Deploy Cardano transactions to `testing-mainnet` about mithril

[jpraynaud]

Activation of the signature of the Cardano Transactions

(on the testing-mainnet network)

Aggregator:

• Import of 90M transactions (10M blocks)
• Generation of 675K block range roots
• Import + generation done in 21h (less than 10min for the generation of block range roots)
• Resources needed by the signer were low: 55MB RES and ~30-50% one core CPU
• Database size of 26GB
• No new open message created during the import (network stuck)

Signer:

• Started import after the aggregator computed the first CardanoTransactions open message (~22h)
• Import of 90M transactions (10M blocks)
• Generation of 675K block range roots
• Import + generation done in 21h (less than 10min for the generation of block range roots)
• Resources needed by the signer were low: 55MB RES and ~30-50% one core CPU
• Database size of 26GB (will be pruned so we expect ~1-2GB then)
• No new open message signed during the import (network stuck)

The network is stuck for 2 days once the signature of the transactions is activated: we need to have a warm-up mode for the nodes in order to import the transactions without preventing the Mithril network to create new certificates.

Once the initial import is done, the overall signature process takes only few minutes.
