FAQ

--------------------------------------------------------------------------------

01


IS IT POSSIBLE TO CALCULATE THE TPS FOR OPBNB?

 * The TPS can be calculated. Let's take the native transfer as an example;
   usually, it takes 21k gas per transfer, and the opBNB block gas limit is 100M
   gas. That means each block can handle 100M/21k = 4761 transactions, and the
   TPS is 4761.

--------------------------------------------------------------------------------

02


HOW CAN OPBNB MAKE DAILY TRANSACTIONS POSSIBLE?

 * Below is the average processing fee for major credit cards.
 * Visa
   1.29% + $0.05 to 3.29% + $0.10
 * Mastercard
   1.39% + $0.05 to 3.29% + $0.10
 * Discover
   1.58% + $0.05 to 3.28% + $0.10
 * American Express
   1.5% + $0.10 to 3.15% + $0.10
 * If we make $10 transaction with a Visa card, it will cost around $0.179
   ($10*1.29% + $0.05). But with opBNB, it will cost less than $0.005.

--------------------------------------------------------------------------------

03


WHY IS PERFORMANCE IMPORTANT FOR GAMES?

 * Gamers typically demand highly responsive experiences. For example, imagine
   looting an in-game asset after completing a combat scenario, but then having
   to wait dozens of seconds or even minutes for the game to respond and grant
   you the item. An experience like that would make the game largely unappealing
   and frustrating to play.
 * Responsiveness and low latency are crucial for gamers. Any noticeable delays
   between a player's inputs or actions and the game's responses can seriously
   hamper enjoyment and immersion. Slow transaction times, lag, or choppy
   performance are huge deterrents for gamers looking to deeply engage with a
   digital experience.
 * For blockchain-based games, this highlights the importance of fast
   transaction speeds and throughput to enable a seamless user experience.
   Gamers expect assets, currencies, and other in-game items to be transferred
   or updated instantly - any delays due to issues with the underlying
   blockchain network could make the game unplayable.

--------------------------------------------------------------------------------

04


CAN WE HAVE A DEDICATED OPBNB FOR MY APPLICATION?

 * The ideal scenario is to have opBNB serve as a dedicated high-performance
   ledger for gaming applications, with BSC acting as a secure settlement layer.
 * In this model, gaming transactions and interactions would occur directly on
   opBNB, leveraging its fast speeds, low fees, and high throughput to enable
   responsive in-game experiences. opBNB would be tailored to the specific needs
   of gaming workloads, optimized for fast transaction finality, and support
   gaming-focused features or customizations.
 * BSC, on the other hand, would serve as a robust settlement layer for
   finalizing transactions and ensuring security.
