Launching the new Celestia “Mamaki” testnet and introducing the Alpha Data Availability API! 🍵🧵 blog.celestia.org/celestia-testn…
Today, we are excited to announce the launch of the new Celestia “Mamaki” testnet! This marks the next step towards mainnet - a modular blockchain network that enables anyone to easily deploy their own blockchain without the overhead of bootstrapping a new consensus network. 🧱

How do modular blockchains bring scalable shared security to the @Cosmos?
CTO @KreuzUQuer took the stage at @Gateway_Conf to explain and outline the modular design 🧵 🧱 @cosmos@KreuzUQuer@Gateway_Conf Right now, there is a problem with current blockchains. The process of 1) checking if a block has consensus then 2) verifying if all the transactions are valid is inefficient. We face a bottleneck.

Rollups have emerged as the dominant choice for execution in the modular paradigm. While they have desirable security properties, in what ways are they scalable? Here’s a brief look 🧵
To recap, a rollup executes transactions and builds blocks which are then published to a different blockchain, which we’ll call our base layer. The base layer will at minimum, provide consensus over the transactions and ensure they are available.

By decoupling consensus from execution, Celestia also removes settlement functionality. What happens to rollups that need settlement, and what are the advantages of a separate settlement layer?
Let’s take a look 🧵
The purpose of removing settlement from Celestia is to reduce the burden of execution and smart contracts, such as state bloat and congestion. However, rollups that want better interoperability or a separate dispute resolution layer need a settlement layer.

To us, blockchains are more than a technological advancement. They are a mechanism that enables individuals to coordinate in a sovereign manner. To guide this vision, here is an overview of the values held by modular blockchains 👇🧵
1. Users are first class citizens of the network
Technologies like fraud/validity proofs and data availability enable users to be first class citizens. They can verify the network with equivalent security to full nodes but with significantly lower hardware.

It is clear that the transition to a multi-chain ecosystem has emerged. The question remains, what will that ecosystem look like in the future?
Here’s the TLDR on our vision 👇
We believe modular blockchains are the natural progression of a multi-chain ecosystem. Instead of blockchains that do everything, the core functions are separated across multiple specialized layers.

Modular blockchains split the processes of a single monolithic blockchain into multiple specialized layers. What exactly are the benefits of taking this approach?
Let’s take a brief look 🧵👇
Execution layers, such as rollups, can harness a modular architecture without sacrificing sovereignty. A sovereign rollup has the ability to push upgrades and fork without permission from any underlying layers, just like an L1.

The final layer we’ll be looking at in the modular stack is the consensus and data availability layer.
What do those terms mean and how does a blockchain work without smart contracts? Let’s take a look 🧵👇
What does a consensus and data availability layer like Celestia do?
To provide consensus, validators order and agree on transactions to ensure we know which one came first. Unlike most blockchains, the validators aren’t concerned if the transactions are valid or not.

What is an execution layer?
As modularity allows the key functions of a blockchain to be separated across multiple specialized layers, the terms L1 and L2 make less sense.
We need new terms that provide clarity for the modular paradigm.
Let’s begin with execution layers 🧵
An execution layer is simply a blockchain that specializes in providing an environment for applications to live and processing transactions that interact with those applications.
It doesn’t do consensus or data availability… just like a rollup!

Recently, @jadler0 spoke with @CannnGurel on @Delphi_Digital to chat about the future of blockchains. The future is modular. Here are some important takeaways: 🧵
.@CannnGurel: "Celestia is a project that I’ve been following for a while now. In my own opinion, I see it as the most beautiful thing since Bitcoin and @ethereum."

Celestia serving as off-chain DA for Ethereum rollups 🧵
The main reliance that rollups have on L1 is the cost of calldata and its data throughput. While Ethereum is in the process of implementing its sharding solution, rollups should have a source of cheap data…
and high data throughput to alleviate some of their near-term scaling bottlenecks. While transaction fees can become cheaper when amortized among a larger batch, there is a point at which the fee decline reaches diminishing returns.
Yesterday, @jadler0 took the stage at @ethereumDenver to talk about "Secure Off-chain Data Availability for Rollups".
Miss it? Below are some key highlights: 🧵
"A monolithic blockchain, in its base consensus layer, does data availability, settlement and execution, and usually settlement and execution are tied together."

Sovereignty and communication between chains 🧵
Blockchains that are sovereign have freedom to choose their preferred execution environment. A sovereign blockchain on Celestia has no restrictions imposed on it, giving it the ability to upgrade or fork if necessary.
Ultimately a sovereign chain can make changes in accordance with its own social consensus, independent of Celestia or any other chain.
As such, these blockchains on Celestia are flexible in design possibilities. They can be composable shared environments for many applications…

The Celestia Labs team is excited to introduce Celestiums, which are Ethereum L2 chains that use Celestia for data availability (DA) and Ethereum for settlement and dispute resolution. Read more: blog.celestia.org/celestiums/
Celestiums have a higher threshold of security than previous off-chain DA solutions by adopting a PoS validator set, and will allow for better data availability throughput.
At the core of a Celestium is the Quantum Gravity Bridge, a Celestia to Ethereum data availability bridge.

The benefits of modular blockchains 🧵
Modular blockchains are the result of separating the core components of a single blockchain and running them on separate layers.
Here’s what makes them powerful 👇
Layers that specialize on a couple of core components allows for greater scalability innovations without the burden of making tradeoffs that come with a modular blockchain. For example, a modular DA layer with DA sampling can scale linearly with the number of users.

Blockchain bootstrapping costs 🧵
While the ease at which new blockchains can be created and deployed has improved over time, there are hurdles and costs associated with doing so. Currently, an independent blockchain can be created using a template, but the difficulty comes...
from the requirement to launch a new coin with a large distribution and find validators to help bootstrap the network. This process is time-consuming and can become considerably expensive.
Celestia provides a minimal base layer that makes it simple to develop blockchains…

Rollups on Celestia 🧵
Celestia does not support smart contract capabilities because it is designed to provide data and consensus for rollups, which will support them.
One advantage is that rollups will be able to explore new novel designs for settling proofs.
One approach is for rollups to distribute proofs directly on the p2p network.
In this case proofs aren’t posted on any settlement layer, they are verified locally by clients of the rollup. This is similar to how @MinaProtocol works.
