Ethereum Dencun Upgrade EIP-4844: Everything You Need to Know About
Proto-Danksharding Unleash the Power of Dencun Behold the new Ethereum Dencun
Upgrade has arrived!   As a community of blockchain enthusiasts, we are always
excited about the latest upgrades in Ethereum. One such groundbreaking upgrade
is the Ethereum Dencun. In this comprehensive guide, we will delve deep into the
intricacies of the Ethereum Dencun Upgrade, explore its features and benefits,
and understand the revolutionary concepts of EIP-4844 and Proto-Danksharding.
So, let’s embark on this journey to unravel the future of Ethereum. Table of
Contents What is Ethereum Dencun Upgrade? Before we dive into the details, let’s
familiarize ourselves with the basics of Ethereum Dencun Upgrade. So, the Dencun
is an upgrade that aims to enhance the scalability and efficiency of the
Ethereum network. It introduces innovative solutions to address the challenges
faced by the existing Ethereum infrastructure, such as high transaction fees and
slow transaction processing speed. It’s not only aimed at making changes to the
Ethereum itself but it will also affect all the Layer 2 networks, by offering a
brand new way of storing and sharing data. What does it consist of? Ethereum
Dencun upgrade consists of two major components: Deneb (for the Consensus layer)
and Cancun (for the Execution layer). This dream team of updates brings
significant changes to Ethereum’s inner infrastructure, by changing the way both
beacon nodes and execution nodes operate between each other, sharing and storing
data.  Deneb: Targets the Consensus Layer, aiming to boost network security and
validator efficiency. Cancun: Focuses on the Execution Layer, introducing
enhancements that improve transaction processing and smart contract
capabilities. EIPs included in Dencun Upgrade So, the Dencun Upgrade involves 9
Ethereum Improvement Proposals (EIPs). Here is the breakdown of all the EIPs
included in Deneb and Cancun upgrades that are combined together forming the
Dencun:  Deneb EIPs: EIP-7044: Simplifies the process of validators exiting and
withdrawing the stacker funds. EIP-7044 adds perpetually valid signed voluntary
exits allowing simpler staking operation designs. EIP-7045: Increases the
maximum inclusion slot for attestations following the learned security proof and
confirmation rule needs. In simple words, it enhances the period during which an
attestation can be included in a consensus Beacon Chain block.  EIP-7514:
Updates the maximum validator growth rate from an exponential to a linear
increase by limiting the epoch churn limit. The Beacon chain spec can handle
this without issues.  Cancun EIPs: EIP-1153: Introduces transient storage
opcodes, which manipulate state that behaves identically to storage, except that
transient storage is discarded after every transaction. Transient storage is
accessible to smart contracts via 2 new opcodes, TLOAD and TSTORE, where “T”
stands for “transient:” EIP-7516: Adds a BLOBBASEFEE (0x4a) instruction that
returns the value of the blob base-fee of the current block it is executing in.
It is identical to EIP-3198 (BASEFEE opcode) except that it returns the blob
base fee as per EIP-4844. EIP-5656: Proposes a new EVM instruction called MCOPY
for efficiently copying memory areas within the EVM. It’s designed to reduce the
overhead involved in memory copying operations . EIP-6780: Changes the
functionality of the SELFDESTRUCT opcode. The new functionality will be only to
send all Ether in the account to the target, except that the current behavior is
preserved when SELFDESTRUCT is called in the same transaction a contract was
created. Dencun EIPs There are several Ethereum Improvement Proposals that are
both changing Consensus and Execution layers together. They are also the most
important and game-changing improvements. EIP-4844: The most awaited improvement
proposal is the EIP 4844. It introduces “shard blob transactions,” which are a
new type of transaction designed to handle larger and more complex data
structures. This enables Ethereum to support a broader range of applications and
use cases by allowing transactions with 128KB ephemeral data blobs to drop after
3 weeks, resulting in no long-term storage usage . EIP-4788: Includes the
storage of cryptographic accumulators, known as roots, of the blocks in the
beacon chain within the EVM. Exposing these roots inside the EVM allows for
trust-minimized access to the consensus layer. This functionality supports
various use cases that improve trust assumptions of staking pools, restacking
constructions, smart contract bridges, MEV mitigations, and more. Now, as we
unveiled and structured all the EIPs included in Dencun Upgrade, let’s dive
deeper into the most important and exciting one – EIP-4844.  What is EIP-4844?
EIP-4844 is “one small step for man, one giant leap for mankind” in the context
of Ethereum scalability and data sharding. This Ethereum Improvement Proposal
greatly closes the day when full data sharding becomes a reality.  EIP-4844 is
crucial for Ethereum as it continues to seek scalable solutions to accommodate
its growing user base and reduce transaction costs, which are still
prohibitively high for many users. Some of the components of EIP-4844 such as
Proto-Danksharding allow to significantly decrease the cost of data storage for
Ethereum’s layer 2 rollups. This is achieved through the introduction of data
“blobs” which enable rollups to post data to Mainnet for a short time. This
results in significantly lower transaction fees for users of layer 2 rollups.
Although high gas prices are still a big concern for the Web3 world, there are
lots of scaling solutions that can already significantly decrease fees for many
Ethereum users. For example, optimistic rollups such as Optimism, Base, and
Arbitrum can offer ~3-10x lower fees than Ethereum itself. As well as ZK
rollups, such as zkSync, Starknet, Linea, and many others, which have better
data compression and can stay away from including signatures, have fees ~50-100+
times lower than the base layer. However, even these reduced fees are too costly
for many users. The ideal answer to this issue has always been data sharding,
which would provide approximately 16 MB per block of exclusive data space that
rollups could use. However, many improvements must be made until full data
sharding is achieved. To deal with these issues EIP-4844 proposes a temporary
solution by introducing a transaction format intended for sharding, without
actually sharding transaction data. Instead, the data from this transaction
format is just a piece of the beacon chain and is completely downloaded by all
consensus nodes. Moreover, this data can be deleted after only a fairly short
delay. Unlike full data sharding, this EIP sets a cap on the volume of such
transactions per block, aiming for around 0.375 MB and capping at approximately
0.75 MB. Proto-Danksharding: What are Data Blobs? As it is said, the core
feature of the EIP-4844 is the Proto-Danksharding which is the introduction of
data “blobs“. This exciting improvement enables rollups to post data to Mainnet
for a short period. This results in significantly lower transaction fees for
users of layer 2 rollups. So, what are exactly data blobs? Data blobs, as
introduced in Ethereum’s EIP-4844, are essentially large chunks of data that can
be attached to transactions. These blobs are designed to enhance Ethereum’s
scalability by allowing more data to be included in each block without
significantly increasing transaction costs.  Blobs are data packets in which
full information about the L2 transaction block is written. In this case, the
blob is stored outside the execution layer, i.e. the EVM has no direct access to
the data in the blob. Developers use the concept of a sidecar to describe the
concept because a blob is “attached” to a block like a sidecar to a motorcycle.
The data within these blobs is not required to be retained by consensus nodes,
although a form of cryptographic proof of their previous existence remains.
Previously, rollups used calldata to write transaction bundle data. Although
calldata stored smaller data volumes and was cheaper, this information was about
to stay on nodes practically forever, leading to data accumulation and increased
node requirements. Since the EIP-4844 came to the network, rollups don’t have
any choice but to use data blobs because sharded data will be much cheaper.
Blobs are meant to be transient and unlike the calldata only available for a
limited period of time (about 18 days) after which the data within is no longer
retrievable by consensus clients. However, a cryptographic “fingerprint” of the
blob, known as a KZG commitment, remains on the mainnet. KZG commitments ensure
that despite the short-lived nature of blob data, its integrity can still be
verified, which is crucial for maintaining trust in the network’s operations.

with Postman.  Common instructions for sending Postman WebSocket requests Once
you have set up Postman and got your API key for WebSocket testing, you can
start sending WebSocket requests.  Follow these steps to send a WebSocket
request using Postman: Follow the Postman interface: find the “NEXT” point and
choose the “Websockets” to open a new tab specifically for WebSocket requests.
Select the request type: In the request builder, choose the “WebSocket” option
from the drop-down menu next to the URL input field.  Enter the WebSocket URL:
Specify the WebSocket URL in the URL input field. Make sure to include the
“ws://” or “wss://” protocol prefix, followed by the host and port. For example,
NOWNodes provides “wss://:” protocol prefixes, that you can find on the “NODES”
page. Customize the request: If needed, you can customize the WebSocket request
by adding headers, query parameters, or request bodies. This allows you to
simulate different scenarios and test specific aspects of your WebSocket
implementation. Send the request: Click the “SEND” button to send the WebSocket
request. Postman will establish a WebSocket connection and display the response
in the response panel. You can analyze the response and verify that your
WebSocket implementation is working as expected. Configuring WebSocket
Connections in Postman Postman provides various options to configure WebSocket
connections and handle different scenarios. Here are some advanced techniques
for configuring WebSocket connections in Postman: Authentication: If your
WebSocket server requires authentication, you can include authentication headers
in your request. Postman allows you to set custom headers and authenticate your
WebSocket requests accordingly. SSL/TLS support: Postman supports SSL/TLS
connections for secure WebSocket testing. You can specify the “wss://” protocol
prefix and configure any necessary SSL/TLS settings to establish a secure
connection. Connection timeouts: In some cases, you may want to set a specific
timeout for your WebSocket connections. Postman allows you to configure
connection timeouts to ensure that your requests do not hang indefinitely.
Remember to refer to the WebSocket API documentation to understand the specific
protocols, message formats, and authentication requirements for your
connection.  Now as you know common issues that allow you to test websockets in
Postman, we are going to show you examples of Postman testing with NOWNodes.

the capabilities of NOWNodes, a leading provider of blockchain API services, we
will demonstrate how Postman can be used to test and validate various API
endpoints, making it an invaluable tool for developers in the blockchain space. 
We are going to explore and test the Ethereum WebSocket connection. Ethereum
WebSocket API Connection To test the Ethereum WebSocket response in Postman, you
can follow these steps. Set the request method to “POST” and enter the WebSocket
URL in the request URL field. For example, if you are using NOWNodes, the URL
would be  wss://eth.nownodes.io/your_api_key  Go to the “Headers” tab and add a
new header with the key “Content-Type” and value “application/json“. Go to the
“Body” tab and select the “raw” option. Enter the JSON payload for the WebSocket
request. For example, to subscribe to new block headers, you can use the
following payload: {   "jsonrpc": "2.0",   "id": 1,   "method": "eth_subscribe",
  "params": ["newHeads"] } Click on the “Send” button to send the WebSocket
request. Postman will establish a WebSocket connection and display the response
in the “Response” panel. The response will contain the data you subscribed to,
such as new block headers in the case of the example payload above. Bitcoin

How to Utilize Kava EVM RPC API Methods? A Complete Guide Get Access to Kava EVM
Being EVM-compatible while born on the combination of Cosmos SDK and Tendermint
Consensus, the Kava network has emerged as a significant player in the
blockchain market, offering unique opportunities for developers and users alike.
As the blockchain industry continues to evolve, the demand for interoperability
and scalability solutions will grow rapidly. It opens great opportunities for
Solidity developers who choose Kava as the platform to build dApps on, as they
can benefit from the scalability and security of the Kava Network while sticking
to the familiar development process. In this guide, we’ll delve into the Kava
network, introduce the Kava EVM, and provide a comprehensive walkthrough on the
process of accessing and utilizing Kava EVM RPC methods with the help of
NOWNodes. Keep reading to unlock the full potential of the Kava blockchain.
Table of Contents What is Kava Network? Kava is a decentralized blockchain that
combines the speed and interoperability of Cosmos with the developer power of
Ethereum.  The Kava network is a groundbreaking blockchain platform designed to
power a wide array of DeFi applications and services. Built on the Cosmos SDK,
it leverages the interoperability and scalability of the Cosmos ecosystem, known
as the “Internet of Blockchains.” Moreover, the Kava Network provides an
EVM-compatible execution environment that empowers Solidity developers and their
dApps to benefit from scalability and security. Kava uses the Tendermint
consensus mechanism, renowned for its robustness and reliability. With
single-block finality and supreme scalability, Tendermint Consensus allows Kava
to keep the transaction needs of thousands of protocols and millions of users. 
The Kava Networks also has its native token KAVA. This token is integral to the
security, governance, and mechanical functions of the platform. There are three
main use cases for the KAVA token: Security The Kava Blockchain employs
Proof-of-Stake (PoS) validation, where nodes in the network, referred to as
“validators”, are selected based on the number of KAVA tokens they stake.
Governance KAVA is used for proposals and voting on critical parameters of the
Kava Network. KAVA token holders help fuel growth on the network by staking
their KAVA to vote on KavaDAO proposals that control the network’s resources
Incentives A portion of KAVA emissions is distributed as incentives for scaling
the network. These incentives go directly to top projects on each chain to drive
growth, encourage competition, and improve the health of the Kava ecosystem.
What is the Co-Chain Architecture of the Kava Network?  The combination of
Ethereum EVM and Cosmos SDK is what makes Kava Network different from other
blockchains. This strategic alliance lets developers familiar with Solidity
migrate their Ethereum-based applications to the Kava network, profiting from
improved efficiency, security, and the extensive benefits of the Cosmos
ecosystem.  All that was made possible due to the robust Co-Chain Architecture
and The Translator Module. KAVA’s co-chain architecture enables developers to
build and deploy their applications and smart contracts using either the EVM or
Cosmos SDK execution environments with seamless interoperability between the
two.  The Kava Network Co-Chain Architecture consists of two main components:
the Ethereum Co-Chain and the Cosmos Co-Chain. The Ethereum Co-Chain part is
responsible for building dApps and smart contracts. It allows developers to
deploy Ethereum-based applications and smart contracts directly on Kava without
any modifications. While the Cosmos Co-Chain part is aimed at cross-chain
communications. It is perfectly suitable for building high-performance,
interoperable applications and enables Kava to connect with other blockchains
within the Cosmos network through the IBC (Inter-Blockchain Communication)
protocol, promoting cross-chain asset transfers and communication. Both parts of
the Architecture are connected by the Translator Module. It acts as a bridge,
translating and transferring information between the two co-chains, which have
different data structures, consensus mechanisms, and transaction formats. What
is Kava EVM? Introduction to Kava EVM At the heart of Kava’s expansion into the
Ethereum ecosystem is the Kava EVM – an Ethereum Virtual Machine implementation
that facilitates the deployment and execution of Ethereum-compatible smart
contracts on the Kava network. This compatibility layer bridges the gap between
the Cosmos and Ethereum communities, allowing developers to leverage Ethereum’s
rich development tools and languages, such as Solidity, within the scalable and
interoperable Kava ecosystem. This Ethereum compatibility provides huge benefits
for developers who are familiar with building on Ethereum, as Kava EVM utilizes
the same JSON RPC methods to interact with the node.   Ethereum’s compatibility
on Kava EVM significantly lowers the entry barrier for Ethereum developers,
enabling them to leverage their existing codebases and expertise in a new
environment. It’s like moving to new apartments with the old furniture, but even
much easier, because all your needed stuff is already waiting for you there.
There are many benefits and exciting features that Kava EVM offers for Web3
developers. Some of the most common key features are:  Velocity and Efficiency:
With a block mining time of just 6 seconds and finality achieved in just one
block, the Kava EVM offers quick and effective transaction execution. Safeness
and Scalability:  Anchored by Kava’s Tendermint consensus mechanism, the
infrastructure is both robust and capable of scaling, housing a broad spectrum
of dApps and significant volumes of transactions. Interoperability and
Integration with the Cosmos Ecosystem: Being a part of the Cosmos ecosystem,
Kava EVM benefits from the seamless interoperability provided by the Cosmos SDK.
For Web3 developers, this interoperability opens up a multitude of possibilities
for cross-chain applications and services, enabling them to tap into liquidity,
users, and functionalities across multiple blockchain ecosystems. Economic and
Operational Efficiencies: Transaction costs on the Kava EVM can be more
predictable and often lower than those on Ethereum’s mainnet, particularly
during periods of network congestion. Kava EVM effectively blends the powers of
Ethereum with the outstanding advantages of the Cosmos SDK and the Kava network,
forming an adaptable and effective Web3 platform for dApp development. How to

from 1 Million on a PRO plan to an UNLIMITED number of interactions with the
blockchain node on a DEDICATED one!  How to Interact With Kava EVM Node Using
JSON RPC Methods Interacting with the Kava EVM node involves utilizing JSON RPC
methods, a standard protocol for invoking functions on a remote server. Here’s
how to get started: Choose Your Tool: Decide on a tool for sending JSON-RPC
requests, such as cURL for command-line interfaces, Postman for a graphical
interface, or Web3.js/Ethers.js for integration into JavaScript applications.
Formulate Your Request: Construct a JSON object specifying the jsonrpc version
(usually “2.0”), the method you wish to call, any necessary params, and of
course, don’t forget your <api-key> to authenticate your access to the node, and
a provided  kava-evm.nownodes.io endpoint to interact with the Kava EVM node.
Send the Request: Use your chosen tool to send the request to the Kava EVM node
endpoint.  Handle the Response: Process the JSON response from the node, which
contains the result of your RPC call. This could be information like the latest
block number, the balance of an account, or the receipt of a submitted
transaction. There are a variety of ETH JSON RPC methods available to interact
with the Kava EVM node. Now let’s take a look at some of the basic methods of
EVM like eth_blockNumber, which returns the current latest block number. Here’s
the sample request:  curl --request POST \ --url
https://kava-evm.nownodes.io/<api-key> \ --header 'Content-Type:
application/json' \ --data '{ "jsonrpc": "2.0", "method": "eth_blockNumber",
"params": [], "id": 1 }' So, the response will show the latest mined block in
the Kava blockchain in hexadecimal numbers,  and it might be:  { "jsonrpc":
"2.0", "id": 1, "result": "0x87abdf" } In this example, the latest block is
8891359th. Moreover, this method could be used to check if your connection to
the node is correct. If the latest block that you see is up-to-date, then you’re
fine and can start sending more complex requests. Now let’s check another
classical Ethereum JSON-RPC API method eth_getBlockByHash  that can be utilized
on Kava EVM for querying sophisticated information about a specific block by its
given hash.  Here’s the sample request:  curl --request POST \ --url
https://kava-evm.nownodes.io/<api-key> \ --header 'Content-Type:
application/json' \ --data '{ "jsonrpc": "2.0", "method": "eth_getBlockByHash",
"params": [
"0x53a5e82253d2179241d1bff69c37be423f52902c459b5c5ee41280098bb80850", false ],
"id": 1 }' This method provides detailed data about a specific block identified
by its hash. It includes the maximum amount of gas that could have been used by
the transactions in the block, the total amount of used gas, the address of the
validator who mined the block, the block number in hexadecimal, the timestamp
when the block was mined, the array of transactions included in the block and
more. Here’s the sample response for the hash provided in the example: {
"jsonrpc": "2.0", "id": 1, "result": { "difficulty": "0x0", "extraData": "0x",
"gasLimit": "0x1312d00", "gasUsed": "0x2f26a", "hash":
"0x53a5e82253d2179241d1bff69c37be423f52902c459b5c5ee41280098bb80850",
