I'll never forget what my Ph.D. advisor Bob Gallager once said:
"Many people think research is about discovering new knowledge. But the main job of research REALLY is pruning the knowledge tree."
Here's what he meant, and how I apply it to Blockchain:

The city of Babylon is one of the first marketplaces in the history of mankind.
Our startup, Babylon, is that for blockchain.
It's a two-sided marketplace where on one side, Bitcoin provides security. On the other, chains consume that security.
We're the modern Babylon.

Learning mathematics is just as important as learning English, French, or Spanish.
Math is its own language. It is a language by which we understand the world around us.
Not knowing math - or being scared of math - is like being illiterate

Very passionate about sharing
#Bitcoin
security so quite excited to see this new development.
Question: If rollups can share the full security of the most secured chain in the world, is there still any need to use sovereign chains like Cosmos SDK chains?
You can now run a sovereign rollup on Bitcoin.

In short, a sovereign PoS chain timestamping on Bitcoin can combine the short range PoS security and long range BT security with small footprint on Bitcoin. A rollup on Bitcoin is only secure if full data is on Bitcoin.

@VitalikButerin
"dual-use of validator staked ETH, while it has some risks, is fundamentally fine.": wouldn't any dual-use reduce the security margin of Ethereum? Attacking Ethereum now becomes more profitable because the same attack cost can pay for attacking both Ethereum and the other use?

I am bullish on the mesh architecture where each chain can share security with neighboring chains. But I think there are multiple ways to implement this sharing. Cross staking a la

In this paper (with

I still remember the first time I learned what a mathematical limit was.
At first, it seemed like the opposite of infinity. But they're more like twins.
When you take the limit of something, you're dealing with the infinitesimally small.
The limit is the core of calculus.

In web3, security is of utmost importance. Why?
It's not run by a central bank, or someone big like Facebook or Google.
It's run by decentralized agents. Some may be malicious.
At Babylon, we take the security of Bitcoin and allow it to benefit the rest of web3.

Great that you bring up this important point. Indeed as we discussed before, we found it rather surprising that no one had really used ibc for sharing security. This is a core idea underneath
@babylon_chain
that we can use IBC to share security to other cosmos zones
the idea is to bootstrap a view of the Cosmos Hub via a checkpoint hash (longer duration), and then use the Hub’s view of the target chain to bootstrap a light client for it

It is well known that one can tradeoff safety and liveness by tuning the quorum threshold in a BFT protocol. What we showed in this paper is the surprising result that one can design protocols that can *simultaneously* achieve *all* tradeoff points. Come to the talk!

And it's a core component of how we approach blockchain at our Stanford research lab.
In blockchains, there are MANY new projects with MANY layers.
Ethereum, Polkadot, Avalanche. And on and on.
With that many protocols proliferating, it gets complicated.

PoS vs PoW, additional attack vectors in PoS,which are fundamental which are solvable, longest chain vs BFT, all these are central to PoS Eth design. Lots of research done and good time to talk about them now with the Merge.

If you are trying to build a new blockchain, you start to wonder: which one should I use? Or if I'm creating a new one, what should be my basis?
This proliferation of technology is actually not the best thing for the field.

Yes totally agree. We recently discovered a new trustless use case for bitcoins: staking to secure PoS chains.

But even at the max 4MB blocks, Bitcoin's throughput is only 53 kbits per second! This puts a severe limitation to the thruput of the rollup, as well to scaling the solution to many rollups.

Well said. App chains that serve other app chains .
My thesis is that the only viable business model in the interchain is to make something other chains want.

Good summary. Since our lab worked hard with Eth Foundation on this problem, I feel pained but compelled to add that there is currently NO security proof for PoS Ethereum. This is below the standards of 40 years of consensus research.

Because the validators are running a fast PoS confirmation process, most transactions can be confirmed fast. Confirmation of high-valued transactions can wait until obtaining a timestamp on the BTC chain.
