-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I want to build a marketplace where users can exchange bitcoin for fiat currencies without having to go through a centralized escrow or exchanger (directly user-to-user). This can be done by bitcoin multisign option (contracts) where 2 users can agree on a mediator and proceed with a transaction. The problem is: if the users don't go through a centralized escrow or exchanger and they don't add funds or add bitcoins to their accounts, how can we verify the authenticity of sell or buy postings and build a strong and accurate order book, without users being able to abuse it by posting abusive sell or buy offers which will break the supply and demand calculation for price determination. This is a real possible vulnerability since it's not a centralized system and users do not deposit funds in their accounts, you cannot verify if the user has or doesn't have the bitcoins or the fiat currency. Any suggestions? - -- U. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) iQEcBAEBAgAGBQJTEollAAoJEIN/pSyBJlsRo3UIALEKep1mK1RL5EqftvMVZVTZ b1kUu1kxkznETvgv5da6QqOYMj3LF5QTDSAuuRCxyme98hRTITxpVxnFBWi+agLl hNeJl6wlYqWLINe3oQff1HQDzfcw6BPzy2wRkQFNTjdQla6KjhJ3/lO5Q5Pgdno0 rMpc3DCmhfAxRXl36tcn/4MLo4TeBR8OzxfpZo69K89q1Hd3+Wb3QGj2hf8vVMJP HoRhgrUh78r8d24qAHpTu+qECY1DdhyTx1GPqgNT6lp7tA+2LhkjDlq4tThUtuuc LZaI36ZrbgJv6P6PlmRQIb009sHQKxHBJVwkNXEG0DNbUF8Yw9zK67nEcsEUOIc= =Cl2L -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Flow-based real-time traffic analytics software.
