Data layers

Table	T0	T1	T2	Description
blocks				Record of all blocks ever stored on chain. Each block is uniquely identified by block_number.
transactions				Record of all transactions ever executed on chain.
events				All events (logs) emitted on the blockchain. For T2 processed chains, includes also reverted events.
calls				Log of all internal transaction calls (traces) executed on the blockchain.
messages				Detailed log of the asynchronous interactions between L2 and L1 via the L2→L1 messaging protocol. Starknet only.
hashed_storage_diffs				Changes made to the storage of smart contracts during on-chain operations, hashed. Starknet only.
state_diffs				Changes made to the blockchain state during on-chain executions.
storage_diffs				Changes made to the storage of smart contracts during on-chain operations (SSTORE), in decoded pre-hashed format.
transient_storage_diffs				Changes made to the transient storage of smart contracts during on-chain operations (TSTORE), in decoded pre-hashed format (EIP-1153)
