Om Darknet

The term was originally coined in the 1970s to designate networks which were isolated from ARPANET (which evolved into the Internet) for security purposes.

In a recent interview on the Unchained Podcast, Vitalik Buterin also indicated that a sharding mechanism may replace the need for Casper. The Larger The Stake, The Greater The Reward...

The heart of Bitcoin is the blockchain. This distributed ledger system is a dynamic and decentralized database that contains a list of all the Bitcoin transactions that have ever taken place. The list is continually updated with every new transaction that occurs and groups of transactions are built into small, chronological bundles called blocks. A transaction can’t be changed once it’s added to the list and it’s shared and stored on a massive network of devices called nodes. Node Diggity, Node Doubt Nodes maintain the database and validate transactions. When a transaction occurs, it’s broadcast from one node to...
