# Technological Foundation ### Built on Solana After considering various blockchains, Solana was determined to be the optimal choice due to its competitive fees and exceptional performance. #### i. Transaction Fees ISC needs to keep fees below one US cent to make it affordable for small transactions. Solana’s fees are currently at $.00025 per transaction, significantly below one US cent, and expected to stay low. This ensures that ISC can function as a international currency for everyone and is not prohibitively expensive to use for everyday purchases. #### ii. Speed Solana's block time is just 0.4 seconds, enabling near-instantaneous transactions. By contrast, Bitcoin's block time is 10 minutes and Ethereum's 12 seconds. Users cannot afford to wait that long for transactions to process, especially in real-world scenarios. #### iii. Scalability With a theoretical maximum processing capacity of over 700,000 transactions per second on standard gigabit networks, Solana is capable of handling the high transaction volume that ISC requires. Furthermore, its architecture allows for even greater performance on higher capacity networks, meaning that it can process ISC transactions at scale. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
