Optimistic transactional rollup: feature flag & origination
Context
This MR is the first of a series to introduce optimistic transactional rollups into tezos. The merge process is described here.
This first MR set a feature flag tx_rollup_enable
that is checked for each rollup operation and prevents its application. When all the transactional rollup MR are merged this flag can be entirely removed from the codebase until then it must only be set to true
in tests when activating the protocol with genesis
as a predecessor. The migration process set it to false by default.
It also adds the first operation for the transactional rollups: tx_rollup_origination
. The initiated storage is set to unit for the moment until the next MR because the correct types have not yet been introduced.
This tx_rollup_origination
operation burns currently 15 tez, the maximum an operation is allowed to burn in storage.
this value should be change to a more adequate value later when we have an implementation of the actual storage a tx rollup is going to use. See #2152 (closed)
smart contract rollup first MR : !3941 (merged)
next MR2 on tx rollup: !3921 (closed)
depends on: !3928 (merged)
Manually testing the MR
- Change the default value
tx_rollup_enable
inproto_alpha/parameters/sandbox-parameters.json
totrue
- Runs a sanboxed tezos node and create a new tx rollup with the following command :
tezos-client --wait none originate tx rollup from <source> --storage-limit 60_000
