Kraken is a US-based cryptocurrency exchange operating in Canada, [7] [8] the EU, [4] Japan, [9] and the US, and "the world's largest bitcoin exchange in euro volume and liquidity". Kraken provides Bitcoin pricing to the Bloomberg Terminal. Throughout , the Kraken exchange has suffered from DDoS attacks and performance issues. On 10 January Kraken suspended trading for over 48 hours while it performed an upgrade which was intended only to take 2 hours.

Since first opening in this was the longest interruption to service. One month before Kraken was founded, Jesse Powell had visited the offices of what was then the largest bitcoin exchange, Mt. Gox, to offer assistance in the aftermath of the first of two major hacks. Seeing how poorly Mt. Gox was run, Powell decided to found Kraken as a greatly needed alternative and to further promote bitcoin adoption into the mainstream.

Gox, when they were down for like a week, that the exchange is really the most critical piece of the ecosystem I wanted there to be another one to take its place, if Mt. Kraken launched in September with live trading after two years of development and beta testing. Initially the exchange offered trading between bitcoin, litecoin, and euro. Additional currencies and margin trading were made available to users over time, but only after critical analysis was performed, critical elements tested, and the user experience defined accordingly.

In July , Kraken joined other U. The stated aim of the committee was to establish DATA as the future self-regulatory body of the industry. In October , Kraken announced that it had discovered major flaws in the Namecoin protocol and would not list the cryptocurrency until they were removed.

Former Kraken COO Michael Gronager, during the security analysis for onboarding the new cryptocurrencies, spotted a major vulnerability in the domain registration system and a bug that left. Although the flaws were soon fixed and Namecoin was listed on the Kraken exchange, it was delisted two years later after a decline in its trading volumes.

Gox were vulnerable to at the time. In a Fortune article, CEO Jesse Powell is quoted as explaining that the vulnerability was avoided by not relying on transaction IDs alone to track bitcoin transfers: In April , Kraken became one of the first bitcoin exchanges to be listed on Bloomberg Terminal.

JADA is the first Bitcoin regulatory body with government backing. The new funding options coincided with the launch of bitcoin-GBP trading bitcoin-USD trading was already available on the exchange. In October , a collaboration was announced between Kraken and BaFin-regulated Fidor bank to create the world's first cryptocurrency bank. The stated aim of the initiative was to set up a fully regulated and licensed financial services entity and to pool financial services from different providers in the industry.

The hope was that one of the participants would step up and take the lead on the project, but since this did not happen, the project was put on hold. In May , Kraken announced the beta launch of margin trading, becoming one of the few bitcoin exchanges to offer trading on margin. Initially the maximum allowed leverage for trading long or short was 3x later raised to 5x. Six months after Kraken declared that it would not seek a BitLicense , the then newly established regulation for bitcoin businesses serving New York residents, the exchange was finally able to regain access to the North American market in January by acquiring the NY-based exchange Coinsetter.

Additionally, before the acquisition, Coinsetter had recently consolidated the Canadian exchange Cavirtex. After its public refusal, Kraken expressed an intention to return service to New York residence pending the removal of what it perceived as unfair and counterproductive licensing.

In absorbing Coinsetter, and by extension Cavirtex, the following month, Kraken opened up its platform to residence of 37 other states, and to all Canadian residence to boot. Alongside this deal, Kraken announced partnerships with payment providers SynapsePay in the U.

Just one month later, Kraken announced the completion of its Series B round of investment lead by SBI Investment, a prominent Japanese venture capitalist firm under SBI Holdings, [93] Following this investment round, Kraken announced two major acquisitions that year: Dutch exchange CleverCoin, which was acquired in June, [94] [95] and Glidera, a wallet service allowing users to directly fund Glidera bank accounts with fiat for the purchase of cryptocurrencies on the Kraken exchange.

On January 5 after seeing the Monero Market cap grow over 40x in Kraken made the decision to add trading support for it. Monero was the second anonymous cryptocurrency to be added following the previously listed currency Zcash. During the acquisition they also hired the founder of Cryptowatch Artur Sapek to help integrate Cryptowatch into Krakens systems and further the development of the platform.

In December it has been reported that Kraken was registering up to 50, new users a day. In April , Kraken announced to shut its services in Japan , after operating since October , by the end of June due to the rising costs of doing business there. In November , Nobuaki Kobayashi, the court-appointed bankruptcy trustee overseeing the Mt.

Gox liquidation, announced that Kraken was chosen to assist with the investigation of lost bitcoin and the process of returning remaining funds to creditors. In April , Kraken started accepting MtGox creditor claims through its website, a process which required creditors to create a Kraken account. Creditors could also file their claim through the Mt. No date was given for when the creditors might expect to receive their share of remaining funds, but the trustee said that the date for investigating creditor claims was extended to the date of the next creditor meeting.

Thomas confirmed that the total amount of bitcoins held by Kraken exceeded the amount required to cover the list of account balances he was given.

The Merkle tree method allowed Kraken clients to cryptographically verify that their account balance was included in the list of balances audited by Thomas. To discover the measures taken by cryptocurrency exchanges to fight bots, manipulating the market, and stopping money laundering, New York Attorney General Office started an investigation. This fact finding investigation is based on a questionnaire that is going to find out how the cryptocurrency exchanges exactly work and how do they protect their customer investments.

This investigation was not welcomed by the CEO of Kraken, Jesse Powell, who declares the investigation as hostile and bad for business.
