Provable Solvency Report #68 – November2019

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 68th monthly Provable Solvency Report with step-by-step validation instructions for your convenience.

As of today, Coinfloor holds a total of 3,961.8415 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 3,977.5354. XBT. The output of the script also includes 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 on the blockchain.

Your API authentication cookie:
You will find it in My Account > Dashboard in the Coinfloor signed in view, in the API section (visible only for fully verified accounts).

Instructions for Validating Solvency Report:

1. Open the Provable Solvency Report file:

https://s3-eu-west-1.amazonaws.com/provablesolvency/+solvency_20191114.txt

2. Go to

https://passwordsgenerator.net/sha256-hash-generator/ or to your SHA256sum calculating application.

Copy the entire contents of the solvency report (including any leading or trailing spaces or blank lines) into the SHA-256 generator and calculate the SHA-256 hash of the report.

3. Go to

https://explorer.bitcoin.com/btc/tx/35c90fa16acd63500f3a6c06ced2547d2f020450fa5fa2e87e3a9bee5773835c

Click on the `SHOW ADVANCED` switch to view the OP_RETURN, where you will find the hash generated in the previous step matches the hash in the OP_RETURN output script of the transaction that includes all customer bitcoins.

Instructions for finding your account balance within the Solvency Report:

1. Go to

your local SHA1sum application

to calculate the SHA-1 digest of a message consisting of the timestamp shown at the top of the Solvency Report (1573730240) and your API authentication cookie.

Example (Linux):

    timestamp: 1573730240

    API authentication cookie (API Key): 9BTa7M0Z/Mrk6tFMJwEkTV3BQek=

    command: echo -n ‘15737302409BTa7M0Z/Mrk6tFMJwEkTV3BQek=’ | sha1sum

(the command may differ depending on the SHA1sum application used)

2. Find the resulting hash in the solvency report. Your balance is shown on that line in satoshi units. 1 bitcoin = 100 000 000 satoshis. For your convenience, here is a link to a bitcoin unit converter:

https://www.satoshi.24ex.com

We believe that this approach is the best way to achieve maximum accountability whilst retaining privacy for our clients. We welcome your feedback and hope that in time, other exchanges will also help safeguard client funds by providing proof of solvency reports to their users on a regular basis.

Thank you for your trust,

Update on Bitcoin Cash (BCH) and Bitcoin SV (BSV) withdrawals

Please find below an update on Coinfloor’s support of Bitcoin Cash and Bitcoin SV.

Bitcoin Cash (BCH)

As you may be aware, on 12 June 2019, we delisted Bitcoin Cash from our exchange. We would like to inform you that from 1st of December 2019, you will no longer be able to access your BCH balances and place BCH withdrawals through your Coinfloor account online and will need to contact Coinfloor Support in order to withdraw your BCH. The BCH balances you hold with Coinfloor after this date will incur a monthly hold fee and any withdrawals that are placed after this time will incur an administration fee.

Bitcoin Cash (BCH) withdrawal fees and monthly hold fees after 1st Dec 2019

Withdrawal fee will be calculated as the greater of 1% or 0.1 BCH. Monthly hold fee will be calculated as the greater of 0.5% or 0.1 BCH (excluding the month of withdrawal).


Bitcoin SV (BSV)

If you held BCH on Coinfloor on 15th November 2018 4:40:00 PM (UTC/GMT), then we will be holding an equal amount of BSV on your behalf. We are now allowing the withdrawal of any Bitcoin SV held with us. If you haven’t withdrawn your BSV by the 1st December 2019, you will start incurring a monthly hold fee and all BSV withdrawals will incur an administration fee.

To effect a withdrawal, please contact Coinfloor Support. If you have already contacted us through our support page to enquire about this previously, we will be contacting you shortly to arrange your withdrawal.

Bitcoin SV (BSV) withdrawal fees and monthly hold fees

Withdrawal fee will be calculated as the greater of 1% or 0.5 BSV. Monthly hold fee will be calculated as the greater of 1% or 0.5 BSV (excluding the month of withdrawal).
As Coinfloor has never officially supported BSV transaction processing, BSV withdrawal fees are set to a higher amount to partially cover the increased one off costs incurred by manually processing them safely.

This does not affect Bitcoin (BTC), Ethereum (ETH) or any other assets.

Please do not hesitate to contact us if you have any questions.

Updates from Coinfloor and looking forward to 2020

2019 has been a year of focus and growth for Coinfloor. At the beginning of the year, we spun out our physically delivered futures exchange with a conglomerate of Asia and US based financial institutions, to form CoinFLEX, which is delivering exceptional growth for the group.

At the same time, we have focused even more on our core mission of providing a trusted, reliable and secure service to our clients in the UK and beyond. This focus has already seen our market share increase by over 50% in the UK since the beginning of 2019. As we approach 2020, we are continuing to pursue this mission and will deliver more services to meet the growing needs of our clients.

Below is more information on some of the key upcoming updates:

Additional Information Request

To better understand the trading experience and needs of our customers and to prepare for the upcoming UK regulations required of all UK cryptocurrency exchanges, we will be collecting additional information from our clients. The additional questions are mostly multiple choice and are designed to take only a few minutes to complete. They will be asked immediately after logging in and can be skipped up until December 1st 2019.

Privacy Policy

We’ve recently updated the Coinfloor Privacy Policy structure to make the policy clearer and easier to navigate. This includes more user-friendly language, headings and useful links to relevant information.

Updates to the website user experience and new product offerings

We will be making a number of enhancements to our website to make it easier to navigate and simpler to use. Today we have rolled out an updated “My Account” section and a number of other website navigation improvements. We are also excited about the new product offerings we will be rolling out over the coming months. Keep an eye out for many more changes to the site and our services as we head into 2020.

New collaborations on university research projects

Finally, there is a distinct lack of empirical finance literature and limited understanding of cryptocurrencies by the finance related academic community. We believe that addressing this research gap will ultimately accelerate the growth of the cryptocurrency industry as a whole through the insights gained. In order to help address this, we are collaborating with a group of researchers from the Centre for Digital Finance, University of Southampton and Henley Business School, University of Reading, to conduct valuable research aimed at better understanding the characteristics of investors who trade in cryptocurrencies. If you are interested in participating in the research by taking part in a short anonymous survey (which should take less than 10 minutes to complete), please proceed to click on the link below: https://henley.eu.qualtrics.com/jfe/form/SV_6FCKz0pEr5Nf14x

https://explorer.bitcoin.com/btc/tx/33d4d4d18705a0011cba593bce3cde564a41e53c48463ca0e69838e0e1208cf1

Click on the `SHOW ADVANCED` switch to view the OP_RETURN, where you will find the hash generated in the previous step matches the hash in the OP_RETURN output script of the transaction that includes all customer bitcoins.

Instructions for finding your account balance within the Solvency Report:

1. Go to

your local SHA1sum application

to calculate the SHA-1 digest of a message consisting of the timestamp shown at the top of the Solvency Report (1560853409) and your API authentication cookie.

Example (Linux):

    timestamp: 1560853409

    API authentication cookie (API Key): 9BTa7M0Z/Mrk6tFMJwEkTV3BQek=

    command: echo -n ‘15608534099BTa7M0Z/Mrk6tFMJwEkTV3BQek=’ | sha1sum

(the command may differ depending on the SHA1sum application used)

2. Find the resulting hash in the solvency report. Your balance is shown on that line in satoshi units. 1 bitcoin = 100 000 000 satoshis. For your convenience, here is a link to a bitcoin unit converter:

We believe that this approach is the best way to achieve maximum accountability whilst retaining privacy for our clients. We welcome your feedback and hope that in time, other exchanges will also help safeguard client funds by providing proof of solvency reports to their users on a regular basis.

Thank you for your trust,

Coinfloor Team

June website design and functionality changes

Fiat Current Accounts

Last month, we launched the roll out of Fiat Current Accounts through FCA regulated partner, Enumis. These accounts allow corporate customers to access cutting edge fiat accounts with a number of features including Faster Payments, API Access, Direct Debits and Debit Cards.

Website design update

We recently made a number of updates to the website. Beyond various design and copy improvements made based on customer feedback, we also have begun an update to our trade engine order book pages. Changes include the first iteration of the new look exchange page. We have also removed the “Market Order” tab on the trade page due to the vast majority of our clients opting to use the safer “Limit Order” functionality.

Please keep an eye out for further improvements in our trading interface and website over the coming few months.

Removal of two order book asset pairs

We regularly review all of our digital asset pairings, looking at a number of factors including client demand and trade volumes. Following this analysis, we have decided to discontinue the XBT/USD and BCH/GBP order books.

These order books will be discontinued between 19:00 and 23:00 UTC on 15th
June during scheduled maintenance of the website and API.

We will continue to process withdrawals of Bitcoin Cash (BCH) as normal up until the end of July 2019. After this we will move to processing BCH withdrawals once a week until the end of September 2019. Any withdrawals that are placed after this time will be processed monthly and an administration fee will be levied.

N.B: Over the Counter (OTC) trades for BCH/GBP and XBT/USD will continue to be available.

We are very excited for you to see all the updates we will be rolling out over the next few months and welcome your feedback.

Provable Solvency Report #62 – May 2019

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 62nd monthly Provable Solvency Report with step-by-step validation instructions for your convenience.

As of today, Coinfloor holds a total of 4,121.1897 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 4,170.6431 XBT. The output of the script also includes 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 on the blockchain.
