Ever been stuck for hours while integrating a product? 😫
Well, discover the power of Technical Documentation Audits 🧵
This post will cover:
🔍 What they are
💡 Why you should perform documentation audits as a Technical Writer or Developer Advocate
🛠️ How to perform them

Institutions don't avoid on-chain finance because it's too private. They avoid it because it's too public.
Payroll, treasury, supplier payments, all visible to competitors and anyone with a block explorer.
Sombra makes on-chain finance private enough for real business, on a network like Solana that never closes.

Solana won on speed. Now it wins on privacy.
Solana gave the world fast, cheap, public transactions, but every balance, transfer, and counterparty is on display forever.
Sombra closes that gap. Send privately. Reveal only what you choose, to whom you choose. Keep the speed, drop the audience.
The next era of Solana is private. We're building it.

A $5 wrench attack starts with research: which address is worth the wrench. a transparent chain answers that for free, attackers pick victims off public balances
Inside Sombra, there's nothing to read: no balance, no activity, vaults that can't be linked or added up, so you're never on the list of people worth robbing

The scary part isn't quantum breaking Bitcoin's signatures. It's that "just fork it" is not a plan when the coins that need upgrading belong to people who can't sign anymore.
Great lecture from Boneh on what the actual migration looks like from other blockchains.
Can a sufficiently powerful quantum computer forge the signatures used to authorize Bitcoin and Ethereum transactions? What would it take to upgrade both networks before that happens?
In this new lecture, Stanford cryptographer @danboneh explores why blockchains may turn to signatures built from hash functions. He also presents new research on threshold signing.
The talk ends with the questions Bitcoin still has to answer, including whether post-quantum signatures will require larger blocks, what happens to abandoned coins, and how someone such as Satoshi could prove ownership after Bitcoin’s current signatures have been retired.

Institutions are told that privacy rails solve their confidentiality problem.
Here's what the pitch skips: a privacy chain can upgrade its cryptography, but it can't unpublish its history.
When shielded pools falls to a quantum computer, the entire archive decrypts retroactively.
This is why Sombra didn't retrofit, we launched post-quantum from genesis on Solana without the expiry date.

When a desk like JP Morgan moves a tokenised treasury on-chain, the size, the timing and the counterparty are all public, so the market front-runs the settlement.
And there's a second problem nobody prices in: a 30-year bond outlives the encryption protecting it.
Anything shielded with today's cryptography can be harvested now and decrypted long before that instrument matures.

The privacy conversation on Solana just got a lot more interesting!
Our founders went live with @catmcgee and @deanmlittle on The Privacy Show speaking about Solana's technical progress, zk schemes, and quantum security.
Let us know what you think :)

MEV bots are watching your transactions before they land
On Solana, your transaction is public before execution. They see nothing here on Sombra.

We're talking about quantum now, not because there's an emergency today, but because waiting until there is an emergency could be much too late.
Credit to Binance for setting the standard on how to talk about this

Quantum-resistant signatures stop tomorrow's forgeries. They do nothing for yesterday's data.
Good to see TRON moving on this. The space needs more of it, and sooner.
