After some time the second generation of cryptocurrency was borne from the learning experience of digicash. One of the systems that tried to walk on the same path as digicash was e-gold.  E-gold was created by an oncologist named dough Jackson. E-gold’s currency was gold. It received physical gold as deposits from its users and in return, it issued e-gold or gold credit. E-gold was able to manage cross-border transactions using gold. But because of the prevalence of fraudulent investment scams like Ponzi schemes, e-gold was closed.

How cryptocurrency work

Cryptocurrency work on a distributed public ledger called blockchain. A blockchain is a chain of the block, each block contains information about transaction details, hash value (this is typically the id of the block), previous Hash (this keeps track of the previous block id), timestamp (when a block is created), and proof of work. Blockchain uses a peer-to-peer network that allows anyone to join. When someone joins this network, he gets a full copy of the blockchain.

When a transaction of cryptocurrency is made by someone it creates a new block. This new block validates by nodes on all copies of the blockchain. A node is simply a computer or device that is connected to the blockchain network. Each cryptocurrency has its network with a set of nodes communicating with each other to verify blocks. Each node has the authority to verify and validate all cryptocurrency transfers before they are appended to the chain.
