As predicted, now that the summer is officially over the pace of whitepapers is picking up! Here are four new additions to the #CryptoArchives:
0/8
github.com/multicoincapit…
First, @LefKok, @dahlia_malkhi, @ittaia and Sasha Spiegelmann implemented a fully asynchronous DKG based on a novel "eventually perfect" common coin abstraction. 1/8

eprint.iacr.org/2019/1015.pdf
It's amazing how many new DKG constructions have come out in 2019. You'll find them in our Cryptographic Primitives -> Other section:
2/8
github.com/multicoincapit…
Second, @danrobinson produced The Yield Protocol. His yToken construction allows users to mint and trade synthetic fixed term assets. The market discount applied to these yTokens can infer "interest rates", from which a yield curve can be constructed. 3/8

research.paradigm.xyz/Yield.pdf
I placed this in our Cryptoeconomics -> Tokenomics section... but should I have a standalone DeFi section? What additional papers would you recommend adding, if I were to do so?
4/8
github.com/multicoincapit…
Third, @SaarTochner, @Avivz78 and @schmiste78 released "Hijacking Routes in Payment Channel Networks" describing how a Denial-of-Service attack on Lightning Network nodes could be used to disrupt payments.
5/8
arxiv.org/pdf/1909.06890…
This paper, of course, goes in my largest and favorite section: Vulnerabilities, Bugs, and Hacks -> Attack Vectors. I am constantly amazed by the range of different attacks the community comes up with, am I missing your favorite one?
6/8
github.com/multicoincapit…
Last, but certainly not least, is Halo from @ebfull, @str4d, and @feministPLT. This Recursive Proof Composition without a Trusted Setup can be used to greatly reduce blockchain storage requirements, and to increase the trust-minimization of zk-SNARKs.
7/8
eprint.iacr.org/2019/1021.pdf
As always, please feel free to reach out if you know of a paper or a blog post that should be included! The #CryptoArchives is meant to belong to the community, we accept pull requests from any and all contributors.
8/8

Apropos of nothing, here's a thread of recently published research focused on #bitcoin and Lightning.

I don't know if these researchers submitted their work to the Science of Blockchain Conference (SBC), or if SBC denied their applications. But it's clear they're researching!
"zk-PCN: A Privacy-Preserving Payment Channel
Network Using zk-SNARKs"

Published Aug 20, 2022 by researchers from Shandong University, Indiana University, Purdue University, and the Singapore University of Technology and Design
arxiv.org/abs/2208.09716
"Revoke and Update: A More Flexible Payment Protocol for Payment Channel Networks"

Published Aug 15, 2022 by researchers from the Delft University of Technology

On platform risk:

Smart contract platforms have seemingly found PMF with DeFi over the last year. App devs are flocking to said platforms in hopes of launching the next COMP, UNI, SNX, etc. and cashing out life-changing money after a few months of work.

Too good to be true? 🧵
The canonical platform risk case study is Facebook vs. Zynga. Zynga built a $10B company on Facebook's platform, until March 2011 when Facebook cut off Zynga's access to their APIs and cratered their business.
venturebeat.com/2016/06/30/fac…
Ethereum's narrative from 2014-2018 was that it existed to fix this problem.

A "world computer" running "unstoppable code" where nobody could pull the rug out from under you like Facebook did to Zynga.

Inspiring stuff! Have they lived up to it?

I've had a lot of people reach out recently and ask what's been driving the #LightningNetwork's latest exponential growth phase.

I think I'd attribute it to four main sources:
🧵👇
1) The combo of @getumbrel, @RaspiBlitz, and @voltage_cloud with the host of node & liquidity management guides produced by @LeoAW and @hmichellerose have made it stupid easy to get a node online and connected.
docs.lightning.engineering
This laid the groundwork for some super vibrant communities of node runners to pop up a la Ring of Fire and Plebnet. These groups are the primordial soup out of which the next wave of LN startups will emerge IMO... lots of tinkering and lots of great memes

Recently, I've been thinking about this chart from @hasufl and @nic__carter concerning the changing #bitcoin narrative. I think the recent focus on NgU has been misguided, and we've lost sight of the true common thread tying all of these together:

#Bitcoin is freedom money.
One thing I've learned from watching DeFi over the last year is that NgU tech is not unique to #bitcoin. Supply side liquidity crunches can be programmed in a few lines of Solidity.

But true monetary freedom cannot. #Bitcoin is the money chosen by people seeking to be free.
As the FUD machines spin up and market dominance wanes, I think this is very important for us to internalize. #Bitcoin guarantees its adopters that they will be free. Being free does not guarantee being rich. And if freedom is not continually fought for, it will disappear.

So I have a lot of thoughts about this. History is definitely rhyming as we build the Internet of Value today in a similar manner to how the Internet of Communications was built from the 1970s to now. But many people are applying the wrong lessons from the past to the present!
Email (SMTP) was invented in 1982, and was the Internet's (TCP/IP) killer app for 30+ years and arguably still is. When @ChairmanHeath says "Internet" he's prob referring to HTTP, invented in 1989 by Tim Berners-Lee and popularized by the browser, the Internet's second killer app
I can't remember where I got this screenshot, apologies, but it perfectly distills what HTTP brought to the table: more media types beyond text!

Similarly, Bitcoin only transfers BTC, while Ethereum allows for many types of "value" transfer. Pattern matching to HTTP isn't crazy.

So now that we all agree that globally available blockspace is not scalable for actual computation, but is best used for verification of off-chain computation instead, here are some thoughts on Ethereum's approach to scaling vs. Bitcoin's.

~👇~Thread~👇~
First, definitions:
1) broadcast txs: all-to-all gossip comms that succumbs to the scalability trilemma (all L1s)
2) unicast txs: 1-to-1 direct comms that occurs between two peers only (LN)
3) multicast txs: 1-to-many comms between a subset of peers (rollups, sidechains)
Both Bitcoin and Ethereum's L1 use broadcast txs. But because of (IMO) Bitcoin's use of UTXOs vs. Ethereum's use of accounts, Bitcoin has prioritized unicast txs via LN first, whereas Ethereum's initial unicast txs projects have been discarded in favor of multicast txs.
