Provable Solvency Report #35 – February 2017

Coinfloor is a custodian of client bitcoins and we believe that we must set the industry standard for transparency and regular audits. Without proper public accountability, the industry will not be able to grow and mature. This is why we are committed to releasing a Provable Solvency Report every month. Coinfloor is proud to have the longest standing track record among bitcoin exchanges in regards to auditing.

Today we are publishing our 35th monthly Provable Solvency Report with step-by-step validation instructions for your convenience.

As of today, Coinfloor holds a total of 9,233.9805 XBT on behalf of our clients. You are invited to verify that your held bitcoins are included in this balance by following the instructions below.


What does the Provable Solvency Report include?


We started out by creating an obfuscated report of all current client balances (the Solvency Report) and then generated a SHA-256 hash of this report.

We then created a bitcoin transaction to ourselves, that includes all currently held client bitcoins, for a value of 9,245.7445 XBT and included in the output script the OP_RETURN of the SHA-256 hash of the report, proving that at the time of making the solvency report, Coinfloor held all of our clients’ XBT funds. You can verify the amount and details of the transaction in the block chain.
