Neutralization‌

This version introduces the support for two Ethereum major upgrades: Cancun and Prague. Since this repository starts from and still is an Execution Layer (EL), this upgrade is only a part of Dencun and Pectra. As a result, the proposal of EIP-4844 (Shard Blob Transactions) are not fully implemented. Currently, blob data is only very short-lived in the network, and doesn't have any API to get properly accessed.

Follow the instructions below to upgrade your node from v0.4.2 to v0.5.0:

1. Download new binary and new genesis configuration file from the release page.
2. Gracefully stop the node.
3. Replace the old binary with the new binary.
4. For TestNet nodes only: reinitialize DB using new binary and new genesis configuration file with the following command:

   ## If you are running a full node, don't remove DB.
   ./geth init --state.scheme hash --datadir ./node-datadir ./config/genesis.json
   
   ## If you are running a snap node, you can reserve the DB by reiniting with "--state.scheme hash".
   ## Or, remove existing DB and init a new one with "--state.scheme path" as default.
   ./geth removedb --datadir ./node-datadir
   ./geth init --datadir ./node-datadir ./config/genesis.json
   

5. Start the node with --state.scheme set to hash or path (default)
   correspondingly.
