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.
Note
The private key file can be the same file used by
--node-private-key-file, or a different key file to identify who
signed the privacy marker transaction.
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 corresponding public key included in the accounts allowlist.
Note
Besu signs privacy marker transactions during the private transaction process.
