Auditor

The code in this repository is subject to rolling changes.

Withdrawals

Each participant in the voting pool will operate three physically distinct servers -

• Transaction Server
• Auditing Server
• Key Server

The auditing server audits the OT receipts in real time of all the other participants, particularly looking for transactions indicating that a customer wishes to withdraw bitcoins from the pool. The act of sending an OT receipt for BTC back to the issuer should include a method of indicating the blockchain address to which the withdrawals should be sent.

When the auditing server detects a valid withdrawal request on its own transaction server it creates the appropriate bitcoin transaction and passes it around to the other auditing servers for signing. When it detects a valid withdrawal request on another transaction server, it stands by to sign the withdrawal transaction.

Withdrawal requests are processed using unspent outputs in the hot series without regard for which server originally accepted a particular deposit and which server’s user is requesting a withdrawal.

Bootstrapping

Phases of Development

1. Communications

   Audit Servers should be able to communicate to eachother through BitMessage (optional), and should also be able to communicate with OT Servers.

2. Funds

   Audit Servers should be able to process test funds, Deposits/Withdrawals. They should be able to communicate the status of these funds to other Audit servers in the pool.

3. Pool Integrity

   The integrity of the pool should be able to be tested by removing Audit servers and OT servers at-will.

4. ...

Altering Pool Members

Altering the pool (adding, removing, or replacing members).

Actions

• Adding Funds to Pool
• Removing Funds from Pool
• Check for Inflation
• Adding Members
• Removing Members
• Replacing Members

Dependencies

• xmlrpc-c (on OSX, compiled with "CXXFLAGS='-std=c++11 -stdlib=libc++' ./configure --enable-libxml2-backend; make -j2")
• libxml2
• boost >= 1.54.0

Known Issues

• If you are getting errors such as "API Error 0021: Unexpected API Failure - need more than 0 values to unpack", that means xmlrpc-c and auditor were not compiled with the same standard library. Also make sure that you remembered to use "--enable-libxml2-backend" when running "./configure" on xmlrpc-c.

Definitions

• Funds -

• Pool - A group of independent Open-Transactions transaction servers who cooperate to store outputs on the Bitcoin blockchain in order to provide full backing for bitcoin-denominated receipts.

• Multisig - A type of bitcoin output script which uses OP_CHECKMULTISIG as described in BIP11.

• Inflation -
