- Will it reconnect to the ethereum network upon establishing internet connection again automatically and sync Data ?
- Can we perform transaction and calls on the offline(no internet connection) ethereum node specifically ? suppose we have direct access to that particaular node and we can directly intereact with it.
1- once reconnected your node will continue syncing data (downloading the missing blocks)
2- you can create a transaction offline and sign it then broadcast it later when the internet comes back. you may use this offline node to call a constant function (if it has a synced version of the blockchain) and get back the calculation result.
