                Support append for storage contract
              
          
    To further reduce the gas cost of writing data, we can support the appending feature on the storage contract to avoid an additional sstore. Two new functions will be added:

function appendBlob(uint256 _blobIdx, uint256 _length) public payable returns (uint256 kvIndex)
function get(uint256 _kvIndex, DecodeType _decodeType, uint256 _off, uint256 _len) public view virtual returns (bytes memory)

Important
If the appendBlob is used, the application contract will need to remeber the returned kvIndex, and then retrieve the value later using it.

A prototype of implementation will be:
function append(uint256 _blobIdx, uint256 _length) public payable returns (uint256) {
     require(_length <= MAX_KV_SIZE, "DecentralizedKV: data too large");

    Creating your first unstoppable dApp on Ethereum

In this article, we will demonstrate how to deploy the simplest unstoppable dApp using the ethfs-cli tool.
For the content to be deployed, let's assume that:

There is an application folder (e.g., dist), which contains two files inside (e.g., app.html and degen.jpeg).
The app.html file displays a greeting message from a smart contract and a degen image (264KB). It's very simple:

<html>
