According to @cryptohistory, an early long-distance communication system utilized a 5-bit encoding method (fire signals: high or low) to transmit the 25 Greek letters, sending one character at a time. Each bit represented a binary state, allowing for efficient and error-minimized message transmission over large distances. For modern crypto traders, this highlights the foundational principles of binary communication and error correction that underpin blockchain protocols and cryptographic hash functions. Understanding these historical systems can provide deeper insight into current developments in secure crypto messaging and on-chain data verification (source: @cryptohistory, June 2024).
