Numbers Protocol (NUM)

The 5 Layers of Digital Trust in 2025

You’re trusting everything you see online without thinking

Every image, every video, every “leaked” screenshot, you have zero proof any of it is real.

If you want to understand how digital trust actually works, there are only five layers that matter.

@numbersprotocol is the only platform that covers all layers.

…
Here’s the breakdown so you actually get it:

▻ Layer 1: Capture Integrity
Was the photo/video really taken at that time and place? The app locks the sensor data so fake timestamps won’t work.

▻ Layer 2: Content Integrity
If the file is edited or altered, the app’s fingerprint won’t match anymore.

▻ Layer 3: Chain of Custody
Every time the file is shared or changed, it’s recorded on a blockchain like a digital passport.

▻ Layer 4: Contextual Integrity
Attach sounds or nearby info to prove what was happening when the media was captured.

▻ Layer 5: Future-Proof Evolution (ERC-7053)
If you edit or remix the media later, it still keeps the original history using ERC-7053.

…
Now the part nobody likes to admit:
Instagram, TikTok, and even X give you Layer 0.
The only guarantee is “someone uploaded this. That’s not trust.

Numbers Protocol actually solves the full stack with open-source tools you can use right now.
- Journalists use it to protect sources.
- Creators use it to prove ownership.
- Courts and election monitors use it because “trust me” isn’t proof anymore.

You don’t have to guess what’s real, but you can verify it.

大多数人认为“区块链是不可变的，所以无法更新任何内容”。

确实，但这并非全部

有一个新标准正在改变我们在链上处理数字媒体的方式：EIP-7053。

那么，EIP-7053 是什么？
它是一个面向数字媒体的开放索引标准。
每个文件、内容、照片都会获得一个内容 ID，之后的每次更新都会生成一个绑定到同一 ID 的新的链上提交。

﹍
▻ 它在 @numbersprotocol 上是如何运作的 ?
Numbers 使用 EIP-7053 作为其溯源系统的骨干。
当照片或视频进入网络时：
‣ 它会获得一个内容指纹（CID/NID）
‣ Numbers 应用或 SDK 使用 7053 提交函数将该 ID 提交到链上
‣ 该提交成为该资产链上历史的第一条记录
‣ 任何未来的更新或元数据都会作为新的提交追加，而不会改写过去

你将拥有一条不可变的真实性链，但它仍足够灵活，可追踪版本、编辑或创建证明。

▻ 这对 web3 有何意义？
我们终于拥有了一个共享的、开放的媒体溯源标准。任何链都可以采用它，任何项目都可以基于它构建。

a single way for web3 to track where digital media comes from and how it changes over time.

对于创作者、记者、AI 数据集、NFT 平台或任何需要可信媒体的应用来说：
EIP-7053 为你提供了一种证明来源、展示历史、检测篡改并在网络间保持资产可迁移的方法。

﹍
我们每天都被 AI 生成的内容、编辑和转发的素材包围。

因此，拥有真实的溯源现在变得至关重要。
EIP-7053 使我们更接近一个可以信任所见内容来源的 web3。
