Provable Solvency Report #70 – January 2020

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 70th monthly Provable Solvency Report with step-by-step validation instructions for your convenience.

As of today, Coinfloor holds a total of 3,815.4219 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 3,819.3338. 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.

Key Pieces of information:

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_20200120.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/b18053a66d1f0577231662596059f39e0bedaaa7fd42942a51e7e1c65a19c0906

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 (1579519456) and your API authentication cookie.

Example (Linux):

    timestamp: 1579519456

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

    command: echo -n ‘15795194569BTa7M0Z/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,

Ripple CEO Brad Garlinghouse Explains Why CBDCs Don’t Threaten XRP

Ripple CEO Brad Garlinghouse Explains Why CBDCs Don't Threaten XRP

Advertisement &  & 

In a recent tweet, Ripple CEO Brad Garlinghouse continues to bolster the opinion that digital assets like XRP aren’t threatened by Central Bank Digital Currencies (CBDCs), but rather, convinced that XRP would be that bridge amongst different CBDCs.

XRP, The Facilitator

Brad Garlinghouse of Ripple some few hours ago further buttressed the point highlighted in the Ripple Insight’s latest newsletter that CBDC is one thing, interoperability amongst different CBDCs is another. And if any project isn’t thinking of how these various projects will work together, it’s just basically “re-building the same siloed system.”

Many countries and their central governments are looking into issuing central bank digital currencies for its citizens. China seems to be leading the pack as it reported that it could launch its sovereign digital currency later this year.

In the U.K. earlier this year, Sarah John, Bank of England’s Cheif Cashier, had said that there’s a need for central banks around the world to start talking about central bank digital currencies. She says this is a “crucial” need.

In another speech, the Bank of England’s governor, Andrew Bailey, said that CBDCs are beneficial.

With all these talks and plans ongoing in several parts of the globe, Brad Garlighhouse is optimistic that RippleNet’s On-Demand Liquidity service, which uses the XRP digital asset, will be a bridge amongst these currencies as it provides real-time transactions across multiple global markets.

Most Americans Don’t Like The CBDC Idea

Having a CBDC may be a good cause, but Americans don’t seem to like the idea of a “digital dollar.”

A survey carried out by Genesis mining shows that out of 400 participants, just 25% nods to a digital dollar idea. The rest associate digital currencies of any kind to be a medium for criminal activities and do not think it should replace paper notes.

Bitcoin Always Online In Venezuela: Launched The First Satellite Node In Collaboration With Blockstream

Published

on

Bitcoiners in Venezuela don’t need the internet to send some Satoshis. Today, the crypto payments startup Cryptobuyer announced the successful launch of the first Bitcoin satellite node thanks to a collaboration between Cryptobuyer, Blockstream, and a team led by a crypto enthusiast named Aníbal Garrido.

The initiative allows interacting with the Bitcoin blockchain without the need of an internet connection. A satellite antenna installed in Venezuela is in charge of the communication between the node and the blockchain.

How the Satellite Node Works

This novel solution allows the Venezuelan node to process information in real-time completely off-line. Thus, the normal functioning of the network in case of connectivity failure (something widespread in the country) is guaranteed. It also facilitates the use of cryptocurrencies in remote places where internet service is scarce, expensive, or even non-existent.

The project works as follows: Blockstream contracts a number of satellites to provide the communication service between the nodes and the blockchain. Cryptobuyer bought the necessary equipment to receive the signal and connect to the satellite, and Anibal Garrido and his team were in charge of assembling the antennas and making the required adjustments.

For Alvaro Perez, a software programmer from Valencia City who helped set up the whole infrastructure, the node’s synchronization was an inspiring moment. In statements compiled by Cryptobuyer on an official blog post, the expert says that the operation was a “great achievement.”

“We downloaded the whole Bitcoin blockchain and successfully carried out the first transaction through a Bitcoin satellite node in our country on September 23, from the city of Valencia (…) We received bitcoin through the satellite connection without any internet connection. It was a moment of great achievement.”

The journey is just beginning for Bitcoiners in Venezuela

This would be the first of three antennas that Cryptobuyer plans to deploy to cover the country’s most critical areas. The remaining two will be placed in the country’s capital, Caracas, in the north of Venezuela, and Puerto Ordaz, an industrial city located south of the country.

Later on, they plan to deploy a large number of small devices that will serve as a sort of repeater antenna to create a sizeable mesh-type network that will facilitate transactions in Bitcoin even far away from the primary antenna.

Now there’s no excuse to start using some satoshis in the country. Venezuela keeps proving that it has plenty of reasons to be on the podium of the three countries with the most adoption of Bitcoin around the world.

KuCoin’s CEO: The $150 Million Hack Is “Small” For KuCoin, Insurance Will Cover

Published

on

In a dedicated live stream, KuCoin’s CEO noted that although why he cannot reveal how much of the company’s total assets were affected during the hack, the stolen fund amount is “small for KuCoin.” The exchange will cover all the losses with its insurance fund.

  • The company first noticed the abnormalities at 2:51 AM, Sept 26, when it received an alert from its internal risk-monitoring system. More alerts followed, indicating abnormal transfers from the hot wallet.

  • At 3:01 AM, the exchange received an alert about its remaining balance from the monitoring system. Three minutes later, more alerts came in showing abnormal XRP withdrawal, which was followed by another alert that the company’s hot wallet is “running out of balance.”
  • Subsequent alerts between 3:05 AM and 3:40 AM showed abnormal BTC withdrawal alongside other tokens.
  • While the abnormal withdrawals were ongoing, the company set up an urgent task force and then shut down its wallet servers. However, the shut down did not do much to stop the hackers as the abnormal transfers continued.
  • At this point, KuCoin realized that the private keys of its hot wallet had leaked. The company then started moving the remaining balance in its hot wallet to cold storage at 4:20 AM. The process took about 30 minutes to complete.
  • Lyu said the exchange would publish the addresses used by the hackers on its official channels. An earlier report on the hack shows that the Ethereum address supposedly used for the operation contained over $150 million in ETH and ERC-20 tokens.
  • KuCoin is now in contact and working with the international police, its largest clients, and industry experts for an in-depth investigation into the incident.
  • The CEO also said they had asked most crypto exchanges, including Binance, Bitfinex, OKEx, BitMEX, and Houbi Global, to blacklist the hackers’ wallet address and assist with the investigation.
  • The crypto community was quick to swing into action to assist KuCoin in its request. Bitfinex CTO Paolo Ardoino said they have already frozen 13 million USDT on EOS that was part of the hack, while Tether froze the 20m USDT on Ethereum in the ETH address used for the hack.
  • While trading services are still available, withdrawals and deposits will remain closed until the exchange completes its wallet upgrade.
