Decentralized networks can only provide 2 out of 3 benefits at any given time in terms of decentralization, security, & scalability Blockchain Trilemma
Let’s look at modular blockchains which aim at solving for scalability & flexibility
We’ll be comparing different modular blockchains today, but first
What’s modular blockchain?🧐
In monolithic blockchains such as bitcoin,Ethereum all the nodes & validators of the network are required to execute the same txns & do consensus on the chain
Modular blockchain..
..focuses on handling a select few duties (consensus, execution, Data availability & settlement) & outsourcing the rest to one or more separate layers
It’s just like separating a system into distinct components that can be combined in various ways to achieve specific objectives
Think of it as Lego bricks that can be combined to form different structures 🤯
Now that we understand the concept, let’s look at different modular blockhains:
Ethereum’s adoption of sharding and rollup-centric computation does make it a modular chain.
👇👇
In sharding: It separates consensus and data availability, which splits up the blockchain into multiple sub-chains, each handling a different portion of network activity.
Ethereum is adopting a sharded design in which 64 shard chains will operate in parallel
👇👇
In rollups: It outsources execution while focusing on settlement, consensus, and data availability.
Ethereum acts as the base layer (L1) for rollups sitting on Layer 2
@0xPolygonAvail
In this network, nodes are only responsible for storing and ordering transactions, they don't interpret transaction data for execution. These chains serve as data availability layers for other execution layers (e.g., rollups)
Any execution environment can use..
..Avail for data ordering and availability be it off-chain solutions or standalone solutions
@CelestiaOrg is another modular blockchain that specializes in consensus and data availability, off-loading execution to separate chains, such as rollups
Decoupling execution from other functions, alleviates the largest bottlenecks associated with a monolithic chain from the base layer:
transaction execution & state bloat👀💯
Validiums
They use off-chain data availability & computation to improve throughput by processing txns off the parent chain. Like ZK-rollups, validiums publish zero-knowledge proofs to verify off-chain txns on parent chain
This prevents invalid state transitions & enhances the..
..security guarantees of a validium chain
These validity proofs can come in the form of
ZK-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) or
ZK-STARKs (Zero-Knowledge Scalable Transparent ARgument of Knowledge)
More on this in tomorrow’s thread👀👀
Rollups are an example of modular blockchain
More on rollups here
Whether its a brand fight b/w Pepsi & Coca Cola or Nike launching a new shoe collection, brands spend millions of $$ on marketing to win the battle. For brands to hold a prominent position in the eyes of their targeted audience, strategising is vital
Let me ask you question👇👇
How much does an Umbrella cost?
10$ - 12$ maybe
What's the function of an umbrella?
📌To Keep you dry when its raining
There’s a brand called Pasotti, whos’ umbrellas cost anywhere between 250$ - 800$
Obviously a more sturdy, luxurious umbrella, even opening it sounds good💯
But, why would someone pay 500$ for an umbrella when the function is the same?🤔
When people are buying quality, they’re expecting something different. They take better care of it, and since they take better care of it, it lasts longer.
Its finally day 26 of #web3glossary🚀
And with this, series has come to an end
Z: zk Rollups
By learning you'll teach and by teaching you’ll learn. Sharing on web3 terms & jargons for the last 1 month was a great learning experience for me and I hope for you too
Let's get to the thread now?
Having to spend $20 or more in gas fees for a single txn is not ideal if you want to complete a DeFi trade
If you've been hearing zk or zero knowledge, you're not alone. It's the next big thing in web3
With an increase in the number of Dapps, ...
there’s a need for faster processing speeds & cheaper txns.
That’s when layer 2 solutions came in.
Zk rollups are also a layer 2 scaling solution that increases throughput on Ethereum Mainnet by moving computation & state-storage off-chain
Consensus mechanisms ensure that all the txns on the network are genuine & all participants agree on a consensus on the status of the ledger. PoS and PoW are the most commonly known.
Today we look at PoA, PoB, PoC and PoH
👇👇
Need some background on consensus algos? Check out this thread on PoS vs PoW
Both PoS and PoW have their fair share of pros and cons, let's look at how other cosensus algos differ
PoA: Proof of Activity (not authority)
To verify participants blocks, it combines its tokens to allow both mining and staking. The blocks themselves do not contain transactions

Do you remember the first time you heard about Blockchain? Maybe you took it as a new technology that would change everything. Maybe you just wondered if you should start investing in crypto.
Maybe...
👀👇
..you were just getting your head around the concept of a decentralized web
The truth is web3 is indeed the decentralized internet of the future🚀
#web3glossary was started as a series of twitter threads to help people understand this space better and clear the air around...
.. the terms & jargons we hear around. We are almost at the end of the series and I would like to hear from you what value you gained from it and what more would you like to see😃
Until then, let’s get to today’s thread
Let’s go back to where it all started- the world wide web👇
Validators of blockchain technology aren't only its sower but its rewards reaper too. Let's get to the depth of it🧐
But first, here's some humor to start with
👇👇
What are crypto validators and how do they work?
Crypto validators = Payment processors of the decentralized networks.
Technically, a crypto validator is a participant in a blockchain responsible for verifying txns.
After verifying the legitimacy of the txn, the validator adds..
..it to the distributed ledger.
Seems like the job of a blockchain validator is not that difficult!
You receive some data, check its accuracy, and validate it or not.
However, on a distributed ledger, it's easier said than done👀👀
Grab your coffee, coz it's a slightly longer thread today 😅

Web 3 is redefining how we communicate and share information. While developers are busy building the infrastructure of web3, the
user experience of most dApps has taken a back seat.
With over 4.95 billion, daily active online users spending a fair share of their day on the web, most people have not heard of of dApps or the blockchain technology that powers them.
A small percentage of those who have, often find it difficult and complex to use.
