Mielenkiintoinen artikkeli bitcoinien turvallisesta säilyttämisestä. Charlie Shremin ratkaisu kertoa tuosta sormuksesta on mielestäni hieman kyseenalainen.

Vaikka sormuksen salainen osuus olisikin eri tavalla toteutettu kuin hänen kertomuksensa (joka on toivottavaa), tämä lisää silti riskiä että joku yrittää $5 wrench attackia ([http://xkcd.com/538/](http://xkcd.com/538/)). Hänellä ei ole mitään “plausible deniabilityä” tälläisessä tilanteessa, koska nyt kaikki tietävät että siinä sormuksessa on rahaa, paljon rahaa.

Miettimistä itse kullekin sen osalta, että mitä omista bitcoineista kannattaa muille kertoa.

> Two weeks ago, Charlie Shrem got hacked and robbed, Bitcoin-style. Criminals got into a brokerage account used by his transaction services company, Bitinstant, and emptied more than $12,000 worth of the digital currency out of the account. Bitcoins...

[i]"Shrem asked his father, a jeweler, engrave the private key on a ring. Yes, a physical ring he could slip onto his finger. “I took the key, and I literally called my father and said it to him over the phone,” Shrem remembers. “He wrote it down on a piece of paper. In his factory here in New York City, he has a jewelry engraver. He took a piece of silver, and he engraved it into a ring.”

Well, he engraved most of it into the ring. To add a little extra security, Shrem had his father leave out one of the digits from the private key. That’s stored in Shrem’s head — and only his head."[/i]
