By the way, and you know why their puzzle addresses were removed from the 161st?
My thought is that this is the limit of public addresses. That is the further search in the theory goes on a circle.
Because all the funds from 161 through 255 were redundant (Bitcoin addresses only use 160 bits) the author of the puzzle moved all the funds from the 160-255 ranged down into the 1-160 range.  It is explained up thread.
Is it? I thought it uses almost 256 bits (the last possible private key is FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364140)

I see puzzles 65, 70, 75, 80 ... 125 are solved. How come?
It's easier to solve a key if you know the public key, when someone spends from his address, public key associated with that address is revealed, this is what Satoshi did with puzzles every 5 key apart, methods such as kangaroo and BSGS can be used to speed up the search thousands of times faster than brute forcing for unexposed puzzles.

That's why you should never keep your coins on addresses with known public keys.😉 ( not that any time soon they can crack 256 bit keys, so every one is safe for a few decades )
But maybe someday you have to make an outgoing transaction. So after this transaction you need to transfer a rest of your bitcoins to another address without any outgoing transactions to be sure that your public key is not revealed?
That's the best security precaution, think of public keys as actual keys of safe vaults, and think of hackers/ attackers as keysmith, given enough time and resources they can make a duplicate and open the vault, but if they never see the key, they can't duplicate it.
But how whales work with it? Let's choose this address, for example https://www.blockchain.com/explorer/addresses/btc/bc1qgdjqv0av3q56jvd82tkdjpy7gdp9ut8tlqmgrpmv24sq90ecnvqqjwvw97
It has a lot of bitcoins, and has no outgoing transactions, so no one knows the public key. But how the owner can withdraw some of these bitcoins without revealing his public key? This is Bitfinex verified address, and they need to operate with this money, but this money just frozen on this address, because they cannot make outgoing transaction without revealing public key.

But how can you find public key after making a transaction? Because there is only address and after that you need RIPEMD-160 and SHA-256 hashing to find out public key.

Скрипт по генерации сид-фраз, приватных ключей и адресов из полученных фраз. После этого проверяем баланс полученных адресов.
Для работы используется программа для автоматизации ZennoPoster.
Скрипт полностью бесплатный, без регистрации и смс.

Всем привет.
Решил поделиться шаблоном для автоматической настройки VPN при помощи программы Zennoposter. Затраты будут только на vps сервер, на одном сервере можно сделать множество конфигураций для подключения. Для запуска шаблона понадобится программа Zennoposter, подойдёт даже бесплатная демо версия. Сам скрипт и более подробная информация по настройке и запуску находится на официальном форуме Zennolab в разделе конкурсных шаблонов: https://zenno.link/rZyGE

На собственном vps лучше pptp и/или openvpn поднять и не мучаться проксями Wink

В некоторых случаях целесообразнее и рациональнее использовать именно прокси.

Всегда можно придумать "некоторые случаи". В подавляющем большинстве случаев, vpn удобней.

Опять же смотря для чего это использовать. Если необходимо для автоматизации каких-либо процессов, где нужна уникальность, то vpn не подойдёт, потому что нужна именно пачка проксей.

Решил поделиться шаблоном для получения своих собственных https/socks5 прокси при помощи программы Zennoposter. Затраты будут только на vps сервер, что в некоторых случаях будет даже дешевле, чем покупать прокси в сервисах, а по качеству свои прокси будут явно лучше, чем непонятно во сколько рук отдающихся через сервис.

Довольно рискованно, работник должен иметь выбор. Потому что есть риск получить сегодня 100$ а завтра они превратятся в 10$. Ну или наоборот.
