BNB vs Ethereum, what is the difference?

BNB vs Ethereum is a comparison of two smart contract platforms that look alike to users. BNB Smart Chain is fully compatible with Ethereum's virtual machine, so many wallets and apps work on both. The differences lie in who produces blocks, how fast they arrive, how fees and supply work and how each network changes its rules.

How does BNB Chain vs Ethereum consensus work?

Ethereum uses proof of stake. ethereum.org says anyone who deposits 32 ETH can run a validator. Time is split into 12-second slots, and one validator is picked at random to propose each block. Validators who break the rules can be slashed. Ethereum moved to proof of stake in September 2022.

BNB Smart Chain uses Proof of Staked Authority, a mix of delegated proof of stake and proof of authority. Its docs list 45 active validators, 21 of them in a core group, chosen by how much BNB is delegated to them. Blocks arrive every 0.45 seconds, and with fast finality a block is final within about two blocks when enough validators vote.

The trade-off is openness against speed. Ethereum has a large, open validator set. BNB Chain has a small, elected one.

How do BNB vs ETH gas fees work?

Both networks price actions in gas. On Ethereum, the fee equals gas used times the base fee plus an optional tip. A simple ETH transfer uses 21,000 gas. The base fee rises when blocks are busy, and ethereum.org says it is burned.

On BNB Smart Chain, gas is paid in BNB, and BNB Chain's docs say fees are the main reward for validators. Under BEP-95, a share of each block's gas fees is sent to a burn address. The proposal set that share at 10%, adjustable by validator vote. See what are gas fees.

How does BNB coin vs Ethereum supply compare?

ETH has no fixed cap. ethereum.org says new ETH is issued to validators while fees are burned, so supply can rise or fall depending on activity.

BNB Smart Chain has no inflation, according to its docs. BNB Chain also runs a quarterly Auto-Burn that aims to cut total supply to 100 million BNB over time, alongside the real-time gas burn. BNB began in 2017 as a token on Ethereum before moving to its own chain in April 2019.

How does USDT on BNB vs Ethereum differ?

Tether lists both Ethereum and BNB Smart Chain among its supported networks. The token is the same dollar stablecoin, but each version lives on its own chain. Because the two chains share an address style, a wallet may show the same address on both. Sending on the wrong network can still leave funds stranded, as explained in what happens if you send crypto to the wrong address.

Governance also differs. ethereum.org says Ethereum changes through public improvement proposals discussed by developers, with no coin vote. BNB holders who stake can vote on on-chain proposals, such as fee changes.
