 Here the hexadecimal value `0x2a` translates to decimal as `42`, the number of blocks received by the node so far, about two minutes after the new network started.
 
+## Public transactions
+
+This example uses the [web3.js](https://www.npmjs.com/package/web3) library to make the API calls, using the `rpcnode` that is accessed on `http://localhost:8545`
+
+Navigate to the `smart_contracts` directory and deploy the public transaction:
+
+```bash
+cd smart_contracts
+npm install
+node scripts/public/public_tx.js
+# or via ethers
+node scripts/public/public_tx_ethers.js
+```
+
+This deploys the contract and sends an arbitrary value (`47`) from `Member1` to `Member3`.
+
+Once done, it performs a read operation on the contract using the `get` function and the contract's ABI, at the address specified.
+
+It then performs a write operation using the `set` function and the contract's ABI, at the address and sets the value to `123`.
+
+Lastly, it performs a read operation on all events emitted.
+
+```bash
+node scripts/public/public_tx.js
+{
+  address: '0x03e034D03b04A348143F2C25884e1E4946fa6196',

+Use the smart contracts 'get' function to read the contract's constructor initialized value .. 
+Obtained value at deployed contract is: 47
+Use the smart contracts 'set' function to update that value to 123 .. 
+Set value on contract at : 0xdcaf84bbdd35811820dbb13453e1532d5cd3e3ef718e12a49878de67948e0b9b

+We also have a second example to show how to transfer eth between accounts. Navigate to the `smart_contracts` directory and deploy the `eth_tx` transaction:

+```bash
+cd smart_contracts
+npm install
+node scripts/public/eth_tx.js

+Account A has balance of: 90000
+Account B has balance of: 0

+Account A has an updated balance of: 89999.999999999999999744
+Account B has an updated balance of: 0.000000000000000256

 ## Private transactions
 
 This example uses the [web3.js](https://www.npmjs.com/package/web3) library to make the API calls, creating three member nodes pairs (a GoQuorum node which has a corresponding Tessera node for privacy) that can be accessed using APIs on the following ports:
