Fire coin trading platform has a certain risk
the business management department of the people's Bank of China, the Beijing Municipal Bureau of finance, the Beijing Municipal Bureau of instry and Commerce and other relevant departments formed a joint inspection team to carry out on-site inspection on bitcoin trading platforms such as "fire coin network" and "currency bank", and pointed out the problems existing in the financing and currency financing of the above platforms
According to the announcement, the inspection team decided to carry out further inspection on payment and settlement, anti money laundering, foreign exchange management, information and capital security, etc. At the same time, the inspection team suggests that investors should pay attention to the legal compliance, market fluctuation, capital security and other risks of bitcoin platform transactions, and prudently participate in bitcoin investment activities 
extended information:

bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.
EVC chain (evcc for short) is the next generation of regulatory asset management platform, which integrates the fund earning ability and influence of
1 Penetrating supervision mechanism
the financial technology risk represented by fund tokenization is characterized by behavior:
insufficient compliance (not in line with financial regulations or in the fuzzy zone)
unknown scene (whether the transaction is real or not, whether there is money laundering or pyramid selling possibility)
uncontrollable data (existing supervision measures can not effectively collect the data of participants Transaction data, capital flow data, etc.)
for this reason, evcc proposes a penetrating supervision mechanism< br /> Metadata audit
the blockchain system eliminates fraud, waste and abuse by providing auditability, timestamp and non tamperability. Specific metadata should be published on evcc blockchain. At the same time, according to the law, users share the metadata of transactions with some participants (such as tax authorities and arbitration institutions), but such sharing must be agreed by users. Evcc provides the function of labeling transactions and financial activities, and exports or shares metadata according to user needs. In addition, data can be manipulated by third-party applications for specific purposes, such as financial auditing
authentication and compliance
evcc not only provides the behavior guarantee constraints for the verifier in the scope of behavior in the smart contract, but also establishes a trusted channel between the sender and verifier through trusted hardware to transmit the compliance information to the verifier, and the verifier is forced to comply with its transmission policy. This method can effectively rece the risk of customer data leakage caused by hacker intrusion
organizational autonomy and regulatory evolution
fund institutions issue fund tokens on evcc to raise funds. Autonomous organizations are specially set up for fund-raising activities, through terms and conditions parameterization of smart contract period, and even implemented by volunteers or legal standards. Items such as refunds, redistribution, dividends, and frozen payments can be executed in an autonomous organization contract. EVC will build reference libraries and contract templates of autonomous organizations for use by smart contract developers. We also hope that the regulatory agencies can form around these decentralized autonomous organizations and make self evolution
2. Hierarchical transparency mechanism
evcc can ensure the authenticity and non tampering of transaction information while ensuring privacy. Ensure that competitive and conflicting transactions in the trading chain are not confirmed. The transaction history on evcc makes use of and greatly expands the utxo model derived from bitcoin system. Utxo makes the historical "chain" between transactions possible and forms the basis of our technology
evcc's means to achieve relative privacy include:
P2P network full encryption
the anonymity of transactions is realized through the key loop and arbitrariness of automatic identity management
build the transaction with Merkel tree to allow the specified information to be disclosed
Intel's software guard extensions technology can verify transaction records and ensure privacy when transaction information is encrypted. Intelsgx is a technology of Intel, which puts a piece of non tamperable encrypted storage space in CPU. This space allows the code to be operated by a trusted person and cannot be tampered with, even in the execution environment of the computer in the fuselage. Under this unique technology, the encryption of transaction history can only be decrypted and confirmed in a secure area, which meets the requirements of fund institutions to implement hierarchical and transparent information disclosure for token holders of different levels
3. Diversified interface support
access_ Token API: the authority interface for fund institutions to issue tokens, and assign specific access after passing relevant offline qualification examination_ After token, you can obtain the authority of the registered fund organization
4. Cash dividend mechanism
you can obtain evcc through "mining". Evcc mining and mining machine mining are different, EVC means "holding money is mining". 80% of the service charge generated by the issuance and exchange of fund token shall be returned in the form of evcc, and the service charge shall be returned to EVC cycle every day
cross link protocol (evcc link)
evcc link protocol is a decentralized token transaction matching protocol. It is a free and extensible open source protocol, which can match and match different fund tokens, so as to eliminate the constraints of transaction pairs and improve the liquidity of fund tokens
features:
1. Rece the risk of the exchange and trading parties: the token is always kept in its own blockchain address, and does not need to be kept by the exchange. It can protect members from risks such as exchange bankruptcy and DDoS attacks
2. Decentralization: transaction funds are always under the control of smart contracts
3. Loop matching: more than ten orders with different types of tokens can be loop matched at one time
I think it's the best way to try hosting, because the main factors of IPFs mining are broadband and location. In fact, the household miner can't get the list at all, so it's not profitable. At present, IPFs has not been on the main network, so the mining machines are basically in the promotion stage, and the cost performance is a relatively good period of time. The future revenue of IPFs is still worth looking forward to
I don't know if the name of the mining machine is suspected of being advertised. Anyway, there is a mining machine named "153 IPFs". After comparison, it's good to ensure the intelligence of Benjin mining strategy and mining strategy (IPFs needs to adjust mining strategy)
recently, I chatted with the people in this team. I think it's reliable and the grade is not big, so I'm idealistic and energetic

EVC, Ethernet virtual connection, is very similar to PVC / SVC in ATM technology. EVC is an end-to-end concept. We can think of it as a logical pipeline. Once an Ethernet frame enters the pipeline, it will not leak unless it comes out from another opening of the pipeline. EVC can be more formally described as "an instance of two or more Unis associated"
EVC plays a very important role in Carrier Ethernet services. By building a statistical multiplexing logical pipeline in the limited network resources, the traffic can be effectively isolated. By controlling the logical pipeline and its traffic, carrier Ethernet has a relatively complete traffic control capability, This is an important feature of telecom service
chemical instry:
ethylene vinyl chloride copolymer (EVC) is a copolymer of ethylene and vinyl chloride. In 1963, it was first proced by UCC company. It was prepared by free radical copolymerization at 90 ℃ and 98.1mpa. Suspension polymerization or emulsion polymerization can also be used. The initiator is organic peroxide or water-soluble initiator
(1) EVC structure the general formula of EVC chemical structure is:
(2) performance EVC is random copolymer. It has the similar properties of rigid PVC resin, good transparency, impact, thermal stability, weather resistance and flame retardancy
EVC resin has good processability and can be used for extrusion, injection molding and blow molding of food packaging films and procts.
