Smart contract functionality A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. A well-crafted smart contract on the BNB blockchain platform will ensure the platform's entire security, which is the most critical point in our choice. Transaction cost Cost-effectiveness is a feature our team considered nearly at first because low transaction fees could influence broader adoption of the fan tokens and NFTs especially. We picked BNB because it fully satisfies our needs. Transaction Speed When a blockchain platform with poor throughput is employed, for example, users will be required to pay greater fees to miners in order for their transactions to be prioritized over others. Therefore, talking about cost and transaction fee, we tried to make a balance. Security Our team planned to pick a blockchain platform with a proven track record of preserving a secure history of peer-review and mining-free consensus processes, such as proof of stake, to ensure no security breaches (PoS). That's why we chose BNB Chain. Scalability On the blockchain, scalability refers to a platform's capacity to process a large number of transactions per second (TPS). Through the use of BNB, Sport Investing platform users will be able to make fast and cheap transactions within the platform, buying and selling fan-tokens of their favorite athletes.
