Hong Kong cryptocurrency exchange Gatecoin is not to support SegWit2x

A popular Hong Kong cryptocurrency exchange, Gatecoin, announces its plans regarding SegWit2x hardfork. According to the company, it will not be supporting the upcoming SegWit2x (B2X) har fork in November "due to the lack of two-way transaction replay attack protection coded into this proposed software upgrade”.

As detailed by the exhchange, not supporting B2X means that Gatecoin will:

  • NOT distribute any B2X to the clients
  • NOT process any B2X sent to the Bitcoin wallet addresses
  • NOT list any B2X coin on the exchange

Therefore, Gatecoin clients hoping to claim newly minted B2X coins equivalent to their Bitcoin holdings at the time of the hardfork, will need to withdraw their Bitcoin from the exchange at least 12 hours before the hardfork occurs at block 494,784 (expected sometime in November, exact date TBC).

We will however be running B2X nodes in case the software’s developers decide to add replay attack protection in the future.

The company also sheds light on the two-way transaction replay attack protection, that prevents you from “double spending” your coins after the hardfork. Thus, without replay protection, new transactions will be equally valid on both the Bitcoin blockchain and the B2X blockchain as they will be identical to one another. This means that any new Bitcoin or B2X transaction can be copied or “replayed” from one chain to the other, hence the term “replay attack.”

To prevent this from happening, B2X should update their software so that new transactions are valid on one chain but not the other. This would be known as replay attack protection. For instance, Bitcoin Cash successfully implemented this as part of their chain split in August and is why Gatecoin was able to support it.

BitPay to Receive New York's BitLicense

The well-known cryptocurrency processing service BitPay obtained a license to work with virtual currencies in the state of New York. Known also as BitLicense, this license is issued by the New York Department of Financial Services (NYDFS) and grants its holders the ability to conduct activities related to cryptocurrencies in the state.

NYDFS has carefully studied the company's application, including its policy on measures to combat money laundering, customer identification, fraud prevention, cybersecurity. The financial situation of the company was also thoroughly analyzed.

New York state has one of the strictest policies around businesses involved in cryptocurrency and working through the approval processes to obtain a License was important to BitPay. We believe this hard work will pay off as New York presents significant business opportunities for BitPay.

CEO, BitPay

Having received BitLicense, BitPay can now conduct business with New York-based companies and consumers: the first will be able to use the company's processing services to accept payments in Bitcoin and Bitcoin Cash, the latter will pay for various goods and services using these two BitPay supported cryptos.

Note that BitPay was only the eighth company that received BitLicense. Other license holders are Square, Xapo, Genesis Global Trading, bitFlyer USA, Coinbase, Ripple and Circle. In addition, special permissions for operations with crypto-currencies are exchanged by Gemini and itBit.
