The embodiment further performs a step of uplink transmission for the user, which includes the following steps: initiating an uplink request; identifying a warrant type of the uplink request; storing the uplink request into a message pool according to the certificate storage type of the uplink request; according to the storage information in the message pool, block packing operation is carried out through the accounting node; recording the packed blocks on the accounting node; and other nodes in the block chain synchronously record the packed blocks through adjacent nodes.
And S3, accessing the block chain in a distributed manner through different nodes, and monitoring and tracking the hoisting equipment.
Further as a preferred embodiment, the method further includes a step of performing duplicate checking on the monitoring information in the block chain, where the step includes the following steps:
acquiring an information fingerprint of each piece of monitoring information; the information fingerprint is obtained by calculating monitoring information through an encryption algorithm.

In another embodiment, the method further comprises a step of performing duplicate checking on the monitoring information in the block chain, wherein the step comprises the following steps:
acquiring an information fingerprint of each piece of monitoring information;
broadcasting the information fingerprint to a block chain before uplink of the monitoring information;
and all nodes carry out information duplication checking locally through the information fingerprints, and link the monitoring information if the information fingerprints are determined not to be stored on any node.
As shown in fig. 3, in one embodiment, the present application further includes a rotation step of endorsement nodes and sort nodes, which includes the following steps:
determining an endorsement node, a sequencing node and a common node which are initially set;
after processing a plurality of rounds of transactions, each node competitively selects endorsement node identities and sequencing node identities;
voting by other nodes to determine a election result;
and determining endorsement nodes and sequencing nodes and operating a block chain according to the election result.
Specifically, in this embodiment, when building a block chain network, the identity of a node is determined first, and the node is set as an endorsement node, a sorting node, and a common node. And after the initial identities of all the nodes are determined, operating the block chain according to the roles of all the nodes. The endorsement node is a transaction endorsement sent out for the node, the sequencing node is used for sequencing the transactions in the block chain network, and the common node can only initiate the transaction and can not process the transaction. After the block chain network operates N rounds of transactions according to the initially set node mechanism, a rotation mechanism is started to prevent cheating. When the election countdown is started, nodes freely conduct election to become endorsement nodes and sequencing nodes, and whether election of the nodes is agreed or not is voted by the rest nodes. And after the election time is over, operating the block chain according to the identity of the new node. For example, a node sends a message (representing election endorsement node, 0: election endorsement node, 1: election sequencing node) with type 0, other nodes on the network perform optimization according to terdermint consensus algorithm (termindermint belongs to Byzantine fault-tolerant algorithm, and aims at the traditional PBFT algorithm, the consensus can be achieved only by two rounds of voting, the present termindermint algorithm is mainly applied to a block chain system), the other endorsement nodes assist in counting voting, and if the approval number of the node is more than or equal to 2/3 of the total voting result, the node successfully performs election and is informed to become the endorsement node. The endorsement nodes successfully elected operate by using the identities of the endorsement nodes.
In one embodiment, the data structure of the message is:
{
type:0,
ip:'x.x.x.x',
timestamp:xxx,
identity:”
}
in another embodiment, as shown in fig. 4, the rotation step of the endorsement node and the sorting node of the present application comprises the following steps:
determining an endorsement node, a sequencing node and a common node which are initially set;
after processing a plurality of rounds of transactions, determining endorsement nodes and sequencing nodes of a new round through a verifiable random function VRF;
and running the block chain according to the newly determined endorsement node and the sequencing node.
Specifically, in this embodiment, a verifiable random function VRF is employed to determine a rotation mechanism of endorsement nodes and sort nodes. When a block chain network is built, the identity of a node is determined, and the node is set as an endorsement node, a sequencing node and a common node. And after the initial identities of all the nodes are determined, operating the block chain according to the roles of all the nodes. The endorsement node is a transaction endorsement sent out for the node, the sequencing node is used for sequencing the transactions in the block chain network, and the common node can only initiate the transaction and can not process the transaction. After the block chain network operates N rounds of transactions according to an initially set node mechanism, in order to prevent cheating, VRF is used for rotating node identities.
VRF is a way to let each node draw itself, and if it is hit, one can easily verify that the result is indeed what you generated. The specific process may be as follows: assuming that it is round 10 (round 10), nodes may take their turn to draw lots, and generate a random number (0-100) by taking the private key of the node itself + a random number known by the whole network (for example, round 10 of the round) as input; setting a condition: the 100 nodes draw lots in turn, and the round packer is the round that who draws the random number first is larger than 10. Suppose node 5 has drawn 11, but only node 5 knows that others do not, so that he needs to broadcast a zero knowledge proof at the same time as it broadcasts the random. And zero knowledge proves that the whole network can be verified only by the public key of No. 5, and the node selected by the round of No. 5 is accepted.
And automatically determining the new node identity through a VRF algorithm, and operating the block chain according to the new identity after determining the new node identity.
In some embodiments, the method further comprises the step of accident tracing, which comprises the steps of:
judging whether a special operation certificate and a face recognition attendance record issued by a user exist on the block chain, if so, executing the next step; if only a special operation certificate is available and no face identification attendance record is available, determining to enter the next step according to actual conditions after online pursuit; if no special operation certificate exists, only the face recognition attendance record or both the face recognition attendance record and the face recognition attendance record do not exist, and the user is responsible for the accident;
judging whether equipment can safely use the certificate or not on the block chain, and if so, executing the next step; otherwise, confirming that the detection unit undertakes accident responsibility;
judging whether the block chain is qualified for installation, if so, executing the next step; otherwise, confirming that the security and demolition unit undertakes accident responsibility;
