[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/🧵] The XRP Ledger is about to level up! 🔥

With all of the proposals, discussions, and development going on right now, here is a thorough, high-level summary of what is in the pipeline 👇 Source: @krippenreiter
[2/18] — DID —

Status: 🟢 Voting (new bugfix in v2.2.0)

DID is for sharing & controlling your own individual digital identity on the XRPL, while the personal data that your ID links to is held off-chain.

Use Cases:
• Reusable KYC
• Permissioned, regulated, and compliant DEX Source: https://www.w3.org/TR/did-use-cases/#uc
[3/18] — XChainBridge —

Status: 🟢 Voting (new bugfix in v2.2.0)

Allows for cross-chain asset transfers across distinct independent ledgers, such as a mainchain (e.g. XRPL) and a sidechain (e.g. EVM-Sidechain).

Use Cases:
• (w)XRP to be the native asset on a sidechain
• EVM-InteroperabilitySource: https://github.com/XRPLF/XRPL-Standards/tree/master/XLS-0038d-cross-chain-bridge

[3/13] — Biggest misconceptions about XRPL —

Myths:

[1/🧵] The crypto bullrun has begun, but fraud is on the rise again, so I've curated a list of all the ways you're likely to fall victim to it.

Here's how they'll steal your money in the next cycle. 👇 Source: @krippenreiter
[2/16] — Advance Fee Fraud —

🔸 A scheme that demands an upfront payment after establishing trust.

One example is a seemingly legitimate loan offered to the victim in exchange for a minor advance payment. Source: https://www.financestrategists.com/uploads/How_Advance_Fee_Fraud_Schemes_Operate.png
[3/16] — Affinity Fraud —

🔸 Fraud that targets certain groups by offering an investment opportunity within the community to legitimate it.

[1/🧵] $XRP Ledger AMM is still not live on the mainnet, and you might be asking:

Why? 🤨

🔸 Why do we care about amendment-blocking?
🔸 Why does updating nodes take so long?
🔸 What is the real issue, & what should we do next?

Allow me to explain what this is all about 👇Source: @krippenreiter
[2/17] — 1⃣ The Basics — Why?

Before we go into the details, it's important to understand the basics of why things take so long

Beginning with the fact that amendments represent new features or changes to TX processing

This also holds true when considering simple bug fixes Source: https://xrpl.org/resources/contribute-code/#amendment-implementation
[3/17] — 2⃣ The Basics — When?

New amendments, such as the AMM, are regularly proposed w/ new server software versions, which we track w/ each "rippled" release.

So when we talk about upgrading nodes and versions, keep in mind which amendments were introduced w/ what version. Source: https://github.com/XRPLF/rippled/releases

[3/17] — 2⃣ Summary —

Despite David's explicit statement that he posted this idea as a member of the XRPL community, others are implying otherwise.

This led to the following post, which aimed to address any concerns and commonly asked questions:
