Ethereum's scalability on the base layer is limited by the block gas limit rather than the block size. There is an upper threshold on the amount of gas that can be expended in a block with 30 million gas being the absolute maximum.
Beginning in mid, Ethereum introduced variable-size blocks EIP discussed in detail later. Each Ethereum block targets a size of 15 million gas but the size of blocks will increase or decrease in response to network demand but will not surpass the 30 million limit. Increasing the gas limit and therefore the block size allows for higher performance the possibility of more transactions per second but it also accelerates the amount of state stored on the mainchain, also sometimes called "chain bloat.
Off-chain scaling refers to scaling solutions that use external execution layers rather than the base layer. Ethereum is pursuing both off-chain and on-chain scaling strategies. In essence, the Ethereum upgrade will make the network more scalable, sustainable, and secure. Any human enterprise which is highly successful early on will quickly have to address how to do more to keep up with demand. This is a good problem to have, but not an easy one to solve because scaling up often challenges the core values that made the enterprise successful.
Ethereum, as we know it today, won't scale. Meaning, the Ethereum L1 is designed to remain a highly decentralized, global settlement layer above all else. However, Ethereum's web of L2s will be responsible for scaling Ethereum and serving as its execution layer. These layers will absorb much of the existing value on Ethereum mainnet plus future inflows as Ethereum adoption grows. It's important to understand that Ethereum's web of L2s is a marketplace of independent projects competing with each other to help scale Ethereum.
The scalability trilemma is a well-known issue among all blockchains. A blockchain can achieve two of these traits but at the expense of the third. Many alternative layer 1 L1 chains have chosen to sacrifice decentralization for scalability and security. It provides the chain anti-fragility, robustness, reliability, and censorship resistance.
The goal is to increase the number of transactions while retaining sufficient decentralization. What are the decentralization sacrifices tradeoffs other smart contract L1s have made? Other chains typically make two sacrifices. Obviously, a network that can only be verified if you have X amount of dollars in computing budget is not an ideal, permissionless system.
Another tradeoff often considered is for the network to use fewer nodes to achieve consensus in les time. However, this makes the chain more vulnerable and centralized. It is easier to corrupt or destroy 10 nodes rather than 10, all over the globe. Although often discussed as such, blockchain scalability does not just pertain to TPS. L1s must be able to process more transactions without creating more problems down the road. A node in a technically sustainable blockchain has to do three things:.
These are bottlenecks for every node which means there are upper, finite limits to how far you can push the network. But larger, more expensive, and fewer computers in the network like Solana is clearly a form of centralization. Fewer computers in the network also creates security issues. A hacker attacking just a few computers, or a single central computer will have an easier time than attacking a huge number of computers all in agreement about the data they are using and creating.
Just as with Bitcoin, more computers participating in the Ethereum network enhance the security and permanence of the data on the Ethereum blockchain. This is slated to occur in Q2 and bring with it many benefits that were not previously possible with PoW.
PoS removes the energy consumption often cited in the mainstream media. Without the need for so much physical mining hardware and infrastructure, Ethereum can become a more energy-efficient, geographically-distributed, and nimble blockchain. It is designed, ultimately, for a simpler, more robust, stable, and secure base layer protocol with full lite client verifiability.
The Beacon Chain serves as the epicenter of the future architecture and network consensus. PoS aims to lower the cost of participating in securing the network by allowing anyone with ETH to stake rather than needing a giant million-dollar mining farm as is the case in most PoW networks. A validator is a person or entity who locks up stakes 32 ETH in order to run a validating node and secure the Ethereum blockchain.
With PoS and staking rewards, ETH becomes a productive capital asset with yield as well as a the money underpinning network transactions and executing smart contracts. The Beacon Chain will be responsible for the liveness, veracity, and consensus on the new chain.
Future sharded layers shards will all connect back to the Beacon Chain with many validators across all 64 shards. The Beacon Chain will provide the foundation for hundreds of thousands of validators, distributed across thousands of nodes globally.
It will organize validators into committees and apply the consensus rules that dictate the network. A slot is when a block is added to the Beacon chain. Every 12 seconds there is a slot and 32 slots 6. Casper FFG decides on which blocks become part of the chain, finalizing an epoch. Every epoch, one validator is pseudo-randomly assigned by a beacon to a slot and shard. At least one committee, a group of validators minimum of is also chosen to attest the epoch. Additionally, PoS is a predecessor for sharding, another critical Ethereum protocol change that will separate the chain into many concurrent threads discussed more below.
Sharding is the term for horizontally partitioning a database and does not create more burden for the average user. In this sharding model, validators are assigned to specific shards and only process and validate transactions in that shard. In Ethereum's planned sharding model, validators are randomly selected. Just like the Merge, the sharding plan has evolved over time and may continue to change between now and implementation.
Sharding is the partitioning of a database or blockchain into subsections. Rather than building layers atop one another e. Doing so does not create more burden for the average user. Shards will be divided among nodes so that every individual node is doing less work. But collectively, all of the necessary work is getting done—and more quickly. More than one node will process each individual data unit, but no single node has to process all of the data anymore.
This means they are only responsible for processing and validating transactions in those specific shards, not the entirety of the network. However, now with rollups providing the much-needed network scalability, sharding will focus on data availability to provide throughput for the rollups.
This is because the bottleneck for rollup scalability is data availability capacity rather than execution capacity. This enables tremendous scalability gains on the rollup execution layer. Just as significant, shards will also help avoid putting overly-onerous demand on full nodes, allowing the network to maintain decentralization. Sharding will be released in a multi-step process to provide immediate data availability for rollups before releasing the ultimate but more complex vision.
A small subset of data shards four will initially be released to keep complexity low, i. Earlier, we outlined one reason why Ethereum transaction fees were so high was due to all nodes in the network having to process all transactions and reach consensus.
Shard 1 could process one batch of transactions, while Shard B processes another batch. This would effectively double the transaction throughput of a blockchain, since our limit is now what can be processed by two nodes at the same time. If we can split a blockchain into many different sections, then we can increase the throughput of a blockchain by many multiples. Ethereum will be split into different shards, each one independently processing transactions. There are several different ways a user can stake ETH.
The most autonomous and preferred method is to personally run a staking node. However, this requires at least 32 ETH plus some intermediate technical knowledge around the protocol, nodes, and computer hardware. Another option is staking on centralized exchanges like Coinbase, Binance, Kraken, and others. These exchanges take custody of your ETH, stake them on the user's behalf, and take a cut of the profit. This abstracts away the difficulties of running your own validator but comes with the tradeoff of giving up custody and some of the profits.
The top four staking entities include traditional centralized exchanges Kraken and Binance, liquid staking protocol Lido, and Staked. Decentralized solutions like Lido and Rocket Pool, which enables "liquid" staking are gaining traction. This gives stakers more flexibility and liquidity since they can sell their stETH tokens on the open market or use the stETH tokens in other DeFi protocols.
Staking derivatives are the most efficient route for holders of PoS tokens that want to maximize yields and utility in DeFi. The base fee is set by the protocol and adjusts every block based on network activity. The base fee no longer goes to miners but is instead burned. The tip is set by the market can be zero in times of little congestion and will go to the miners. All of these big changes are being made in an effort to provide increased scalability for the Ethereum chain which, since , has regularly experienced periods of congestion and high network fees.
The Merge, although important, is just one step in an enormous transformation for Ethereum. This traditional monolithic, do-it-all blockchain faces unavoidable limitations due to the inefficient nature of decentralized consensus. These limitations lead to higher transaction costs for its users as the chain becomes more adopted and used.
Full stop. This is because blocks and blockspace on the execution layer of a chain are scarce. Once demand outstrips this finite resource, the only recourse users have left to ensure their transaction gets into a block and executed is to pay more than the market rate for transaction fees. Side Chains In the context of Ethereum, sidechains are separate, Ethereum-compatible blockchains.
Sidechains can be independent EVM-compatible blockchains, but more likely, they are application-specific blockchains catering to Ethereum users and use cases like Polygon or Ronin. Sidechains design themselves to be EVM-compatible so they can essentially copy and paste their code to easily interoperate with Ethereum and all of its infrastructure including wallets, block explorers, and more.
It could be that my question is a bit broad one, but I just can't split it into separate questions as the concepts are so tangled together! In a simplified manner, this is how a blockchain looks like I will have some ideas referencing this below :. Let's say we have a smart contract that stores a list of node addresses.
Each time a node triggers the contract's iWasHere function, the node's address gets to be added in a list and one can read the list of addresses by calling the whoWasHere function. I would like to have a more in-depth understanding on what exactly means for a smart contract to be ran on a blockchain and what happens exactly under-the-hood. Is it attached, to a block, on a newly mined block, e. How does one access that contract, then?
You just scan the whole chain for smart contracts with a certain contract address? The EVM byte code corresponding to the code that needs to be executed by that function call gets added to a transaction and then recorded on the block? Who does the code execution per-se i. If all the nodes in the network will run the code, how is this scalable? What happens when there are Isn't the same as Can someone explain or point me to some documentation that explains these concepts?
The web is full of high-level explanations on how does the system works, but couldn't find anything on the low technical level. For starters let's not equate smart contracts with people, that's a very OOP idea and it just confuses the entire issue, in my opinion. I definitely agree that technical documentation and teaching material like this are very lacking. You often get very surface level information.
A smart contract is a passive static thing. You call it to do something and it will do the thing. It never does things on its own. It may respond differently depending how much time has passed or blockheight or similar. Or depending on the state of other smart contracts, which it may enquire, as part of your request. Basically a blockchain is just a immutable database that lives "on the internet" decentralized with no single location. And in case of smart contract chains it can also have code.
It is! Everything is blocks, so everything on the chain is on the blocks. I think a contract might be split between blocks, technically, since there is a block size limited, not sure though. Upon deployment, which is an EVM action performed with an existing ethereum address, which costs gas, you receive an address.
That address is where you find the smart contract. Similar to a hashmap, access is very fast. There are two types of function calls in solidity on ethereum "view" types and normal ones. Normal ones do. The gas cost is equivalent to the amount and cost of EVM instructions needed to completely the entire call.
So its only recorded for when you actually write to the chain, not when you just red out a variable, for instance. Do note that for some view calls, some processing is still needed, like going through a loop lets say, and it does in fact not cost any gas to do this.
This is relevant to the next point. So first of all, the way these blockchains are designed is: you run a node yourself and you use it to communicate with the chain. In reality most people use a third party, lets say metamask or infura or others. But these third parties just run nodes themselves and give you the answer you are looking for, they must still run a node like you can do yourself.
These services usually cache all blockchain data in a faster and more convenient database. When doing a call that writes, a miner has to actually mine it. Mine the block, attach your stuff to the block, execute code if there is any and write the result to block. This is where it does get foggy for me: The consensus mechanism ensures data is correct and by more nodes picking up the blocks you produced, it becomes accepted. But it is only written once. This goes into the territory of knowledge proofs for example if you want to look further into it.
But you do only write once, a miner does it. After that via consensus we determine, via consensus algorithm, that this write was correct and you didn't trick the system. One could write an entire book answering all the questions you've lined up, but let me take a stab at 50, feet:. Contracts aren't attached to the blockchain, they ARE part of the blockchain, as in, the code is inside the block itself. This is the part that is mined, that way you know it's not tacked on later by a malicious party.
Contracts are indeed passive entities. They just sit there unless someone tries to use a function that write to the blockchain. Each node also known "a miner" does run every contract at once, essentially. The reason this is scalable in an initially unintuitive way is that no one can fake the results of a computation without pretty much every other node saying "NO WAY", so those results get discarded.
If you want real low level descriptions of how it works, you'll probably have to crack open some code and start trying things yourself!
