What is JasmyCoin (JASMY)?

It's a project that keeps the personal data made by your Internet-of-Things (IoT) devices in a 'Personal Data Locker' instead of on a company's servers. If a business wants to use that data, it has to ask your permission and pay for it in JASMY tokens. The big slogan is 'data democracy', giving data back to the people who actually own it.

Who created JasmyCoin?

Jasmy Corporation, based in Tokyo, Japan, started it in April 2016. The founding team came from Sony, most notably Kunitake Ando, who was Sony's president from 2000 to 2005. That's why JASMY is often called Japan's 'data sovereignty' coin.

Does JasmyCoin have its own blockchain?

No. JASMY isn't its own blockchain, it's an ERC-20 token that runs on Ethereum. So it borrows Ethereum's proof-of-stake (PoS) for consensus, and there's no mining (PoW) of its own.

How many JasmyCoins will ever exist?

There's a hard cap of 50 billion (50,000,000,000), and no new coins are minted, so there's no inflation. It's the same 'fixed supply' idea as Bitcoin, just a much bigger number. About 98% (roughly 49.4 billion) is already in circulation.

💬 “Your information belongs to you. It stays in the vault on my back. A company can borrow it, but only if you say yes first, and only after it pays me in JASMY. 🗡️”

💬 TL;DR

The data your IoT gadgets make goes into a Personal Data Locker that belongs to you, not to a company's servers.
Want to use someone's data? Get their permission, then pay in JASMY. That's the whole idea: "data democracy."
Started in Tokyo in 2016 by former Sony executives, including a man who'd run Sony as its president.

📖 The Story

Think about how much your gadgets quietly record. Your watch knows how you slept. Your phone knows where you went. Normally all of that gets shipped off to a company's servers, and you never see a cent of what it's worth. JasmyCoin starts from a simple complaint about that: it isn't really their data. It's yours.

The people who built it were not crypto kids. Jasmy Corporation set up shop in Tokyo in 2016, and the team came out of Sony, including Kunitake Ando, who ran Sony as its president from 2000 to 2005. Their fix is the Personal Data Locker, a vault that holds what your devices record and answers to you instead of a company.

So picture our samurai standing guard at that vault. A company walks up wanting your sleep data. He doesn't just hand it over. First he checks whether you actually said yes. Then he charges rent, paid in JASMY, and that payment goes back to you. The fancy name for all this is "data democracy." The short version is the line he keeps repeating: your information is yours.

🧩 How it works

The data your IoT devices (things like watches and cameras) create doesn't go to a company's warehouse, it goes into your Personal Data Locker (PDL). When a company wants to use it, a gatekeeper that handles permissions and audit logs (the SKC) checks “Did the owner say yes?”, and the company has to pay in JASMY before the vault opens. That toll flows back to the data's owner. JASMY doesn't build a brand-new blockchain of its own, it's an ERC-20 token on Ethereum, so it leans on Ethereum (PoS) for verification.

⌚ Your data sits in the 🗝️ Personal Data Locker, and if 🏢 a company wants it, it asks your permission and pays in JASMY.

🌗 Light & Shadow

🌕 Light

The pitch is easy for anyone to grasp: "your data is yours"
Behind it sits a real Tokyo company with Sony-bred founders, not an anonymous team (established 2016)
Supply is capped at 50 billion and no new coins are minted, so inflation isn't eating away at it

🌑 Shadow

It has no chain of its own. It's an ERC-20 token on Ethereum, so whatever happens to Ethereum tends to splash onto JASMY too
About 98% of the supply is already circulating, leaving little fresh demand from new coins coming online
The big question is whether companies actually pay to use the data marketplace at scale. Until they do, the price mostly rides on news and hype

🧬 Evolution lineage

JasmyCoin isn't a fork or a sibling of another coin. It was born on Ethereum as an ERC-20 token, so it leans on Ethereum's PoS for verification. There's no separate L1 bloodline.
