Description
Technical Field
The present disclosure relates to the field of blockchain transaction data transmission technologies, and in particular, to a method and an apparatus for transmitting evidence of blockchain transaction data.
Background
Blockchains are a kind of decentralized distributed ledgers that are updated by nodes in the peer-to-peer network. The update of the ledger is mainly divided into two functions: blockchain data broadcasting and block expansion. However, currently, there are only two types of incentives in most blockchain protocols: block rewards and transaction fees, which motivate only block expansion. For transactions and broadcasting of block data, current blockchain networks rely primarily on nodes in the network voluntarily transmitting received transactions to neighboring nodes. Such a transmission mechanism does not have any incentive to the nodes broadcasting the transaction or the blockchain information, resulting in the nodes lacking motivation to actively relay blockchain data and the power to actively boost the bandwidth capability, ultimately resulting in a larger blockchain data transmission delay.
Aiming at the quantization problem of block chain data transmission work, a signature chain mode is mainly used at present to prove the transmission behavior. In signature chain based transmission certification schemes, it is necessary to attach a public key for each relay to receive the transmission stimulus and a signature for signing the message when propagating the message. The relay node continuously continues to sign on the signature of the previous version and the message, and continuously propagates the version after updating the signature to other nodes, so that a signature chain capable of representing the propagation path can be finally generated. Any modification to the signed data packet will invalidate it unless it is re-signed. Thus, anyone can verify the path in the data packet and a malicious party cannot tamper with or forge the data packet without the private key used by all the signatures on the signature chain.
Transaction or block information may have multiple paths in the network propagation, and each transaction or block may have a different version of the signature chain for many paths. When a block is output, only signature chains on one propagation path are saved on the chains, and signature chains on other paths are discarded. The final uplink signature chain can provide transmission work evidence for all relay nodes participating in transmission on the path, and the relay nodes can obtain propagation excitation according to a certain transmission excitation mechanism. Because the propagation of transaction or block information ultimately cannot guarantee uplink and obtain rewards, the relay node can only propagate different transaction or block information more if it wants to obtain more incentives. Considering the characteristics of the P2P network and the blockchain data transmission, if the relay node propagates early in the transaction or blockchain initiation, its signature will be in the earlier part of the signature chain. This means that the signature of the node can appear in more propagation chains, increasing the probability that the node appears on the final outgoing transport chain. The signature chain-based transmission proving mode encourages relay nodes to forward transactions or blocks as early as possible, and forwards the transactions or blocks to more nodes so as to acquire more transmission incentives.
The NKN system uses a signature chain based relay attestation method. And the relay node sequentially signs the data packets when relaying the data packets to form a signature chain of the participant according to the participation time sequence. Each signature in the signature chain contains the NKN address and public key of the relay node, the NKN address of the next relay node, which continues to sign on the basis of the previous version signature. The signature chain generates signatures with the number corresponding to the number of nodes after the signatures of the relay nodes on all propagation paths, and generates great storage overhead. Ersoy et al propose a mechanism for reducing redundant communication costs using intelligent network routing. The additional storage requirement is only the public key of the node on the propagation path and the signature of the client, so that the storage overhead of the signature chain is effectively reduced. But the method relies on shorter network route and has no popularization significance.
The signature chain-based transmission proving method is relatively high in space overhead. The UTXO model proposed by Wang et al to change one transaction to multiple relay transactions can result in even more transactions, making the overhead of the transmission evidence on the chain greater. The signature chain-based transmission proving method can finish the function of proving the workload of the relay node and solve the problem of information competition in transmission excitation, but the method brings larger storage and network burden to the blockchain network and is not beneficial to the efficiency of the blockchain network.

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present application and are not to be construed as limiting the present application.
The following describes a block chain transaction data transmission evidence method and device according to an embodiment of the present application with reference to the accompanying drawings. Aiming at the problem that the transaction data transmission work in the blockchain network is difficult to prove and quantify, which is mentioned in the background center, the application provides a blockchain transaction data transmission evidence method, in which transaction data is subjected to aggregate signature to replace a signature chain so as to prove the workload of a relay node participating in data transmission, and the method has the advantages of saving transmission bandwidth and on-chain space and being universal for various blockchain networks. Therefore, the problems that an incentive mechanism for transaction data transmission is lacking in the current blockchain network, the quick propagation of transaction information in the blockchain network is not facilitated, and the throughput and the safety of a blockchain system are indirectly influenced are solved.
Specifically, fig. 1 is a flowchart of a blockchain transaction data transmission evidence method according to an embodiment of the present application.
As shown in fig. 1, the blockchain transaction data transmission evidence method includes the following steps:
in step S101, signature authentication is performed on a public-private key pair used by the transaction initiator for aggregating signatures, and initial aggregated signatures are performed on the blockchain transaction data to be transmitted by using the authenticated public-private key.
To achieve the incentive for transaction data transmission, work proof is required for the transaction data transmission work. The embodiment of the application uses the aggregated signature to replace the signature chain scheme which is currently used in the mainstream, the signature of the relay node is aggregated into one signature to reduce the expenditure of transmission evidence, and the aggregated signature ensures that the follow-up relay cannot tamper with the previous transmission evidence.
In the transmission proving method based on the aggregate signature, a transaction initiator is required to initiate an initial aggregate signature, so as to ensure that a subsequent relay node cannot generate a new aggregate signature privately. However, the signature algorithm in the current mainstream blockchain transaction structure is typically elliptic curve algorithm and does not support the signature aggregation function, so the address in the transaction cannot be directly used as the identity of the initial aggregated signature. Thus, embodiments of the present application design an authorization signature structure that uses the form of a signature to authorize an initial aggregate signature with a private key corresponding to a transaction initiator.
The transmission proving method based on the aggregate signature mainly carries out signature authentication on public and private key pairs used by the aggregate signature through a transaction initiator, uses the authenticated private key to carry out initial aggregate signature on the transaction, then transmits the signed transaction information to the next relay node to continue the aggregate signature, and finally forms the transaction information containing the aggregate signature of the relay node on the complete transmission path. The aggregate signature may provide proof of transmission for the nodes participating in the relay, with verifiability and non-tamper.
In the embodiments of the present application, it is mainly divided into two parts: an authorization signature structure and a transmission evidence structure. First, the authorization signature structure will be explained.
Optionally, in one embodiment of the present application, signature authentication is performed by the transaction initiator on a public-private key pair used by the aggregated signature, and initial aggregated signature is performed on the blockchain transaction data to be transmitted by using the authenticated public-private key, including: randomly generating a public-private key pair for the transaction initiator to aggregate the signature; signing the public key in the public-private key pair and the blockchain transaction data to be transmitted by utilizing the private key of the address corresponding to the blockchain transaction data to be transmitted to obtain an authorization structure; and signing the blockchain transaction data to be transmitted by utilizing the private key in the public-private key pair to obtain an initial aggregate signature.
To use aggregate signatures in different block chain systems, embodiments of the present application add an authorization signature structure to the proof of transmission for enabling the transition of different signature systems to an aggregate signature system. In the authorization structure, sign represents the signature algorithm used by the original transaction, and AggSign represents the aggregate signature algorithm. To complete the authorization operation, transaction initiator A first randomly generates a public-private key pair of an aggregate signatureThen the private key SK of the corresponding address of the transaction is used again A For the public key generated above +.>Signing with transaction IDTxID to obtain +.>Finally, the private key of the aggregate signature is used again>Signing the transaction IDTxID, generating a first aggregate signature +.> As shown in fig. 2. The transaction initiator may use the signature algorithm of any original transaction to generate an aggregate signature through an authorization operation. After the authorization operation, the public and private key pair of the authorized aggregate signature has the same authority as the transaction initiator, a malicious party cannot tamper the original transaction information and the signature, and the transaction information after the initial signature is completed can be transmitted to the next relay node for continuous transmission.
In step S102, the to-be-transmitted blockchain transaction data including the initial aggregate signature is received by at least one relay node, and the to-be-transmitted blockchain transaction data is broadcast after adding its own aggregate signature to the initial aggregate signature of the to-be-transmitted blockchain transaction data.
The method solves the problem that the transaction initiator generates the aggregate signature under different signature systems, and the subsequent relay node can continuously add the aggregate signature on the basis of the first aggregate signature to generate complete transaction information transmission evidence. After the transaction initiator completes the initial aggregate signature, broadcasting to the neighbor nodes, and the neighbor nodes continue broadcasting after adding the self aggregate signature to the transaction for obtaining transmission stimulus.
The scheme based on the aggregate signature adopted by the embodiment of the application is different from a signature chain scheme, and the transmission public key needs to be negotiated with the relay node in the signature chain scheme.
Optionally, in one embodiment of the present application, adding an aggregate signature of the blockchain transaction data to be transmitted, broadcasting the blockchain transaction data to be transmitted includes: randomly generating a transmission public-private key pair of at least one relay node; signing the blockchain transaction data to be transmitted by utilizing a private key in the public-private key pair, and aggregating the signature result and the existing aggregation signature to generate an intermediate aggregation signature; and broadcasting the public key, the intermediate aggregate signature and the authorization structure of the transmission public-private key pair and the blockchain transaction data to be transmitted to other relay nodes.
Optionally, in one embodiment of the present application, before randomly generating the transmission public-private key pair of the at least one relay node, the method further includes: verifying validity of the block chain transaction data to be transmitted; and when the blockchain transaction data to be transmitted is valid, verifying the validity of the authorization structure and the aggregate signature in the blockchain transaction data to be transmitted.
Sign represents the signature algorithm employed by the original transaction, and AggSign represents the signature algorithm used to aggregate signatures. The transmission evidence structure is shown in fig. 3 and consists of an authorization structure, a public key list and an aggregate signature. The construction flow is as follows:
1) First, the transaction initiator A generates an authorization structure according to the procedure described above, which includes a first aggregate signatureForwarding the structure to all adjacent relay nodes along with the transaction Tx;
2) Then the first repeater R 1 After verifying the validity of the transaction, the validity of the authorization structure and the aggregate signature are again verified, and after verification, R 1 Transmission public-private key pair corresponding to random generation aggregation signature algorithm
3) Relay R 1 Then using the generated private keySigning the transaction IDTxID to generate an aggregate signatureThe signature is then associated with->Aggregation is performed to generate an aggregate signature->Finally, public key->Aggregate signature->And an authorization structure that forwards to all neighbor nodes along with transaction Tx;
4) Subsequent relay R i Repeating the steps 2) and 3) until the transaction is transmitted to the whole network or the uplink is completed.
In step S103, the to-be-transmitted blockchain transaction data of at least one relay node is received, and after adding its own aggregate signature in the aggregate signature of the to-be-transmitted blockchain transaction data, the to-be-transmitted blockchain transaction data is broadcasted until the to-be-transmitted blockchain transaction data transmission is completed.
Through the steps, after the transaction data of the blockchain to be transmitted is propagated for a plurality of times, a plurality of different propagation chains are generated, wherein transaction information is attached to aggregated signatures generated by different propagation paths. Finally, only transaction information and aggregate signatures on one path can be chained, and transaction information on other paths can be discarded.
Optionally, in one embodiment of the present application, after the transmission of the blockchain transaction data to be transmitted is completed, the method further includes: and verifying the aggregate signature of the transmitted block chain transaction data to be transmitted by using the public key of the relay node, determining whether the relay node participates in the transmission process of the block chain transaction data to be transmitted, and if so, exciting the relay node participating in the transmission process according to a preset excitation rewarding rule.
After the transaction is uplink, the aggregate signature in the transaction information may provide a proof of transmission for the relay node. The blockchain network provides incentives for nodes participating in the relay according to different incentives mechanisms.
It should be noted that, the aggregate signature in the present application may be replaced by other signature methods that can achieve the same functions and costs as the aggregate signature.
