Contract digital currency exchange
the security of exchanges is an eternal topic
as the gathering place of interests, the game of interests behind may create evil links. Looking back on the development history of digital currency exchange, we can see a history full of glory and darkness. Glory is that it continues to provide users with more and more trading services and categories. Unfortunately, in the early stage of the instry, there was a lack of system. Most of the traditional exchanges were highly centralized. As the vested interests, they were opaque in assets, unfair in the distribution of interests, weak in the underlying structure, backward in security technology, chaotic in currency rules, and even dark box operation. In order to promote the global blockchain instry into a healthy development state, the market urgently needs an innovative, democratic, transparent, equal, free and safe trading environment to cope with the upgrading and iteration of the blockchain instry and promote the formation of a benign competition pattern in the global exchanges
the endless events tell us that history will not forget the instrial revolution and innovation mission of the blockchain instry, but also the hope brought by the blockchain to the global trust mechanism and the beautiful vision of redefining the world. Because of this, based on our deep understanding of the blockchain revolution and our goal of making a key contribution to the global blockchain business, we are striving to "pick one from a thousand miles" the most reliable blockchain asset trading platform
as an investor in the currency circle, the big knife of asset security is always hanging on his head. We all realize that the currency circle is a place where risks gather, so we don't even have the courage to recommend investment opportunities to our relatives and friends. Not to mention the drastic fluctuations in token trading, even buying and hoarding coins in the exchange are not bold to recommend. Because in the current stage of weak supervision, many exchange accidents and security news emerge in an endless stream, which means that a careless friend's assets will be swept away. When this wave of bear market came, we saw too many exchanges go bankrupt because of poor profits. At this time, conscientious exchanges will return the token to users, but most of them will roll up the token after they declare bankruptcy. There is "Mentougou" before and "fcoin" after. At this time, users react: you want to earn the profits of the transaction, people are interested in your principal. After seeing too much news like this, I seldom recommend buying coins to friends who are interested in investing in the currency circle
until I also experienced the "312" currency disaster in 2020, fortunately, my exchange adopted the circuit breaker mechanism in time to deal with it, so that I reced the panic and cut the flesh. Until now, the market has come back, experienced the return of capital and made profits, I carefully considered recommending this exchange; In this currency disaster, LOEX Lein of this exchange took correct and timely measures to protect the interests of users, won good reputation of users, and stood the test before I really took action and recommended it to my friends
the exchange, which has been operating for two years and has kept a record of zero security failures, has captured the rigid demand of many investors: asset security since its emergence. LOEX always adheres to the principle of user first and safety first, provides users with a safe, stable and convenient digital asset trading platform, and is committed to becoming a leader in the era of digital economy
first of all, LOEX ren operates openly through smart contracts
every user's transaction can be clearly observed through the EOS browser to ensure that your transaction is real. At the same time, because your assets are no longer handed over to the official team of LOEX ren, they are put in a place called "smart contract". Public rules ensure that your assets are smart and your EOS account is free to enter and leave, which ensures the safety of your assets. This is a safe transition to decentralization
next, LOEX also has AI program automatic detection
fault handling: support cluster expansion and active / standby operation
monitoring and early warning: real time monitoring of functional moles and timely early warning of abnormal moles
operation and maintenance center: it has a complete server cluster and database maintenance platform
protection measures: DDoS protection, intelligent ban, remote disaster recovery,
risk control management
we have a cross chain hosting cooperation system
the security system cooperates with Manwu District, know Chuangyu and other well-known enterprises
we have reached in-depth cooperation with the above-mentioned well-known institutions in terms of security. The security institutions provide a series of code audit services for smart contract projects, and continue to provide security audit services after the code upgrade of the project party. At the same time, the organization team will also provide long-term safety testing services to LOEX
therefore, what LOEX can do is secure asset protection, risk screening of currency projects, and security behavior inspection of exchange users
financial management cooperates with famous Wall Street AA level quantitative team
in the future, it can make LOEX exchange more secure and reliable. LOEX cross chain hosting can bring a large number of application scenarios to customers. LOEX exchange can provide sharing depth for all partners of loex.io, so that customers can have better circulation and trading depth in the exchange, and complete safe startup.
Binance exchange, with rapid development, has become one of the top five exchanges in the world in just half a year. Unlike idcm.io, which was the first to support vhkd, binance directly issued its own token BNB and launched the exchange
advantages: large trading volume; Support multiple computers and mobile phones; Multi language support; More currencies: 99 cryptocurrencies such as BTC, ETH, LTC and BNB are supported, 235 paired trading markets are available, and the service charge is low; It's faster to recharge and withdraw money
disadvantage: they have no futures and OTC trading, and only support currency trading, and stopped the service to domestic users some time ago, so domestic users need to choose carefully. At the same time, because binance is an exchange trading platform, it cannot be traded directly with legal currency, so it needs to use other platforms to buy cryptocurrency
it's not very convenient to recharge it to coin an network. In addition, in February and March of this year, binance suffered serious security incidents and hackers' leek cutting attacks, and its security performance was questioned
extended information:
the process of digital currency trading through the platform is as follows:
(1) investors should first register accounts, and obtain digital currency accounts and US dollar or other foreign exchange accounts
(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures
(3) the trading platform will sort the buying requests and selling requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded
(4) e to the difference between the buy and sell volumes submitted by users, a buy or sell request may be partially executed
the mode of digital currency trading through operating companies is as follows: take Ruibo coin as an example, Ruibo coin is operated by professional operating company opencoin, ripple protocol was originally designed based on means of payment, and the design idea is based on acquaintance network and trust chain
to use ripple network for remittance or loan, the premise is that in the network, the payee and the payer must be friends (mutual trust relationship is established), or have common friends (trust chain is formed through the transmission of friends), otherwise the trust chain between the user and other users cannot be established, and the transfer cannot be carried out
the ranking of digital currency exchanges is from low to high, including bithumb, okxe, binance, bitmex and coin win national stations Bithumb is the largest digital currency exchange in South Korea, and also one of the top ten exchanges in the world in terms of trading volume. Its daily trading volume exceeds 13000 bitcoins, accounting for about 10% of the global bitcoin trading volume. It promises to provide the lowest handling fee in the world. Bithum accounts for 75.7% of South Korea's bitcoin market, 10% of the global bitcoin market, and 50% of South Korea's Ethereum market
note:
1. Asset security is very critical. You can distribute your bitcoin or other currencies through exchanges, online wallets, hardware wallets and paper wallets, so that you won't lose all your assets when attacked or lost by hackers. The secret key information must not be placed in the mailbox or other unsafe online software
2. Whether it is EOS, etc, BTC, LTC, or other platform currencies, in addition to bitcoin itself has been given the attribute of digital currency gold, other currencies are more related to the application and landing of blockchain instry. Pay more attention to and analyze the trend and ecological construction of blockchain instry, so as to return to the original intention of blockchain value investment, It will also be a way to avoid risks
The contract transaction of digital currency is not safe. There are still many loopholes in the digital currency trading platform, for example, the most common are the following six kinds:
1. Denial of service attack
denial of service attack is the most important attack against the digital currency trading platform at present. Through denial of service attack, the attacker makes the trading platform unable to access normally, Because users can not accurately distinguish the degree of attack, it often causes panic asset transfer, which brings some loss
2. Phishing incident
even the best technical measures at present can not make the digital currency trading platform avoid phishing attacks. Some hackers and criminals can confuse digital currency investors by means of fake domain names or fake pages, while ordinary investors can't identify the authenticity, so it's easy to cause asset losses
Many digital currency trading platforms use a single private key to protect the hot wallet. If hackers can access a single private key, they can crack the hot wallet related to the private key. For example, in the attack on yapizon of Seoul stock exchange in 2017, the attackers stole hot wallets from the trading platform twice in a year, resulting in a total loss of nearly 50% of the assets of the trading platform and eventually leading to the bankruptcy of the trading platform Fourth, e to the lack of perfect risk isolation measures, or ineffective supervision on the rights of employees, some employees who have the operation rights of the platform use internal trust to seek unjust wealth for themselves. For example, in 2016, the event of employees stealing bitcoin on shapeshift caused a total loss of US $230000 to the trading platform by stealing and reselling sensitive information to others Fifth, the software vulnerability of digital currency trading platform includes single sign on vulnerability, OAuth protocol vulnerability and so on. At present, all countries have laws requiring banks or other financial institutions to implement information security measures to protect customers' deposits. However, e to the fact that the blockchain field is still in its infancy, there is a lack of such specifications for encrypting digital assets. Therefore, it is not accidental that many trading platforms have a large number of loopholes in the absence of security constraints 6. Transaction malleability the technical supporters of blockchain often think that blockchain transactions are highly secure because they are recorded on records that are said to be unchangeable, but each transaction needs to have a corresponding signature, and the records can be forged temporarily before the final confirmation of the transaction
extended data:
rules of contract transaction
1. Transaction time
contract transaction is 7 * 24 hours transaction, which will be interrupted only ring the settlement or delivery period of 16:00 (UTC + 8) every Friday. In the last 10 minutes before delivery, the contract can only be closed, not opened
Transaction types are divided into two types, opening and closing. Opening and closing positions are divided into two directions: buying and selling:buying open long (bullish) refers to buying a certain number of contracts when users are bullish and bullish on the index. Carry out "buy open more" operation, match success will increase long position
selling pingo (multi order closing) refers to the selling contract that the user makes up for when he is no longer bullish on the future index, offsets with the current buying contract and exits the market. Carry on "sell flat much" operation, match after success, will rece long position
short selling (bearish) refers to the new sale of a certain number of certain contracts when the user is short or bearish on the index. Carry out the operation of "sell short" and increase the short position after successful matching

3. Order method
limit order: the user needs to specify the price and quantity of the order. Limit order can be used for opening and closing positions
order at opposite price: if you choose to order at opposite price, you can only enter the order quantity, not the order price. The system will read the latest competitor price at the moment of receiving the entrustment (if the user buys, the competitor price is the selling price of 1); If it is a sell, then the counter price is buy 1 price). Issue a price limit order for this counter price
4. Position
the user owns the position after opening and trading, and the positions in the same direction of the same contract will be merged. In a contract account, there can only be 6 positions at most, that is, multiple positions of current week contract, short positions of current week contract, multiple positions of next week contract, short positions of next week contract, multiple positions of quarterly contract and short positions of quarterly contract
5. Order restriction
the platform will restrict the number of single user's positions in a certain period of contract and the number of single open / close positions, so as to prevent users from manipulating the market
when the number of positions or entrustments of users is too large, the platform has the right to require users to take risk control measures, including but not limited to cancellation of orders, closing positions, etc. The platform has the right to adopt measures including but not limited to limiting the total number of positions, limiting the total number of consignments, limiting the opening of positions, withdrawing orders, forcibly closing positions, etc. for risk control

digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English, and is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

futures, whose English name is futures, is totally different from spot. Spot is actually tradable goods (commodities). Futures are mainly not goods, but standardized tradable contracts based on certain popular procts such as cotton, soybean, oil, and financial assets such as stocks and bonds. Therefore, the subject matter can be a commodity (such as gold, crude oil, agricultural procts) or a financial instrument
