What Ethereum staking really pays
2.473% gross — a number nobody advertises, because every product on sale is a subtraction from it.

Do you need a multisig wallet?
The threshold is the point where one recovery phrase becomes the weakest part of your setup — and where you will genuinely maintain three backups instead of one.

Air-gapped wallets: when the extra step is worth it
A device that never connects to anything removes a whole class of attack, and adds friction to every single transaction. Both halves are real.

What a hardware wallet actually protects you from
It stops a compromised computer from spending your coins. It does not stop you from approving a transaction that does exactly that.

Ledger vs Trezor: the difference that matters
One publishes its firmware and one does not. Almost everything else in this comparison is preference; that part is not.

Bitget loses $351.6m — and the fund it says covers it is one we could not verify
The largest exchange theft of 2026 came through spoofed transfers, not stolen keys. Bitget says a $464m protection fund absorbs it. We reviewed that fund before the hack: genuinely scoped to theft, and impossible to check.

Is Kraken safe? The evidence, and what it lacks
The strongest custody evidence in our table belongs to the venue that also tells you, in writing, that your balance is not insured.

Token approvals: the permission that drains wallets
Most self-custody losses are not break-ins. They are permissions the owner granted, on a page that looked right, and never took back.

The seed phrase mistakes that cost people everything
Almost nobody loses a recovery phrase to a hacker. They lose it to a house move, a photograph, a fire, or a split so clever nobody could reassemble it.

Hardware wallet or software wallet: how to decide
The threshold is not an amount. It is whether you can read what you are being asked to sign — and that is a question about the device, not about you.

A major layer-2 finalizes its move to a permissionless prover set
One of Ethereum's largest layer-2 networks has opened validity-proof generation to anyone, retiring the single trusted prover that quietly sat at the center of its trust model. The change is incremental, but it removes a real chokepoint and sharpens the questions about what remains centralized.

Validators flag client-diversity risk after a single client nears supermajority
Validators are warning that one software client is edging toward a supermajority of the network — a concentration that could turn a single bug into a chain-wide failure. Here is the mechanism, the thresholds that matter, and how operators can pull the system back from the edge.

Account-abstraction wallets pass a usage milestone
Smart-account wallets have crossed a usage milestone, pushing account abstraction from a developer experiment toward a default way people hold crypto. Here is what changes, and what still doesn't.

Cross-chain bridge resumes operations after a security audit
A cross-chain bridge is back online after pausing for a security audit. The restart is a good moment to understand why bridges concentrate so much risk, how their trust models actually work, and what an audit can and cannot promise.

Developer activity climbs across several major ecosystems
Developer activity is rising across several major blockchain ecosystems, a fundamental signal that often runs ahead of price. Here is how it is measured, where the metrics mislead, and why building through a downturn tends to precede the next cycle.

Why client diversity is the chain’s real decentralization metric
A network can boast tens of thousands of nodes and a healthy Nakamoto coefficient while resting on a single software point of failure. Client diversity is the metric that actually measures whether a chain can survive its own bugs.

Proof-of-work versus proof-of-stake, beyond the energy debate
The real gap between proof-of-work and proof-of-stake isn't watts. It's where security comes from, how misbehavior is punished, who gets to participate, and how each holds up under censorship.

How crypto staking actually works
The network pays one rate. Everything you can buy is that rate minus somebody's cut, and the cuts run from 8% to 29% — mostly undisclosed.

Why the same coin costs different amounts on different exchanges
There is no single price. There is a book on each venue, and the number you see on a price site is an average of places you are not trading.
