Binance Smart Chain or BSC for short has become one of Ethereum's strongest competitors in 2021.
Binance Smart Chain can achieve a block processing time of 3 seconds using something called Proof of Staked Authority (PoSA), where participants stake BNB to become validators. If they propose a valid block, they will then receive a fee from the transactions contained in it. Importantly, there is no subsidy for newly minted BNB as BNB is not inflationary and its supply decreases over time as Binance regularly "coins burn".
The idea of a double chain architecture has the big goal of allowing users to seamlessly transfer assets from one blockchain to another. This way, fast trading can be enjoyed on Binance Chain, while powerful dApps can be built on BSC. The two products complement each other.
Binance Chain's BEP-2 and BEP-8 tokens can be exchanged for BEP-20 tokens, a new standard introduced for Binance Smart Chain. Without going into too much detail, the BEP-20 uses the same functionality as its Ethereum ERC-20 counterpart. In addition, the Binance Chain Wallet allows simple token transfers from one chain to another.
BSC is definitely one of the biggest competition that ETH has, even though for some weird reason ADA managed to beat BNB in the rankings, it is easily can be said that BNB is going very strong. That power comes from the DeFi world for now, but the moment there is a huge game in the BSC world you will soon realize that people will be crazy to not go into it, all we need is a good game that gets a lot of funding and a big development team, if we could achieve that in BSC then the price of BNB will go super high once again as well.
It will take time for that to happen for sure, we didn't had the next DeFi on BSC as soon as there was one in ETH neither, it took some time but eventually we got there, I assume by the start of next year we will have a game even more popular than axie infinity (or axie moving to BSC who knows?) in the BSC world making it a lot bigger than ETH world.
