english: The vendor, who would see that I'd sent it, would be confident that they could then send the product to me, and then when I received it, at least two of the three people engaged in the transaction -- vendor, buyer, site administrator -- would have to sign the transaction off with a unique digital signature, and then the money would be transferred.
non_english: Prodavac, koji bi video da sam ga poslao, bio bi siguran da će oni zatim moći da mi pošalju proizvod, a onda, kada bih ga primio, bar dvoje od troje ljudi  uključenih u transakciji - prodavac, kupac, administrator sajta - morali bi da zaključe transakciju jedinstvenim digitalnim potpisom, a zatim bi se novac prebacio.
