Solana Validator 101: Transaction Processing

High-level of transaction flow in Solana.

Transaction Processing Unit

Validator & TPU Overview
Multiple batches can be processed at the same. When the bottom pipeline fails to grab a lock on c, it will buffer it for the next iteration.
Executed batches also need to be parallelizable.
output = "solana summer"
while 1:
output = hash([output])
output = "solana summer"
record_queue = Queue()
while 1:
record = record_queue.maybe_pop()
if record:
output = hash([output, record])
output = hash([output])
