Restaking Explained: How EigenLayer Works (Rewards, Risks, and What Could Break)

DeFi & Staking /

Restaking Explained: How EigenLayer Works (Rewards, Risks, and What Could Break) Restaking is one of the year’s defining narratives. Capital keeps flowing into EigenLayer, new Actively Validated Services (AVS) are shipping, and operators are competing for delegations. But beyond the buzz, builders and depositors need a clear view: What actually happens to your ETH or […]

Privacy Coins vs Compliance: Practical Controls for Real-World Risk What counts as privacy tech, why people use it, how regulators view it, and how to design risk-based controls that protect users while meeting obligations. Heads-up: Education, not legal advice. Rules vary by jurisdiction and change quickly. Confirm locally with counsel and your regulator before launching

Regulatory Approaches Worldwide: How Regions Supervise Crypto and Web3 A practical map of global frameworks: who needs a license, what rules apply, how stablecoins and market conduct are treated, and where privacy-preserving compliance fits. Heads-up: This is general education, not legal advice. Rules change and vary by country, business model, asset type, and licensing status.

RPCs and Nodes (Clients, Reliability, Security)

Nodes, L1/L2, Rollups, DeFi & Staking, Smart Contracts /

RPCs and Nodes: Accessing the Chain Reliably and Safely Node types, JSON RPC patterns, reliability architectures, and production grade security practices for real dapps. TL;DR: Pick deliberately between public endpoints, hosted providers, and self run nodes (full or archival). Build resiliency with multi provider failover or quorum RPC. Build safety with chain checks, simulation, finalized

Storage (IPFS, Arweave, Filecoin)

NFTs & Token Standards, DeFi & Staking, Smart Contracts /

Decentralized Storage: IPFS, Arweave, and Filecoin Content addressing, permanence versus leases, gateways, pinning, proofs, and production patterns for NFTs, dapps, analytics, and archives. TL;DR: IPFS is a content-addressed peer-to-peer layer that gives you CIDs and global retrieval; availability depends on pinning and gateways. Arweave offers “permanent” storage by funding long-term replication up front; content is

Indexing and Querying (The Graph)

DeFi & Staking, Nodes, L1/L2, Rollups, Smart Contracts /

Indexing and Querying: The Graph, Subgraphs and GraphQL From raw on chain events to queryable APIs: subgraph schemas, mappings, indexing economics, and production grade query patterns. TL;DR: The Graph turns contract events and call results into a GraphQL API using a subgraph that declares a schema, a manifest of what to watch, and mapping functions

Oracles (Chainlink, Pyth)

Blockchain Basics, DeFi & Staking, Smart Contracts /

Oracles: Bringing Real-World Data On-Chain (Chainlink and Pyth) Price feeds, verifiable randomness, automation, and cross-chain messaging, plus common failure modes and how to harden your contracts against them. TL;DR: Oracles bridge off-chain facts to on-chain programs. You will encounter two dominant patterns: push oracles (for example Chainlink aggregators that periodically post a price on chain)

Homomorphic Encryption (HE): Compute on Encrypted Data

Smart Contracts, DeFi & Staking /

Homomorphic Encryption (HE): Compute on Encrypted Data Partially, somewhat, and fully homomorphic schemes, what they enable, how they work at a high level, and where HE fits next to zero-knowledge and blockchains. TL;DR: Homomorphic encryption lets you perform operations on ciphertexts so that, after decryption, you get the same result as if you had computed
