Я тут гдето читал, что Крипту можно верить!
Верить можно, но лучше перепроверять, благо он, Крипт, всегда приводит цитаты или ссылки.
Раз уж речь зашла о верить/неверить, ссылках и цитатах.
Как-то я
цитировал слова одного из трёх основателей Ёты - профессора математики Сергея Попова:
Serguei Popov честно и без логических софизмов признаётMicah Zoltu [4:03 AM] ... a selfish miner's goal is to make his tip _most-likely_ to be selected by others while also (if possible) not selecting anyone else's tips.
... So, the question is, is there a tip selection strategy that a miner can take such that he will bias tip selection of the common strategy actors towards his tips without having to include anyone else's tips in his selection.
... someone could release such a client to high-hash-power individuals that would yield same rewards if no one else uses it, and _better_ rewards if others _do_ use it.
Выше в цитате синим текстом Сергей отмахивается ("
the gain from this won't be so large") от этой возможности, но я, например, эвристически совершенно убеждён, что такой (повышающий шансы подтверждения своих транзакций) модифицированный ёто-клиент будет пользоваться не маргинальной, а широкой популярностью. Хотя, в конечном счёте, в соответствии с "
Трагедией общин" и запутает
пастбище Путаницу в совсем путанное состояние.

отвечал на этот контраргумент другой эвристикой (шахматного блица):
Serguei Popov [3:21 PM] re:"selfish is to get fast confirmation, so ppl will go to use that selfish client" - What he proposed so far as "selfish strategies" would actually lead to slower confirmation times for the one who uses them, not faster. The basic idea is: if you want to be accepted by others, do what they expect you to do. You know there is a complicated probability distribution on the set of tips, according to which the "honest" nodes choose their tips to reference. This probability distribution is effectively concentrated on "good tips", but there seem to be no way to discover which tips are (slightly) better other than running the MCRW many times. However, if a node is so selfish that he wants to really reference the tips whose weight (according to that distribution) is maximized, he would need to run MCRW really many times, and even then the gain would be marginal. However, running MCRW many times requires time/resources; after you spend some time on it, the state of the tangle will already change, so you'll have to start anew. In a way, it's like playing blitz in chess: if you want to win, you don't have to always play best moves; you need to play (reasonably) good moves, but fast ...
в хорошем смысле - Это ж Помогло
