Signing privacy marker transactions
You can sign privacy marker transactions with either a random key or a specified key. To sign privacy marker transactions with a specified private key, use
--privacy-marker-transaction-signing-key-file when starting Hyperledger Besu.
In networks where you pay gas, you must specify a key and the associated account must contain adequate funds.
In free gas networks, to provide further anonymity by signing each privacy marker transaction with a different random key, exclude the
--privacy-marker-transaction-signing-key-file command line option when starting Besu.
Using account permissioning and privacy
You cannot use Account permissioning with random key signing.
If using account permissioning and privacy, a signing key must be specified using the
--privacy-marker-transaction-signing-key-file command line option and the signing key included in the accounts allowlist.
Besu signs privacy marker transactions during the private transaction process.
