What is a consensus algorithm?

There is only one state of truth in a blockchain. But how can we make sure the state of truth doesn’t get tampered with? Consensus algorithms are protocols that nodes use to agree with each other on the one and only state of truth in the blockchain. In this video, we explain to you the definition of consensus algorithms and how they work. In this video, we answer:

– What is the consensus algorithm?
– What are the benefits and what are the limitations?
– What types of consensus algorithms are available?
– What are the best options?

It also introduces Proof of Participation, vs Proof of Work and Proof of Stake.

What is a Utility Token, Security Token and Equity Token?

A lot of crypto companies form with a purpose not to be a security token, due to the regulations and oversight. Hence, these companies establish themselves as a utility token, which bears a key to open the door to something. Security and Equity tokens provide many financial advantages, but the legal foundation is not firmly established – however the future for them is promising.

How Quantum Diamonds Will Help Us Detect Cosmic Collisions

Back in 2015, the two detectors that make up the experiment called LIGO detected gravitational waves generated by two merging black holes. And now, some researchers believe they can build instruments that can detect gravitational waves even LIGO can’t see — instruments that would be small enough to fit on a table top.

Though the device is yet to be built, researchers believe a device like this that’s as small as 1 meter long could reveal low frequency gravitational waves. The proposed device would use nanoscale diamonds with defects, called nitrogen-vacancy centers or NV centers.
