Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A Block Chain (Block Chain) technology is a bottom layer technology of encryption currency of Bitcoin, Ether Fang and the like, and a technical framework formed by technologies based on a P2P network, cryptography, a consensus mechanism and the like is mentioned in a Bitcoin paper Bitcoin: A Peer-To-Peer Electronic case System.
Blockchains are widely used in bitcoin, etherhouse, ZCash, etc. cryptocurrencies. The blockchain does not rely on trusted authority maintenance of a third party, but rather records and stores data in a distributed manner in the P2P network. The block chain is a block and chain structure, the nodes pack transaction data within a certain time to generate a block according to the time sequence, the nodes attach the block to the local block chain database of the nodes, and simultaneously broadcast the block to the adjacent P2P nodes.
As shown in fig. 1, a block is composed of a block header and a block body. The HASH, timestamp, difficulty value, random value, and root of Merkle (trusted tree) of the last tile are stored in the tile header. The block body stores main transaction data, each transaction is generated into a HASH according to the generation rule of the merkle tree, and every two HASAs are used as HASH indexes to finally form a merkle root which is stored at the head of the block body. The chain structure of the block chain now holds the HASH of the last block at the block head.
The operation mechanism of the block chain is that the database of the block chain is distributed in the whole network, all nodes maintain the same block chain account book together, and data of a single node is tampered and is not enough to influence the whole network. Each node can forward the received legal transaction data, and the ledger data of the transaction can be checked by all nodes through a consensus mechanism. The legitimacy and integrity of the transaction data can also be guaranteed when the institution lacking third party credit undertakes insurance.
Bottom layer technology of block chains:
1) asymmetric encryption:
asymmetric encryption is the core encryption technology of the blockchain technology, and in the blockchain, the requirements of security and authentication of the blockchain system are met. Common asymmetric encryption algorithms include RSA, ECC (elliptic encryption), D-H, etc., and the asymmetric algorithms generate a public key and a private key in the encryption and decryption processes, the private key can be derived from the elliptic encryption, and the public key cannot be derived from the private key in the reverse way. The public key can be published to the whole network, so that the data can be signed by the private key and needs to be verified by the corresponding public key; or encrypted with the public key and decrypted with the private key.
In cryptocurrency, such as bitcoin, the initiator of the transaction signs the transaction with a private key, while other nodes can verify with their public keys. The initiator of the information signs the information by using the public key of the receiver, and the receiver of the information decrypts the data by using the private key of the receiver to obtain the decrypted original data.
2) HASH function:
the blockchain is also called a HASH chain because the blockchain generally does not store the original record of the transaction, but stores the HASH value of the blockchain, and the original data of the transaction is subjected to HASH operation to obtain a fixed-length hexadecimal HASH value and recorded into the blockchain. The unidirectionality of the HASH function ensures that original data cannot be reversely deduced through results, and different data cannot correspond to the same HASH value, so that a block chain system cannot generate recording conflict in the operation process.
3) Point-to-point network:
a Peer-To-Peer (P2P) network is a network structure of a blockchain system, and a P2P network is a flat network structure, and connects nodes in different places in the world, so that a central server system does not exist. In the block chain system, nodes can independently bear the routing of the network, propagate transaction, block data and verify the validity of the data.
4) A consensus mechanism:
the blockchain system is a distributed system, and the consensus mechanism solves the problem of rapidly and accurately achieving consensus in the distributed system. The currently commonly used formula algorithms include Proof Of Workload (POW), Proof Of rights and interests (POS), and bazaltine fault tolerance (PBFT). The consensus mechanism is mainly established under the condition that the consensus mechanism does not depend on centralized nodes to verify the legality of the transaction and exclude illegal transactions, so that the uniqueness of the longest chain of the block chain is facilitated.
5) Intelligent contract:
the intelligent contract is a set of logic established on the basis of the bottom layer block chain, the bottom layer data is realized by the bottom layer of the block chain, and the intelligent contract realizes more flexible programming by utilizing a set of code algorithm to realize more complex transaction logic. In a blockchain of an ether house or the like, intelligent contracts are stored in a blocky block, and the current state change of the intelligent contracts is triggered by a transaction. Each time the intelligent contract is called, a fixed format transaction needs to be sent, if the transaction is legal, the transaction is added into the merkle tree, and the intelligent contract is changed into the next state.
Based on the above theory, an embodiment of the present invention provides a method for sharing educational resources based on a block chain as shown in fig. 2, including:
s101, receiving right confirming information uploaded by a copyright owner, carrying out right confirming verification according to the right confirming information, and if the verification is passed, generating an intelligent contract according to digital education works in the right confirming information;
s102, displaying the digital educational works according to a preset display mode;
s103, when purchase information containing partial ownership of the digital educational works is received, a trading contract is generated according to the purchase request, and the trading contract is sent to the copyright owner and the copyright purchaser;
and S104, if the trading contract is judged to be effective, changing the ownership of the digital education works according to the purchase information, and storing the change information into a block chain.
In step S101, the digital educational works include educational videos, educational words, educational pictures, educational courseware, etc., when the copyright owner uploads his digital educational works to the block chain, it is necessary to submit the copyright certification information, digital signatures, etc. together with the digital educational works, and after the copyright certification information passes the copyright certification verification, an intelligent contract of the digital educational works is generated.
Because the unique advantages of the blockchain are that data cannot be tampered, timestamp authentication is performed, and a reliable and reliable database is maintained by the distributed consensus nodes, the student academic data is stored in the blockchain according to the advantages, and the public and fair of the student academic data are guaranteed. The personal information of the student is contained in the database of the blockchain, and only the authorized data can be viewed, or the specific person is authorized to view the corresponding data. Through this embodiment, the student can provide own data for the usefulness of authentication high-efficiently, protects own privacy when guaranteeing the data justice moreover.
The intelligent contract of the EtherFang block chain provides a script language with complete graphic, and the management work which needs the participation of people can be automatically executed by the block chain, thereby improving the efficiency of the educational resource sharing system. The operations of uploading, chaining, sharing and the like of the resources can be automatically carried out by the intelligent contract, and meanwhile, the intelligent contract can also realize the functions of storing personal information and protecting privacy.
On the basis of the blockchain technology and the intelligent contracts, the embodiment of the invention constructs an application framework of an educational resource sharing system combining blockchain and education, as shown in figure 3. The application framework adopts the block chain technology as the storage of user personal data, the construction and the transaction of a P2P network and a consensus node. By adding an intelligent contract layer, the block chain can realize the storage and evidence saving of the education digital resources, and also has the functions of the decentralized investment, the distributed communication and the higher-level transaction of the digital education works. In the form of decentralized APP at the application level, all operations and transactions on smart contracts will be recorded to the underlying database of the blockchain.
