Provable Solvency Report #64 – July 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 64th monthly Provable Solvency Report with step-by-step validation instructions for your convenience.
As of today, Coinfloor holds a total of 3,884.6845 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 3,886.5118 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_20190718.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/b7ca7a97eccaf4baf4c860a35bb1ffb7efd6a868167478eaee85360ac41d1fd5
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 (1563442554) and your API authentication cookie.
Example (Linux):
timestamp: 1563442554
API authentication cookie (API Key): 9BTa7M0Z/Mrk6tFMJwEkTV3BQek=
command: echo -n ‘15634425549BTa7M0Z/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

Bitcoin Halving: Definitive Guide (In Just 5 Minutes)
Bitcoin halving is often referred to as “Halvening”, it’s a formulated reduction in the reward coins offered to the miners using a predefined blockchain algorithm.
Bitcoin halvings take place once in every four – 4 years approximately, or for every 210,000 block transactions.
The process of halvening started in the year 2012, approximately after 4 years of the invention of bitcoin i.e 2008, but practically bitcoins came into play in the year 2009.
After the first bitcoin halving, the block reward of 50 bitcoins per transaction were reduced to 25 bitcoins per block or transaction, later this reward was further reduced to 12.5 and it has now fallen to 6.25 after halvening in 2020.
The main idea of halvening is to create scarcity for the coins and to control inflation, as bitcoins issuance is limited to 21 million coins as per the idea of Satoshi Nakamoto, inventor of Bitcoin.
The production of 21 million bitcoins involves 32 halvenings, we are now done with two halvenings and this might continue till or come to an end in the year 2140.
Investors from all over the world are excited and waiting for the Bitcoin price to increase, and the demand for bitcoins in the online gambling industry is high. Bitcoins are widely accepted at Bitcoin Casinos as they collect deposits in the form of cryptocurrency from their players.
To know the overview of Bitcoin Halving (Just in minutes), check out the following infographic developed by Abishai James at WinBTC.net in partnership with ACMarket.

Santiment Reveals Top 10 Ethereum Projects by Developer Activity


Despite record highs for network charges in February, development on some of the industry’s leading Ethereum based projects has continued unabated.
The research stated that development activity is an often-underrated indicator of project success. It demonstrates the ongoing commitment to creating a working product, continuously polishing and upgrading its features, and staying true to the long-term roadmap.
The research focused solely on pure ERC-20 projects that are currently committed to developing on Ethereum. It has used 30-day Github activity to track development status and action.
We’ve just released our top 10 highest developing #Ethereum-based project countdown for the month of February! Read what the fastest moving projects using $ETH tech. are working on:
1) $GNO @gnosisPM
2) $SNT @ethstatus
3) $MANA @decentraland
4) $UMA @UMAprotocol👇 (Cont’d) pic.twitter.com/ZGWkrgzHpH
— Santiment (@santimentfeed) March 3, 2021
The Ethereum Project Top Ten
At the top of the list for developer activity in February is the decentralized prediction market platform Gnosis. Despite a 28% slide in GNO token prices for the second half of the month, the Gnosis team has been busy working on the product.
Gnosis launched on the xDai Ethereum sidechain, joined the Open DeFi alliance, and launched a new collaborative grants initiative for Gnosis Safe Apps last month.
Status was the second most developed Ethereum based project with a number of updates for the open source mobile dApp browser and messenger. SNT prices hit a three-year high of $0.125 in February.
Virtual metaverse and NFT protocol Decentraland was third in the list of developer activity with a number of features introduced to improve user experiences.
DeFi synthetic asset protocol UMA came in fourth with two main focuses for the month; getting some major protocols out the door, and there was a collaboration with BadgerDAO.
Coming in at number five for developer action was Chainlink which announced the official mainnet launch of Off-Chain Reporting (OCR). This significantly improves the efficiency of how data is computed across Chainlink oracles, reducing operating costs by up to 90%, it added.
“The most immediate benefit to DeFi and its users will be a 10x increase in the amount of real-world data that can be made available to smart contract applications.”
DeFi Dominates
These were the five most developed platforms in the Ethereum ecosystem for February 2021, and they were dominated by DeFi.
Also featuring in the top ten list was Skale Network, a decentralized modular cloud for running Ethereum-based dApps. MakerDAO, which is consistently in the top ten for development, was in seventh place.
Decentralized data exchange protocol Ocean, computing sharing economy Golem, and analytics platform Santiment itself rounded out the top ten.
