Beginner's Guide
The execution layer for parametric insurance,explained simply.
No insurance jargon. Just the story of why a massive protection gap exists in Japan, how parametric insurance addresses it, and how a Shared Execution Layer makes it work at Lloyd's.
The Risk
Japan has real demand for parametric cover — with a massive protection gap.
Japan sits on 4 tectonic plates. Major earthquakes occur regularly, causing catastrophic economic losses. Yet most of those losses go uninsured — a protection gap that parametric insurance is uniquely suited to close.

Two Approaches
Traditional insurance vs. Parametric insurance
Traditional insurance pays based on assessed damage — slow and subjective. Parametric insurance pays automatically when a pre-agreed trigger is met. No claim forms. No assessment. Just: did it happen? Then pay.
❌ Traditional Insurance — Slow & Opaque
The result:
Months of waiting • Opaque process • May be denied • Cash flow crisis during rebuilding
✅ Parametric Insurance (DeIn) — Automatic & Fast
The result:
Next-day payout • Transparent trigger • No subjectivity • Cash available exactly when you need it
The Industry
Who are the players in (re)insurance?
Insurance doesn't go directly from you to a single company. Risk flows through a chain of specialists — each adding value, but also adding delay and paperwork. Today, each participant maintains their own version of the same transaction. DeIn sits at the MGA layer and replaces that fragmentation with a Shared Execution Layer.
Lloyd's Syndicate
Capacity Provider
Provides the capital. Sets the terms and limits for how much insurance can be written.
DeIn (MGA / Coverholder)
DeIn's roleManaging General Agent — on Blockchain
Designs and manages earthquake parametric insurance products on behalf of Lloyd's. All operations run on blockchain — real-time pricing, automatic bordereaux, live capacity.
Broker
e.g., AON, Willis
Finds the right insurance product for the client. Places the risk with the right insurer.
Enterprise
The Insured
The business that needs insurance coverage against earthquake risk. Onboards quickly and receives automatic payouts.
DeIn's positioning: As an MGA (Coverholder), we design and manage Lloyd's products and deliver them to insurers and enterprises through brokers — with all operations on blockchain.
Before & After
The old way vs. the DeIn way
The same players — but everything changes when operations run on blockchain instead of paper and spreadsheets.
Traditional Flow — Manual & Slow
High operational burden: Audit & reconciliation take weeks · High oversight cost · Slow to delegate underwriting authority
DeIn Flow — Shared Execution Layer
We don't replace existing systems. We replace reconciliation. Eliminate manual processes · Dramatically shorten audit · Enable new risk transfer & capital allocation
The Technology
How blockchain transforms an earthquake into a payout
Five components work together automatically. No human intervention required.
01
Smart Contracts
Terms, triggers, pricing and payments are coded and executed automatically on Ethereum.
02
On-chain Data
All transactions are recorded immutably. Anyone with permission can verify — permanently.
03
Oracle (Chainlink)
Trusted seismic data is securely fed into the blockchain. Triggers are validated in real time.
04
Automated Settlement
Trigger is verified and payment executes automatically. Fast, transparent and immediate.
05
Auto Reporting
Bordereaux and all reports are auto-generated from contract data. Real-time, audit-ready.

Why Blockchain?
A contract that enforces itself
Software and AI can detect problems and flag them. Only a shared execution layer on blockchain can prevent them from happening at all — and replace reconciliation entirely. For earthquake insurance, where payouts are irreversible, prevention is everything.
Rules Can't Be Broken
A traditional MGA can accidentally bind beyond its mandate. In DeIn, it's system-impossible — the smart contract rejects the transaction before it completes.
Example: An MGA allowed to write ¥10B of cover tries to write ¥11B. The blockchain rejects it automatically — no human oversight needed.
Everyone Sees the Same Data
Today, insurers, MGAs and brokers each maintain separate books that must be manually reconciled. DeIn uses one shared ledger — like a live shared document no one can delete.
Example: The syndicate in London sees the exact same capacity data as the MGA in Tokyo — in real time, with no emails or spreadsheets.
Payout Must Be Right Before It Fires
Once an earthquake triggers a payout, it's automatic and irreversible. It can't be clawed back — so the rules must be enforced before the event, not reviewed after.
Example: When Mw 7.0 is detected, the smart contract verifies all conditions and sends payment within 24 hours, with a permanent blockchain record.
The Value
What changes when DeIn is the operating layer
Faster Product Launches
Launch parametric products faster. Reuse components across perils and regions — weeks, not months.
Lower Operating Costs
Eliminate manual work and reconciliations. Reduce back-office costs and oversight burden.
Automated Settlement
Payouts triggered automatically. Next-day settlement, no claims process.
Better Capacity Utilisation
Real-time view of exposure and capacity. Optimize capital allocation across products & regions.
