Pi Network’s open mainnet went live at 8:00 UTC on 20 February 2025, and since then the real question for most Pioneers has not been “is it live?” but “is our Pi live?” Your balance only becomes transferable after you pass KYC (identity verification), migrate it from the mining app to the blockchain, and clear any lockups on it. Each of those steps has its own queue, its own failure modes and, as of 7 October 2026, its own open bugs.
This page is the timeline and the mechanics in one place. It covers what the mainnet actually is, how KYC works and why it fails, how migration and lockups behave, what changed in September 2026, and what all of it means if your goal is to eventually sell. If you only care about the selling part, jump to the how to sell Pi coin guide once you have read the section on what counts as “transferable” below.
What “mainnet” means for Pi
A mainnet is the live blockchain where balances are real and transferable, as opposed to a testnet used for experiments. Pi ran in phases. The Enclosed Network began in December 2021, according to Pi’s own posts: the blockchain existed, but a firewall kept it from connecting to outside networks, so Pi could not be deposited on exchanges or sent to outside wallets. On 20 February 2025 the firewall was removed. That is the “Open Network” or “open mainnet” you see in headlines.
Pi said it would open only once three conditions were met, and in its launch announcement it claimed all three: 15 million identity-verified Pioneers (it reported 19 million), 10 million mainnet migrations (it reported 10.14 million), and 100 or more mainnet-ready apps. Those user numbers are Pi’s own and have not been independently audited. Treat them as claims, not measurements.
Under the hood Pi uses the Stellar Consensus Protocol, a design where nodes agree on transactions through overlapping trust groups rather than proof of work. Pi’s node software tracks Stellar’s protocol versions, which is why you will see “v19”, “v20”, “v23” and now “v28” in Pi’s upgrade posts. If you want the full beginner picture, what is Pi coin covers it. Here we only need one point: the mainnet being open does not mean your coins are on it.
The timeline, with dates you can check
Below is the sequence that matters, drawn from Pi’s own blog wherever possible. Where a date comes from media or a community account instead, the row says so.
| Date | What happened | Why it matters |
|---|---|---|
| Dec 2021 | Enclosed Network phase begins (per Pi) | Blockchain live, but behind a firewall |
| 2024 to 14 Mar 2025 | Grace period for KYC and migration, extended several times (30 Nov 2024, 28 Feb 2025, final deadline 14 Mar 2025 08:00 UTC) | Unverified balances older than six months risked being forfeited |
| 20 Feb 2025 | Open Network launches, 08:00 UTC | External exchanges and wallets can connect |
| 23 Oct 2025 | Pi says system checks let 3.36M tentatively verified Pioneers pass KYC fully | Biggest single clearing of the KYC backlog |
| 30 Jan 2026 | KYC and migration update; palm-print authentication explored | Pi starts testing biometrics beyond face liveness |
| Feb to Mar 2026 | Mainnet upgrades v19.6, v19.9, v20.2, then protocol 20 | Pi calls protocol 20 the foundation for smart contracts |
| 14 Mar 2026 | Pi Day: second migrations begin, first KYC validator rewards, Launchpad testnet MVP | Referral and team bonuses become migratable |
| 26 Mar 2026 | 119,000+ Pioneers have completed second migrations; 2FA becomes required | Wallet security step is now a gate for migration |
| 15 to 22 Jul 2026 | Protocol v25 and an app menu redesign; Banxa removed from in-app wallet creation | Fast-Track KYC replaces the old fiat route into a wallet |
| 17 Sep 2026 | 417,000+ duplicate flags cleared; about 497,000 Fast-Track wallets cannot claim for lack of gas | Newest and messiest fix, see below |
| 30 Sep 2026 | Pi Core Team says it will explore Pioneer rewards and payments with Open Standard, issuer of the OUSD stablecoin | Exploration only, no integration details given |
| 13 and 16 Oct 2026 | Reported node upgrade deadline and “Protocol 28” activation (UNCONFIRMED: community-relayed) | Pi’s node page confirms only that mainnet nodes must upgrade to v28 |
Two caveats. Pi’s blog is the only primary source for Pi-side events, and several 2026 items (such as the protocol 23 activation in May) were reported by media without a Pi page we could locate, so we left them out of the table. And the last row is a good example of how Pi news spreads: a plausible-looking date list circulates, a news site repeats it with a disclaimer, and by the time it reaches social media the disclaimer is gone. Until Pi posts it, treat 13 and 16 October as rumor.
KYC: what it asks and why it fails
KYC stands for “know your customer”, the ID check banks and exchanges use. Pi’s version has its own twist. According to Pi’s FAQ, it is a native, decentralized system that validates an account as a real individual against a government-issued ID, and it is required before mobile-mined Pi can reach the mainnet. The point, in Pi’s words, is to stop bad actors piling up Pi through fake accounts. That aim is reasonable. The execution has been the slow part.
In practice you submit ID documents and a liveness check (a short video proving you are a live person). Pi names Yoti as one liveness provider. Over 2025 and 2026 the Core Team added an AI-assisted standard KYC flow, which it says cut the workload for human validators by about half, a Fast-Track route, and a one-month palm-print trial for Pioneers who needed repeated liveness checks. Ordinary users also act as validators: Pi reported paying 26.57 million Pi to 1,094,680 validators for 526,970,631 validations (about 0.0504 Pi each) in the first reward round.
Why does KYC fail? From the 17 September 2026 update and earlier posts, the recurring causes are:
- Possible duplicate flag. The system suspected one person had more than one account. This was the big one (more than 417,000 people re-cleared on 17 September).
- Liveness failures on older phones. Pi says it widened the compatibility logic for lower-spec devices.
- Video processing errors. Pi says machine-learning fixes reduced stalled applications.
- Document problems. For example, Indonesian users rejected over an invalid KIA ID can now resubmit with supported alternatives. Yoti users with missing liveness data can also resubmit.
Most people who give up do so at the “pending” stage, not at the rejection stage, because a stalled review gives no clear next action. If that is you, open the KYC section of the app: Pi says it shows whether you are eligible to resubmit after the September fixes.
Pi’s pages describe KYC with no fee. Messages offering “priority KYC”, “migration help” or “wallet sync” for a payment or your passphrase are not from the Pi Core Team. The Core Team has said it will never ask for your password or wallet passphrase. The paid product PiVerify is a KYC-as-a-service tool for third-party businesses, not for Pioneers. More on this in is Pi coin legit.
Migration: from the app balance to the blockchain
Mining in the app produces a number on a screen. Migration is the process that turns that number into an actual balance on the mainnet in a wallet you control. Pi’s FAQ is blunt: unverified and unmigrated Pi in the mobile app is not transferable.
The order is: pass KYC, complete the Mainnet Checklist in the app (which includes creating the Pi Wallet), then wait for your migration to process. Migration has run in batches. The first migration moves your transferable balance. Pi’s Pi Day 2026 announcement began second migrations, which bring across things like referral mining bonuses from team members who have completed KYC. By 26 March 2026 more than 119,000 Pioneers had completed a second migration. Pi also said it would move to “ongoing periodic migrations” with the frequency still to be decided. Since 26 March, 2FA on the Pi Wallet (step 3 of the checklist) is required, and some accounts need a trusted email address added.
Your wallet passphrase is generated on your phone and never sent to Pi’s servers. That is the good news for security and the bad news for forgetfulness: Pi cannot recover it. The practical side is in the Pi Wallet guide.
The 17 September 2026 gas-fee snag
The latest hiccup is worth understanding because it hits exactly the people Pi tried to help. Pioneers who got their wallet through the Fast-Track process could not claim their migrated balance because the wallet held no Pi to pay the network (gas) fee for the claim. Pi put the number at about 497,000 and promised a patch “within a week” in its 17 September post. We could not find a follow-up post confirming the fix by 7 October 2026, so if you are in this group, check the app and the Pi blog before you try again. Pi’s own advice was to retry claiming if earlier attempts failed on insufficient gas.
Lockups: why Pi can be locked
“Locked Pi” can mean three different things, and mixing them up causes most of the confusion in forums.
First, not-yet-transferable Pi: your balance exists in the app but KYC or migration is incomplete. This is not really a lockup, just a queue.
Second, bonus Pi that unlocks gradually. Pi’s FAQ says more balance becomes transferable as members of your Security Circle pass KYC. If your teammates never verify, part of that balance may never unlock.
Third, voluntary lockups. Pi lets Pioneers commit part of their balance to a lockup of their choosing, and rewards longer commitments with a higher mining rate. That one is a trade you make with yourself: a bigger mining boost in exchange for not being able to sell that Pi until the lock expires.
Beyond those, on-chain analytics firms track large locked balances and report periodic unlocks. Figures such as roughly 190 million PI unlocked in December 2025 and about 239.5 million over a 30-day window from early April 2026 come from third-party trackers, not from Pi. Pi has not published an official unlock schedule on any page we could find, so we will not give you unlock dates. If a site promises “your unlock date” or sells an unlock service, it is guessing or scamming.
What this means if you want to sell
Selling only works on a transferable balance in a mainnet wallet. Everything else in the app is a promise, not a coin. The path is: KYC passed, migration done, 2FA set up, enough Pi in the wallet to cover a small network fee, then a transfer to an exchange deposit address (with the memo if the exchange requires one) and a sell order. Each step is covered in how to sell Pi coin, and the venues are compared in Pi coin exchanges.
Two realities worth stating plainly. Liquidity is thin: CoinGecko showed about $7.5 million in 24-hour volume on 7 October 2026 against a market cap near $0.94 billion, so a large sell can move the price. And the price itself is well below its 2025 peak (about $0.083 on 7 October 2026 versus a $2.99 high on 26 February 2025). The Pi coin price page has the live figures.
Each wave of KYC and migration changes how much Pi can actually be sold. News of a big batch clearing can be read two ways: more users with access, or more supply that could hit exchanges. Which one dominates depends on demand at the time. Nobody, including us, can tell you in advance.
What to do next, and what we could not confirm
If you have not started, begin with the in-app Mainnet Checklist and do not pay anyone. If you are stuck on a duplicate flag, check the KYC section for a resubmission option. If you are a Fast-Track wallet holder, wait for Pi’s confirmation of the gas fix and then retry. If you are thinking about running a node, watch Pi’s node page rather than social posts: it states that every mainnet node must upgrade to v28.
What we could not verify: the exact total of migrated Pi (Pi’s last primary figure is 15.8 million migrants at the end of 2025), the date Pi first published the 2019 launch details, whether smart contracts are live on the mainnet (Pi’s own blog describes them as testnet features through September 2026), and independent audits of any user count. If you want a risk-weighted view of the project as a whole, is Pi coin legit goes through the evidence both ways. This page is information, not financial advice.
