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.
Prodavač, koji vidi da sam poslao, siguran je da mi može  poslati proizvod, a kada bih ga primio najmanje dvoje od troje ljudi  uključenih u transakciju -- prodavač, kupac, administrator stranice -- moraju potpisati transakciju jedinstvenim digitalnim potpisom, nakon čega se vrši prijenos novca.
