Zilliqa's positioning is the bottom public chain , and its core competitiveness is to greatly improve the throughput of TPS (i.e. transaction processing speed) through fragmentation technology. In the latest experiment, the processing capacity of zilliqa test network reaches 2488 TPS, which is more than 100 times of Ethereum's maximum speed of 20 TPS and 355 times of bitcoin! Through fragmentation technology, when there are more nodes in the network, the transaction processing speed will be higher. When the number of nodes reaches tens of thousands, transaction speed is very likely to reach the speed of visa, a centralized organization zilliqa project's token name is ZIL, which has been circulated and traded on 23 exchanges. Mainstream exchanges such as fire coin and coin security support it, so it is very convenient to participate. ZIL's maximum supply is 21 billion, of which 12.6 billion will be released directly through contracts, and the other 8.4 billion will be released in the form of mining awards within 10 years

- what's the purpose of playing bitcoin
you will give 100 reasons, but the real purpose of most people is only two words: to make money<
only a few people participated in the early stage. They felt that the financial system of Wall Street was stealing itself, which triggered the subprime mortgage crisis and made Americans pay for the greed of Wall Street. As a result, they have developed a machine accounting system that is separate from the Wall Street accounting system. In other words, people who are not for the purpose of making money (early BTC players, positioned as competitors on Wall Street) have gained economic freedom. The purpose of the late participants is to make money. As a result, most of them lose money
- why do those who hope to make money lose money, while those who do not hope to make money make a lot of money instead
reference answer: the choice of competitors determines your position
others take Wall Street as their competitors and are at the top of the tower. Wall Street and the new financial promoters are at war, and pawns are injured<
- the competitor of cloud wallet is the Federal Reserve, and its bookkeeping logic is the same as that of the Federal Reserve
the bookkeeping logic of the Federal Reserve: Liabilities of others = assets of self, and all creditors' assets are paid by corresponding debtors
the accounting logic of cloud Wallet: Liabilities of public network = human assets = future services provided by public network = AIC. Similarly, all creditors' assets are paid by corresponding public network
blockchain and bitcoin, compared with the accounting system with the Federal Reserve as the core, are just like mountain bandits. People who get rights don't want to take on obligations. Each blockchain has its own way, and there are many factions in the mountain
cloud wallet is a regular army model, which relies on the efficiency advantages of accounting system and public network to expose the inefficiency and corruption of the US dollar system
cloud wallet has seven software engineers at present, and only 700 software engineers will be needed in the future to meet all the needs of global bookkeeping, trading and settlement. This efficiency is more than 3 million times higher than that of the Federal Reserve's bookkeeping system, which is maintained by hundreds of millions of financial practitioners. Cloud wallet is to give the right of choice to human beings. When human beings choose cloud wallet, the 20 trillion interest difference saved each year is the value created by everyone's leisure time. It is also the basic value of AIC
- in the cloud wallet system, you are a general and the public network is a pawn; In the blockchain system, you are a pawn, and the early players are generals.
- in the cloud wallet system, everyone can transform labor, proction capacity and services into super capital without legal money. In the blockchain system, there must be a large number of leeks.
- in the cloud wallet system, the world factory can be directly transformed into the wealth of the Chinese people, The world factory is not worth money at all
- the cloud wallet framework can hold the whole world, including the people behind the Federal Reserve and wall street; In the framework of blockchain, most people can only be reced to leeks
- cloud wallet framework, which takes time back to 2009, so that everyone can dig out the equivalent of bitcoin (gold stock) with their own leisure time and intelligence
- the general is up, the pawn is down! What is your choice?
In the traditional supply chain finance, financing difficulty, high financing cost and cumbersome financing process have always been one of the bottlenecks restricting small and medium-sized enterprises to become bigger and stronger. Banks rely on the ability of core enterprises to control goods and regulate sales. For the sake of risk control, banks are only willing to provide factoring services to upstream suppliers (limited to first tier suppliers) with direct accounts payable obligations of core enterprises, or provide prepayment or inventory financing to their downstream distributors (first tier suppliers). As a result, the demand of secondary and tertiary suppliers / distributors with huge financing demand can not be met, the business volume of supply chain finance is limited, and the small and medium-sized enterprises can not get timely financing, which will easily lead to proct quality problems and damage the whole supply chain system
to solve these problems, we can make use of the characteristics of decentralized, tamper proof and distributed ledger of blockchain technology to build a blockchain supply chain financial platform
The core enterprise issues a / R certificate to the distributor. After the distributor signs the receipt, it indicates that it has signed the purchase and sales contract and the core enterprise delivers the goods Because of the shortage of funds, distributors need to borrow money from finance3. After the financial institutions have approved, the amount of loans will be sent to the core enterprises
The distributor will repay the loan and interest after selling the goodsI hope I can help you:

abey blockchain technology is from Ciprian pungela & amp; Co., two doctors in the Department of artificial intelligence from the Department of computer science, School of mathematics and information, Western University of timishwara, Romania; Vorel negru's own research project. Constant lightweight blockchain technology and multi-layer programming and extended blockchain solution are adopted. The scale of abey's blockchain remains unchanged, with only 50 active blocks. Abey blockchain technology is suitable for the use of e-money in e-commerce system for mass transactions, and has multi-level, scalability and security, and can be programmed
according to the official white paper, abey is suitable for the blockchain solution in e-commerce system, which uses digital currency to carry out mass transactions and can carry out multi-layer programming and expansion
specific implementation method of abey blockchain Technology:
using a multi-level and programmable blockchain method to realize digital currency (for simplicity, we call it "DC"). This method can pave the way for the implementation of various e-commerce purposes, such as loan financing, completion of refundable transactions and non refundable transactions. In the first layer of the blockchain, we can realize the inherent digital currency design, which is commonly referred to as the base layer ("FL"). The various upper layers built on this foundation can be used to describe various additional functions related to various business driven application examples (which we will briefly introce below). All of the above levels are fully programmable, and can be easily adapted for various applications
although most of today's digital goods store transaction balance in the blockchain, abey's method is more similar to Pascal coin digital currency. This method uses what we call a "vault" encryption structure“ The "vault" structure can only save the balance of all accounts in the network, instead of a complete list of all completed transactions, and can be reconstructed in the evolution history of the blockchain. Since vault allows the deletion of useless content at any time, it can significantly rece the storage cost of blockchain. In contrast, at the time of writing this article, the storage space required to download bitcoin database is 70gb (the alarm rate is still growing, and it is expected to reach 300gb in 2019), so it is not feasible to use ultrabooks or notebooks with small storage space (such as 120GB or 256gb) to carry out mining operation. On the other hand, the size of the abey blockchain will remain unchanged, with only 50 blocks (at the time of writing, there are more than 525000 blocks in the bitcoin blockchain)
vault fully supports digital currency transfer between accounts. In addition, vault can assign an owner defined name to each account instead of using hashing algorithms like today's cryptocurrency - which makes the account easier to remember and makes the name public
one of the important functions that vault can help prevent the daily expenses of blockchain from being too high (especially those related to transaction history) is that vault can save such states and rece the size of blockchain itself by creating a secure of blockchain states. Because there is no transaction history and all accounts can save their direct balance, the blockchain information has the feature of partial erasure. All the blockchain states that can be stored can be regarded as landmarks of the blockchain
secure data sharing:
through the block chain structure design, for each transaction sent to the network, the block chain may contain encrypted metadata. The metadata can only be decrypted by the transaction recipient. For the transaction sent to the network, the sender's public key is included in the transaction, and the transaction receiver decrypts the metadata using the public key. Since the transaction receiver holds the private key for decryption, only the transaction receiver can implement the data decryption process. From the perspective of encryption method, although bitcoin is limited to elliptic curve cryptography, blockchain metadata can use any other encryption mechanism to complete the encryption process. This not only provides complete flexibility in security selection, but also does not have any adverse impact on the structure or function of the blockchain
scalability:
since the abey blockchain supports the creation of historical landmarks by design, it is very easy for the network itself to achieve high scalability from the point of view that the blockchain will always need to store (related to the latest existing SLS). This method completely eliminates the need to store transaction history to calculate the balance of all accounts, and can directly store all account balances, so as to ensure that the specific balance information provided by all nodes in the network meets the requirements of Byzantine consistency
proof of security and workload:
it is impossible to have two-way payment operation in abey's method (in the specified appropriate scenario, the vast majority of today's mainstream cryptocurrencies may theoretically have two-way payment operation). Each transaction means that the balance of the corresponding account is updated in a relatively simple way, and there is no special way to restore the transaction from the network pending transaction team. For the abey blockchain, since all technical / functional layers are built on vault, vault is the infrastructure of our blockchain, so vault is very important for mining operations. Our proposed blockchain model is composed of a series of blocks, each of which is generated by the nodes in the network who are willing to mine. All nodes in the network can update the account balance independently according to the transaction (part of the block), and are independent of other nodes. The mining operation will affect the first functional layer. In addition to updating the balance, each node can also update other matters that may belong to the upper functional layer in the composition of the blockchain structure. Once an update occurs, a new mining incentive block will be created. The mining reward block contains a number of new reward accounts that have been assigned to miners. The miner is the winner of the above reward according to the workload Certificate (currently there are 50 reward accounts). The way to reward is to distribute the public key of all such accounts to the reward recipient
blockchain technology layer:
abey's digital currency model contains a multi-layer structure, in which the first layer represents the realization of the digital currency itself (see Figure 7 for graphic explanation). The corresponding levels include:
tier 1 → digital currency (cryptocurrency): currency transfer, mining
tier 2 → refundable transaction and non refundable transaction: allowing the use of digital justice system to complete refundable transaction
Tier 3 → related parties and commission: allowing the automatic distribution of Commission to related parties
Tier 4 → contacting currency: by lending currency, Income based on interest
layer 5 → programmable: reserved for future realization of Turing complete programming model, so as to process blockchain data in a customized way (such as smart contract)
layer 6 → custom protocol: reserved for future use
transaction type:
abey mode allows different levels in blockchain through design, Complete a variety of transaction types. The transaction types in the second layer are as follows:
1 → fund transfer: fund transfer between accounts (1-to-1 transfer)
2 → refundable fund transfer: refundable transaction between accounts. Use escrow balance instead of regular account balance
3 → key change: change the key that can be used to process the account
4 → restore the account: recover funds from the lost and invalid account
5 → set account name: define the name of the account held by the founder
6 → sales preparation: mark the account for sale
7 → move out of the sales queue: remove the account sales mark, And the account is marked as non saleable
refundable transaction and mediator:
for the vast majority of cases, non refundable transaction is equivalent to all "pay to pay" transactions in blockchain based digital currency mode. But abey has introced the concept of refundable transactions into its digital currency model. In abey mode, the transaction marked with small flag belongs to refundable or non refundable transaction. In addition, in abey's blockchain network, each account contains two types of balance: regular and unchangeable balance (used to mark the amount that the account has received and can be paid immediately, but cannot be recovered after the payment) and escrow balance (including the transaction list marked as refundable transaction and the minutes of each transaction)
8 → payment dispute: for the corresponding transaction that has been marked as a refundable transaction, the payment dispute can be initiated only by the payer
9 → refund request: for the corresponding transaction previously marked as a refundable transaction, a refund request can be initiated, but only by the payer
10 → cancel escrow: cancel the escrow funds and return the funds to the payer immediately. It can only be initiated by the payee
11 → release trusteeship: release the trusteeship fund and add the amount to the balance of the payee's account immediately. It can only be initiated by the payer
related parties and commissions:
one of the important deficiencies in today's blockchain driven financial technology is the lack of the ability to provide rewards to related parties who sell specific procts or services. The third layer of abey blockchain can solve this problem< Lending digital currency:
lending digital currency is not only a simple and quick way to allow people to borrow legal tender, but also to ensure the security of encrypted assets. Given that today's valuable digital currencies are also used for transactions, the reason why lending digital currencies is feasible is not only that it allows borrowers to mortgage any type of cryptocurrency they save, but also that it is attractive because it is a way to retain their digital assets in a completely safe or very low-risk way. In addition, abey's model also provides built-in protection through the customer vault lending gateway (VLG), and enables the VLG to act as a buffer between the lender and the borrower
12 → borrowed funds: the borrower initiates transactions in the network, announces the intention of borrowing funds, and specifies the VLG account of the borrowed funds. The transaction is similar to depositing the balance of the regular / escrow account in the selected VLG account
13 → return of collateral: the transaction is initiated by the VLG itself. VLG will return the collateral to the borrower in accordance with the risk management policy
14 → loan repayment: the transaction is initiated by the borrower. If VLG accepts repayment of the loan in digital currency, the borrower may choose to repay the loan in digital currency. Under this condition, the digital monetary fund will be converted into VLG regular account balance<
programmable blockchain:
with its associated metadata payload, the layer of blockchain can be retained to allow the further creation of intelligent contracts between peers in the network by executing the grammar based "complete Turing basic programming language" according to the original blockchain data processing mode. For each payload, encryption or public visibility processing can be implemented, and can be performed in a dedicated virtual environment (similar to a virtual machine). This method can effectively protect data security and avoid the impact of data destruction and security vulnerabilities. The main advantage of this method is that this layer can create and enforce digital contracts without any blockchain specific programming. For Ben
1. Blockchain technology can realize the automatic transaction settlement of the exchange, bypass the third party, improve the transaction speed, rece costs, rece operational risks and human errors
2. At present, blockchain technology is mainly used for post transaction clearing services, as well as equity trading management in the OTC market, rather than the mainstream exchange market. The reason is that blockchain technology needs a lot of storage space and a long confirmation time, coupled with the limitation of transaction speed, it is not suitable for centralized floor trading
3. Because of its confidentiality and unchangeable characteristics, blockchain is suitable for securities registration and can rece the registration time
4. Blockchain technology is a double-edged sword for the exchange. On the one hand, it helps the exchange rece the operating costs and risks, and on the other hand, it also reces the income of the exchange in clearing (the decrease of settlement fees and the shortening of settlement cycle will rece the interest income of the custody bank and settlement company). Therefore, for the exchange, it is necessary to develop new data services to make up for the revenue after using the blockchain
of course, blockchain will also have some positive effects on traditional instries. Blockchain has had a positive impact on crowdfunding, banking and tea collection. Puyin group launched the tea based digital currency Puyin.
I have a similar one. It should be a commemorative stamp for postal savings issued in the year of the Dragon (2000). As shown in the figure:
