BSC vs. ETH — two blockchains amid a sea of others

Explaining the blockchain battle of BSC vs. ETH requires a little context. The crypto industry, as it is known, began with a single asset and underlying blockchain — Bitcoin (BTC). From there, people and groups built other assets, blockchains and applications, expanding the potential of the crypto sector as a whole and giving people new opportunities. 

Blockchain technology (or in some cases, other distributed ledger technology) is the track on which crypto assets and solutions run. Builders use this technology as the backend for decentralized applications (DApps) and digital assets. 

DApps essentially serve as programs that look similar to other programs on the frontend, touting a user-friendly interface. However, their backends run on blockchains or other distributed ledger technology (DLT). Additionally, depending on the asset, coins or tokens built on blockchains can facilitate transactions and storage of value — free of third-party involvement.

Many blockchains exist as options for developers to work with and build upon, of which Binance Smart Chain (BSC) and the Ethereum (ETH) blockchain are but two. 

Is Binance Smart Chain better than Ethereum? Is Ethereum better than Binance Smart Chain? Is the Ethereum blockchain safe? Is the BSC network safe? Learning more about both of these blockchains may help readers to develop their own opinions on the topic. 

Battle of the blockchains: BSC vs. ETH

Ethereum began as a concept paper by Vitalik Buterin in 2013 and came to life as an independent blockchain in 2015. The Ethereum blockchain grew substantially in the years following its launch, earning significant dominance as a blockchain for building. The Ethereum blockchain includes smart contract capabilities, which makes the construction of DApps possible. 

However, Ethereum scaling has surfaced as an issue, with high gas fees burdening network users during specific periods. (Gas refers to fees paid in exchange for interactions with the Ethereum blockchain.) Ethereum proved itself and dominated the crypto space, although given scalability woes, users began looking elsewhere.

In contrast, Binance Smart Chain (BSC) was launched as a parallel companion to Binance Chain (BC) — the blockchain that crypto company Binance launched in 2019. BC was constructed mainly for trading activity and less for building. BSC, in contrast, came in 2020 hosting more building functionality. 

Two particular features stick out as differences between BSC and BC. Binance Smart Chain has Ethereum Virtual Machine (EVM) and smart contract abilities, while Binance Chain does not. 

Can you send ETH to BSC? Ethereum-based DApps should be able to be set up for BSC functionality, due to the mentioned EVM capacity. Binance Bridge is a platform that allows users to move assets between cross-chains easily. ETH, also sometimes referred to as Ether, is used to pay gas fees on the Ethereum blockchain. Binance Coin (BNB) is used for gas fees on Binance Smart Chain.

Ethereum vs. Binance Smart Chain: A quick-hit rundown

History

Ethereum and Binance Smart Chain have multiple differences at a glance. One such difference, as pointed out above, is their histories. Ethereum became functional in 2015, while Binance Smart Chain took off from its starting blocks (pun intended) in 2020. 

Since Ethereum has been around longer, it is a more time-tested solution, which could potentially give builders greater confidence in the Ethereum blockchain. In contrast, though, Ethereum was built using older technology and began changing its framework with the transition to Ethereum 2.0 (more on that in the section below). 

Centralization

Another difference — the Ethereum blockchain has more participants running the chain than does Binance Smart Chain, making BSC centralized in one regard. Under a proof-of-stake authority (PoSA) mechanism, BSC has 21 network validators that run its blockchain. The list of 21 participants is composed of the largest active stakers of Binance’s BNB asset. That list of 21 adjusts every 24 hours.

However, making it onto the list of 21 as a validator does not mean you must hold and stake all the BNB yourself. Other BNB holders can delegate (and undelegate) their BNB to validators of their choice. Validators on BSC earn transaction fees (paid via BNB) from blocks they put up. Delegators earn a portion of those fees in exchange for their BNB delegation.

Alternatively, the Ethereum blockchain has countless miners running its proof-of-work (PoW) blockchain. When the network shifts over to a proof-of-stake (PoS) consensus algorithm, stakers holding a certain minimum amount of ETH will run the blockchain. 

A key difference is the point of asset requirements for becoming a validator. Becoming a validator for Ethereum 2.0 (Ethereum’s PoS blockchain, which is currently in transition from Ethereum’s PoW blockchain) requires staking 32 ETH, among other technical specifications. ETH holders can also pool their ETH with others to meet the minimum requirement, collectively becoming validators that way. 

In Ethereum’s old proof-of-work (PoW) system, anyone meeting the requirements could compete to help run the network (by solving puzzles).

In contrast, BSC requires staking at least 10,000 BNB (as well as other technical specifications) — just to become a validator candidate. From there, you then must become one of the 21 largest stakers to become an active validator.

Branding for the two blockchains is somewhat different as well. The Ethereum Foundation, a nonprofit entity, as well as other entities, helps with the Ethereum blockchain’s development. Virtually anyone can participate in helping run the Ethereum blockchain, as long as they meet certain requirements. 

Binance is a large company in the crypto industry that has multiple products associated with its name. Is BSC controlled by Binance? Anyone holding enough BNB to compete for a top spot among the BSC validator list can help run the network, so Binance does not seem to control the blockchain directly, although BSC is technically part of Binance’s ecosystem

Transaction speed and cost

Is BSC cheaper than ETH? In general, BSC has made a name for itself as a cheaper option in terms of transaction fees on-chain. Block times for Ethereum range from about 2 to 14 seconds per block, whereas BSC posts about 3-second block times, although Ethereum’s scaling development (Ethereum 2.0) could change things for Ethereum. 

However, transaction costs and speeds come with tradeoffs. BSC has a relatively small number of participants running its network but can offer faster and cheaper transactions. 

ETH 2.0 vs. BSC

Comparing and contrasting the Ethereum and Binance Smart Chain blockchains is not such a straightforward task if Ethereum 2.0 (Eth2) is considered. Ethereum 2.0 is a lengthy transition that aims to scale the Ethereum blockchain. Part of the shift to Eth2 includes moving the Ethereum blockchain to a PoS consensus. 

Will BSC overtake ETH? No one can say for certain, and answers to that question could be subjective, depending on what users seek as far as blockchain attributes and performance. 

If Eth2 development goes as hoped, the Ethereum blockchain should eventually offer much faster and cheaper network interaction, filling in its weak spots. Such a change could make a difference in the BSC vs. ETH debate. “Should I use BSC or ETH?” you may ask yourself. That is up to you, void of any jurisdictional regulatory issues. 

However, given the blistering speed at which the crypto and blockchain industry has expanded, no one knows what the next year or decade will bring. The industry as a whole went from Bitcoin, a single asset and blockchain, to a bustling industry of burgeoning technology filled with numerous blockchains in a matter of years, not decades. 

Tomorrow’s expansion could see BSC pitted against a newer blockchain, or ETH pitted in such a fashion. Two completely new blockchains that do not yet exist could spring up and become the topic of future debates. Therefore, crypto industry education, news and discussions are key components in keeping up with the fast lane that is the crypto industry.
