Web3 is not a place. It is a rising tide of technology to lift all boats. It offers new ways to connect, create, and participate, with greater transparency, permanence, and global access.
Three ideas power the whole blockchain world. Tap each one to learn what it means, and why it matters for your capsule.

Concept 1 of 3
In most systems you use every day, one company controls your data and information. Instagram holds your photos. Google holds your documents. If they shut down, or delete your account, your things go with them.
In a decentralized system, information is stored across thousands of independent worldwide, powered by blockchain technology. That's what makes decentralized systems more permanent and resistant to alteration compared to their counterparts.
Concept 2 of 3
A blockchain is a public digital record, built and maintained by many nodes to create little histories stored in blocks that are chained together. Think of each block as a historian who compares their version of history with many others around the world to certify that something happened. If they all agree, the transaction is validated, proving the exact events that took place.
Every transaction (like a capsule being minted) is assigned a block and becomes part of a public history that anyone can view but no one person can change. These entries link in order, creating a transparent and unchangeable timeline.
Concept 3 of 3
Yes! Think of each blockchain like a different country that has its own rules, currency, communities, and strengths. You might have heard of blockchains like Solana, Ethereum, or Bitcoin. Each of these has its own strengths and characteristics.
This guide focuses on Solana because it is fast, affordable, and widely used for NFTs. Block Your Time is chain agnostic, so you can use whatever blockain you would like. If you are unsure, Solana is always a great place to start.
When you create your wallet, you'll be given the option to hold the keys to your wallet. If you select this option you'll be shown a list of 12 secret words. This is your seed phrase, and the only way to recover your wallet if you ever lose your phone or device.
We recommend you write these words down on paper and store them somewhere safe and offline. Anyone who has them has access to everything in your wallet.
Here's an example of what a seed phrase looks like. These are not your real words:
Every time capsule you mint lives on the blockchain, and is linked to your wallet. It is designed to last as long as the technology exists, and is nearly impossible to alter or take away.

Tap a term to learn
NFT: Non-Fungible Token
It sounds technical but the idea is simple. It's a unique digital record on the blockchain that proves a specific thing belongs to you. When you mint your time capsule, an NFT is created and linked to your wallet. It stores details like who created it, when, and the full history of where it's been. That record is public and traceable. The technology makes it verifiable by anyone, and extraordinarily difficult to alter or erase.
Mint
The act of putting or uploading something on the blockchain. When you mint your capsule, it becomes a record on a decentralized network. The record is designed to outlast any single platform, company, or decision.
Before anything else, reflect about the type of memories you wish to always remember. The format can be a photo, collage, letter, video, or anything your imagination can dream up. Just make sure to save the file in a format you can upload.
Not sure what to make?
One file that actually means something right now.
This is a record of who you are in 2026, so choose something real.
