[EPIC] Minimal viable ledger

[scarmuega]

Tasks

• describe and evaluate existing Dolos mechanism for PParams persistence #7
• test: implement PParams blackbox test using Haskell node as test oracle txpipe/dolos#180

Scope/Acceptance Criteria

• Keep track of protocol parameters from a initial configuration & protocol updates tracked from chain-synchronization

  • We mostly need what is sufficient to provide useful feedback when validating transaction on submission, at least:
    • Fee (constant + coefficient)
    • maxValueSize
    • minUtxoDepositCoefficient / minUtxoDepositConstant
    • maxTransactionSize
    • stakeCredentialDeposit
    • collateralPercentage
    • maxCollateralInputs
    • maxExecutionUnits
    • (to be completed as identified)

• At this point, UTxO-tracking is not required, but a nice-to-have. If times allow, we may consider it for this phase otherwise it will be reviewed more carefully in the next.
