Created by David Chaum's DigiCash in 1990.
What Are Other Cryptocurrencies Before Bitcoin?
Before Bitcoin, there were eCash, B-money, Bit Gold, and Hashcash—all influential in Bitcoin's development.
What Was the First Blockchain?
David Chaum proposed a blockchain-like protocol in his 1982 dissertation, but the first decentralized blockchain was conceptualized by Satoshi Nakamoto in 2008.
The Bottom Line
eCash was envisioned by David Chaum in 1982 as an electronic cash system and brought to life in 1990 via DigiCash. It ran as a micropayment system at Mark Twain Bank from 1995 to 1998, until bankruptcy hit. The company and its eCash patents were sold to eCash Technologies.
