[1/9] "Don't Trust, Verify"
–Ein Spruch, der derzeit die Runde macht, nachdem Unsummen von Milliarden durch #FTX und #SBF veruntreut wurden–

5 Begrifflichkeiten, die du jetzt unbedingt verstehen musst, um Exchanges besser einschätzen zu können!
🧵👇
[2/9] 👉 "#Merkle #Tree"

• Ist ein binärer #Hash-Baum, also eine Datenstruktur in der #Kryptografie, bei der jeder Blattknoten ein Hash-Wert eines Datenblocks darstellt
• Nachträgliche Änderungen wirken sich auf die "Wurzel" aus
• Effizientes Mittel der #Datenüberprüfung My User ID: Satoshi My BTC ...Merkle Root da8fc, Merkle B...
[3/9] 👉 "#Proof of #Reserves"

• Der Beweis durch einen unabhängigen Prüfer, dass der #Exchange tatsächlich ALLE #Assets (Einlagen und Salden) besitzt, die er vorgibt zu haben
• Während des #PoR wird der "anonymisierte #Snapshot" der Salden zu einem Merkle Baum zusammengesetzt Proof of Reserves Source: h...
[4/9] • Ab diesem Zeitpunkt, wird die "Wurzel" bestimmt, also ein Fingerabdruck, der alle Salden des #Exchanges einzigartig identifiziert
• In Kombination mit den dig. #Signaturen der veröff. #Nodes und deren Gelder, können im #Audit die Reserven und #Assets nachgewiesen werden Merkle Tree Hashes Source: ...
[5/9] 👉 "#Proof of #Liability"

• Ähnlich wie beim #PoR muss auch hier mit einem #Audit (z.B. mit einem #Merkle #Tree) bewiesen werden, dass ein #Exchange die Benutzersalden (#Verbindlichkeiten) nachweisen kann, ohne persönliche Informationen preiszugeben Example Merkle Tree for PoL...
[6/9] 👉 "#Proof of #Solvency"

• Ein anderer Begriff für den Nachweis eines #Exchanges liquide und Zahlungsfähig (#Solvent) zu sein.
• Kann ein Exchange, durch ein Audit, einen PoR ablegen und diesen mit einem PoL abgleichen, kann davon ausgegangen werden, dass er solvent ist. Site solvent! 362382 surplu...
[7/9] 👉 "Not your #keys, not your #coins"

• Die vorher benannten #Proofs sind alle nahezu wertlos, aber dennoch wünschenswert, erfüllen sie doch den Zweck der #Transparenz.

Nur die #Assets, die in "#Selbstverwahrung" eurer #Wallet zugeordnet sind, gehören immer euch ‼️ THIS IS WHY I DIDN'T WANT T...
[8/9] ⚠️ Folgendes kann im #Proof of #Solvency nicht sichergestellt werden:

• Die Priv. Keys könnten längst verloren/gestohlen oder dupliziert worden sein
• Kurz vor dem Audit könnten Gelder ausgeliehen worden sein, um den Nachweis zu bestehen
• Prüfer müssten unabhängig sein Achtung WICHTIG!!! Source: ...
[9/9] Lasst euch nicht verunsichern und bleibt weiter wachsam! 🧐

Fragt euch, ob ihr nicht endlich die Verantwortung über eure Gelder selbst in die eigene Hand nehmen wollt und verwahrt eure Keys bei euch selbst!

Hardware-Wallets und Software-Wallets gibt es schließlich genug😉

[1/🧵] Crashcourse XRP Ledger Permissioned DEX!

With the introduction of credentials, permissioned domains and permissioned DEXs the XRPL will evolve into a completely new type of beast!

No tech depth ahead, just the basics. 👇 Source: @krippenreiter
[2/21] — The Identity Tech Stack —

For pDEXs to exist and work as intended, three different features need to be active on the XRP Ledger:

🔸 (optional) DID ✅
🔸 Credentials ✅
🔸 Permissioned Domains ⏸️
🔸 Permissioned DEX ⏸️ Source: @krippenreiter
[3/21] — 1⃣ TL;DR —

The TL;DR is that pDomains are restricted environments on the XRPL that let users with permission use certain functions within the domain, like a DEX, in case the user owns the correct credentials. 🧐

Too much jargon, I know. 😅 Source: https://xrpl.org/docs/concepts/tokens/decentralized-exchange/permissioned-dexes#key-roles-in-a-permissioned-dex

[1/🧵] The bullrun seems to be just around the corner, and everyone is teasing us with yield and XRPFi protocols. 🧐

Regardless of whether you decide to hold or sell...

Let's take a look at "Lending" and check if it's worth it. 👇 Source: https://finematics.com/lending-and-borrowing-in-defi-explained/
[2/14] — 1⃣ Money Markets —

Before we do just that, let's quickly clarify a specific word first.

Behind the terms "Lending" and "Borrowing" actually hides another term that you will see from time to time:

🔸 Money Markets Source: https://chain.link/education-hub/decentralized-money-markets
[3/14] — 2⃣ Money Markets —

Besides AMMs, lending is currently the most important pillar for on-chain DeFi, as it removes the middleman in the pooling, management, and lending of funds.

The goal? 🤨

Positive yield or in other words, interest on the liquidity you provide. Source: https://www.investopedia.com/terms/i/interest.asp

[1/🧵] A MASSIVE attack on the JavaScript ecosystem is currently underway. ☹️

Since JavaScript is at the heart of what we use every day to browse the internet, you MUST be extra vigilant.

Let's take a look at a possible solution for the XRP ecosystem. 👇🧵 Source: https://xrplfirewall.com
[2/13] — 1⃣ First things first —

Although the entire JavaScript ecosystem is at risk, the malware appears to be targeting only a few blockchain ecosystems, based on the addresses it uses to steal funds:

‼️ At risk 👇 Source: https://jdstaerk.substack.com/p/we-just-found-malicious-code-in-the
[3/13] — 2⃣ First things first —

The reason this is such a big deal is because of the sheer volume of weekly downloads of the maliciously patched packages. Source: https://jdstaerk.substack.com/p/we-just-found-malicious-code-in-the

[1/🧵] You've probably heard about new yield opportunities with XRP that promise a return of around 20% APY. 🧐

How much truth is there to this, and what happens if you actually connect to @moremarketsxyz and deposit funds? 👇
[2/14] — 1⃣ First things first —

👉 I want you to repeat after me:

"I will not deposit all my XRP into completely new DeFi protocols right after their launch, no matter the yield" Source: @krippenreiter
[3/14] — 2⃣ First things first —

When you join any DeFi protocol, start with very small amounts (e.g., 1 XRP) to get a feel for how things work, and try to regularly withdraw everything to test whether you can realize your profits with the protocol or not. 👍 Source: https://app.moremarkets.xyz

[1/🧵] What's still upcoming and in the pipeline for the XRP Ledger? 🧐

My attempt to summarize what the brilliant @aanchalmalhotre "casually" laid out in a 25-minute talk at XRPL Apex this year. 👇 Source: https://www.youtube.com/watch?v=UzbHAbBtLXQ
[2/15] — 1⃣ Key-Challenges —

Privacy and compliance are at odds with each other, and balance is key.

A lot of what the TradFi world is used to and expects still doesn't exist or is purposefully different in blockchains, like transparent transactions or low confidentiality. Source: https://www.youtube.com/watch?v=UzbHAbBtLXQ
[3/15] — 2⃣ Key-Challenges —

Institutions also expect their on-chain operations, aka transactions, to be highly customizable and controllable because of factors like internal risk management.

👉 They expect the XRPL to be programmable for their dedicated policies. Source: https://www.youtube.com/watch?v=UzbHAbBtLXQ

[1/🧵] XRP Ledger ✖ Axelar ✖ XRPL EVM Sidechain ✖ Squid ‼️

With all these new integrations and partnerships, I bet you are pretty much overwhelmed by all the alien-like jargon. 🤨

A little vocabulary crash course ahead 👇 Source: https://axelarscan.io
[2/20] — 1⃣ Overview —

What just happened today is nothing less than the complete onboarding of the XRPL to the vast and entire web3 blockchain ecosystem (+ Bridging protocols and available liquidity).

👉 All via the XRPLEVM sidechain, Axelar and @squidrouter. Source: https://axelarscan.io
[3/20] — 2⃣ Overview —

What does this mean in practice? 🧐
🔸 New tokens on the XRPL DEX (bridged by @axelar)
🔸 Literal (and easy) any-to-any swaps (via Squid)
🔸 Liquidity from the entire web3 ecosystem (via CORAL)
🔸 Bridged XRP accessible on 80+ chains (through XRPLEVM) Source: @squidrouter
