Ah the good ol "$0 fee" FUD

This is a magnet for people who can't conceive of a standard growth playbook in startups: subsidize costs, grow market share, monetize later.

Celestia's fees are currently set to ~$0.00001 per user tx, 50x less than Ethereum blobs and 100x less than Solana. The reason it's not exactly $0 is for spam prevention. We don't care if we don't make revenue in the short term - it's peanuts compared to where we're going and we want to win in the long term.

And the strategy is working as intended. Market share has steadily grown since launch, we have a rapidly expanding ecosystem with top apps like Abstract, Converge + Ethereal by Ethena & Securitize, Blackbird, and Noble launching soon to name a few. $600m in TVS will soon become billions. 25 chains will soon be 50.

The time to be bearish was before we had clear PMF and one of the strongest app ecosystems of any L1.

Data Availability ≠ Data Storage

What's the difference?
🥫 Data storage is like canned food
🍱 Data availability is an all-you-can-eat buffet

Thread 🧵 Image
Data storage is a solution to the problem of needing to save data so that you can retrieve it later.

This is like canning food. You jar it up and store it away so that it is preserved to be eaten later.
Data availability is a solution to the problem of needing to make data available for anyone on the internet to download.

This is like an all-you-can-eat buffet. You want to put all the food out for anyone to come and eat as much as they want.

Had a realization that staking might not be as secure as we think 😬

Please someone tell me why I'm wrong 🧵 Image
TL;DR, when you slash a validator they don't lose their delegated stake, only their self-stake which is often much smaller.

So a rational validator will misbehave for a much smaller reward than the total stake, which makes economic security lower in practice.
Longer version:

In proof of stake chains, slashing prevents validators from doing bad things like:
1. re-orging the chain
2. commiting fraud

A smart contract rollup is a state within a country.

A sovereign rollup is its own country. Image
A state can have its own laws, but it answers to a higher power - the federal government.

A country answers only to itself. Image
As always, neither is necessarily better than the other, they simply have different tradeoffs.

Celestia supports both.

Is a rollup on @ethereum more secure than a rollup on @CelestiaOrg?

Yes and no.

Here are the tradeoffs and why security isn't what you think 🧵 Image
To understand why rollups on Ethereum aren't necessarily more secure than on Celestia, we need to define "security".

There are two aspects of security:
⛓️ Immutability
✔️ Verifiability

Let's unpack them
⛓️ Immutability is how hard it is to re-org a chain.

The more expensive it is to re-org the chain, the more secure the chain is against a double spend or similar attack.

For all my DA nerds out there, @musalbas wrote a forum post that classifies the security of different data availability schemes into 7 levels.

Quick tl;dr 🧵 Image
Level -1: Full Node

Best possible security. Downloads all the data directly, ensuring it's available without any security assumptions.
Level 0: no DA guarantees

Worst possible security. Don't do anything to ensure that the data is available. Fine for use cases that don't require DA for safety, like NFTs

Example: IPFS

"While the world computer has been a tremendous success ... it has strumled upon two main limitations in recent years; sovereignty and scalability.

We think modular blockchain networks envisioned by Celestia is the right path forward to overcome these limitations." 🔥
Why Sovereignty 🔥

"Blockchains are social coordination mechanisms ... unlike human-consensus, which is slow, unordered & abstract, [blockchains are] precise, fast & deterministic.

This power is useful to the extent that it represents intentions & values of the participants."
