Efficient validation for blockchain

A system, comprising:

• a blockchain network, which comprises:
• one or more blockchain nodes that validate blockchain transactions, each comprises:
• a processor;
• and
• a memory device, coupled to the processor, which comprises:
• a validation database, which comprises:
• data that corresponds to a predetermined number of most recent blocks of a blockchain;
• the processor configured to:
• simulate each of one or more transactions;
• determine that each transaction in a new block may be validated using the validation database;
• validate each transaction in the new block using the validation database;
• and
• commit the new block to the blockchain.

A non-transitory computer readable medium comprising instructions, that when read by a processor, cause the processor to perform:

• creating, by a blockchain node, a validation database in a memory, the validation database comprising data corresponding to a predetermined number of most recent blocks of a state database for a blockchain;
• simulating each of one or more transactions;
• determining that each transaction in a new block may be validated using the validation database;
• validating each transaction in the new block using the validation database;
• and
• committing the new block to the blockchain.
