It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort belong to the protection scope of the embodiments in the present specification.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
Example one
Referring to fig. 1, a schematic step diagram of an upgrading method for a block link point program provided in an embodiment of the present disclosure may include the following steps:
step 101: deploying node upgrading intelligent contracts on the block chain;
step 102: the node upgrading process monitors the event of the node upgrading intelligent contract;
step 103: calling the node upgrading intelligent contract and issuing upgrading program information to a contract address of the node upgrading intelligent contract;
step 104: after monitoring the event of the node upgrading intelligent contract, the node upgrading process downloads an upgrading program;
step 105: the node checks whether the network meets the upgrade requirement;
step 106: and when the network meets the upgrading requirement, the node upgrading process stops the old node service and starts the node service by using the new version node program.
It should be noted that the upgrade program information may further include at least one of an upgrade program download address, an upgrade program digital abstract, and an upgrade version number.
Before downloading the upgrade program, the following steps can be adopted to avoid the repeated upgrade of the nodes: and the node upgrading process reads the upgrading program information, compares the upgrading version number with the version number of the current node program, and downloads the upgrading program through the upgrading program downloading address if the upgrading version number is higher than the version number of the current node program.
In practical application, after monitoring the event message of the node upgrading intelligent contract, the node upgrading process can trigger an out-of-link alarm, trigger an out-of-link alarm (such as a short message and a mail), inform a node administrator and confirm that automatic upgrading can be performed; and a link of manually confirming the upgrade is added, so that the application system butted by the nodes has the flexible time for adapting the new version program.
Before the nodes are formally upgraded, whether the network meets the upgrade requirement needs to be checked; the method can be realized by adopting the following steps:
submitting an upgrade confirm transaction to the blockchain; at this point, the node may update its own state to "in progress";
after the upgrading node inquires the upgrading confirmation transaction chain, judging whether the consensus process can be normally carried out if the self node stops to be upgraded according to the number of nodes participating in voting in the consensus result;
if the consensus process can be normally carried out, judging that the network meets the upgrading requirement; and if the consensus process can not be normally carried out, the node to be upgraded is suspended for upgrading, and the upgrading confirmation transaction is submitted again after delay for network judgment.
Judging whether fault-tolerant seats exist or not according to the number of nodes participating in voting in the consensus result, and assuming that a current block chain uses PBFT as a consensus algorithm, a current network has 4 consensus nodes, all the nodes work normally, the consensus voting of the 4 nodes should be received (at this time, n is 4), which indicates that the current network can tolerate faults (n-1)/3 is 1 node, and at this time, 1 node can be stopped to be upgraded. The node may perform a shutdown upgrade.
After the node upgrading process stops the old node service and starts the node service by using the new version node program, the method may further include: the new version node service participates in consensus after connecting to the network, submits the updated transaction for consensus voting, and can update the node state of the new version node service to be normal, so that the update is completed. Other nodes repeat the complaint process, so that the node upgrading in the whole network can be completed, and the consensus process of the whole network can be kept unaffected.
Through this specification technical scheme, through increasing solitary node upgrading process to the block chain procedure, utilize the intelligent contract of operation on the block chain account book as the configuration center, come to carry out automated upgrade to block chain link point procedure, reduce the fortune dimension degree of difficulty, reduce operating time, reduce the time of shutting down the maintenance and the possibility of making mistakes through reducing artifical link.
