ETH2.0 Technical Research and Test Deployment

1. Comparison Between ETH1.0 and ETH2.0

1.1 Consensus Mechanisms

ETH1.0: Proof of Work (PoW)
ETH2.0: Proof of Stake (PoS)

Key Improvements in PoS:

Energy-efficient: Lower power consumption vs. PoW.
Lower barriers: Reduced hardware requirements.
Decentralization: Easier node participation.
Security: Higher attack costs due to slashing penalties.

1.2 Node Composition

ETH1.0	ETH2.0
Single execution client (e.g., Geth)	Execution client + Consensus client

Execution Clients:

Consensus Clients:

2. ETH2.0 Architecture

2.1 Node Structure

Layer	Responsibilities
Execution	- Manages transactions and state. - Generates execution payloads. - Provides RPC endpoints.
Consensus	- Validates blocks/attestations. - Tracks chain head and finalization. - Manages validator rewards/penalties.

2.2 Execution-Consensus Communication

Engine API: Facilitates cross-layer instructions.
Shared ENR: Combines ETH1 and ETH2 keys.
Gossip Protocol: Used for block/attestation propagation.

Block Production Flow:

Consensus layer notifies execution client.
Execution client creates a block from mempool.
Consensus layer packages transactions into beacon blocks.

3. Test Environment Setup

3.1 Client Selection

Based on client diversity stats, we used:

Execution: Geth v1.11.3
Consensus: Prysm

3.2 Hardware Requirements

OS: Ubuntu 20.04
CPU: 4+ cores @ 2.8GHz
RAM: 16GB+
Storage: 2TB SSD
Network: 8 Mbps

3.3 Deployment Steps

3.3.1 Install Prysm

cd /mnt/d/eth2.0/ethereum/consensus/prysm
curl https://raw.githubusercontent.com/prysmaticlabs/prysm/master/prysm.sh --output prysm.sh && chmod +x prysm.sh

3.3.2 Run Geth

nohup ./geth --goerli --http --http.api eth,net,engine,admin --authrpc.jwtsecret /path/to/jwt.hex 2>> geth.log &

3.3.3 Start Prysm Beacon Chain

nohup ./prysm.sh beacon-chain --execution-endpoint=http://localhost:8551 --prater --jwt-secret=./jwt.hex 2>> prysm.log &

👉 Optimize your node setup with advanced configurations.

4. Validator Deployment

4.1 Generate Keys

./deposit.sh new-mnemonic --num_validators 1 --chain goerli

4.2 Upload Deposit Data

Submit deposit_data-*.json to Goerli Launchpad.
Stake 32 Goerli ETH (testnet).

4.3 Monitor Activation

Use Beaconcha.in to track validator status.
Activation takes ~16-24 hours.

5. FAQs

Q1: How does PoS improve scalability?

ETH2.0’s PoS reduces energy use by 99.95% and enables sharding for horizontal scaling.

Q2: What if my validator goes offline?

You incur minor penalties (~-10,680 GWei/epoch). Repeated downtime risks slashing.

Q3: Can I run a node on Raspberry Pi?

Possible with lightweight clients (e.g., Nimbus), but full nodes require SSD and 16GB RAM.
