73L

73L refers to a cryptocurrency tipping protocol that operates on the Bitcoin blockchain, allowing users to send small amounts of Bitcoin (satoshis) as tips or donations. The name "73L" originates from the ASCII code for the letter "L," which is 76, but the protocol was humorously renamed to 73L due to its association with the phrase "73" (a slang term for "best regards" in Morse code). This playful naming reflects the community-driven and informal nature of the project.

The 73L protocol was introduced in 2018 as a way to facilitate microtransactions on Bitcoin, which traditionally has higher transaction fees compared to other blockchains. By leveraging the Lightning Network—a second-layer solution for Bitcoin—73L enables near-instant, low-cost tipping. Users can send satoshis (0.00000001 BTC) to content creators, streamers, or other individuals without incurring significant fees.

The protocol is decentralized, meaning it relies on community participation rather than a centralized authority. Users interact with 73L through specialized wallets or extensions, such as the 73L Chrome extension, which simplifies the process of sending and receiving tips. The system also incorporates a reputation-based mechanism to reduce spam and encourage trust among users.

While 73L gained popularity among Bitcoin enthusiasts and content creators, its adoption remains niche compared to larger cryptocurrency networks. The protocol’s simplicity and integration with Bitcoin’s ecosystem make it a unique tool for supporting creators within the Bitcoin community. However, its limited scalability and reliance on Lightning Network infrastructure pose challenges for broader use.
