What is a blockchain?

What is a blockchain? tonsamith 10 Views • 2 years ago

What Is a Blockchain?
A blockchain is a distributed database that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. The innovation with a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party.

One key difference between a typical database and a blockchain is how the data is structured. A blockchain collects information together in groups, known as blocks, that hold sets of information. Blocks have certain storage capacities and, when filled, are closed and linked to the previously filled block, forming a chain of data known as the blockchain. All new information that follows that freshly added block is compiled into a newly formed block that will then also be added to the chain once filled.

A database usually structures its data into tables, whereas a blockchain, like its name implies, structures its data into chunks (blocks) that are strung together. This data structure inherently makes an irreversible timeline of data when implemented in a decentralized nature. When a block is filled, it is set in stone and becomes a part of this timeline. Each block in the chain is given an exact time stamp when it is added to the chain.

This is an original 16mm Scopitone conversion, not a copy. I used an actual old scopitone player, fed the signal to an old VHS, of which I then fed the output to a Canopus ADVC300. This 'summer of love' 1967 hit record was remuxed in 2006. Also fixed audio-sync.
Sound engineer of this famous mono mix was Keith Grant. Vocals and piano played by Gary Brooker. Matthew Fisher played the Hammond organ, and these original lyrics were written by Keith Reid;

We skipped the light fandango
turned cartwheels 'cross the floor
I was feeling kinda' seasick
the crowd called out for more
the room was humming harder
as the ceiling flew away
when we called out for another drink
the waiter brought a tray

and so it was that later
as a mirror told its tale
that her face at first just ghostly
turned a whiter shade of pale

She said: "There is no reason
and the truth is plain to see"
but I wandered through my playing cards
would not let her be
one of sixteen vestal virgins
who were leaving for the coast
and although my eyes were open
they might just as well've been closed

and so it was that later
as the miller told his tale
that her face at first just ghostly
turned a whiter shade of pale..

This composition stands tall on its own. Every song out there is *inspired* by those from other songwriters, you don't need to brag about your miracle discovery. So please stop commenting about it being 'originally written by' Johann Sebastian Bach?

Much gratitude goes to Gary, Matthew and the Keiths for having the heart to let me keep this ad-free, non-monetized, scopitone-conversion on YouTube! Still, without claiming any right to the original song I do have to put a Copyright Disclaimer up here;
Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research. Fair use is a use permitted by copyright statute that might otherwise be infringing. Non-profit, educational or personal use tips the balance in favor of fair use.
