What is Ethereum Beacon Chain?
The Ethereum Beacon Chain powers the next-generation ETH network and enables secure staking for millions of users. But how does it work—and what makes it essential to Ethereum’s future? Understanding the beacon chain is the key to unlocking the potential of Ethereum staking and building trust in the evolving ecosystem. In this guide, you'll learn what the beacon chain is, how it supports Ethereum 2.0, the fundamentals of staking (including with BETH), how consensus and validator rewards work, plus real-world use cases and security best practices. Whether you're a newcomer or ready to dive deeper, this article covers everything you need to know—including recent stats, leading explorers, and how to participate safely with OKX.
What Is the Ethereum Beacon Chain?
The beacon chain is the foundational backbone of Ethereum 2.0, designed to usher in proof-of-stake (PoS) consensus and transform the way Ethereum operates. Unlike Ethereum's original proof-of-work (PoW) system, the beacon chain coordinates validators, manages staking, and oversees the consensus process that keeps the network secure. Launched in December 2020, it became the heart of Ethereum’s transition to a more scalable, green, and decentralized infrastructure.
The beacon chain was developed to manage validator selection, track consensus, and introduce protocols for network upgrades. It monitors the integrity of transactions and ensures the network is robust against attacks or failures. Since the Ethereum mainnet merge (September 2022), all new ETH blocks are secured via the beacon chain’s proof-of-stake processes—marking a major milestone in Ethereum's evolution.
💡 Pro Tip: Proof-of-stake drastically reduces energy use compared to PoW, making Ethereum more eco-friendly and future-ready.
Beacon Chain vs. Ethereum Mainnet
Prior to the merge, the Ethereum mainnet processed transactions using proof-of-work, while the beacon chain operated in parallel, focusing on staking and validator coordination. The mainnet merge combined these two chains. Now, the beacon chain is the consensus engine securing the entire Ethereum network—eliminating PoW mining and fully embracing PoS. This enables better scalability, higher security, and sustainable growth.
Consensus & Epochs
Consensus is how the network agrees on the validity of transactions and blocks. In Ethereum's PoS, validators propose and attest to new blocks. The beacon chain organizes time into periods called epochs (6.4 minutes, or 32 blocks each). Within an epoch, validators are shuffled and selected at random to propose blocks and confirm transactions, keeping the system both secure and decentralized. Honest validators are rewarded with ETH, while malicious or offline ones risk penalties.

Understanding Ethereum Staking and BETH
Ethereum staking lets anyone lock up ETH on the beacon chain to help secure the network while earning rewards. Instead of mining with hardware, users become validators or delegate ETH to pooling services, contributing to consensus in a sustainable way.
But staking isn’t always liquid: standard ETH staking locks assets until protocol upgrades or payout windows. That’s where Beacon ETH (BETH) comes in—a liquid staking token that represents staked ETH, giving users flexibility, access to DeFi, and more.
Other leading liquid staking solutions include stETH (Lido), rETH (Rocket Pool), and cbETH (Coinbase). Each offers unique trade-offs in yield, redemption, and DeFi integration.
How ETH Staking Works
To stake on the beacon chain, you:
- Deposit a minimum (32 ETH for solo validator; less for pools) into the smart contract
- Either run validator hardware/software or join a staking pool (like OKX)
- While staked, your ETH helps validate transactions and maintain network security
- Earn rewards (~3-5% APR, depending on network conditions) for honest participation
- Risk penalties (slashing/inactivity) if your validator acts maliciously or goes offline
Liquid staking removes the lock-up pain: instead of waiting for unlocks, you get BETH (or stETH, rETH) representing your staked ETH, which you can freely trade or use in DeFi.
💡 Pro Tip: Staking with trusted pools like OKX means you don’t need to worry about running your own node or the risk of key management errors.
BETH vs. Other Staked ETH Tokens
| Feature | BETH (OKX) | stETH (Lido) | rETH (Rocket Pool) | cbETH (Coinbase) |
|---|---|---|---|---|
| Yield (as of 2024) | ~4% | ~3.8% | ~3.7% | ~3.5% |
| Liquidity | High | Very High | High | High |
| Instant Redemption | No (queues) | No (queues) | No (delay) | No (delay) |
| Integration | Strong on OKX | Leading in DeFi | Strong in DeFi | Good in CeFi/DeFi |
| Security/Proof-of-Res. | Yes | Partial | Yes | Yes |
On OKX, users can earn BETH automatically by staking ETH, with clear tracking, instant integration to OKX’s DeFi services, and full liquidity for portfolio management.
How Consensus Works on the Beacon Chain
Consensus on the beacon chain is achieved through proof-of-stake, with thousands of independent validators working together. Here’s how it works at a glance:
- Block Proposals: Validators are randomly chosen to propose new blocks. Others attest (vote) on the validity of these blocks.
- Epochs & Validator Rotation: Every 6.4 minutes, an epoch ends. Validators are shuffled to new roles, preventing collusion and strengthening decentralized security.
- Finality: After enough confirmations (attestations), blocks become irreversible, ensuring no double-spending or rollbacks.
- Penalties: Malicious, offline, or underperforming validators are penalized through slashing (loss of staked ETH) or inactivity leaks (progressively lower rewards), keeping the system honest.
OKX goes the extra mile to monitor validator performance, using advanced infrastructure and rapid alerting so that user-staked ETH always participates safely in network consensus.

Security, Decentralization, and the Beacon Chain
Security lies at the core of the beacon chain's design. Moving to proof-of-stake security reduces energy usage yet keeps the network robust. Here’s how that security is delivered:
- Finality & Randomness: Once blocks are finalized, history can’t be rewritten. Validator selection is random, making targeted attacks nearly impossible.
- Validator Rotation & Slashing: Regular rotation among thousands of validators, plus slashing penalties for dishonesty, discourages attacks or collusion.
- Decentralization: The beacon chain supports hundreds of thousands of validators, avoiding central points of failure. Decentralization lowers the risk from any single actor or pool controlling too much power.
Risks that remain:
- Slashing: Improper validator behavior can result in losing staked ETH.
- Smart Contract Risk: Bugs in staking contracts or third-party protocols could impact funds.
- Centralization: Pools with too much stake might threaten diversity.
OKX stands out with strict risk management—offering:
- Proof-of-reserves: Users can verify that staked ETH and BETH are truly backed on-chain.
