Re: Configure Bitcoind to NOT relay 0 fee transactions

Here is what I found after a quick check:

Look for this code in main.cpp

Code:

// Note: if you modify this code to accept non-standard transactions, then
   // you should add code here to check that the transaction does a
   // reasonable number of ECDSA signature verifications.

   int64 nFees = tx.GetValueIn(mapInputs)-tx.GetValueOut();
   unsigned int nSize = ::GetSerializeSize(tx, SER_NETWORK, PROTOCOL_VERSION);

   // Don't accept it if it can't get into a block
   if (nFees < tx.GetMinFee(1000, true, GMF_RELAY))
   return error("CTxMemPool::accept() : not enough fees");

and change to this:

Code:

// Note: if you modify this code to accept non-standard transactions, then
   // you should add code here to check that the transaction does a
   // reasonable number of ECDSA signature verifications.

   int64 nFees = tx.GetValueIn(mapInputs)-tx.GetValueOut();

   if (nFees == 0)
   return false;

   unsigned int nSize = ::GetSerializeSize(tx, SER_NETWORK, PROTOCOL_VERSION);

   // Don't accept it if it can't get into a block
   if (nFees < tx.GetMinFee(1000, true, GMF_RELAY))
   return error("CTxMemPool::accept() : not enough fees");
