If you want to understand how Umbra keeps you private on-chain, and why this matters for what we’re building:

1. Funds enter a shielded pool
You create a private UTXO that locks tokens in a Merkle tree. From this moment, your funds are mixed with everyone else in the pool.

2. The sender and withdrawer are separated
The sender locks the funds. The unlocker later withdraws them.
This breaks the usual “deposit → withdraw” link on-chain.

3. Deposits are encrypted on-chain
A ciphertext is published so only the intended recipient can discover the funds -> no public link between sender and receiver.

4. Privacy grows over time
As more users deposit into the pool, your anonymity set increases. More users = harder to trace.

5. Claiming uses zero-knowledge proofs
The receiver proves they own the funds without revealing which deposit was theirs, then burns the nullifier to prevent double spend.

6. Withdraw privately by default
Funds can stay encrypted, meaning:
No visible destination.
No visible amount.
No visible link to the original deposit.

Umbra makes private transfers programmable infrastructure.

This is exactly the primitive we’re excited about at Chamber (@chamber_vault ), bringing privacy-first treasury and payments to real teams.

Some Nigerians are angry at this book by Carlos Barragan, as if they did not spend decades glorifying internet fraud in their songs, movies, cultures and communities. As if there aren't well known and respected celebrities who are known internet fraudsters. As if these fraudsters don't almost run night life in cities like Lagos. As if the language of internet fraud is not very common among young people in many places. As if Nigerians did not sing gleefully alongside Nkem Owoh when he sang: "419 no be thief, it's just a game, everybody day play am, if anybody fall mugu, my brother I go chop am.... Oyibo man I go chop your dollar, I go take your money disappear...you are the mugu, I am the master."

lol, please define “best life”

I hope you don’t mean partying, drinking and man hopping

the billionaire part is very important, pussy is everywhere

[riskmaxxing @riskmaxxing]

if college didn’t drown you in pussy or connect you with a tech billionaire, you literally got scammed

There's no male version of the "ick" because having to hide your disgust at women's inadequacies is the usual state of affairs for men.

A lot of Ai hate is just performative groupthink

i just generated an image in the style of a Monet painting using AI

please describe, in as much detail as possible, what makes this inferior to a real Monet painting

Funny how we are literally just having this conversation with my guys, right as I opened this app,
Nothing is more important than getting distribution, all your work will literally be in vain if you don’t get this right

[Harri @Harri_obi]

Everybody is building new tools and features. Nobody is trying to solve distribution.

@maleficboss @chamber_vault @Daveoy01 The public vault remains available for transparency-requiring operations... The choice of public vs. private is always yours, on a transaction-by-transaction basis.

@maleficboss @chamber_vault @Daveoy01 damn, just seeing this, it's fixed now

[Avour @Avour5]

this is an interesting perspective, I honestly hadn’t thought about

[Yvonne Kagondu @kagondu_yvonne]

When a Blockchain sets up a base in your region, you have about 2 years to become sustainable.
There are certain expectations that need to be met. The grants that are given are not just free money. There is no such thing as free money.
What does it mean to be self sustainable as a blockchain ecosystem in a region:
- Enough projects being built on the blockchain protocol
- You need to build a community that will consume and pay for the services and gas fees for the projects
- Local investors to invest in the projects

The blockchain protocol would benefit from the consumption of projects from the community. This is why the community is the backbone. The gas fees need to be paid to have an ROI on the funding to the protocol itself.
Remember, the founder of the project wants to make money. The investors want their money to return with profit.
So if there is no money coming from your region then it's not worth the investment.
Now Africa tends to need time, 5 to 6 years approximately. But other regions can find uptake in about 2 years. Also Africa might need more support. i.e Local investors rarely invest in Blockchain projects.
At the end of the day it's all about money. Crypto is very capitalist

hot take: all founders should quit linkedin, and come to X for founder marketing.

welcome to the REAL game

[CHAMBER @chamber_vault]

Web2 companies entering Web3 expect "Privacy as default." On public ledgers, sensitive data like burn rates, vendor costs, and payroll are visible to every competitor.
Chamber provides the "invisible" infra businesses need to operate on-chain without exposing their playbook.

I have been targeted more than 3 times by scammers acting as Investors. Please stay safe out there

[Avour @Avour5]

@Melody544152742 be careful out there bro

[Avour @Avour5]

I was halfway through a live technical interview when I realized I wasn’t being interviewed, I was being targeted. 🧵
I almost got my entire system wiped and my crypto drained.

The recruiters were polished. The project looked legitimate. But 10 minutes in, they made the one request every dev should fear:

"Go ahead and clone the repo, so we can walk through the UI together."

The Intuition I’ve seen enough supply chain attacks to know that a "test task" is the perfect Trojan Horse.

I needed to buy time to audit the code without them knowing I was onto them.

So…… I said, leaning back. "Before we dive in, tell me more about the team's approach to scalability. I'd love to hear how the culture has evolved."

The Social Engineering, as they spent 5 minutes talking about agile workflows and flat hierarchies, I was secretly flying through their file structure.

I nodded along to their stories about Friday happy hours while my cursor was hovering over their backend controllers.

Repo (still live):
https://t.co/COsejcP282

Then, I saw it: userController.ts. The Payload,

I kept on with trying to keep the conversation going.

While they answered, I decoded the C2 URL: 🔗 https://t.co/njRSRhsihm

I pulled the payload. It wasn't just a backdoor; it was a full-scale info-stealer targeting:
⚫️Browser Passwords/Cookies
⚫️Exodus Crypto Wallets
⚫️macOS Keychain access

The Turning Point, At this point, I had a choice. Hang up, or call them out.

I waited for the "recruiter" to finish their sentence about "career growth," then I cleared my throat.

"I have a quick question," I said, my voice dead calm. "How much would you say you guys make from this scam you run”

I watched their video feeds. The "technical lead" froze. The "recruiter" started stammering”

The panic in their eyes was the best feedback I’ve ever received in an interview.

Before they could even come up with a lie, the Zoom window went black. They had terminated the call and deleted their LinkedIn accounts within 30 seconds.

What’s the lesson here. These so called Job Interviews lures are getting incredibly sophisticated. They use professional personas and live calls to bypass your better judgment.

The 20 lines of code that would have ruined my month were hidden in a sea of 5,000 lines of boilerplate.

Audit before you install. Audit before you run.

Stay paranoid. Stay safe.

[Harri @Harri_obi]

@Avour5 Crazy!

[Ohanwe Emmanuel @emmanuel_ohanwe]

Social engineering just took another leap. This now brings alot of skepticism around technical bounties and hackathons that ask devs to clone repos and run dockers
