Visa, Worldpay Take Blame For Duplicate Charges On Coinbase, Reverse Transactions

Visa, worldpay take blame for duplicate charges on coinbase, reverse transactions

Visa and payment processing company Worldpay issued a joint statement on the Coinbase blog today, Feb. 17, taking responsibility for charging Coinbase customers multiple times for the same transaction.

Before admitting fault in the statement published by Coinbase today, Visa had at first shifted the blame back to Coinbase, telling the Financial Times on Feb. 16 that it had “not made any systems changes that would result in the duplicate transactions cardholders are reporting.”

However, the latest statement from Visa and Worldpay on the Coinbase blog clarifies:

“Over the last two days, some customers who used a credit or debit card at Coinbase may have seen duplicate transactions posted to their cardholder accounts. This issue was not caused by Coinbase.

Coinbase has stated the error initiated from a change of the merchant category code (MCC) for crypto purchases earlier this month, which meant that crypto payments by card would be processed as “cash advances”. Coinbase reported Feb. 15 that the extra charges were a result of Visa reversing and recharging transactions due to the MCC code change.

Visa and Worldpay write that all of the reversal transactions should have been issued, and will be reflected in the customers’ account balances within a few days. Their statement concludes:

“If you continue to have problems with your credit or debit card account after this reversal period, including issues relating to card fees or charges, we encourage you to contact your card issuing bank. We deeply regret any inconvenience this may have caused customers.”

Brian Armstrong, CEO and co-founder of Coinbase, tweeted that he was “glad to see the record set straight on this”, attaching Visa and Worldpay’s joint statement:

The credit and debit card issues on Coinbase come after a slew of major banks around the world banned credit card purchases of cryptocurrencies, and in some cases debit card purchases, starting earlier this month.

Exscudo Releases EON Source Code On GitHub

Exscudo, the all in one financial services provider, has published the public part of the EON blockchain source code on GitHub.

[Note: This is a press release.]


The source code covers the rules of consensus, emission and block confirmation. The blockchain has been developed by the Exscudo team and is focused on providing and supporting financial services. It also enables Exscudo to develop its independent products and services.

Exscudo Releases EON Source Code On GitHub

The team has published the EON peer core source code on GitHub. It shows the main structure of the system, and how EON works and interacts within itself, but it does not cover the full functionality of the node.

“We are concerned about the security of our customers and we want to protect our intellectual property”, – CEO Andrew Zimine explains, – “I wouldn’t like anybody to set up a peer network before we do it ourselves. This is why we do not publish the full information about nodes on this stage.”

However, Exscudo plans to launch the EON test network in a couple of weeks after the end of the ICO. The detailed instructions for setting up regular and master nodes will be published in June. The minimum technical requirements for setting up a node on a virtual server are the following:

  • A machine with 1 or 2 cores
  • 1-2 GB operational memory with Unix support
  • 100-200 Gb HDD.

EON uses the DePOS mining algorithm. This means that the nodes that have more coins deposited are more likely to sign a block. DePos mining is considered to be fairer for node owners, as the rewards do not depend on the power capacity of the mining equipment.

The minimum sum required for starting a node equals 25.000 EON coins. In case a user deposits more coins on the node, he raises his chances to sign a block.

The launch of the EON test network is planned for June 2017. After the blockchain is set up, Exscudo will launch its first product, the Channels mobile app. Channels is a mobile wallet and secure messenger that works on the EON blockchain. It provides for secure communication, payments, trading and money exchange.

The key features and the structure of EON are easily explained in this video.
