Sending concurrent private transactions
Private transaction processing involves two transactions, the private transaction and the privacy marker transaction. The private transaction and the privacy marker transaction each have their own nonce.
If your private transaction rate requires sending private transactions without waiting for the previous
private transaction to be mined, you must use priv_distributeRawTransaction
instead of eea_sendRawTransaction. When
using priv_distributeRawTransaction
you create and send the privacy marker transaction yourself rather than eea_sendRawTransaction
handling the privacy marker transaction.
The web3js-eea library includes an example of how to send concurrent private transactions.
Tip
The example
uses offchain privacy groups.
Use priv_getPrivacyPrecompileAddress
to get the precompile address to specify in the to field when creating the privacy marker transaction.
