Transactions per block?

[melpadden]

From @GuybrushX:

How many transactions (formerly deploys, I think it got renamed?) are possible per block?

Transactions within a block are categorized into multiple lanes.

Defined in this block of chainspec:

[transactions.v1]
# The configuration settings for the lanes of transactions including both native and Wasm based interactions.
# Currently the node supports two native interactions the mint and auction and have the reserved identifiers of 0 and 1
# repsectively
# The remaining wasm based lanes specify the range of configuration settings for a given Wasm based transaction
# within a given lane.
# The maximum length in bytes of runtime args per V1 transaction.
# [0] -> Transaction lane label (apart from the reserved native identifiers these are simply labels)
# Note: For the given mainnet implementation we specially reserve the label 2 for install and upgrades and
# the lane must be present and defined.
# Different casper networks may not impose such a restriction.
# [1] -> Max transaction size in bytes for a given transaction in a certain lane
# [2] -> Max args length size in bytes for a given transaction in a certain lane
# [3] -> Transaction gas limit size in bytes for a given transaction in a certain lane
# [4] -> The maximum number of transactions the lane can contain
native_mint_lane = [0, 1024, 1024, 65_000_000_000, 650]
native_auction_lane = [1, 2048, 2048, 362_500_000_000, 145]
wasm_lanes = [[2, 1_048_576, 2048, 1_000_000_000_000, 2], [3, 262_144, 1024, 100_000_000_000, 3], [4, 131_072, 1024, 50_000_000_000, 5], [5, 8_192, 512, 1_500_000_000, 15]]

Legacy transactions will fall into one of the wasm_lanes and will be limited until converted to transaction_v1.
