摘要： A method for storing object state on hash chains. A read request that includes a received field name is received by an object with a plurality of fields. A field value that corresponds to the received field name is retrieved from a hash chain of the object by traversing the hash chain. A block is found that includes the field value from the plurality of field values that corresponds to the received field name. A response to the read request that includes the field value is generated and transmitted.

摘要： A method for storing object state on hash chains. A block of a hash chain is located with an accessor function. The block includes a field value of a field of an object. Version data is located using the block. The version data identifies a block version of the block. The block version is compared to a function version of the accessor function. The field value from the block is returned when the block version matches the function version. A version matched accessor function is called to return the field value when the block version does not match the function version.

摘要： A method for message management is disclosed. The method includes: deriving, by a first subscriber node (SN), a secret value associated with a publisher node (PN); generating, by the first SN, a first expected sequence number using a one-way function and the secret value; receiving, by the first SN, a first publisher message generated by the PN and including a first sequence number; validating, by the first SN, the first publisher message by comparing the first sequence number with the first expected sequence number; processing, by the first SN, a payload of the first publisher message in response to the first sequence number and the first expected sequence number matching; and generating, by the first SN node, a second expected sequence number using the one-way function, the first sequence number, and the secret value.
