5 Key Foundations That Make Up Bitcoin

What are the key foundations that make up Bitcoin? Bitcoin is a new form of money. On the face of it, it’s a peer-to-peer digital money, that allows people to send value to one another.

But there is so much more to Bitcoin. It’s software program that’s decentralized and downloaded on thousands of devices around the world.

The Internet is a good analogy to use. It’s a globally interconnected network of computers, which use the Internet protocol suite (TCP/IP) to link devices worldwide.

The Bitcoin protocol is similar, but being the Internet of Value, Bitcoin is also very different from the Internet.

So what is Bitcoin? In this article we look at five key foundations of Bitcoin that make it truly revolutionary.


Bitcoin is a democracy. There is no centralized authority or anything that decides what happens to it or if any changes can be made to it.

Any developers wanting to implement protocol upgrades that will benefit the Bitcoin network have to get consensus from the community.

For a developer to introduce an upgrade, they first have to achieve ‘rough consensus’ from the developer pool. This means they don’t need 100% approval, but they need to get to the point where there are “no reasonable objections towards their proposal.”

Developers will discuss the proposal among everyone who might be affected by it, and pretty much anybody who is interested in the proposal can become part of the discussions.

This is usually done through mailing lists, code repositories, or social media.

Anything that is considered worthwhile will then be integrated, but even then, upgrades do not have to be utilized by every node if it doesn’t suit them.

So, a key feature of Bitcoin truly is a democracy, and any decision is taken from consensus which no centralized entity can change otherwise.

Bitcoin consensus mechanism is a key feature of its foundations


Another key foundation that makes up Bitcoin is its decentralization, which is made up through its network of computers running the protocol.

These are miners and nodes, and every one of them far and wide make up the decentralized nature of Bitcoin. This helps maintain the security of the protocol and makes it virtually impossible to control.

Some see entities such as mining pools as a danger to Bitcoin’s decentralization, and while they might centralize Bitcoin to a degree, they’re not a danger.

This is because no mining pool has sufficient capacity for controlling the consensus. Mining pools are also made up of tens of thousands of individual miners, who could easily move away from their pool if the mining pool was to try anything malicious.

A key feature of Bitcoin is its decentralization

By distributing power to as many different locations as possible, we nullify the possibility of a central entity seizing control. And as more people and companies flock towards Bitcoin and either mine or run a node, it will naturally become more decentralized.


With any payment mechanism we use (until Bitcoin), whether it’s a bank, VISA, or PayPal, we have to trust a third party. We have to believe that they will honour our transaction. And we have to pay for that trust.

Putting trust in legacy financial and political systems has got us to where we are today. We regulalrly see political and financial collapses everywhere, and these problems breed inequality and division.

Bitcoin eradicates the need for trust. Through the use of cryptography and a decentralized network, we have a system that needs no trust. This is because the trust is in the code, and without consensus the code cannot be altered, meaning that trust (and trustless) is absolute.

This trustless property of Bitcoin allows, for the first time, value to be sent from one person to another without the need of a third party. And with the code unable to send something astray, and the ledger being public people cannot deceive each other.

one of Bitcoin's key features is its trustless nature

Open Source

Another key foundation that makes up Bitcoin is its open source nature. It’s a fact that of all protocols, open source protocols are the most successful.

Bitcoin’s client is open for anybody to audit, and this ensures the trustless nature need not be questioned.

Because it’s open source anybody can copy it, as we have seen with the bearing of cryptocurrencies like Litecoin and Dogecoin, which are basically modified copy pastes of the Bitcoin protocol.

Its open source nature allows anybody to modify it, too, but as we know through the consensus function it will not be implemented without the consensus of the majority.

However, anybody trying to misbehave with the protocol will be penalized and cut off from the network. Therefore, it should be a warning to any developer wanting to try something: It’s not worth wasting your time.

Censorship Resistant

Another problem with centralized entities is that they can censor your everyday transactions. Whether it’s tweeting your opinion or sending money to someone, any centralized entity has control over you.

The government of Argentina has even censored how much peso its people can exchange for US dollars every month.

And the Venezulean banks have started to prevent clients using foreign IP addresses from using online banking.

It’s done because the governemnts don’t want the people taking value out of their failing economies, and with it a loss of control.

Nothing can stop a Bitcoin transaction. Well, miners can refuse to confirm one, but as long as somebody pays a competitive fee, it is highly unlikely that their transaction won’t be confirmed.

And because we don’t have to rely on a third party, nothing can stop somebody wanting to send a BTC transaction.

Bringing It All Together

There are many key features to Bitcoin, but having a network that relies on a democratic consensus is key to its very foundations.

And the network built on distributed computers ensures that the consensus will always be democratic. These together secure the protocol, and knowing the code is open source and auditable for anyone, means we don’t have to trust anyone with our transactions. And the best thing is transactions can’t be censored.

There are many foundations that make up Bitcoin, and the more you learn about it, the more amazing it appears that Satoshi thought of pretty much everything.

Bitcoin is the greatest innovation in generations, and if it is to be the success many expect, it could turn out to be the greatest innovation in history.

Bitcoin FAQs

Where can I buy Bitcoin in Italy?

There are several reputable Bitcoin exchanges operating in Italy. However, the most recommended exchanges are Kraken or BlockFi. Or you can buy Bitcoin from Bitcoin marketplaces, such as LocalBitcoins or Paxful. All of these exchanges and marketplaces are global with high liquidity and excellent customer service. Check out our reviews on each platform.

Can you buy less than 1 Bitcoin?

Yes. Every Bitcoin can broken down into 100 million bits. They are known as satoshis, after the pseudonymous creator Satoshi Nakamoto. And some companies will let you buy as little as $1 worth of Bitcoin, which at time of writing is worth about 11,000 satoshis. There are many companies that have a system for dollar cost averaging (DCA). This is a great way to buy Bitcoin, and is known in the space as ‘Stacking Sats’. Basically, what you do is set up small automatic, recurring payments to buy Bitcoin (or sats), and you DCA over time.

Can you get rich from Bitcoin?

You can get rich from Bitcoin, but most people haven’t. Anybody who expects to get rich, especially from a little investment, will likely be disappointed. Bitcoin isn’t a get rich quick scheme, and should be seen as a risky and volatile asset that could bring gains for anybody who can stomach volatility. If you’re interested in and want to buy Bitcoin, you should really have a long term plan.

Where can I earn free Bitcoin?

Nothing is really free, because even when you earn free Bitcoins you’re giving up your time, which is precious. But you can earn free Bitcoins. If you are a gamer, there are games like Bitcoin Bounty Hunt where you shoot your way to Bitcoin riches. Or there’s Carrot – a platform where you can earn free Bitcoin for doing tasks. Or you can save your Bitcoin in an interest bearing account and earn some Bitcoin interest. Be careful with interest bearing accounts, and only go with legitimate companies, though. I recommend Blockfi, you can read the review here.
