# Nodes and Clients Are a Mirror of How Humans Coordinate

## Abstract

The terms "node" and "client" are used interchangeably in the Ethereum community, creating massive confusion for newcomers and even experienced developers.

A "node" is not software, it's a running instance of the network. "Clients" are the actual software programs (Geth, Nethermind, Lighthouse, Prysm) that connect your computer to the network.

This article clears up the confusion by explaining what nodes and clients actually are, how execution clients differ from consensus clients, why you need both post-Merge, which combinations work best (Geth+Lighthouse, Reth+Prysm, etc.), and how real projects like Infura, Alchemy, Coinbase, and solo stakers run infrastructure. Through simple analogies and real examples, you'll finally understand the architecture everyone assumes you already know.

:::info
**What you'll learn:**
- Node vs Client (they're NOT the same!)
- Execution vs Consensus clients
- Why you need BOTH after The Merge
- Popular client combinations
- How Infura, Alchemy run infrastructure
- Hardware requirements for running nodes
- Which clients projects actually use

## Introduction: The Terminology Trainwreck

I was on a Discord call with some Ethereum developers.

Someone said: "I'm running a node."

Me: "Cool! Which client?"

Them: "What do you mean? I said I'm running a node."

Me: "Yeah, but which client software?"

Them: "The node IS the software."

Me: "No, the client is the software. The node is—"

Them: "Node, client, same thing."

**Me: "...are they though?"**

This conversation happens ALL THE TIME. 😅

Even experienced devs mix these up. Documentation uses them interchangeably. Tutorials confuse everyone.

So let me clear this up once and for all:

:::info
**Key takeaway:**
- A **Node** is *not* software
- A **Client** *is* software
- You run a **Node** by using a **Client**
:::

Still confused? Don't worry. By the end of this article, you'll understand:
- What a node actually is
- What a client actually is
- Why we have TWO types of clients now
- Which software combinations work
- How real companies run infrastructure

Let's fix this confusion!

## What Is a Node? (Not What You Think)

In simple terms, A node is **a computer participating in the Ethereum network**.

:::info
**The key insight:**
- **Node** → a running instance of the network
- **Client** → software that connects to and runs that instance

Think of it like:
- Email **server** (node) vs Outlook **software** (client)
- Web **server** (node) vs Browser **software** (client)
- Bitcoin **full node** (node) vs Bitcoin Core **software** (client)

The **node** is the thing running.
The **client** is the software that makes it run.
:::

:::info
**The Coffee Shop Analogy:**

Think of the Ethereum network as a **city full of coffee shops**.

- **Each coffee shop = one NODE**
- A physical place
- Serves customers (processes transactions)
- Talks to other shops (gossip protocol)
- Part of the same city (network)

- **The employees = CLIENT software**
- Geth employees (Go)
- Reth employees (Rust)
- Nethermind employees (C#)
- Different implementations, same job

Your laptop running **Geth** = your coffee shop staffed by Geth employees
My server running **Reth** = my coffee shop staffed by Reth employees

All coffee shops working together = **the Ethereum network**
:::

**What a node does:**

An Ethereum node is a running participant in the network that stores the blockchain, validates transactions, executes smart contracts, gossips with other nodes, participates in consensus, and serves data to users.

Your laptop becomes a node the moment you install client software like Geth or Reth, start it running, connect it to other nodes, and allow it to sync the blockchain. At that point, the machine itself is the node — Geth or Reth is simply the client software making it all work.

---

## What Is a Client? (The Actual Software)

In simple terms, A client is **software that implements the Ethereum protocol**.

**Think of it like web browsers:**

:::info
The Ethereum network is like the web.
Clients are like browsers.

- **Chrome → Geth**
- Written in: Go
- Built by: Ethereum Foundation
- Job: Execute and verify Ethereum blocks

- **Firefox → Nethermind**
- Written in: C#
- Built by: Nethermind
- Job: Execute and verify Ethereum blocks

- **Safari → Besu**
- Written in: Java
- Built by: Hyperledger
- Job: Execute and verify Ethereum blocks

Different software.
Same protocol.
Same network.
:::

**Ethereum clients:**

Execution Clients (for transactions):
  Geth:
    Language: Go
    Team: Ethereum Foundation
    Market share: ~40%
    
  Reth:
    Language: Rust
    Team: Paradigm
    Market share: ~15%
    
  Nethermind:
    Language: C#
    Team: Nethermind
    Market share: ~20%
    
  Besu:
    Language: Java
    Team: Hyperledger
    Market share: ~10%
    
  Erigon:
    Language: Go
    Team: Erigon Team
    Market share: ~10%

Consensus Clients (for proof-of-stake):
  Lighthouse:
    Language: Rust
    Team: Sigma Prime
    Market share: ~35%
    
  Prysm:
    Language: Go
    Team: Prysmatic Labs
    Market share: ~30%
    
  Teku:
    Language: Java
    Team: ConsenSys
    Market share: ~15%
    
  Nimbus:
    Language: Nim
    Team: Status
    Market share: ~10%
    
  Lodestar:
    Language: TypeScript
    Team: ChainSafe
    Market share: ~5%

**Why multiple clients?**

Client diversity prevents catastrophic failure:

Scenario: Bug in Geth
  If 100% use Geth: Network HALTS 
  If 40% use Geth: Those nodes stop, others continue 
  
Real example - 2021 Geth bug:
  - Bug caused Geth nodes to crash
  - But only 70% were Geth
  - 30% (Nethermind, Besu, etc.) kept network alive
  - Network continued! Crisis averted!

Client diversity = Network resilience

---

## The Two-Client Architecture (Post-Merge)

After The Merge (September 2022), Ethereum split into TWO layers:

**Before The Merge:**

In the early days of Ethereum, a single client did everything. Geth handled transactions, executed smart contracts, mined blocks under Proof of Work, and validated the chain all within one program. This made the system simple to understand and easy to run, but it was also inflexible, tightly coupled, and harder to evolve as the network grew.

**After The Merge:**

Now you need TWO clients:

[Execution Client]       [Consensus Client]
(Geth, Reth, etc.)      (Lighthouse, Prysm, etc.)
        ↕                         ↕
  Handles transactions      Handles validators
  Executes contracts        Manages consensus
  Updates state             Proposes blocks
                    ↕
              Engine API
              (They talk!)

**The Restaurant Analogy: Why Execution & Consensus Clients Exist**

:::info
**Before (One Person):**
The chef does EVERYTHING:
- Takes orders
- Cooks food
- Manages the restaurant
- Cleans
- 😰 Too much work!

**After (Two People):**
- **Chef → Execution Client**
- Only cooks food
- Executes orders
- Super focused!

- **Manager → Consensus Client**
- Takes orders
- Coordinates everything
- Manages schedule
- Super focused!

**How they interact:**
- Manager → Chef: "Cook this order!"
- Chef → Manager: "Done! Here's the food!"

**Key takeaway:** Specialization = better performance!

## Execution Clients: What They Do

**Role:**
Handle all transaction execution and smart contracts.

**Responsibilities:**

1. Transaction Pool (Mempool):
   - Receive transactions from users
   - Validate signatures
   - Check gas fees
   - Store in mempool

2. Execute Transactions:
   - Run EVM bytecode
   - Update account balances
   - Execute smart contracts
   - Calculate state changes

3. State Management:
   - Store the state trie
   - Track all accounts
   - Manage storage
   - Handle historical data

4. Serve Data:
   - RPC endpoints (JSON-RPC)
   - eth_call, eth_getBalance, etc.
   - Return blockchain data
   - Support dApps and tools

**When you interact with Ethereum:**

// Your dApp calls:
const balance = await provider.getBalance(address);

// This goes to:
Execution Client (Geth, Reth, etc.)
    ↓
Looks up in state trie
    ↓
Returns balance

The execution client handles ALL user queries!

---

## Consensus Clients: What They Do

**Role:**
Handle proof-of-stake consensus and validators.

**Responsibilities:**
1. Validator Management:
- Track all validators
- Monitor validator balances
- Handle deposits/withdrawals
- Manage validator keys

2. Block Proposals:
- Decide who proposes next block
- Select block from builders
- Sign and broadcast
- Coordinate with execution client

3. Attestations:
- Validators vote on blocks
- Collect attestations
- Verify 2/3+ consensus
- Achieve finality

4. Beacon Chain:
- Maintain consensus layer
- Track epochs and slots
- Manage finality
- Coordinate network

**The Block Proposal Flow:**

Every 12 seconds:

Consensus Client:
1. "It's my turn to propose!"
2. Asks Execution Client: "Build me a block"
3. Execution Client: Builds block with transactions
4. Consensus Client: Gets block, signs it
5. Broadcasts to network

Other Consensus Clients:
1. Receive block proposal
2. Send to their Execution Client: "Validate this"
3. Execution Client: Validates transactions
4. Consensus Client: Attests if valid

If 2/3+ attest → Block accepted!

## Setting Up Your Own Node

**Basic setup (Geth + Lighthouse):**

# 1. Install Geth
wget https://gethstore.blob.core.windows.net/builds/geth-linux-amd64.tar.gz
tar xvf geth-linux-amd64.tar.gz
sudo cp geth /usr/local/bin/

# 2. Install Lighthouse
wget https://github.com/sigp/lighthouse/releases/download/latest/lighthouse-linux.tar.gz
tar xvf lighthouse-linux.tar.gz
sudo cp lighthouse /usr/local/bin/

# 3. Generate JWT secret (they use this to talk)
openssl rand -hex 32 > /tmp/jwtsecret

# 4. Start Geth (Execution Client)
geth \
  --http \
  --http.api eth,net,web3 \
  --authrpc.addr localhost \
  --authrpc.port 8551 \
  --authrpc.jwtsecret /tmp/jwtsecret

# 5. Start Lighthouse (Consensus Client)
lighthouse bn \
  --network mainnet \
  --execution-endpoint http://localhost:8551 \
  --execution-jwt /tmp/jwtsecret \
  --checkpoint-sync-url https://beaconstate.info

# They're now talking via Engine API!
# Your node is running! 

**What happens:**

Step 1: Geth starts syncing
  - Downloads blockchain state
  - Builds state trie
  - Takes 12-24 hours

Step 2: Lighthouse starts syncing
  - Downloads beacon chain
  - Syncs validator data
  - Takes 1-2 hours (with checkpoint sync)

Step 3: They connect via Engine API
  - Geth exposes port 8551
  - Lighthouse connects to it
  - JWT secret authenticates
  - They start working together

Step 4: Your node is live!
  - Geth handles transactions
  - Lighthouse handles consensus
  - You're part of the network!

---

## Monitoring Your Node

**What to watch:**

Execution Client:
  - Sync status (is it syncing?)
  - Peer count (are you connected?)
  - Block height (are you up to date?)
  - Memory usage (below 32GB?)
  - Disk usage (enough space?)

Consensus Client:
  - Beacon sync (is it synced?)
  - Attestation rate (if validator)
  - Participation rate
  - Finality status
  - Peer count

Network:
  - Bandwidth usage (~10GB/day)
  - Connection stability
  - Firewall ports open

**Tools to use:**

# Geth monitoring
geth attach http://localhost:8545
> eth.syncing
> net.peerCount
> eth.blockNumber

# Lighthouse monitoring
lighthouse bn --http --http-address 127.0.0.1
curl http://localhost:5052/eth/v1/node/health

# System monitoring
htop  # CPU and RAM
df -h # Disk space
iftop # Network usage

---

## Client Diversity: Why It Matters

**The 2016 Shanghai Attack:**

What happened:
  1. Geth had a bug in gas calculation
  2. Attacker sent specially crafted transactions
  3. Geth nodes crashed
  4. Network slowed dramatically
  
Why it wasn't catastrophic:
  - Parity (old EL client) didn't have the bug
  - ~30% of nodes stayed online
  - Network continued (slowly)
  - Geth fixed bug and recovered

If 100% were Geth:
  - Entire network would have halted
  - No transactions possible
  - Total disaster

Client diversity saved Ethereum!

**The Merge Client Diversity:**

Current distribution (2025):

Execution Layer:
  Geth: 40% ⚠️ (Too high!)
  Nethermind: 20%
  Reth: 15%
  Besu: 10%
  Erigon: 10%
  Others: 5%

Consensus Layer:
  Lighthouse: 35%
  Prysm: 30%
  Teku: 15%
  Nimbus: 10%
  Lodestar: 5%
  Others: 5%

Goal: No client >33%
Why: Need 2/3+ for consensus
If one client >33% has bug → can't finalize!

**How to help client diversity:**

If you're running:
  Geth + Lighthouse → Consider switching Geth!
  Try: Reth + Lighthouse
  Or: Nethermind + Lighthouse
  
Popular minority clients:
  - Reth (fast and modern!)
  - Besu (light on resources)
  - Nimbus (runs on low-end hardware)
  
Every node running minority clients helps!

## Common Misconceptions

### Misconception 1: "I'm running a Geth"

**Wrong:** Geth is not a thing you run. Geth is software.

**Correct:** "I'm running a node using Geth client"

You don't say "I'm running a Chrome"
You say "I'm using Chrome browser"

Same with Ethereum:
Not: "I'm running a Geth"
Yes: "I'm running a node with Geth"

---

### Misconception 2: "Node and client are the same"

**Wrong:** They're different concepts.

Node: The running instance
  - Your computer
  - Participating in network
  - Has IP address
  - Connects to peers

Client: The software
  - Geth, Reth, Lighthouse, etc.
  - Code you download
  - Runs on your node
  - Implements the protocol

Your node runs client software!

---

### Misconception 3: "I only need one client"

**Wrong:** After The Merge, you need TWO!

Before September 2022:
  - One client was enough (Geth, Parity, etc.)

After September 2022:
  - One client not enough
  - Need execution client (Geth, Reth, etc.)
  - Need consensus client (Lighthouse, Prysm, etc.)
  
Both must run together via Engine API!

---

### Misconception 4: "Running a node = mining/validating"

**Wrong:** Running a node is different from validating.

Running a full node:
  - Stores blockchain
  - Validates others' blocks
  - Doesn't propose blocks
  - No rewards
  - Anyone can do it!

Running a validator:
  - Requires 32 ETH staked
  - Proposes blocks
  - Gets rewards (~4% APR)
  - Requires validator keys
  - More responsibility

You can run a node without validating!
Many do it just to support the network.

---

## Key Takeaways

Let me summarize nodes vs clients:

### The Definitions

NODE:
  What: Running instance of the network
  Who: Your computer/server
  Does: Participates in Ethereum
  Is: The thing running
  
CLIENT:
  What: Software implementing protocol
  Who: Geth, Reth, Lighthouse, etc.
  Does: Makes your computer a node
  Is: The program you download

### The Architecture

Post-Merge (2022+):
Need TWO clients:

1. Execution Client:
- Geth, Reth, Nethermind, Besu, Erigon
- Handles transactions
- Executes smart contracts
- Manages state

2. Consensus Client:
- Lighthouse, Prysm, Teku, Nimbus, Lodestar
- Handles validators
- Proposes blocks
- Achieves consensus

They communicate via Engine API!

### Popular Combinations

Most popular:
  1. Geth + Lighthouse (40%)
  2. Nethermind + Lighthouse (15%)
  3. Reth + Prysm (10%)
  
Best for beginners:
  → Geth + Lighthouse
  (Most documentation)
  
Best for performance:
  → Reth + Prysm
  (Fastest sync)
  
Best for low-end hardware:
  → Besu + Nimbus
  (Runs on Raspberry Pi)

### Client Diversity

Goal: No client >33% market share

Why: Bug in majority client = chain halt

How to help:
  - Run minority clients
  - Switch from Geth if possible
  - Try Reth, Nethermind, or Besu
  
Every diverse node helps the network!

## Conclusion

Remember that Discord conversation from the beginning?

Now you know:
- A **node** is the running instance
- A **client** is the software
- You need **two clients** post-Merge
- Different clients do different jobs

**The correct way to talk about it:**

Before:
"I'm running a Geth node"

Better:
"I'm running a node using Geth and Lighthouse"

Even better:
"I'm running an Ethereum node with Geth as my execution client and Lighthouse as my consensus client"

Most accurate:
"My server is operating as an Ethereum node by running the Geth execution client and Lighthouse consensus client, which communicate via the Engine API to participate in the network"

(But honestly, the second one is fine)

**Why this matters:**

When everyone uses terms correctly:
- Documentation makes sense
- Tutorials are clearer
- Fewer confused developers
- Better communication
- Stronger ecosystem

**The node is not the software.**

**The client is the software.**

**You use clients to run a node.**

Say it with me!

Now go forth and correct people when they say "I'm running a Geth" 😄

But do it nicely, we've all been confused by these terms!
