When a DAO gets hacked, either smart contract code breaks or the governance mechanism itself gets weaponized. The two failure modes work differently, the response options are different, and what happens to funds and users depends entirely on which type you're dealing with.

When a crypto bridge gets exploited, the vault gets drained and bridged assets on the destination chain become unbacked. Here's the mechanism, the historical examples, and what determines who loses what.

A 51% attack gives an attacker majority control over a blockchain's consensus process — but what they can actually do with it is more specific (and more limited) than most descriptions suggest. Here's the mechanism, the historical examples, and why it matters more for some chains than others.

When a smart contract has a bug, the code can't be patched — it's already live on-chain, and funds are already at risk. This post maps the main vulnerability categories, what recovery options actually exist, and how the security ecosystem has developed in response.

A pending crypto transaction can sit in the mempool indefinitely when fees are too low or nonces are out of order. Here's the mechanism behind stuck transactions and what actually happens when you wait, speed up, or cancel.

A validator going offline triggers inactivity penalties — not slashing. Here's how Ethereum's proof-of-stake design distinguishes unavailability from misbehavior, and what the inactivity leak actually does.

When the last bitcoin is mined around 2140, the block subsidy disappears — but the network keeps running. Here's what changes mechanically for miners, security, and transactions, and what the open questions are.

Bitcoin's 32nd halving around 2140 ends the block subsidy entirely. After that, transaction fees become miners' only revenue. Here's how the fee market works and what it means for network security.

When a crypto exchange gets hacked, whether users recover their funds isn't determined in the moment of the breach — it's determined by what the exchange built before it. Insurance funds, cold storage ratios, and reserve coverage are the actual variables. This post maps the mechanism and historical outcomes.

A stablecoin depeg isn't always catastrophic — the outcome depends entirely on which type it is and what caused it. Fiat-backed, crypto-backed, and algorithmic stablecoins fail in completely different ways, and only one of those failure modes has no floor.

A blockchain fork is where one chain's history splits into two. Whether it stays unified or creates a permanent rival chain depends on whether the network reaches consensus on the new rules. This post explains the mechanism, the economic resolution, and why institutional infrastructure is raising the cost of successful forks.
