🧬All About Nodes: How Crypto Hosting Providers Work
As of July 2023, there are 7,044 full nodes deployed on the Bitcoin blockchain, and 1,440 full nodes and 410,529 validator nodes on Ethereum . They store copies of blockchains and verify transactions against consensus rules.
To perform these operations, computers with a large hard drive and a constant Internet connection are needed, which is why cryptocurrency investors often delegate node maintenance to hosting providers.
One such company is Allnodes . In a joint special project, we will talk about the types of nodes and the features of the operation of cryptocurrency hosting providers. The practical part of the special project includes instructions on staking on Allnodes and launching a validator node on the Ethereum 2.0 network.
What is a Node 👈
Node is any computer connected to the blockchain. Nodes exchange information about blocks and transactions with each other.
The main purpose of nodes is to provide reliable storage and transmission of data on the network. For this they:
- store a copy of the blockchain — the history of transactions and blocks;
- use computing power to confirm blocks and transactions;
- update other nodes in the blockchain.
The transfer of information between nodes is regulated by consensus protocols, such as Proof-of-Work (PoW), Proof-of-Stake (PoS), Proof-of-Authority (PoA), Delegated Proof-of-Stake (DPoS) and others.
Users run full nodes to:
- check the state of the blockchain and reject blocks and transactions that do not comply with the consensus rules;
- securely interact with the network without trusting other nodes;
- send and receive transactions anonymously without transferring metadata and addresses to third-party services.
As the number of nodes grows, the blockchain becomes more decentralized and the network becomes more resilient to system failures or power outages.
Node types 👈
Blockchains support several types of nodes: full nodes, light nodes, masternodes, and nodes that can mine blocks.
Light Nodes
When interacting with the blockchain, they rely on full nodes. They do not store a copy of the blockchain and only request the last blocks before sending a transaction.
Running a light node does not require many resources — users sacrifice security for convenience.
Full nodes
They act as a server — they store a copy of the blockchain, verify transactions and blocks, and maintain consensus on the network.
They are divided into two types:
- Stripped down nodes . At the first start, the blockchain is loaded and verified. In the future, old blocks are deleted when the limit set by the user is reached, for example, 20 GB.
- Archive nodes . They store the entire blockchain. Includes mining, staking and masternodes.
⛏Mining nodes
Miners are full nodes on blockchains with the Proof-of-Work consensus algorithm. To add a block, they perform complex calculations and provide proof of the work done.
Miners send this data to the network for verification by other full nodes. Once consensus is reached, one or more miners are given the right to add a block to the chain.
For their work, miners receive transaction fees and a reward — a predetermined number of coins.
🙇♂️Staking nodes
Stakers (validators) are full nodes in blockchains with the Proof-of-Stake consensus algorithm.
To add blocks and receive rewards, you need to deploy a full node and block part of the coins in it — send them to staking. This can be compared to a traditional deposit: participants receive income for storing cryptocurrency in their account.
Staking does not require powerful equipment: the probability of obtaining a block depends on the number of locked coins.
🛠Masternodes
They do not add blocks to the chain, but only verify and confirm transactions. For this, they receive a part of the rewards for the mined blocks.
Hosting Providers👈
-What are they doing
Cryptocurrency hosting provider is a platform that provides users with services for the deployment and smooth operation of nodes in various blockchains.
Typically, self-deploying a node requires:
- upload a large amount of data. According to the analytical service Statista , in July 2022, the bitcoin blockchain weighed 406 GB ;
- have a computer with a large hard drive and a permanent Internet connection. Hardware must meet minimum system requirements;
- get acquainted with the features of the work of nodes in the blockchain.
In addition, in PoS networks, validators can lose some of the cryptocurrencies in staking if consensus rules are violated or equipment is idle.
Hosting providers solve these problems by setting up nodes for delegating cryptocurrencies and providing users with servers with high uptime.
For their services they charge:
- when deploying nodes — a commission from the income of customers or a fixed fee for hosting;
- when delegating cryptocurrencies, it is part of the staking reward.
According to the portal Staking Rewards , in July 2022, 220 such projects were operating on the market, including one of the largest hosting providers, Allnodes.
