Methods and devices for compressing transaction identifiers by a first mining node in a blockchain network. The method may include building a first candidate block containing a first ordered list of transaction identifiers; receiving, from a second mining node, data defining a second ordered list of transaction identifiers in a second candidate block being mined by the second mining node; determining that at least one of the transaction identifiers in the first ordered list is also in the second ordered list; generating an append message containing data defining the first ordered list of transaction identifiers, wherein the data specifies said at least one transaction identifier in the first ordered list of transaction identifiers by including an index position of said at least one transaction identifier in the second ordered list of transaction identifiers; and transmitting the append message to the second mining node.

Methods and systems for streaming block templates with cross-references

The present disclosure relates to a computer implemented method of maintaining a status of a stream on a blockchain. The method includes, receiving a create stream message, the create stream message comprising an indication of at least one trigger condition. Then, based on a trigger condition being met, the method includes obtaining data indicative of a state of the stream, and generating an append transaction comprising the data indicative of the state of the stream.
