Forget the buzzwords. A blockchain is a notebook that thousands of computers around the world keep a copy of, and that no single person can rewrite.

When you upload a file with PStorage#1, the file is cut into small encrypted pieces ("chunks") and each piece is written into that notebook as a numbered entry. Every entry is chained to the previous one by a cryptographic fingerprint. If someone tried to change one entry, every fingerprint after it would break, and every honest computer in the world would immediately reject the fake notebook.

This is why we say it is immutable: once an entry is written and confirmed, it stays there. Not because a company promises to keep it, but because changing it is mathematically harder than rewriting the internet.

Gmail, Yahoo, iCloud, Dropbox, Google Drive are centralized. One company holds your data, on a few servers, behind one login. If that company is breached, your data is breached. If that company is hacked by AI-driven attackers who automate password guessing at industrial scale, your account falls. If that company decides to close your account, your data is gone. If it goes bankrupt, your data goes with it.

A blockchain is the opposite. It is not stored in one building. It is not owned by one company. It is copied on thousands of independent computers across dozens of countries. To hack it, an attacker would have to compromise more than half of the entire network at once — an attack that would cost billions of dollars and is practically impossible for Bitcoin or Ethereum.

• No single point of failure: no server to breach, no admin account to steal, no customer database to dump.
• No one can erase your data: not the author of this app, not the blockchain foundation, not a government, not you.
• No one can sell your data: no company owns it.
• No account suspension: no one can ban you from your own storage.
• No downtime: the network runs 24/7, forever, as long as at least one computer is running.

Your password is the only key. It never leaves your device, never touches a server, never transits through an email system that AI attackers love to target. You are the only one who can decrypt your files — and the only one who can lose them.

Physical things can be lost. A USB key can burn in a house fire. A hard drive can drown in a flood. A safe can be stolen. A printed paper can be thrown away by mistake. A cloud account can be locked overnight after a billing issue. All of these are real risks that destroy data every day.

On-chain data does not have this problem. Your encrypted file is not on a single disk. It is copied on hundreds of computers around the world. If a fire burns down one data center, the copies elsewhere are untouched. If a flood destroys one country's nodes, the rest of the world keeps serving. If a thief steals your laptop, they get your wallet — which you can replace from your seed phrase — but the file on-chain stays exactly where it is, accessible from any other device.

What can still be lost:

• Your password, if you don't write it down somewhere physical.
• Your wallet's seed phrase, if you don't keep a paper backup.
• Your ability to remember which contract address and MediaId belong to which file — this is why the app gives you a backup JSON after every upload.

The file itself stays on the blockchain. The only thing you can lose is the key to open it. Treat the key like the paper title of a house: you can lose the house if you lose the title, but the house itself does not move.

PStorage#1 is not a novelty. It is a practical answer to a real problem: the data you cannot afford to lose, and that no cloud company can honestly promise to keep safe forever. Here is what it concretely solves for different people:

• Families — letters to loved ones, wills, birth certificates, photos of ancestors, voice notes for the next generation. If a fire destroys the house, the memories survive on-chain.
• Doctors and nurses — critical patient notes, encrypted case histories, remote-consultation records that must outlive any hospital's IT migration.
• Lawyers and notaries — contracts, evidence, signed agreements, sealed documents that cannot be tampered with after the fact.
• Accountants and business owners — ledgers, receipts, supplier agreements, insurance certificates that survive the closure of a company or the death of an accountant.
• Photographers and artists — original files with a provable creation date on-chain, usable as proof of authorship in a copyright dispute.
• Developers — source code, signing keys, deployment scripts, configuration files, all encrypted and globally retrievable.
• Journalists and whistleblowers — sources, notes, leaked documents that no one can seize, censor, or delete.
• Activists and citizens in oppressive regimes — proof of human-rights abuses, testimonies, evidence that no government can erase from the world.
• Anyone whose email has ever been breached — a password list or a seed phrase that no AI-driven Gmail hacker can reach.
• Small businesses — backup of critical files that outlive the closure of a bank or a hosting provider.

In every case, the pattern is the same: data that must survive the loss of a company, a device, a fire, a war, a regime, an accident, or a human error. That is exactly what a blockchain does, and exactly what PStorage#1 gives you as a simple, encrypted interface.

PStorage#1 lets you upload any file — a document, a photo, a password list, your private keys, a will, an important contract, your source code — encrypted with your password, and store it permanently on the blockchain. No server. No company. No one can delete it, censor it, or lose it. Only someone who knows your password can read it.

A group bundles several MediaIds into a paid subscription. You set a name, a price, a duration (in seconds), and the list of media IDs. Anyone can then subscribe by paying the price and gets read access to those media until the subscription expires.

• Use case: sell monthly access to a course, a photo pack, a private journal, a premium dataset.
• Who creates: only the contract owner.
• Who subscribes: anyone with a wallet and enough native token.
• What subscribers get: read access, not ownership. On expiry, access is revoked automatically.
• Payment: price + subFee goes to the owner or the configured payout address. No refund, no cancel once paid.

⚠️ Before subscribing: verify the group contains the media IDs you want, the price is fair, and you trust the owner. On-chain payment is final.

When you create a PermStorage contract, you choose a guardian (a second wallet you control, ideally on another device, in another location). If your main wallet is lost, stolen, or compromised, the guardian can transfer contract ownership to a new wallet — after a 7-day delay.

• Who acts: only the guardian. The current owner cannot block a recovery — this is intentional so a stolen wallet cannot freeze it.
• The 7-day delay: gives time to notice. If legitimate, the guardian completes it. If malicious, only the guardian themselves can cancel — so choose your guardian carefully.
• What changes: contract ownership (ability to create media, sell the contract, withdraw funds).
• What does NOT change: existing media stay on-chain. Their MediaId, content, and encryption are untouched.
• After a successful recovery: the child's recoveryWallet is reset to zero. The new owner must set a new guardian via the Orchestrator.

🛡️ Guardian rules: never share the guardian's key. Keep its seed phrase on paper, separately from your main wallet's. Use a different device and ideally a different location. The guardian is a backup, not a second daily wallet.

Groups are for paid, time-limited access. Access is the opposite: you grant a specific wallet permanent, free read access to your media — until you revoke it.

• Use case: let a friend, a family member, a lawyer, an accountant, or a trusted colleague read a file without paying and without an expiry date.
• How: call setAuthorizedReader(address) on your contract. One call grants access, a second call revokes it — it's a toggle per address.
• Who can grant/revoke: only the contract owner.
• What the reader needs: their own wallet connected, and the password. Access grants them the right to fetch the encrypted chunks — decryption still requires the password. So a friend you authorized cannot read your file unless you also give them the password separately (in person, over a call, on paper — never by email).
• What revoked means: their wallet can no longer call getMediaChunk. If they already downloaded the ciphertext and know the password, they keep their copy — but no new reads happen on-chain.
• Permanent: unlike a group subscription, access does not expire by itself. It only ends when you toggle it off.

💡 Think of it as handing someone a key to your safe room. You can give it, take it back, and if you never told them the lock combination, they can't open what's inside even with the key.

⚠️ Access is global to the contract, not per MediaId. When you authorize an address, it can read all media on that contract. If you need per-file access, either create a separate PermStorage contract for the sensitive file, or use a group restricted to specific MediaIds.

Every upload, every sale, every subscription, every write on-chain costs gas — a small fee paid in the chain's native token (ETH on Arbitrum, POL on Polygon, BNB on BSC, AVAX on Avalanche, etc.). The Gas tab shows live fee data so you know before you click.

• gasPrice — the current price per unit of gas on this chain.
• maxFeePerGas — the maximum you are willing to pay per unit (EIP-1559).
• maxPriorityFeePerGas — the tip to the validator for faster inclusion.
• What it means in practice: a single chunk of 20 KB can cost several million gas. Uploading a full file = one tx per chunk. The larger the file, the higher the total cost. Upload during low-traffic hours to save.

💡 Rules of thumb:

• On L2 chains (Arbitrum, Base, Optimism, Linea), gas is very cheap — cents per chunk.
• On L1 (Ethereum mainnet), gas is expensive — tens of dollars per chunk. Prefer L2.
• On Polygon, BSC, Avalanche, gas is usually cheap but can spike.
• If a chunk fails with "out of gas", the app automatically retries with a larger limit. If it fails with "insufficient funds", top up your wallet.

⚠️ Gas is not refundable if a transaction reverts for a reason other than the failure itself (e.g., a wrong password check on-chain — though this contract does not check passwords, so uploads don't fail on that). But other errors — wrong contract address, wrong guardian, insufficient PSTG token balance — will burn gas. Check the numbers twice before signing.

PSTG is the utility token of the PStorage#1 ecosystem. It is not a security, not an investment, and not sold by the author. It exists for one purpose: to let you create and use PermStorage contracts on-chain.

💡 How do you get PSTG?

• By creating a PermStorage contract — every deployment rewards you with 10 PSTG that land in your wallet as part of the deployment flow. This is the primary and normal way to acquire PSTG.
• Early access bonus (first 100 creators) — the first 100 wallets to deploy a PermStorage contract do not pay the deployment fee. They still receive the 10 PSTG reward. It is a thank-you for testing the system early.
• First 3 creators get a large amount — the very first three wallets to deploy receive a much larger PSTG allocation as a founding-contributor bonus. This is a one-time historical reward, already allocated.
• Activities organized by the author — contests, bounties, community events, bug reports, source translations, and other contributions may reward PSTG. Announcements are published on pstorage-num1.com.
• From the future enterprise — a company is being set up to formalize and expand these activities. It will offer paid enterprise services (larger storage, dedicated recovery, professional support, custom contracts) and may distribute PSTG as a loyalty or usage reward to its customers. This does not exist yet — it is coming.

🚫 What PSTG is NOT

• Not sold by the author, in any form, on any exchange, at any price. If someone offers you PSTG for money, it is not from the author.
• Not a promise of profit. Do not buy PSTG from third parties expecting it to go up. It is a utility token, not an investment product.
• Not required to read. You can read any media you have access to without holding PSTG. PSTG is needed to create and operate a PermStorage contract.
• Not tradable on exchanges as of today. The author has not listed it anywhere and does not endorse any listing.
• Not a guarantee of future value. Any future utility will be defined by the enterprise when it launches, if it launches, and will be documented at that time.

🌐 PSTG is deployed on 8 chains

🏢 What is coming in the next 3 months

The activities that started last year — the app, the contracts, the community experiments — will be formalized into an enterprise structure within the next 3 months. This enterprise will take over the serious side of the project: professional support, SLA-backed storage, dedicated recovery for enterprises, custom deployments, and a clear framework for using PSTG in a business context. The current app remains free and open. Announcements will be made on pstorage-num1.com.

• The files you choose to upload and how sensitive they are.
• The strength and storage of your password.
• The safety of your wallet, your private key, and your device.
• Any loss caused by user error, device failure, network issue, or bug in the software.

PStorage#1 is a tool. It does not work for any blockchain organization, exchange, or authority. It is an independent project. The author is not responsible for how you use it, what you store, or what happens to that data.
