Now, save the passphrase you used in the geth node into a text file called password.txt. Then, once you have this private geth node running on your local network, we will need to generate test, pending transactions that can then be processed into shards by validators and collation proposers. For this, we have created an in-house transaction generator CLI tool.

For detailed information on protocol primitives including collations, see: [Protocol Primitives](#protocol-primitives). We will have two types of nodes that do the heavy lifting of our sharding logic: **proposers and collators**. The basic role of proposers is to fetch pending transactions from the txpool, execute any state logic or computation, wrap them into collations, and submit them along with an ETH deposit to a **proposals pool**.

Collators add collations in the proof of work chain, throughout the document named the **canonical chain**. Collators subscribe to updates in the proposals pool and pick a collation in their best interest. Once collators are selected to add collations to the canonical chain, and do so successfully, they get paid by the deposit the proposer offered.

It will be the proposer client’s responsibility to listen to any new broadcasted transactions to the node and interact with collators that have staked their ETH into the SMC through an open bidding system for collation proposals. Proposer clients are the ones responsible for **state execution** of transactions in the tx pool.
