"Hal was far more the anarchist than I could ever imagine. I had many in my circle who were anarchist in nature, and I didn’t really think about the utopian goals they held and problems they could cause later on. Hal wanted people to run nodes early on. He is the reason that we had a block cap. I knew that I should have fought back and not have allowed it."

"One experimental "information market" is BlackNet, a system which appeared in 1993 and which allows fully-anonymous, two-way exchanges of information of all sorts. There are reports that U.S. authorities have investigated this because of its presence on networks at Defense Department research labs. Not much they can do about it, of course, and more such entities are expected."

5. "Anyone a Mint"

Recent work by Ian Goldberg of UC Berkeley, and similar work by Doug Barnes, Hal Finney, and others, makes a truly anonymous digital cash system possible. Goldberg's scheme allows "e-cashiers" and "e-moneychangers" to disintermediate the process and ensure untraceability. Importantly, anyone can essentially become a "mint" of digital cash...."

HAL FINNEY

Harold Thomas Finney II was a genius cryptographer, hired by Phil Zimmerman to work on PGP (Pretty Good Privacy), a military-grade encryption software. Hal created the world’s first digital currency system, RPOW (Reusable Proof of Work). Hal helped Satoshi Nakamoto debug Bitcoin’s code. He was the first to receive a Bitcoin transaction. In 2009, Hal was diagnosed with Lou Gehrig’s Disease. He died in 2014.

Subject: stealth, stego & pgp (Re: Eason/Kawaguchi stego)

On how to stego pgp messages. First you have to ensure that the data you are stegoing has a rectangular distribution with even probability
of {0,1} for each bit, and apply your stego technique. Various ideas have been discussed, but as anonymous suggests this has all been
worked out for PGP 2.x before.

As anonymous describes one problem is the RSA modulus, because RSA encrypted messages are not uniformly distributed (they are < N the RSA modulus, which gives some skew especially in the distribution of the most significant bits)

Hal Finney, and Bodo Moeller and I independently came up with different algorithms to do this. Hal's algorithm (which is the better
algorithm) is to add a random multiple of N, and then the reverse operation is to assume the recipient's public key:

" Those machines are gone now. I replaced them every 12 to 18 months. Servers were donated to a number of churches and ran email means for such organisations. A couple ran web servers. During the year I started installing machines that ran Windows XP and nodes. There weren’t a lot of machines running Bitcoin in 2009. To my knowledge, Dave ran one machine, that’s full-time, and he ran three or four on or off. Hal Finney ran a machine. Bear ran one or two."

Bitcoin and me (Hal Finney)
March 19, 2013,

Cada cierto tiempo tengo la costumbre de releer ciertos documentos, para comparar lo que comprendo hoy, con relación a lo que entendí la última vez que lo leí, evidentemente deben ser documentos originales de gente original, este es uno de esos casos, donde hoy lo que voy leyendo de Hal y las explicaciones que voy recibiendo de Craig, hacen que muchas piezas encajen.

Para evitar, que por algún motivo pueda desaparecer, dejo una copia del documento original y una traducción al castellano en la blockchain.
Buena lectura!!!!!!!

HAL FINNEY: EL PRIMER BITCOINER
Publicado por Javier Bastardo |
Abr 14, 2019 |

Nacido en California, el 4 de mayo de 1956, Finney estudió en el California Institute of Technology (CalTech), graduándose como ingeniero en 1979. Sus primeros trabajos estuvieron relacionados con los videojuegos, siendo parte del equipo de desarrollo de juegos como Astroblast o Space Attack.

Durante su carrera profesional llegó a ser desarrollador de PGP Corporation, convirtiéndose en el segundo miembro de la plantilla de desarrolladores del proyecto luego de su creador, Phil Zimmerman. Fue parte fundamental de la versión 2.0 de esta herramienta.

44:30 How Hal Finney & Ray Dillinger helped

Acabo de traducir otro artículo de los que considero, "reliquias" de la comunidad, esta vez de Ray Dillinger, un total desconocido para mí, hasta hoy, pero de una importantísima labor en los primeros momentos de la creación del software de Bitcoin, trabajando de la mano con Satoshi Nakamoto y Hal Finney a finales del 2008.

Me complace ver que no solo tenía los conocimientos, como para contribuir en el proyecto, sino los valores que siempre le he reconocido a los pioneros de la comunidad.


Si hubiera sabido lo que estábamos empezando.

On p. 7 they write:

By the time he released the paper, he had already coded the entire system. In his own words, “I had to write all the code before I could convince myself that I could solve every problem, then I wrote the paper.” Based on historical estimates, Satoshi likely started formalizing the Bitcoin concept sometime in late 2006 and started coding around May 2007.

Worth pointing out that Hal Finney and Ray Dillinger — and likely several others – helped audit the code and paper before any of it was publicly released. https://www.ofnumbers.com/category/bitcoin/

"Hashcash was also used by Hal Finney's bitcoin precursor RPOW as a way to mine coins. Wei Dai's B-money Proposal, and Nick Szabo's similar Bit Gold proposalbitcoin precursors, also were proposed in the context of hashcash mining."

Original Announcement

Reusable Proof-of-Work (RPOW) was an invention by Hal Finney intended as a prototype for a digital cash based on Nick Szabo's theory of collectibles. RPOW was a significant early step in the history of digital cash and was a precursor to Bitcoin. Although never intended to be more than a prototype, RPOW was a very sophisticated piece of software that would have been capable of serving a huge network, had it caught on.
