PBS Auction and MEV-Boost: How Ethereum Blocks Get Built
Most Ethereum blocks are assembled by a small market of specialist builders. Learn how PBS auctions, MEV-Boost, relays, and censorship risks work.

What Is Danksharding and Data Availability Sampling?
Danksharding uses erasure coding and data availability sampling so light nodes can verify massive blob throughput without downloading it. Here is how it actually works.

What Is a Based Rollup and Why It Matters
A based rollup borrows Ethereum's sequencer instead of running its own. That single design choice reshapes who controls transaction ordering and who captures MEV.

What Is a ZK Coprocessor and Why It Matters for DeFi
A ZK coprocessor lets contracts verify computations over old blockchain data without replaying it on-chain, but proving cost and latency still matter.

What Is Chain Abstraction and ERC-7683? A Plain-English Guide
Chain abstraction promises one signature across any blockchain. ERC-7683 is the emerging standard that makes it work. Here is how intents, fillers, and cross-chain settlement actually fit together.

How to Evaluate an L2 Bridge Before You Cross It
Bridges remain the single largest hack surface in crypto. A 7-point checklist covering audits, finality, TVL, and exit windows helps separate safe bridges from the next exploit.

What Is Danksharding? Ethereum's Next Scaling Step Explained
Danksharding is Ethereum's multi-year plan to make Layer 2 rollups cheap by scaling data availability, but most of it isn't built yet.

Intents and ERC-7683: How Cross-Chain Crypto Swaps Work
Intents let crypto users declare an outcome instead of signing a transaction. ERC-7683 standardizes that promise across chains like Ethereum, Uniswap, and Across.

What Is a Decentralized Options Protocol?
On-chain options protocols let anyone buy or sell crypto options without a broker, but volumes are still tiny compared to Deribit because liquidity provision is brutally hard.

What Is MEV in Ethereum and Why Does It Matter?
MEV is the hidden value extracted by reordering blockchain transactions. Learn who captures it, how sandwich attacks work, and why it's a tax on every DeFi user.

Data Availability Sampling Explained: How DAS Scales Blockchains
Data availability sampling lets light nodes verify huge blocks by checking a few random chunks. It is the engine behind Ethereum's PeerDAS and Celestia's design.

What Are Based Rollups and Why They Use Ethereum's Validators
Based rollups let Ethereum's own validators order transactions, removing the L2 sequencer. That sounds simple, but the trade-offs in latency and composability are real and worth understanding.

What Is ERC-4337 Account Abstraction? Plain-English Guide
ERC-4337 is an Ethereum standard that turns every wallet into a programmable smart contract, killing seed phrases and letting someone else pay your gas. Here's how it actually works.

Modular vs Monolithic Blockchains: A Plain-English Breakdown
Modular chains split the four jobs of a blockchain into separate layers; monolithic chains do all four at once. Neither design has clearly won, and the trend in 2024–2026 is blurring the line.
