You should understand the concept of a decentralized network before diving deeper and running your own instance of an Ethereum client. Take a look at our introduction to Ethereum.
What are nodes and clients?
Many implementations of Ethereum clientshg0088线上 exist in a variety of languages. What these client implementations have in common is they all follow a formal specification. This specification dictates how the Ethereum network and blockchain functions.
- Stores full blockchain data.
- Participates in block validation, verifies all blocks and states.
- All states can be derived from a full node.
- Serves the network and provides data on request.
- Stores the header chain and requests everything else.
- Can verify the validity of the data against the state roots in the block headers.
- Useful for low capacity devices, such as embedded devices or mobile phones, which can't afford to store gigabytes of blockchain data.
- Stores everything kept in the full node and builds an archive of historical states. Needed if you want to query something like an account balance at block #4,000,000.
- These data represent units of terabytes which makes archive nodes less attractive for average users but can be handy for services like block explorers, wallet vendors, and chain analytics.
- Your node verifies all the transactions and blocks against consensus rules by itself. This means you don’t have to rely on any other nodes in the network or fully trust them.
- You won't have to leak your addresses and balances to random nodes. Everything can be checked with your own client.
- Your dapp can be more secure and private if you use your own node. , and some other wallets can be easily pointed to your own local node.
- They provide access to blockchain data for lightweight clients that depend on it. In high peaks of usage, there need to be enough full nodes to help light nodes sync. Light nodes don't store the whole blockchain, instead they verify data via the state roots in block headers. They can request more information from blocks if they need it.
- Full nodes enforce the proof-of-work consensus rules so they can’t be tricked into accepting blocks that don't follow them. This provides extra security in the network because if all the nodes were light nodes, which don't do full verification, miners could attack the network and, for example, create blocks with higher rewards.

- easy customisation.
- light integration into services or products.
- minimal memory and storage footprint.
- an optimized virtual machine
- state access
- networking and rich features like Prometheus/Graphana dashboards, seq enterprise logging support, JSON RPC tracing, and analytics plugins.
- Full – downloads all blocks (including headers, transactions and receipts) and generates the state of the blockchain incrementally by executing every block.
- Fast (Default) – downloads all blocks (including headers, transactions and receipts), verifies all headers, and downloads the state and verifies it against the headers.
- Light – downloads all block headers, block data, and verifies some randomly.
- Warp sync – Every 5,000 blocks, nodes will take a consensus-critical snapshot of that block’s state. Any node can fetch these snapshots over the network, enabling a fast sync.
- Beam sync – A sync mode that allows you to get going faster. It doesn't require long waits to sync, instead it back-fills data over time.
- Header sync – you can use a trusted checkpoint to start syncing from a more recent header and then leave it up to a background process to fill the gaps eventually
Setting up light sync in GETH
geth --syncmode "light"
Setting up header sync in Trinity

The most convenient and cheap way of running Ethereum node is to use a single board computer with ARM architecture like Raspberry Pi. provides images of Geth, Parity, Nethermind, and Besu clients. Here's a simple tutorial on how to build and setup an ARM client.
