Nodes in a blockchain keep the whole system functioning and secure. While cryptocurrencies and other blockchain-based applications get much of the attention, it is the blockchain nodes working diligently behind the scenes that truly power these networks.
A blockchain node is a computer or server that validates transactions on the network, keeping an updated copy for simultaneous broadcasting. It verifies digital signatures before adding them to the shared ledger.
In this article, we will explore what blockchain nodes are, why they are needed, how they function, and the different types of blockchain nodes that exist. By the end, you will have a solid foundation for understanding these essential components that make blockchains tick.
To understand their core functions, let's look under the hood of how blockchain nodes work:
While all serve to validate the blockchain, there are some different types of blockchain nodes based on their roles and capabilities:
There are various categories of nodes in blockchain filling different functions, with full nodes maintaining the most robust functionality to support the security of their respective networks long-term.
Blockchains rely on decentralization rather than a single point of control. Nodes dispersed across different regions and jurisdictions help achieve true decentralization by validating transactions independently. The loss of a few blockchain nodes would not compromise the whole network.
Having many nodes verifying transactions and blocks helps ensure no malicious actors can disrupt the network or alter records. At least 51% of nodes would need to collude to conduct a 51% attack, which becomes increasingly difficult on a larger scale.
With nodes globally distributed, it becomes nearly impossible for any government to censor transactions or shut down the entire blockchain. Even if some jurisdictions banned nodes, the network could still function.
Nodes in a blockchain provide access points for users, developers, and businesses to interact with applications built on a blockchain, helping to support widespread adoption and use cases. Without nodes, blockchains would have no way to connect to the outside world.
More nodes equals more processing power supporting the network. This increased performance capacity allows blockchains to handle higher transaction volumes and workloads as usage grows over time.
The exact number of nodes in the blockchain ecosystem varies by blockchain, but here are some statistics on the major networks based on available data:
As is visible, while the number of nodes varies, all major public blockchains have thousands to tens of thousands of nodes operating simultaneously.
This scale of decentralization helps ensure their security and censorship resistance. The higher the number of nodes, generally, the more robust the network.
There is no definitive number, as different studies have found blockchain security is maintained with different-sized networks of nodes. In general:
Absolutely. While not everyone will run their own node due to resource requirements, it is possible for users, businesses, or developers to set up nodes depending on the specific blockchain.
For most large blockchain networks like Bitcoin and Ethereum, individuals can download the necessary software and run a full archival node with no major barriers to entry. Others with more intensive needs may require additional technical knowledge or dedicated hardware.
Crypto staking and crypto mining operations typically require more dedicated server-grade equipment and long-term uptime to actively participate in consensus.
In all scenarios, though, users can opt to run remote or light nodes with reduced capabilities depending on their goals and constraints.
So while not mandatory, with the right technical skills and setup, anyone can become a node operator to directly support their desired blockchain in a decentralized fashion if they wish. Many even offer it as a commercial service.
For those interested in running nodes but lacking the hardware or expertise, several companies now offer blockchain infrastructure solutions through what's known as Node as a Service (NaaS).
Buying a blockchain node today is as easy as choosing a reputable NaaS provider. This lowers barriers to entry for newcomers or those wishing to use nodes without self-managing infrastructure.
Blockchain nodes form the backbone infrastructure powering these novel technologies in a decentralized manner.
Whether individuals choose to self-operate validators, delegate through exchanges, or use NaaS, node ownership will continue to grow the decentralized economies of blockchain networks worldwide.
A euro stablecoin like EURK, which is securely issued and audited, offers transparent transactions that are fast and secure for these digital economies. Blockchain combined with stablecoins like EURK pave the way forward for more accessible and inclusive digital economies globally.
