Ripple's Chief Technology Officer, David Schwartz, has detailed the reasoning behind XRP's fixed supply of 100 billion tokens. The decision was driven by the need for technical precision, ensuring the cryptocurrency's divisibility for both large and small transactions. Additionally, the supply is compatible with 64-bit integers, preventing overflow errors, and is designed for human usability, being easy to remember and communicate. Currently, 60.1 billion XRP are in circulation, with 35 billion locked in escrow. On November 1, an additional 1 billion XRP will be released from escrow.
