Calibrate Cardano transaction signature parameters

[jpraynaud]

Why

We need to calibrate the new parameters introduced by the new Cardano transaction type, and also identify the impact of modifying these parameters after the launch.

What

Prepare parameters for 1 round of signature every 10 minutes, 30 minutes behind the tip:

• cardano_transactions_prover_cache_pool_size: 5
• cardano_transactions_database_connection_pool_size: 10
• cardano_transactions_block_streamer_max_roll_forwards_per_poll: 10000
• cardano_transactions_signing_config:

CardanoTransactionsSigningConfig {
  security_parameter: 100,
  step: 30,
}

How

• Make parameters configurable via the CD:
  • cardano_transactions_prover_cache_pool_size
  • cardano_transactions_database_connection_pool_size
  • cardano_transactions_signing_config
• Deploy parameters to networks:
  • testing-mainnet
  • testing-preview
  • testing-sanchonet
  • pre-release-preview
  • release-preprod
  • release-mainnet
• Evaluate probability of rollback with parameters

According to this resource, here is the rollback probability we can expect:

Grinding Power	Adversarial Stake	Depth from tip	Rollback probability
10^9	5%	100	0.0001%
10^9	7.5%	100	0.01%
