Identifying the first container may include identifying a set of node configuration parameters associated with the particular node implemented by the first container, and a set of container configuration parameters associated with the first container. The system may request instantiation of a second container, where configuration parameters of the second container may be based on the container configuration parameters associated with the first container. The system may modify a network interface of the virtualized environment, which is associated with the first container, to be associated with the second container in lieu of the first container. The second container may communicate with the other nodes via the network interface to maintain the distributed ledger. ## Claims ### Claim 1 A device, comprising: one or more processors configured to: identify a first container of a virtualized environment, wherein the first container implements a particular node of a plurality of nodes that maintain a distributed ledger, wherein identifying the first container includes identifying: a set of node configuration parameters associated with the particular node implemented by the first container, and a set of container configuration parameters associated with the first container;
