How Google uses logic in machine learning
Similar to Proof-of-work, Proof-of-Stake is a consensus mechanism which underpins security of the blockchain by preventing doublespend.
In traditional Proof-of-Work based blockchains, miners maintain the integrity of the blockchain data by racing to solve computation-intensive, Proof-of-work mathematical puzzles in exchange for rewards. In this regard, they help validate transactions with their CPU power, and the more CPU power you have the proportionately larger your ability to influence the network is. In Proof-of-Stake, stakeholders vote with their “dollars” instead of computing power.

Blockchain rent is a solution that aims to reduce the amount of data that is stored on the network in order to help speed up transaction times.
With Ethereum, users pay for computational steps, memory, transaction logs, and permanent storage. While most of these are resour...

The basic premise here is that instead of nodes storing everything on the blockchain, they only store data that is more frequently requested locally and leave other data on the “cloud” via Swarm.

Currently, all blockchain consensus protocols (eg. Bitcoin, Ethereum, Ripple, Tendermint) have a challenging limitation: every fully participating node in the network must process every transaction. Recall that blockchains have one inherent critical characteristic — “decentraliza...
