Pascal is a cryptocurrency that aims to solve the problem of blockchain scalability. It claims to have a transaction speed of 1600 TPS and offers features like a simple account number (PASA) and privacy architecture. Pascal introduces a hash algorithm called Random Hash, which is resistant to GPU and ASIC mining. This algorithm promotes mining decentralization by combining hash primitives in a serial manner with a branch-heavy and recursive implementation. Pascal also utilizes a cryptographic data-structure known as the 'SafeBox' to maintain a dynamic ledger of all account balances.
