Abstract

A massively scalable blockchain ledger without scalability issue on each blockchain node and the blockchain ledger itself by partitioning the full value range of the cryptographic hash of the blockchain blocks into a configurable but large number of block buckets and auto-assign and auto-adjust these buckets roughly evenly amongst reliable blockchain mining nodes.

Claims

1. A massively scalable blockchain ledger is an optimization to the blockchain to achieve massively scalable blockchain ledger by partitioning the full value range of the cryptographic hash of the blockchain blocks into a configurable but large number of block buckets and auto-assign and auto-adjust these buckets roughly evenly amongst reliable blockchain mining nodes;

wherein on joining the blockchain, a new node expresses its willingness to host the ledger and when a node is unreachable, detected via missing of heartbeat messages or activities, all current nodes marks this unreachability.

2. A massively scalable blockchain ledger according to claim 1, wherein each node evaluates its peers'"'"' activities and decides the reliable set of ledger nodes locally preferred. Furthermore, the auto-elected and auto-adjusted master node proposes ledge nodes and multicasts that proposal to all other nodes, which evaluates the proposal against its observation, decides whether to endorse or not.

3. A massively scalable blockchain ledger according to claim 1, wherein when collected endorsement from ⅔

of the current reliable nodes, the acting master node sends the decided ledge nodes list with endorsement proof. On receiving the decision, each node verifies the decision and rebalances its block hosting if necessary.

4. A massively scalable blockchain ledger according to claim 1, wherein each ledger nodes randomly selects a block bucket it hosts and multicasts all blocks in it to all other nodes to prove its possession of all blocks in the block bucket.

5. A massively scalable blockchain ledger according to claim 1, whenever a node requires a remote block, it would figure out the current nodes hosting it based on the ledger scaling strategy, then contact the corresponding node(s) directly for data of that block.

6. A massively scalable blockchain ledger according to claim 1, wherein rf (balancing and redundancy factor) nodes are assigned to host a given block bucket and as part of the scaling strategy, they are auto-chosen and auto-adjusted to be preferably geographical distributed with redundancy in each location.
