Who is the project party of ABS encryption blockchain
selfsell launched j-rowjames Rodr í Guez's token, J Luo's cryptocurrency is called jr10 token, Jr is his initials, 10 is his jersey number, this cryptocurrency will be on sale on June 12 this year
selfsell token is SSC, now it can be traded in okex and lbank
more can be online, thank you
asymmetric encryption algorithm is a function that converts the original plaintext file or data into a series of unreadable ciphertext codes by using an encryption key. The encryption process is irreversible. Only holding the corresponding decryption key can the encrypted information be decrypted into readable plaintext. Encryption enables private data to be transmitted through the public network under the condition of low risk, and protects the data from being stolen and read by the third party
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
· users who are optimistic about the future of digital assets and hope to hold them for a long time, but have short-term and medium-term liquidity needs
two parties: dagt Foundation (non-profit), which is responsible for the R & D, operation and promotion of dagt projects
· based on blockchain technology, Provide digital asset loan credit service for credit users
tripartite: refers to institutions that comply with relevant national laws and have loan qualification, such as banks, online loan companies, small loan companies, etc.
· dagt system will realize system docking with third-party loan institutions
1.1. Introction
practitioners in the computer instry should be very familiar with the word hash. Hash can realize the mapping of data from one dimension to another, and hash function is usually used to realize this mapping. Generally, y = hash (x) is used in the instry. The hash function can calculate a hash value y by calculating X
hash function characteristics in blockchain:
function parameters are string type
fixed size output
is computationally efficient
collision free means that the conflict probability is small: X= y => hash(x) != Hash (y)
hide the original information: for example, the verification of transactions between nodes in the blockchain only needs to verify the information entropy of the transaction, and does not need to compare the original information. The nodes do not need to transmit the original data of the transaction, only the hash of the transaction, Common algorithms include Sha series and MD5
1.2. Hash is widely used in blockchain. One of them is called hash pointer
hash pointer, which means that the value of the variable is calculated from the actual data and points to the actual data location, That is, it can not only represent the actual data content, but also the storage location of the actual data. The figure below shows the schematic diagram of hash pointer

the details of these two digital assets are as follows
bitcoin (bitcoin: bitcoin) was originally a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
the full name of NMC is "new media chain", the Chinese name is media chain, and the former domain name currency (also referred to as NMC) is two completely different currencies. NMC is the circulating currency of three decentralized application platforms: coin call [blockchain information community portal], coin search [blockchain network query tool], ncoin [digital currency exchange]. However, the prices of these two kinds of digital currencies will fluctuate with the market, which can not guarantee a development prospect. If the current price is concerned, bitcoin will be a bit higher.
there is no legal person in blockchain, and blockchain is a technology. Now many people are focusing on blockchain technology. Blockchain technology is the underlying protocol of bitcoin, Ruitai coin, Weimeng coin and other digital currencies.
