Description

Background
With the rapid development of information technology, block chaining technology has emerged. A block chain (also called a blockchain, english: block chain or block chain) is a concatenated record (also called a block, or block) that is cryptographically concatenated and protects content. Each block contains a cryptographic hash of the previous block, a corresponding time stamp, and the original data, such a design makes the block content nearly tamper-resistant. The distributed record chain connected in series by the block chain can effectively record data by each party and permanently check the data. The characteristics enable the block chain technology to be very suitable for important fields such as finance, law enforcement (evidence preservation), information security and the like, product quality tracing and the like, and have strong development potential.

Those skilled in the art will understand that: the various functions and/or operations within these block diagrams, flowcharts or examples can be implemented, individually and collectively, by a wide variety of hardware, software, firmware, or any combination of hardware, software and firmware.
The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
The noun explains:
example one
As shown in fig. 1, the present embodiment provides a block chain experiment system, which includes at least one network unit and N experiment platforms (experiment platform 1 to experiment platform N). The network unit is used for network connection between the experiment platforms. The experiment platform consists of an experiment machine, credit input equipment and credit output equipment, and can realize the complete function of the block chain nodes.
Wherein, the experiment machine includes:
and the processing unit is used for generating the creation block and processing the synchronization, distribution and verification work between the block and the block chain experiment system. The processing unit is connected with the network unit. The processing unit can be a general-purpose electronic computer, an embedded electronic computer, or the like, and runs a corresponding operating system and application software, so that basic functions of the block chain, such as generation and creation of blocks and data processing, synchronization, distribution, and verification of the blocks and the block chain, and the like, can be realized.
And the storage unit is connected with the processing unit and is used for storing the data of the block chain. The storage unit can be a random access memory, a hard disk, a solid-state disk and the like.
And the algorithm acceleration unit is connected with the processing unit and is used for accelerating a data processing algorithm and an encryption algorithm, generally hardware acceleration.
The algorithm acceleration unit adopts one or more of the following data parallel operation processors: digital Signal Processors (DSPs), programmable logic devices (e.g., FPGAs), and image processors (GPUs), among others. The data operation of the algorithm accelerating unit is highly parallel, and the processing speed far exceeds that of the processing unit.
The data processing algorithms include one or more of the following algorithms: an image processing algorithm, a sound processing algorithm, a physical quantity processing algorithm, and the like; the image processing algorithm, the sound processing algorithm, and the physical quantity processing algorithm are correspondingly applied to process the image signal, the sound signal, and the physical quantity signal.
The encryption algorithm comprises one or more of the following algorithms: digest algorithms, symmetric encryption algorithms, asymmetric encryption algorithms, and signature algorithms.
The abstract algorithm is an algorithm for generating pseudo-random input with fixed length by kneading input with arbitrary length. The length of the calculated message digest is always fixed regardless of how long the incoming message is. And the message digest appears to be "random".
The symmetric encryption algorithm is that in the symmetric encryption algorithm, a data sender processes a plaintext (original data) and an encryption key together through a special encryption algorithm, and then the plaintext and the encryption key are changed into a complex encryption ciphertext to be sent out. After the receiver receives the ciphertext, if the receiver wants to decode the original text, the receiver needs to decrypt the ciphertext by using the key used for encryption and the inverse algorithm of the same algorithm so as to recover the ciphertext into readable plaintext. In the symmetric encryption algorithm, only one key is used, and both the sender and the receiver use the key to encrypt and decrypt data, so that the encryption key must be known by a secret party in advance.
Asymmetric encryption algorithms require two keys: public keys (public keys for short) and private keys (private keys for short). The public key and the private key are a pair, and if data is encrypted by the public key, the data can be decrypted only by the corresponding private key. Encryption and decryption use two different keys. The basic process of realizing confidential information exchange by the asymmetric encryption algorithm is as follows: the first party generates a pair of secret keys and discloses the public keys, and other roles (the second party) needing to send information to the first party encrypt the confidential information by using the secret keys (the public keys of the first party) and then send the encrypted confidential information to the first party; the first party decrypts the encrypted information by using the private key of the first party. The method is characterized in that when the party A wants to reply to the party B, the opposite is true, the public key of the party B is used for encrypting data, and similarly, the party B uses the private key of the party B for decrypting.
The signature algorithm is a digital string which can be generated only by a sender of information and cannot be forged by others, and the digital string is also a valid proof of the authenticity of the information sent by the sender of the information. The signature algorithm is an alphanumeric string that is processed through a one-way function to authenticate the source of the message and verify whether the message has changed during transmission.
In this embodiment, the block chain experiment system further includes:
the output end of the credit input device is connected with the input end of the processing unit, and the credit input device is used for acquiring external information, processing the external information, signing the external information and outputting the external information to the processing unit; the credit input equipment comprises a sensor with an electronic signature function, and/or a keyboard and/or a camera, and/or a bar code/two-dimensional code scanner, and/or a node of the Internet of things. The user can input information through the credit input equipment to realize interaction with the block chain experiment system.
The input end of the credit granting output device is connected with the output end of the processing unit, and the credit granting output device is used for receiving the instruction from the processing unit and executing corresponding output action;
the credit output device comprises a display with an electronic signature function and/or a loudspeaker and/or a printer and/or a mechanical execution structure; correspondingly, the output action comprises a display and/or a sound and/or a printing and/or a mechanical movement.
