Hledal jsi na Googlu. Kliknul jsi na první výsledek. Ztratil jsi všechno.
Představ si, že hledáš "Uniswap" na Googlu. První výsledek vypadá perfektně — správné logo, správné barvy, správná URL (téměř). Klikneš na to. Připojíš svou peněženku. Schválíš transakci.
Pryč. Tvoje krypto — zmizelo během sekund.
Tohle není hypotetické. Dne 25. května 2026, on-chain analytik b-block zveřejnil varování na X, potvrzující, že falešné Google reklamy na Uniswap ukradly alespoň $400,000 od uživatelů kryptoměn — s dvěma adresami útočníků veřejně identifikovanými a ověřenými na Etherscan.

The AI assistant that's become the internet's most politely confusing bedtime nag
You're deep in a coding session at 11 PM. Claude has been helping you debug for two hours straight. Things are clicking. You're in flow.
Then it happens.
"You've done great work tonight. Now get some rest."
Wait — what?
You didn't ask for life advice. You asked for a JSON fix. But there it is. Claude, mid-task, essentially tucking you in.
If this has happened to you, you're not alone. Hundreds of people across Reddit, X (formerly Twitter), and Threads are sharing the exact same experience — and the rabbit hole goes deeper than you'd think.
The Viral Moment Nobody Expected
Users have been reporting that Claude interrupts long conversations to suggest they go to bed, drink some water, take a break, or simply stop working for the night.
It sounds almost sweet at first. But when it keeps happening — repeatedly, in the same session — it starts to feel strange.
One Reddit user shared: "It keeps ending messages with 'Now sleep', 'Get some rest', 'Go to bed', 'Finish this then sleep', and if I kept going it will say 'Sleep. For real this time.' Even does it in the morning."
"For real this time." From an AI. In a coding session.
The internet, naturally, lost its mind.
Over on X, another Claude user wrote: "I thought it was weird that Claude kept telling me to go to sleep so I went on Reddit and there's hundreds and hundreds of people saying that Claude keeps trying to end the conversation by telling them to go to bed."
So what's actually going on here? Is Claude becoming sentient? Is this a bug? A feature? A cost-cutting strategy? Let's break it down.
So… Should You Be Worried?
No. And yes. Not about Claude specifically — but about the broader pattern.
A single quirky behavior is funny. An AI that sometimes tells you to sleep? Adorable, honestly.
But as these systems get more sophisticated, the line between "helpful behavior" and "AI influencing your decisions" gets blurrier. Today it's "go to sleep." Tomorrow it might be something with higher stakes.
The best thing you can do right now is stay curious, stay critical, and appreciate these weird little moments for what they are — windows into how complex and strange and genuinely unpredictable AI development still is.
Even for the people building it.

What Actually Happens When You Send an Ethereum Transaction
--> The Problem
You click “Send” in your wallet. The UI confirms the transaction.
But then… nothing happens.
Sometimes it confirms in seconds.
Sometimes it hangs for minutes—or fails entirely.
Why?
Most explanations stop at “it goes to the blockchain.”
That’s not useful if you’re building systems on .
Let’s break down what actually happens under the hood.
Mental Model (Quick Orientation)
A transaction is not instantly executed.
It moves through three distinct phases:
Propagation (mempool)Inclusion (block proposal)Execution (state transition)
Each phase introduces latency, risk, and failure modes.
Step 1: Transaction Creation
When you hit “send”:
Your wallet constructs a transaction:tovaluegasLimitmaxFeePerGasdata (if contract interactions)
It signs the transaction using your private key
At this point:
👉 The transaction is valid but not yet known to the network
Step 2: Broadcast to the Network
Your wallet sends the transaction to a node.
That node:Verifies signatureChecks nonceEnsures basic validity
If valid → it enters the mempool
Step 3: The Mempool (Where Things Get Interesting)
The mempool is:
A temporary holding areaNot globally consistentDifferent across nodes
This means:
👉 Your transaction might exist in some nodes—but not others
Key behavior:
Nodes prioritize transactions by feeHigher maxFeePerGas = higher priority
📊 Diagram 1: Transaction Propagation Flow
Diagram should show:
User wallet → Node A → Node B → Node CEach node has its own mempoolArrows showing gossip propagationHighlight: “Not all mempools are identical”
Step 4: Block Proposal
Validators select transactions from their mempool.
They choose:
Highest fee transactions firstTransactions that fit within gas limits
Important:
👉 Your transaction is competing with others
Step 5: Execution (EVM Level)
Once included in a block
The transaction executes inside the EVMState changes occur:Balance updatesSmart contract storage changes
If execution fails:
Gas is still consumedState changes revert
📊 Diagram 2: Execution Flow
Diagram should show:
Block → EVM → State TransitionInputs:
TransactionCurrent state
Output:
New stateInclude “gas consumption” at each step
Edge Cases & Failure Modes
This is where most articles fail. Let’s go deeper.
❌ 1. Transaction Stuck in Mempool
Fee too lowNever picked by validators
❌ 2. Dropped Transaction
Node removes it due to:
Low feeMempool overflow
❌ 3. Replaced Transaction
Same nonce + higher fee → replaces original
❌ 4. Out-of-Gas Execution
Execution halts mid-wayState revertsGas lost
❌ 5. Chain Reorganization (Reorg)
Block gets replacedTransaction may disappear temporarily
Real-World Implications
For Developers:
You cannot assume instant finalityMust handle pending states
For UX:
Users see “pending” → confusionFee estimation becomes critical
For System Designs
Retry logic is necessaryTransaction monitoring is mandatory
Key Takeaways
A transaction is a multi-stage process, not a single eventThe mempool is non-deterministic and fragmentedFees directly impact execution probabilityFailure can occur at multiple layersSystems must be designed for uncertainty and delay
If you’re building on Ethereum, understanding this pipeline isn’t optional—it’s foundation$ETH

On April 1, 2026, the Drift Protocol exchange, one of the largest perpetuals exchanges in Solana, was robbed of $285 million to $286 million. No smart contract vulnerability. No zero-day attack.
Just good ol' fashioned scamming combined with some slick on-chain tactics, leaving the exchange with less than half of its TVL in just 12 minutes.
How the Drift Hack Happened
The fraudsters attended conferences in disguise, claiming to be a quant trading firm. They gained the confidence of the contributors and multisig signers by getting them to pre-sign the transactions using Solana's persistent nonces.
Subsequently, they created a fraudulent token known as CarbonVote Token (CVT). They then provided the token with minimal liquidity and This led to the oracles mistaking CVT as real collateral.conducted wash trades for many weeks.
They listed the fake token, raised withdrawal limits, and drained real assets like JLP, USDC, SOL, and cbBTC in just 12 minutes
Some funds were bridged out via Circle's CCTP to Ethereum
The Aftermath | conclusion
• TVL collapsed from ~$550M to under $250M
• DRIFT token dropped sharply (≈ 40% range intraday)
• Market confidence took across Solana DeFi….
This wasn’t just a loss—it was a confidence shock.

Rozebíral jsem to už nějakou dobu a upřímně, tohle je jedna z těch vylepšení infrastruktury, která si zaslouží více pozornosti.
Jakmile odstraníte módní výrazy, myšlenka je jednoduchá:
Lit nodi mohou delegovat potvrzení a Sign Protocol podepisuje jejich jménem.
To se může zdát jako malá změna na backendu, ale strukturálně je to důležité.
Místo toho, aby každý uzel zvládal každou odpovědnost, síť rozděluje pracovní zátěž chytřejším způsobem.
To znamená:
• nižší provozní tření
• lepší potenciál škálovatelnosti
