In depth
BNB Chain was created via a hard fork, or permanent divergence, of the Go Ethereum protocol (Geth). While it is quite similar to Ethereum, there are a few significant differences. [1]
The most notable difference is that BNB Chain uses a different consensus mechanism.BNB Chain uses 21 validators, which take turns producing blocks. These validators are backed by delegators who stake BNB, the native coin of BNB Chain. This consensus mechanism is known as Proof of Staked Authority (PoSA). Validators are chosen based on the amount staked, and the top 21 candidates are elected to validate.[2]
Given that the BNB Chain chain was created via a fork of Geth, it is EVM-compatible. This means you can deploy the same contracts on BNB Chain as on Ethereum [3]

Bridging LINK Tokens to Ethereum Mainnet
The process to bridge from Binance Smart Chain to Ethereum Mainnet is a bit involved.
- You must first swap your ERC677 LINK tokens for BNB bridged LINK tokens -- Chainlink Token Swap
- Once you have your BNB bridged LINK tokens, you can either send them to you Binance wallet to swap via their platform, or use additional DeFi offerings.
- If you're not interested in using Binance...
- Bridge your tokens to Gnosis Chain -- Official Gnosis Chain Bridge
- Once you have bridged your tokens to Gnosis/xDai, you will need to use the Chainlink token swap site again to swap for Gnosis/xDai LINK. -- Chainlink Token Swap
- Lastly, you can now bridge your Gnosis/xDai LINK over to Ethereum mainnet. -- Official Gnosis Chain Bridge
