The main concept of ICON is their idea of a “loopchain.” As stated in their whitepaper, a loopchain can be described as a “high-performance blockchain that can provide real-time transaction, which is based on enhanced Smart Contract.” Through ICON, participants will be able to connect to any blockchain without relying on the current centralized exchanges.
EOS is also the first blockchain with a constitution. There are governing principles that every stakeholder agrees on, and the set of rules is attached to every block that is mined. EOS will have the capability to process millions of transactions each second using horizontal scaling. This is much different from Bitcoin and Ethereum. The current model also allows for 5 percent inflation, which can be used to further develop the network. In addition, EOS does not require users to pay for each transaction, which will help fuel adoption.
In 1983, the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash.[7][8] Later, in 1995, he implemented it through Digicash,[9] an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or any third party.
