Abstract

A novel blockchain network architecture and transaction processing workflow, collectively referred to as the oracle-driven blockchain approach, is disclosed. In certain embodiments, this approach enables a blockchain network to efficiently execute and validate transactions that require answers from an oracle by (1) separating block creation from transaction execution (such that each new block to be added to the network's blockchain is first created by one or more sequencing nodes before any of the transactions within the block are actually executed), and (2) ensuring that, as part of transaction execution, any output generated by the oracle which changes state is added to a transcript that is included within the block.

Claims20

Dependent claims

A method performed by a blockchain network comprising a plurality of nodes, the method comprising:

selecting, by a sequencing node in the plurality of nodes, a set of transactions from a transaction pool, the set of transactions including a first transaction that requires an output from an oracle;
ordering, by the sequencing node, the set of transactions;
executing, by the sequencing node, the ordered set of transactions in order, wherein the executing involves using a predetermined value for the output from the oracle rather than invoking the oracle to obtain the output;
adding, by the sequencing node, the ordered set of transactions and state information pertaining to a result of the executing to a non-canonical block;
and
broadcasting, by the sequencing node, the non-canonical block to the plurality of nodes.

A non-transitory computer readable storage medium having stored thereon program code executable by a blockchain network comprising a plurality of nodes, the program code embodying a method comprising:

selecting, by a sequencing node in the plurality of nodes, a set of transactions from a transaction pool, the set of transactions including a first transaction that requires an output from an oracle;
ordering, by the sequencing node, the set of transactions;
executing, by the sequencing node, the ordered set of transactions in order, wherein the executing involves using a predetermined value for the output from the oracle rather than invoking the oracle to obtain the output;
adding, by the sequencing node, the ordered set of transactions and state information pertaining to a result of the executing to a non-canonical block;
and
broadcasting, by the sequencing node, the non-canonical block to the plurality of nodes, thereby causing each node in the plurality of nodes to add the non-canonical block as a head block to a local blockchain copy maintained by the node.

3 more elements

A computer system acting as a sequencing node in a blockchain network comprising a plurality of nodes, the computer system comprising:

one or more processors;
and
a non-transitory computer readable medium having stored thereon program code that, when executed, causes the one or more processors to:
select, by a sequencing node in the plurality of nodes, a set of transactions from a transaction pool, the set of transactions including a first transaction that requires an output from an oracle;
order, by the sequencing node, the set of transactions;
execute, by the sequencing node, the ordered set of transactions in order, wherein the executing involves using a predetermined value for the output from the oracle rather than invoking the oracle to obtain the output;
add, by the sequencing node, the ordered set of transactions and state information pertaining to a result of the executing to a non-canonical block;
and
broadcast, by the sequencing node, the non-canonical block to the plurality of nodes, thereby causing each node in the plurality of nodes to add the non-canonical block as a head block to a local blockchain copy maintained by the node.
