Hackers Still Targeting Hal Finney’s Family Over Satoshi Nakamoto
Fran Finney, wife of the late Bitcoin legend Hal Finney, said her Twitter account was hacked by someone claiming to have information on the identity of Satoshi Nakamoto. Although the incident was minor, it’s not the first time bad actors have targeted the Finney family.

Me gusta lo que dice sobre Hal Finney: "Strong candidate for Satoshi". Siempre ha sido mi opción número 1

Seguramente Satoshi es un grupo: Adam Back-Nick Szabo-Hal Finney-(otros)

If you have a read of Hal's RPOW ( reusable proof-of-work ) the idea is that once energy has been used to create an object ( in this case, bitcoin ) then that energy can be reused by transferring it into other forms ( example: XCP/ XCPC )

The first first law of thermodynamics is used to transfer electrical energy into bitcoin.
So using burning to change that object into something else is pretty fundamental to the technology itself.
I don't think there should ever be a "one-off" burning.

Hal's website is where proof-of-work was first described clearly enough.

If anyone is into the Bitcoin tech ( and counterparty is on top of that tech ) then Hal's website is a much-read

You could effectively remove every single reference in the Bitcoin white-paper and replace it with a link to Hal's website.
It's that important.

Una joya historica del 2009, espero que conozcais a Hal Finney la primera persona que recibio una transaccion de Satoshi. https://twitter.com/halfin/status/1153096538

Satoshi es Hal Finney, es Wei Dai, es Adam Back, es Nick Szabo, y es toda la gente que desde finales de los 70 estaba trabajando la criptografía de doble entrada para buscar soluciones útiles

What is a Finney attack? Extra points for explaining its purpose, the prerequisites for it to be possible, how the attack can be performed and the origin of the name "Finney attack".

The Finney attack is named after Hal Finney, who suggested it in this comment. (Hal happens to be the first recipient of a Bitcoin transaction, and the first person to comment on the release of the Bitcoin source code.)

It is a double spending attack with the following features:

It only works if the merchant accepts unconfirmed transactions.

It still works, however, if the merchant waits a few seconds to verify that everyone in the network agrees he was paid.

It requires the attacker to be mining and controlling the content of his blocks; however, he can in theory do this with any hashrate, in particular significantly less than 50% of the network hashrate.

It proceeds as follows:

The attacker mines blocks normally; in the block he is trying to find, he includes a transaction which sends some of his coins back to himself, without broadcasting this transaction.

When he finds a block, he does not broadcast it; instead, he sends the same coins to a merchant for some goods or service.

After the merchants accepts the payment and irreversibly provides the service, the attacker broadcasts his block; the transaction that sends the coins to himself, included in this block, will override the unconfirmed payment to the merchant.

If the time from finding the block until the attacker sends payment and the merchant accepts it is t, and the average time to find a block is T, there is a probability of t/T that another block will be found on the network in this time; in this case the attack will fail, and the attacker will lose the block reward of B.

This means that the average cost of attempting the attack is about (t/T) * B; as a rule of thumb the merchant should wait at least t=V*T/B (V is the value of the transaction), to make sure that trying to carry out this attack against him isn't profitable; this may not be sufficient though, as a nimble attacker can use the same block for multiple attacks, potentially gaining the total of their value.

Clearly, the lower the attacker's hashrate, the less opportunities he has to carry out the attack. If the attack is for obtaining some illiquid good, it is difficult to make the need for this good coincide with finding a block. If the attack is for obtaining something liquid (e.g. exchanging bitcoins for other money), an opportunity is ever-present but the merchant is likely to require a few confirmations. This makes the attack difficult to use in practice.

Fue Hal Finney el que dijo que un atacante malicioso podría incluir una transacción de A a B (direcciones que controla) en un bloque, y meter en el mismo bloque una transacción de A a C (que no controla). Si aceptásemos 0 confirmaciones, la transacción de A a C la aceptarías pero nunca se produciría. Eso es lo que se conoce como "ataque Finney" y por eso se requiere al menos una confirmación (y lo de las 0-conf es una boutade)

Hal es una de las personas que mas admiro en el criptomundo, quien recibió la primera transacción de Satoshi Nakamoto y le ayudó en los inicios, a mejorar el codigo de Bitcoin, Actualmente criogenizado, a la espera de una cura futura para el ELA.
