Hal Finney Cryonics Research Fund

The Hal Finney Cryonics Research Fund (HFCRF) was founded by the Alcor Life Extension Foundation in 2018. Named in honor of cryptocurrency pioneer Hal Finney, the fund aims to advance the technology behind cryopreservation for future revival. The fund was established through a $5 million donation by Alcor member and cryptocurrency entrepreneur Brad Armstrong.

In April 2018, Armstrong's assistant called to say that Armstrong wanted to make a major contribution to Alcor for the purposes of cryonics research. Armstrong's cryptocurrency contribution was made by transferring it to an intermediary organization. Formally, the funds were received from the Against Aging Fund at East Texas Communities Foundation. The donation was in the form of the cryptocurrency Stellar. As of 2021, it is Alcor's largest ever research donation.

Research projects
The fund is focused on research to advance the cryopreservation of brain tissue or whole brains, or advance the clinical practice of cryonics, including patient stabilization, transport, and cryopreservation practices.

As of 2021, these research projects have been funded through HFCRF:
 * Blood–brain barrier modifier research
 * Universal Data Logger (UDL)
 * Cooldown Fault Alarm System (CFAS)
 * Revival from Human Cryopreservation Using Nanorobotics
