Gas measures computational effort, not money. Since EIP-1559 the fee splits in two, and the larger part, the base fee, is burned out of existence rather than handed to a validator.
A blockchain is a shared ledger of transactions grouped into blocks, each one cryptographically linked to the block before it. NIST's own report deliberately dropped the word immutable, and the reason it did is the most useful thing to understand about how these systems work.
Attackers hijacked the domains of about a dozen DeFi sites registered with Name.com late on October 30, pointing visitors to fake pages that drained their wallets. No smart contract was breached. Early estimates of the theft run from about $138,000 to $202,386.
The UAE has no personal income tax or capital gains tax, so individuals pay nothing on crypto profits. A 2024 decision also removed VAT from virtual asset transfers. Tax still applies once trading becomes a business.
Open interest tracks how many futures contracts are still live, not how many changed hands. It tells you whether money is flowing into a market or leaving it. Here is how to read it, with a dated example, and why it never says which way price will go.
Binance switched its Bitcoin network back on first, three days after thieves took about $6.3 billion from its hot wallets. The exchange says it has replaced most of the missing crypto itself and will cover the rest.
Strategy's third-quarter operating profit hit a record $20.9 billion, almost all of it an accounting gain on its 848,517 bitcoin. On the same day, the company said chief financial officer Andrew Kang will resign for personal reasons, effective November 5.

Gas fees are what you pay miners or validators to process your transaction.
Our read: Only part of it. Ethereum's own documentation says the base fee is destroyed when the block is created, removing it from circulation. The validator keeps the priority fee, the tip, which is normally the smaller component.
Data written to a blockchain is immutable and can never be changed.
Our read: NIST's final report calls blockchains tamper evident and tamper resistant, not immutable. The draft said immutable and the published version changed it. Altering an old block is possible; it is detectable, and on a large chain it is expensive enough that nobody bothers.
The affected projects stress that their smart contracts were never breached, framing the attack as an outside domain problem rather than a failure of their apps.
Our read: That holds up as far as it goes. On-chain analysts at The Block and Bitquery confirm the contracts were untouched and the theft came through hijacked domain records. Yet the front end is the part users actually touch, and blame between Name.com and Vercel is still unresolved, so a clean contract did not keep users safe.
Binance says it has made users whole, covering about 95% of the $6.3 billion stolen with its own funds and reopening withdrawals in phases.
Our read: Withdrawals did reopen and Binance quotes named officials, but the coverage figures are the company's own, around 10% is still outstanding in less liquid tokens, and a full zero knowledge proof of reserves had not landed as of 1 November.

The reward for mining a block is cut in half every 210,000 blocks. It has happened four times, the subsidy is 3.125 bitcoin today, and the next cut is about 76,800 blocks away.
A powerful enough quantum computer could forge Bitcoin signatures in theory. No such machine exists, and the distance between today's 105-qubit chips and the millions an attack would need is still vast. Here is what is real, what is years away, and what Bitcoin is already doing about it.
A breach of Keystone's website exposed customer names, shipping addresses and order details, the hardware wallet maker said. It confirmed the theft on October 23 and said recovery phrases and private keys were safe, but the leaked contact data still opens the door to phishing and worse.

Blockchain analytics firm Chainalysis says suspected North Korea-linked hackers were behind nearly 89% of reported crypto hack losses in 2026, a share driven mostly by the $6.4 billion Binance breach it blames on a group called TraderTraitor.

A minting bug on the Initia blockchain let an attacker create unbacked tokens and move about $2.7 million to Ethereum before the network was stopped. A day later the chain and its rollups stayed offline, with no restart date and no final loss figure.
Five Ethereum researchers filed a draft consensus design on October 21 that aims to cut the time a transaction takes to become final, from about 16 minutes to roughly four. The proposal, EIP-8453, is only seeking a number to enter the formal upgrade process.

US spot bitcoin ETFs recorded $643 million in net redemptions on 30 October 2026, the biggest single-day outflow since June, as bitcoin fell toward $77,000 and ether funds extended a fifth day of losses.
Crypto sell-offs look chaotic, but most trace back to the same handful of causes. Leverage that unwinds fast, a shift in interest-rate bets, money leaving spot ETFs, and the mood across riskier assets. Here is how each one pushes prices lower, with real examples.
