How BARR check the "proof-of-burn" - btw: nice concept.

To burn coins for BARR, first you make sure your altcoin is accepted during the current exchange period. November 1 to November 30 we are accepting Fractalcoin at .5 BARR, Keycoin at .5 BARR, and Sapience at .75 BARR.

Before you burn your coins, send us a private message here and tell us which coin you're burning, how many coins, and your NXT address.

After you send your coins to the burn address, send us another private message with the transaction id. We will verify it on the blockchain, and then send your BARR to your NXT address.

We will keep all transaction IDs in a downloadable spreadsheet so that anyone can verify them.

Please see Page 1 of this topic for the complete instructions and rules for burn exchange.

The burn address for Fractalcoin is FVAiSujNZVgYSc27t6zUTWoKfAGxc8CEW5

The burn address for Keycoin is K7D9JtQxx7rRoWGu6szLpeFQKhbSzyUbC8

The burn address for Sapience is AFmseVrdL9f9oyCzZefL9tG6UbvhPbdYzM

These burn addresses can be verified as unspendable because they return a hash with a long string of zeroes.
