There’s multiple things to slice-and-dice here…

By default, a lot of CeFi (and as seen with @dYdX, some DeFi protocols) default to “traditional KYC” because, let’s be honest, the developer experience to integrate a check from Onfido etc is far easier and well understood.
However, the *user* experience of traditional “selfie-scan-check” KYC is universally bad.

Nobody wakes up and is excited about “Ahhhhh, today’s the day I’ll go through another KYC process 🌞”
And so almost inevitably, the DeFi space “hates KYC” because this is precisely the kind of broken process that they dislike from TradFi.

The sad thing is that KYC isn’t even very effective at preventing behaviour like money laundering etc (from @sytaylor sytaylor.substack.com/p/fintech-food…)
To me, the way KYC, liveness checks etc are set up really remind me of the “security theatre” of TSA checkpoints: they are an extremely onerous box-ticking exercise that are very expensive and ineffective at what they are supposed to be doing: theverge.com/c/23311333/tsa…
Which brings me to “is there a better way”…

While “traditional KYC” arguably fails at being effective, what even DeFi projects like @dYdX need is a way to understand ✨ reputation ✨ of users.

Are they Sybil attacking the tokenomics? Are they pretending to be someone else?
Even DeFi maximalists who don’t want to replicate traditional finance techniques will likely get on a Zoom call or otherwise to try and ascertain whether they are interacting with the right person/wallet before a high value transfer.
So, more relevant for DeFi could be “Am I transacting with the right person with THAT @BoredApeYC profile in their Twitter handle?” as a form of “KYC”, rather than traditional KYC.
Except…the only way people *think* they can solve this is by falling back to selfie-scan-check.

There are better, more privacy-preserving ways of doing what I described above. You could call it #Web5, or you could call it what we’re building @cheqd_io 🤓

This is a *really* good thread rounding up #Web3 identity and privacy tech companies. Wanted to throw in a few more on the list that IMO deserve a mention...

@AnonyomeLabs, which is working on a wide-ranging super-toolkit that covers phone, email, passwords, credentials
@Avast, one of the world's largest cybersecurity companies that now owns @evernym and @SecureKey (and is likely to be a powerhouse in wide-ranging existing user base)
@darrello from Continuum Loop (no Twitter?) for niche consulting and expertise in digital identity

🚨 We built a network-wide validator status monitoring tool for @Cosmos SDK chains that can monitor for validators that have missed too many blocks, and are likely to get jailed.

Check out the code on @cheqd_io's GitHub 👉 github.com/cheqd/validato…

Here's how we went about it...
1. To provide some context here: proof-of-stake blockchains like @cosmos use a self-reinforcing mechanism to ensure nodes maintain good uptime.

You can see this on our block explorer: explorer.cheqd.io/validators
2. We decided to build this because a few node operators have been jailed in the past for missing too many blocks. As a reminder, validators on Cosmos SDK networks get slashed if they miss too many blocks within a defined window. learn.cheqd.io/overview/intro…

I looked into *why* the supply of Covid-19 rapid tests has been so badly disrupted in the UK.

TL;DR: All of the distribution is being handled by a single company which will be closed for 7-8+ days around Christmas and New Years' Eve and therefore shortages will persist.

🧵👇🏾
Distributions only resumed on 29th Dec and will be closed again 1-3 Jan (1-4 Jan in some UK countries).

Overall, there's only approx. 1.25mn Covid LFD test packs that will even be processed at the distributor. (There are ~27.8mn households in the UK.)

All of the distribution for Covid lateral flow test kits is being handled by a company called Alliance Healthcare along with its logistics arm Alloga UK.

Here are the list of holidays/closures it announced on 1st December across England/Wales, Scotland, NI. ImageImageImage

Out of London for the first time in a year or so, on a short trip to France.

I was able to scan my Covid-19 vaccine record from the NHS App into the French “TousAntiCovid” app.

Much like the UK, there are two modes: one for domestic use, and one for travel.
In general, the QR codes in vaccine passports generated in Europe contain name, DOB, date of jab, kind of vaccine etc. This is an EU-wide standard also used within the NHS app. github.com/nhsx/covid-pas…
When I scan the NHS code into the French TousAntiCovid (“everyone against Covid”) app, it has two modes: one for domestic use in France that visually displays only the QR code and name. This is for showing in restaurants, bars, etc.
