What is a blockchain?

What is a blockchain? tonsamith 31 Views • 4 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.

The meditations were begun with one purpose: simply to try and help people. Every meditation is produced with genuine care and love for those people who use them, because we too, have needed the kind of help our meditations are trying to offer others.

Our ethos is to be as all-inclusive and as neutral as possible. We have no religious or other affiliations and try to keep most of our meditations suitable for everyone. We always welcome comments, feedback & suggestions and actively engage with our subscribers via our Facebook page.
