这个想法2021年的时候 OE1GAQ 提出过 https://www.geraldartner.at/files/Artner2021QSP_English.pdf 现在 Arbitrum 这种 L2 可以解决文章中最大的 Gas 费昂贵问题。但是我觉得还是有几个难点： 1. 社区接受度的问题。至今都有 HAM 不接受数字模式，不接受 eQSL。那么到底有多少人会接受这种 NFT 形式？如果接受度很小，那只能是圈地自萌的小众文化。价值可能不如交换字母饼干 QSL，最起码还能吃。 2. 需要用户了解加密货币相关概念。这是一种跨圈的、有一定技术门槛的、对传统无线电通联毫无意义的行为。那么与其花时间了解他，大家可能宁愿花时间和大佬沟通通联经验、怎么拉端馈噪音小。 3. 主流奖项是否接受 NFT 作为有效凭证。很多人 QSL 是为了拿奖的，除非 ARRL 认可 NFT QSL 不然毫无助力。如果不为了拿奖也完全可以 eQSL，甚至还不用花钱。那么为什么要花钱（即使 L2 Gas 可低至几分钱）去做一个费力不讨好的事情。 4. 法律法规相关问题。购买 NFT 后常见的储存位置是冷钱包或者 IPFS，前者与我国政策向左，后者的由于 QSL 只对通联双方有价值所以储存节点少访问速度很慢，且官方网关已经被我国屏蔽。现在已经有很多人用相册或者扫描的方式来储存 QSL 卡片了。从众多只想通联和拿奖的 HAM 眼里，QSL NFT 可能和换一个加密相册或者加密文件夹区别不大。

感觉完全没有必要现在电邮发eQSL都有人拒绝的而且这玩意和数字藏品属性完全不一样

个人认为技术上实现不难，但是需求人数不多。纸质卡都不给地址，更别提NFT QSL了

好想法！虽然会有很多人对这个不感冒，但是看起来确实挺炫酷

只能换卡不太行，但如果是主要提供类似lotw的日志匹配和发奖状功能，换卡只作为填头就比较实用了。我曾经想过类似的东西，但由于对加密和零知识证明方面了解不够深入，无法实现让“矿工”在日志加密的状态下匹配通联时间于是就放弃了。

社区内出现了几次这样类似内容的讨论了。很简单，如果你自己认为有价值，或者能学到东西，那么就去做。按 MVP 的模式，先做出来，简单实现。推广、求证的时候，你可以不用吧重点放在自己的所在的土壤里，这样你就解决了很多的烦恼。等到土壤外的人，有一批人认可你的方案，这事情就算成了。

感覺沒什麼用部分老ham都不接受eqsl，年輕人可能用多一點

少说话多做事，等成品出来后市场会给出答案😆

Idea: Building a QSL NFT (a card exchange platform on Ethereum L2 blockchain)

pyxmr2025

For a long time, QSL cards have served as an important medium for confirming communication and fostering friendship, carrying the precious memories of the ham radio community. To overcome the physical limitations of traditional QSL cards in collecting, preserving, verifying, and global circulation, I propose building a blockchain-based QSL card NFT (Non-Fungible Token) exchange platform. I invite fellow hams to discuss this further.

(Note: If you are unfamiliar with the concept of NFTs, please refer to this introduction:)https://baike.baidu.com/item/NFT/56358612）

Blockchain technologyDecentralization, immutability, and uniquenessFeatures that closely align with the need for QSL cards as proof of communication. Converting communication records into digital cards in the form of NFTs can enable:
✅ Permanent record: Key data such as call sign, time, frequency band, and signal report are permanently stored on the blockchain, making them publicly verifiable and tamper-proof.
✅ Global Connect: Sending QSL cards internationally is faster and much cheaper than international postage.
✅ Empowering creativityCombine community art creation to generate digital collectibles that have both commemorative value and visual appeal, thereby enriching the forms of amateur radio culture.

▍Core Function Ideas for the Platform
Users can upload images (such as homemade cards or photos of their radio room) or use templates, combined with 通联 data, to create QSL cards.Layer 2 chains with low gas fees (such as Polygon) Create exclusive NFT QSL cards. Smart contracts will automatically associate metadata, ensuring the uniqueness of each card.

⚠️ Cost Considerations: A small gas fee (similar to postage) must be paid each time an NFT is created or sent.https://zhuanlan.zhihu.com/p/1939035712965047871。

We welcome discussions with other stations regarding technical implementation, user experience, or ecosystem design! 73!

Long ago, QSL cards have been an important carrier for confirming communication and fostering friendship, carrying many of our cherished memories. I would like to build a blockchain-based QSL card NFT (Non-Fungible Token) exchange platform, and I hope to discuss this with my fellow operators.

First, you can learn what NFTs are. Here's a link:NFT

Traditional physical QSL cards have certain limitations in terms of collection, preservation, verification, and global circulation. The decentralized, tamper-proof, and unique characteristics of blockchain technology are well-suited to the need for QSL cards as a universal proof of communication. By minting each valuable communication record as an NFT-based digital QSL card, we can:
Permanent Record: Communication records (such as call number, time, frequency band, signal report, etc.) will be permanently stored on the blockchain, making them easily searchable and tamper-proof.
Convenient exchange: Ham radio operators around the world can quickly and cost-effectively exchange and display QSL cards.
Sparking Creativity: By combining community art creation, unique digital collectibles with aesthetic appeal and commemorative value can be generated, enriching the forms of amateur radio culture.

Initial concepts and core functions
NFT QSL card generation: By uploading relevant images related to Tonglian (e.g., self-made cards, screenshots of Tonglian, photos of the radio room), or using templates, combined with Tonglian data, generate exclusive NFT QSL cards on a Layer2 (or sidechain) network (such as Polygon) through smart contracts. This reduces Gas fees, making creation and exchange more feasible.

Please note: Each time an NFT is created, the corresponding transaction fee must be paid.Gas bill(Similar to postage)

Welcome to everyone participating in this discussion.

I don't think it's necessary at all. Nowadays, many people refuse to accept eQSLs sent via email, and this doesn't have anything to do with digital collectibles.

BG2GGH

Personally, I believe that from a technical standpoint, it's not difficult to implement. However, the demand for this technology is relatively low.
They don't even accept paper QSL cards, let alone NFT QSLs.

BI1XJT

That's a great idea! While many people might not be impressed, it certainly looks very cool.

It's not very practical to only replace cards, but if the primary function is similar to LOTW (Logbook of The World) for logging and awarding certificates, then replacing the card as a simple input method would be more useful.
I had considered something similar, but due to my lack of in-depth knowledge about cryptography and zero-knowledge proofs, I was unable to implement a system where "miners" could match timestamps even when the logs were encrypted. As a result, I abandoned the idea.

BG5UWQ

There have been several similar discussions within the community.

It's simple: if you believe it's worth doing, or if you can learn something from it, then go ahead and do it. Following the MVP (Minimum Viable Product) approach, start with a basic implementation.

When promoting or seeking validation, you don't need to focus solely on your own environment. This will help resolve many of the issues. Once a group of people outside your immediate circle recognize and approve your solution, that's when it becomes successful.

VR2WBZ

I don't think it's very useful.
Some older hams don't accept EQSL; younger people may use it more often.

BA4JKS

That's a very interesting idea.👍

BG5VCU-VK2VCU-AK6CU

Focus on action rather than talking; the market will provide feedback once the product is complete.😆

BA4JKS

I tried it out, and I think it's pretty good.
