Bitcoin Nottingham

Welcome to Bitcoin Nottingham! This is an open group for anyone with an interest in Bitcoin and cryptocurrencies.

We host friendly meetups for cryptocurrency enthusiasts in Nottingham and surrounding areas, as well as providing help and support for people new to using Bitcoin.

Meetups

We hold regular meetups, which are free for anyone to attend.

These meetups consist of educational talks explaining how Bitcoin works and how to use it. Bitcoin can seem like a complex technology at times, but with the right explanation it's simpler to get to grips with than you think.

This meetup group is suited to both beginners and those more experienced with using cryptocurrency. So no matter your current skill level, come along and ask some questions!

Services

We've been working with Bitcoin for over 5 years, and we've earned a deep understand of the technology over that time. We now use those skills to help others to learn how to get started with Bitcoin, as well as developing tools and websites for business.

Our services include:

If you have a question, idea, or if looking to get something built, get in touch and we'll see if we can help.

What is Bitcoin?

Bitcoin is called a digital currency. It allows you to make payments to anyone else in the world, without the need to open up a bank account. Bitcoin is borderless, and has no restrictions on who can use it, which makes it the first global currency.

This does mean that you are in charge of the safety and security of your Bitcoins, as there are no "middlemen" such as banks handling transactions. So if you make a mistake or lose access to your bitcoins, there is no bank you can call to recover your money or reverse a transaction. This doesn't have to be a problem, but it can seem scary at first.

This is why security is so important in Bitcoin, and is the reason why we run this group to help build an understanding of the technology. The better you understand the technology, the more comfortable you become with using it.

How does Bitcoin work?

Bitcoin is essentially a network of computers that all share a copy of the same file. This file is called the "blockchain", and it is a giant list of transactions.

When you make a bitcoin transaction, you basically "insert" it in to a computer that's running the Bitcoin computer program (it doesn't have to be your computer). The Bitcoin program will then relay that transaction to all the other computers it is connected to, and within a matter of seconds, every computer on the network will have a copy of your transaction.

From here, all of these computers will try and "mine" your transaction on to the blockchain. This process is a network-wide competion that uses a significant amount of processing power, and is necessary for sorting transactions and making sure that the blockchain remains secure. At roughly 10 minute intervals, one of the computers on the network will mine your transaction on to the blockchain, and your payment is complete and can never be reversed.

This system creates a decentralised payment processing network that has no restrictions and no central point of control. Anyone is free to create their own account (also known as an "address") and start sending and receving payments with people all over the world.

How do I get started?

The best way to get started is to download your own Bitcoin "wallet". Here are some of my recommendations:

These wallets allow you to easily send and receive bitcoins. They do this by managing your "private keys" and "addresses", which are like your passwords and account numbers.

TIP: Never give away your private keys or "seeds". These are your secret passwords and should be kept secret at all times.

From here, you can securely receive your first Bitcoins by giving someone one of the "addresses" found inside your wallet.
