Owning crypto is all about control. That's why you're wise to consider running your own crypto node. That way you don't need to verify data through third parties. The chain is always checked by you and only you. That's the idea behind nodes. Running your nodes is one thing. Hosting is another place where you host matters too. If you're looking to do this in Europe, thinking about jurisdiction and compliance is also wise. Not to say that latency isn't important either. Here's a few things to think about in terms of cost, performance and legal risk when it comes to hosting a crypto node in Europe.
Latency & The Importance of Distance
The time that data requires to travel in between nodes is called latency. The lower the latency the faster the communication between the nodes. In the world of crypto networks, latency is in charge of the speed at which nodes receive new blocks, how fast it shares transactions, and your opportunities in mining or validator setups. In these terms, the Old Continent has quite a powerful infrastructure. Yet, not one universally shared.
What you need to know as far as latency goes in Europe, is the difference between central and edge locations. As you could probably have guessed, big data centres such as the ones in Paris, Amsterdam or Frankfurt, have superb connectivity. It's because of their location on main exchange points of the world wide web. Crypto node hosting at these locations is almost a guarantee of more stable routing, faster peer connections, and lower delays during peak traffic. The remote your hosting gets, the higher the latency is. The traffic will still move across borders, but with delays, which can sometimes be quite painful for the end user, you.
Also, if your work revolves around a validator code, latency is in charge of your rewards. Most networks favour faster nodes. Some penalize delays. Location is about both the cost and eventual income. That's why it is vital to locate your setup at major EU data centres which are located in Germany, France, and Netherlands. Also, cloud providers with EU regions covered could do the trick.
The Vital Point of Jurisdiction
Nodes are not lawless entities. Instead, they fall under a certain jurisdiction which is normally tied to the place where your node originates from. When it comes to EU nodes, matters can be complicated for you, if you're not in the subject. What causes the biggest issue is that each country has its own set of rules, but there's also an EU wide set of regulations.
Jurisdiction matters because you then know whether running a node is regulated, which set of data rules applies, and whether there's your liability if anything goes south. In some countries in order to run a node you need to register first. Other countries have no such requirement. The frameworks that cover the entirety of the European Union are known as Markets in Crypto Assets or MiCA. Its main goal is to create one set of regulations for the entire Union. The reason why you should not fear MiCA is because its main focus is on the service providers, and not all node operators fall under its jurisdiction. Yet, if your node serves as a support to a business of a kind, you might check thoroughly whether you're covered by MiCA.
While Europe tends to align its rules and regulations they will differ country to country. If you're hosting a node as a hobby, it is one matter, but if it's tied to a business, it is another matter. Another thing that matters is not only the location of the node server, but the location of you as an owner. That's why when you try to establish a hosting, think about where the server is, where's the operator, and who is in control of the node. When you know this, you know who legally you're actually covered.
How to Follow Compliance?
If you want to comply, you'll follow rules and laws. When it comes to the EU they love to put the accent on financial regulations and data protection. To have both in order, the European Union has put the General Data Protection Regulation (GDPR) in place. These regulations apply all over the EU. Considering that blockchains are used to store data, and that data can be personal at times, it can create an issue with GDPR. The main issue is the way a blockchain saves the data, and it is an unchangeable and undeletable way of storing data. According to GDPR, all people reserve the right to delete their personal data from data storages. In a way, your crypto node and GDPR can easily end up in a conflict.
If you're only going to process public data, you will most likely encounter no issues. Yet, if your node collects personal data, there might be problems. GDPR will affect your business if you log IP addresses, run APIS for others, and store user metadata. The basic things you need to do to avoid any potential issues is to avoid storing unnecessary personal data, use encryption on every step, and be transparent about what type of data you work with.
Furthermore, if your node is a part of a bigger business or a service, the basic requirements in Europe also become things such as KYC (Know Your Customer), and AML (Anti Money Laundering) checks. Also, and we hope you didn't think the points above were everything, the EU is very environment centred. Many countries have rules and regulations in terms of power consumption, and carbon footprint. These regulations matter more for mining than they do for nodes, but it is important to be aware of them nonetheless.
Summary
With everything above said, hosting a crypto node in Europe comes with some limitations, but none detrimental to your business. With that in mind, your main focus needs to be on latency, and to know whether your data centre is well connected, and is it close to other nodes. Secondly, pay attention to jurisdiction. The jurisdiction is best determined if you check in which country your server is, and what particular local and EU laws apply in that state. Lastly, you want to be in line with compliance. Sorting personal data is a no, while hosting nodes as a part of business should be carried out with risks in mind. If you can go around these issues with a clear conscience, you're good to go. Having in mind that the EU offers great infrastructure for hosting a crypto node, you at least should cover the basics of latency, jurisdiction and compliance.
