OKCoin International Notice Regarding BTC Margin Trading and Bitcoin Cash (BCC)

Dear users,

Starting August 1, 2017 20:20 (GMT+8), BCC (Bitcoin Cash also named BitcoinABC) will begin to be mined. In the strictest sense, BCC is an alternative asset to BTC, and is not part of or a fork of Bitcoin. We have determined that BCC has changed the original technology and security intention of BTC, by adopting the dynamic difficulty adjustment. It is in our judgement a new digital asset, but simply that BCC starts its ledger history with the same owners as that of BTC. As such this asset has granted all BTC holders the equivalent amount of BCC at the outset.

OKCoin International BCC rules for those using our margin trading service:
Because of technical complexity,borrowers and lenders would NOT be granted any BCC. If you have any questions to our policy, we suggest that you pay off in advance of August 1, 2017 20:20 and re-finance afterwards.

From our earlier notice on deposits and withdraws, we kindly remind you again:

1. From July 31, 2017 00:00 to August 3, 2017 00:00, in order to prevent replay attacks we will halt Bitcoin deposits and withdraws. In order to not interrupt your trading experience, we recommend you deposit bitcoins in advance.
2. In order to prevent replay attacks leading to a loss of either BTC or BCC, the OKCoin International technical team will be conducting extensive testing, and the resumption of deposits and withdraws may be earlier or delayed.
We endeavor to continue to provide you with better products and better services!

How OKCoin International Is Preparing For Bitcoin and BCC (Bitcoin Cash)

Dear user,

With August 1, 2017 fast approaching, the Bitcoin fork discussions have reached a feverous level. In recent days, many OKCoin International users on social media, blogs, and forums have expressed their questions and concerns about the Bitcoin fork. OKCoin International as a leading advanced digital trading platform servicing millions of users around the world want to clearly outline our policy in line with our objective to be market neutral and giving users their rightful ownership of the Bitcoin forks. Below we state our official policy for the new digital asset Bitcoin Cash (BCC).

First, the New York Agreement’s Segwit2x (BIP 91) has successfully locked in, and the current network is stable and it does not appear that there will be a fork event with UASF (BIP148). OKCoin International will continue to offer full trading support. On the other hand, BCC is a digital asset based on the Bitcoin ABC software. Bitcoin ABC has contained within its release a dynamic difficulty adjustment, does not include SegWit, and increases the block size to 8 MB. BCC will begin to be mined on August 1, at 20:20.

We believe that BCC changed the BTC technology parameters with the use of the dynamic difficulty adjustment. BCC is therefore a new digital asset, and its future development and that of BTC will be distinctly different. We wish to clearly distinguish between BCC and BTC.

OKCoin International Policy:

1. On 2017 August 20, 20:20 If you have a BTC balance, we will additionally give the same balance of BCC to your account at the appropriate time.
2. From July 30, 2017 00:00 to August 3, 00:00, we will halt deposits and withdrawals in order to prevent replay attacks. We recommend that you deposit your bitcoins in advance in order to not interrupt your trading capabilities.
3. In order to take every precaution against replay attacks leading to the loss of BCC or BTC, OKCoin International will be conducting appropriate testing and the resumption of deposits and withdraws may be ahead of schedule or delayed.

Going forward, OKCoin International will assess the state of BCC operations, its technology, the strength of its development team, market liquidity, compliance and other aspects to make our decision about supporting trading of BCC. We will take careful consideration and we thank you for your patience as we will make our announcement after August 1, 2017.

We at OKCoin International wish to continue providing you with better products and better services!

OKCoin officially launched ETC trading on July 17th

Following the July 17th launch of Ethereum Classic
(ETC) trading on the OKCoin platform, the demand for ETC has soared and ETC is
once again a hot topic within the community after a 3 year uphill battle
conceptualizing a decentralized environment.

Based on popular demand, the ETC community accepted
the user proposal to set a cap for the total supply of ETC.  The change
will happen around December with a 20% award reduction for the first 5 million
blocks and further 20% reduction every 500,000 blocks thereafter. The estimated
total supply of ETC will be 210 Million but with no more than 230 Million.

What are your views on ETC?  Are you a supporter
for ETH or ETC?  Would ETC reach new heights in July? Discuss with us here in blog or on twitter! 

Recap on ETC:

Total supply of ETC: 210 Million

Average Block Time: 60s / block

Launch Date: 2015/11/1

Consensus Method: POW

ETC in Circulation: 76,623,310

What is ETC?

The Ethereum Classic (ETC) is a
continuation of the original Ethereum blockchain, which is a new coin generated
by a Ethereum hard fork after 1,920,000 blocks. ETC functions very similar to Ethereum.
The application runs completely in accordance with the program settings,
without any possibility of downtime, review, fraud or third-party interference,
and is avoided from external interference and deliberate transaction tampering.

The concept of ETC

ETC maintains the concept of decentralization,
based on the blockchain to ensure the consensus mechanism. ETC firmly believes
that once the blockchain began to run, its developing direction will not be decided
by any centralized team, but by the consensus of the entire network participants
and the consensus of the whole network computing power.

Goal of ETC

The
goal of the ETC project is to maintain the core nature of the original Ethereum
blockchain, and to provide a new option for people who do not support DAO solution.

ETC supporters

ETC
supporters come together holding different reasons. The initial support comes
from the idealists who are faithful to the original characteristics of the
blockchain. They believe that the irreversibility of blockchain technology is
the original intention of the designer, and the decentralization and
distributed ledger are the core of the blockchain.

Another reason developers are supporting
ETC for is that compared to ETH, which is too much influenced by Ethereum
Foundation, ETC follows the basic principles of a decentralized open source
community, and it provides a freer environment for application development.

How OKCoin Is Preparing For The Potential Bitcoin Forks

Since its release in 2009, Bitcoin has
gained unprecedented global influence over the past eight years. Bitcoin’s
progress was a natural evolution of the internet. It has also ushered in new
possibilities for the evolution of our society and today counts itself as the
most reliable public blockchain in the world. Bitcoin has the potential to be
the basic infrastructure on which emergent blockchain applications are built
upon and play a major role in our new economy.

Over the recent years of rapid growth of
Bitcoin, several different development paths and proposals have emerged within
the Bitcoin community. Some have advocated for expanding the block size in
order to handle more transactions and increase network throughput. Some have
proposed introducing a new transaction format and upgrading the data structure
(SegWit) and developing second layer technologies such as Lightning Network in
order to increase transaction throughput. OKCoin is proud of and thankful for
all experts and developers for their commitment to the advancement of Bitcoin.
We believe that the fight for the future of Bitcoin have been based on
technical ideas, not on conspiracy theories, or politics amongst various
companies and organizations.

In our everyday lives, the technologies we
enjoy have similarly emerged from their own controversies and growing pains.
For example, Windows Mobile, Nokia Symbian, iOS, Android competed in the market
for years until iOS and Android become widely accepted. Similarly, today’s
China’s high speed rail network is a result of years of market competition
between different technologies such as magnetic levitation versus wheel-based
high speed trains. As for Bitcoin, we believe that market competition should be
the decider of what technology prevails, not summits or political pacts in
support of one option or another.

OKCoin as a company is dedicated to making
Bitcoin accessible, and our purpose is to serve the best interests of each and every
one of our customers. OKCoin does not and has no power to help users choose
which kind of Bitcoin technology to adopt. Our stance is that OKCoin will
support all competing forms of Bitcoin, and grant each option to our customers
and the market.

Officially, OKCoin is preparing for the
upcoming potential Bitcoin forks with the following policies:

1. During the potential fork, from
2017-07-30 to 2017-08-05, we will suspend Bitcoin deposits and withdrawals due
to potential technical risks such as replay attacks and other issues that may
cause network instability. We will further advise on specific timing but we
advise that you deposit Bitcoin in advance in order to not affect your trading.

2. If there is no fork, and the network is
stable, we will resume Bitcoin deposits and withdrawals.

3. If Bitcoin is split into several
blockchains, OKCoin will for every blockchain give users their rightful
ownership of their Bitcoin. In addition, OKCoin will take steps to support
trading for every type of Bitcoin.

4. In all these circumstances, the easiest
way for uninterrupted trading is for users to deposit Bitcoin in advance and
OKCoin will handle all resulting technical issues related to the potential
Bitcoin forks.

5. If unexpected market action occurs
during the potential Bitcoin fork period, OKCoin may temporarily also suspend
Bitcoin trading.

We believe in the years ahead, after a long
period of market competition, one or several versions of Bitcoin will be widely
adopted. Let us all work towards that future together.

OKCoin to add Ethereum trading

Dear OKCoin users,

OKCoin was founded based on a commitment to providing our users the best product, technology, and trading experience. Over the past few years, we have received frequent requests to launch a variety of digital assets on our exchange. Our stance, as a sophisticated digital asset trading platform that serves millions of users around the world, has always been to be prudent about adding new digital assets that have not been fully tested by the market.

Recently, OKCoin users have taken interest in the development of Ethereum (ETH) and Ethereum Classic (ETC), and there is an increasing demand for OKCoin to enable ETH and ETC trading. For the past two years, we have been constantly reviewing the viability of listing ETH and ETC based on factors including technical maturity, innovation, market liquidity, and compliance.

Today, we are formally launching ETH on the OKCoin exchange. Ethereum has a current circulation of 90 million, with ETH reaching a market cap in excess of USD 10 billion, and a total hashrate of more than 25K GB. Hundreds of applications are now built on Ethereum and a growing number of applications are using smart contracts run on the Ethereum blockchain.

More than 20 top global financial institutions and technology companies, including JPMorgan Chase, CME Group, BNY Mellon, Thomson Reuters, Microsoft, Intel, and Accenture, have set up the Enterprise Ethereum Alliance (EEA) to define enterprise-grade applications of Ethereum. China’s Tencent, Zhong An Insurance and other well-known companies are also investigating various applications of blockchain. The United Nations has just launched its first large-scale Ethereum test to distribute humanitarian funds.

Given this opportunity, we implore BTC Core developers and relevant Miners to work together and resolve any outstanding technical issues, activate SegWit, and solve BTC’s scaling issues. Our industry and the history of technology offers us many warnings, whether it’s the IE browser or the Nokia mobile phone. No matter how dominant, how much market share you have, if you do not adopt the latest technology and fail to constantly improve on the core user value proposition, time will pass you by. Ultimately, digital asset exchanges around the world can only advocate for the best technology and aim to provide the best trading experience for our clients.

OKCoin will officially enable Ethereum (ETH) deposit and withdrawal services on 22:00, May 31. ETH trading services will be officially available on 12:00, June 1.

We pride ourselves on excellent product and quality customer service. We at OKCoin look forward to continuing to provide you with the best trading products and services.
