The Distributed Nature of Git and Bitcoin

For average software projects, you might push changes to a company's internal Git server, a random guy on the internet who runs one out of his house for free , or something like GitHub. These are effectively central servers in the eyes of the people , but not the underlying system. Yes, everything may pass through the central server, and yes, if that goes down, the people might have a small issue, but the system itself will still function. You can still work in Git without an active internet connection, you just can't share your work.

Many decentralized systems have at least one "central" server that isn't an authoritative source, but more of a well-known landmark that new joins can use to catch up on everything that they don't have yet. Okay, I've given examples, so now let's give some details. For those unaware, a Git repository is a database of many, many objects. For everyone with a copy - a git clone - they have the entire database.

Work sharing is done by updating someone else's database with the changes that you've made, and nothing more. Everyone's complete copy means everything can be done offline, and also means that if you lose your copy, someone nearby can just give you their's, and you're back up and running again. With normal fiat currencies, the bank decides everyone's balances. If I open the bank's app on my phone, I am told how much money I have available to spend at any given moment, not through validation or peer confirmation but because the bank, after looking through their records, has said that's how much I have.

And, side note, before you point out there being multiple banks, every real physical currency has at least one "bank" that's the central authority on that currency. It has to end somewhere. With Bitcoin, this is not true. A user has Bitcoin because the public ledger of transactions says that, after all the profits and losses, the end result of all that addition and subtraction canceling out is If I want to change this, I have to add the change to the network, and it needs to be accepted by the majority of the network.

The folks that verify and validate Bitcoin transactions are known as Bitcoin miners. They are an open and expanding group that anyone is free to join. People may join or leave as they wish, and in theory anyone in the network may participate in verifying the state of the network. Making sure that everyone sees the same balance for each user is a big deal. For currencies, if two clients disagree, that's an issue. But because everything is public, in theory, the worst that will happen is you have a slightly out-of-date number that will fix itself shortly.

Without, a central authority, you don't need to trust any single entity to ensure valid balances. This is all done in a decentralized fashion by the network of peers. In this sense, "right" and full consensus are just "what the majority agrees with. In sum, both Git and Bitcoin leverage distributed architectures with no required central authority. Git's distributed nature is a means to allow efficient team collaboration on digital projects.

Bitcoin uses decentralization to remove the need to trust a single party when it comes to currency transactions and decisions.

The Distributed Nature of Git and Bitcoin. These rules prevent previous blocks from being modified because doing so would invalidate all the subsequent blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively to the block chain. In this way, no group or individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.

This is a question often surrounded by confusion, so here's a quick explanation! The basics for a new user As a new user, you can get started with Bitcoin without understanding the technical details. Balances - block chain The block chain is a shared public ledger on which the entire Bitcoin network relies.

Transactions - private keys A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain.

Processing - mining Mining is a distributed consensus system that is used to confirm pending transactions by including them in the block chain. Going down the rabbit hole This is just a short summary of Bitcoin. Support Bitcoin.

    I apologise, but, in my opinion, you are mistaken. I can defend the position. Write to me in PM, we will communicate.
