Problem z przechowywaniem BTC, backupami portfela, jest coraz bardziej palący. Trzeba brać pod uwagę uszkodzenia dysków, uszkodzenia nośników, crakcerów, wyjebkowiczów i podatkowe zapędy Morawicekiego.

Chyba pojawiło się coś, co może ułatwić nam to zadanie.

BitKey is a Debian-based live distribution containing specialist utilities to perform highly secure air-gapped Bitcoin transactions. It contains a swiss army knife of handy Bitcoin tools that support a wide range of usage models, including a few very secure ones which would otherwise be difficult to perform. The system boots into one of the three available modes: "cold-offline" - for creating a wallet and signing transactions; "cold-online" - for watching the wallet and preparing transactions; "hot-online" - standard usage but less secure as the private keys are known to the computer which is connected to the internet. BitKey also provides tools for generating "brainwallets", for the most paranoid of Bitcoin users. The live CD provides a simple desktop based on the Metacity window manager with quick links to the Bitcoin tools and Chromium for web browsing.

o ile im oczywiście wierzymy... Ja zamierzam mocno to testować. Jakieś inne pomysły to zapraszam.

PS. Od pewnego czasu klienta BTC ma także, znany i lubiany Tails.

Trochę bez sensu mieć oddzielną dystrybucję do bitcoina. Ogólnie to pełne wallety są lepsze od lekkich.

"It is very much in the individual bitcoin's users rational self interest to run a full node and use it as their wallet.

Trustless
Running a full node as your wallet is the only way to know for sure that none of bitcoin's rules have been broken. Rules like no coins were spent not belonging to the owner, that no coins were spent twice, that no inflation happens outside of the schedule and that all the rules needed to make the system work are followed (e.g. Difficulty.) All other kinds of wallet involve trusting a third party server.

If bitcoin is digital gold, then using a full node is like checking that you truly have real gold instead of fool's gold. You wouldn't accept a cash banknote without checking it is genuine, the same applies for bitcoin.

Security
All these checks done by full nodes also increase the security. There are many attacks possible against lightweight wallets that do not affect full node wallets.

This is not just mindless paranoia, there have been real world examples where full node users were unaffected by turmoil in the rest of the bitcoin ecosystem. The 4th July 2015 accidental chain fork effected many kinds of wallets. Here is the wiki page on this event July_2015_chain_forks#Wallet_Advice

Notice how node software updated months ago was completely unaffected by the fork. All other wallets required either extra confirmations or checking that the third-party institution was running the correct version. A bitcoin business, like an exchange, marketplace or online store should always use a full node for security.

Privacy
Full nodes wallets are also currently the most private way to use Bitcoin, with nobody else learning which bitcoin addresses belong to you. All other lightweight wallets leak information about which addresses are yours because they must query third-party servers. The Electrum servers will know which addresses belong to you and can link them together. Despite bloom filtering, lightweight wallets based on BitcoinJ do not provide much privacy against nodes who connected directly to the wallet or wiretappers.[1]

For some use cases, such privacy may not be required. But an important reason to run a full node and use it as a wallet is to get the full privacy benefits."
