Most blockchain projects fail before the first block is mined. Not because the technology doesn't work — because nobody asked the right questions before they started building.

This checklist will save you from the most expensive mistake in enterprise blockchain: implementing something you didn't fully think through.

Answer all 25 questions. If you can't answer one, don't proceed until you can.

Most enterprise blockchain guides start with Docker Compose files, Kubernetes manifests, and certificate authority configuration. They assume you have a dedicated infrastructure team, three months of runway, and a tolerance for YAML-induced headaches.

This guide takes a different approach. It starts with why you'd implement a blockchain, walks through what architecture to choose, and shows how to deploy it with the same operational complexity as any other Node.js application.

Every enterprise blockchain project starts with a meeting. In that meeting, someone says something that isn't true. Five myths, specifically. They sound reasonable. They sound informed. And they'll lead your project into a ditch if you don't catch them.

Here are the five myths I encounter most frequently — and what you should believe instead.

The blockchain industry has a credibility problem: too many whitepapers, too few deployed systems. Every conference pitch promises "revolutionary transparency" and "trustless coordination." Then you ask "what's the ROI?" and the presenter suddenly needs to take a call.

I've spent 5+ years working with teams deploying blockchain in production. Here are the 7 use cases where the math actually works — with numbers, timelines, and the specific problem each solves.

Healthcare data sharing is the classic enterprise blockchain use case that's been promised for a decade and delivered almost nowhere. The problem isn't technology — it's that the technology was too complex for the organizations that needed it.

A regional healthcare network typically involves: 3-8 hospitals, 2-4 insurance carriers, dozens of specialty clinics, pharmaceutical companies running clinical trials, and public health agencies. Each operates its own EHR system. Each has different data formats, privacy policies, and access control rules. Each is legally prohibited from sharing certain data without explicit patient consent.

A permissioned blockchain with per-record encryption and consent management solves the coordination problem without requiring any single organization to centralize control of the data.

When organizations evaluate blockchain platforms, the conversation usually starts with features: consensus algorithms, smart contract languages, privacy models, and throughput benchmarks. Rarely does anyone ask: "What will this actually cost us to run in production?"

That question is where most enterprise blockchain projects fail. Not because the technology doesn't work — but because the ongoing operational cost burns through budgets and patience long before the project delivers ROI.

Here's an honest, line-by-line breakdown of what Hyperledger Fabric costs to operate, and what a simpler alternative looks like.

Inter-bank reconciliation is one of the most expensive, slow, and error-prone processes in finance. Banks maintain independent ledgers. At the end of each day (or each settlement cycle), they compare records to identify discrepancies. Differences must be investigated, resolved, and re-posted — a process that takes hours to days and costs the industry billions annually.

A permissioned blockchain shared between participating banks eliminates this reconciliation process entirely. Instead of each bank maintaining an independent ledger and reconciling after the fact, all banks share a single, cryptographic ledger that updates in real time.

The single most important architectural decision in any blockchain project is whether the network is permissioned or permissionless. It determines your consensus mechanism, your privacy model, your performance ceiling, your regulatory exposure, and your infrastructure costs.

Yet most articles on this topic are either religious ("permissionless is the only real blockchain") or sales pitches ("our platform supports both!"). Neither helps you decide.

Here's the technical truth, side by side, with no agenda.

"Which blockchain should we use?" is the wrong question. The right question: "What trust model does our use case require?"

The answer determines everything — your architecture, your infrastructure budget, your team composition, your regulatory exposure.

Here's the decision framework I use with every team evaluating blockchain. It starts with trust, not technology.

Consensus is the hardest problem in distributed systems, and blockchain platforms make it harder by treating every consensus algorithm choice as a religious debate. PBFT loyalists dismiss Raft as "not real consensus." Raft proponents point out that PBFT adds complexity most enterprise networks don't need.

The truth: for enterprise consortiums where all participants are known and bound by legal agreements, Raft-based Crash Fault Tolerance (CFT) is the pragmatic choice. Here's why, how it works, and when you actually need Byzantine Fault Tolerance (BFT).
