nChain announces first implementation of Verifiable AI on Bitcoin

Published

on

LONDON, Sept. 19, 2024 /PRNewswire/ — Leading experts at nChain have identified and successfully tested ways in which the output of an AI system can be verified using a blockchain. This can be used to ensure the model operates according to its specifications, is free of critical bugs, and adheres to ethical standards such as fairness, transparency, and safety.  All without revealing proprietary information of the system – a major step in bringing trust and accountability to AI.  

nChain successfully demonstrated verifiable AI inference (processing queries) on Bitcoin showing the relevant transactions on the original protocol Bitcoin, Bitcoin Satoshi Vision Blockchain (BSV Blockchain). The transactions can be found on mainnet with corresponding generation code on Github

While this is a relatively new research area, and something nChain only recently started exploring, after having successfully implemented verifiable computation on Bitcoin the team challenged themselves to see if it could also apply this to machine learning.  

“Training is computation. Inference is computation. If you can do verifiable computation, then you can do verifiable training or verifiable inference,” says Dr. Hamid Attar, lead AI Researcher at nChain.  

The team trained a simple neural network on the MNIST dataset of images of hand-written digits. The model was then run on an input image, such as one provided by a user, and produced an output predicting which digit the input image represents. A cryptographic proof was generated to verify the output was indeed produced by running the model on the specified image while hiding all the information about the model. The proof was subsequently used to claim a small amount of bitcoin from the blockchain – in this case from the user. Here, Bitcoin not only provides a decentralised independent verification platform but also facilitates micro payment between a user and an AI model. 

With verifiable computation approach, nChain can prove cryptographically that an AI model is trained on the claim dataset. For example, it can be proven that a generative AI model is trained on a dataset that is known to have no bias.  More importantly, AI developers can prove that they did not tamper with the training dataset to train an AI model for malicious intentions. nChain can also prove that an output of an AI mode is obtained by running the specified AI model on the given input. For example, a piece of artwork can have a proof showing that it is generated by an AI model on a given prompt,  or as a paid user you can be sure that you are getting answers from ChatGPT4 not the free versions.  

nChain is proud to have successfully demonstrated verifiable inference on Bitcoin for the first time. The relevant transactions on the Bitcoin Satoshi Vision mainnet, and the code that generates them can be found on the zkScript GitHub repo

Notes to Editors: 

The main challenge is the fact that neural network works with floating points while zero-knowledge proof works with integers. Fortunately, back in 2017, Jacob et al. described an approach to quantise AI models without losing accuracy in an academic paper (https://openaccess.thecvf.com/content_cvpr_2018/papers/Jacob_Quantization_and_Training_CVPR_2018_paper.pdf). They needed this for migrating pre-trained AI models from powerful servers to less capable mobile devices. As part of the process, they convert floating points to integers to reduce the dimension of the model for efficiency. We managed to adapt the methodology to fit our purposes and maintain an accuracy above 90%. There are other techniques to quantise an AI model. For example, research groups such as ZAMA (link) are exploring quantisation-aware training where the model is trained with an awareness that the weights will be converted to integers later.  

To hide the model weights, we used a hash function and turned them into private inputs. Only the hash value of the weights is published. The computation circuit combines the AI model computation and the hash function used to verify the model wights with respect to the hash value. For proof generation, we use arkworks (link). Both the verification key and the proof are formatted in JSON files and passed to our zkScript tool to create locking script and unlocking script respectively. You can find this example use case here: nchain-innovation/zkscript.

Top-Notch B2B Sellers from South and Southeast Asia Crowned Champions at Alibaba.com’s KEL Award Grand Finale

Published

HO CHI MINH CITY, Vietnam, Nov. 15, 2024 /PRNewswire/ — Alibaba.com, a leading platform for global business-to-business (B2B) e-commerce, yesterday hosted the Key E-Commerce Leader Award (KEL) Grand Finale in Ho Chi Minh City, Vietnam. The event celebrated the achievements and contributions of outstanding B2B e-commerce sellers from across South and Southeast Asia, reflecting Alibaba.com’s commitment to fostering the growth of small and medium-sized enterprises (SMEs) in the global e-commerce sector.

The event brought together 10 top-notch e-commerce sellers from Vietnam, India, Pakistan, Thailand, Malaysia and Indonesia in one of the region’s most vibrant cities, Ho Chi Minh City. These exceptional sellers exemplify the transformative power of Alibaba.com’s platform, which enables local businesses to grow into global players by providing access to international markets and digital tools. The KEL Award spotlighted their achievements, resilience and leadership, inspiring other SMEs to embrace cross-border opportunities and reach international markets.

After hours of intense business case pitching by the top 10 finalists and careful deliberation by the judging panel, Alibaba.com announced the top 3 Key E-Commerce Leaders for KEL Award 2024 went to Ms. Xuan Hai Yen (Yanni), Deputy Director at Proline Vietnam Manufacture and Trading from Vietnam; Ms. Natasha Gogna, Managing Director of Shri Krishna International from India and Mr. Tayyub Hussnain, Founder of Norwich Streetwear from Pakistan. Additionally, the event awarded Mr. Tayyub Hussnain as the winner of the People’s Choice Award, determined by audience votes.

The judging panel included distinguished Alibaba.com leaders and experts: Mr. Shawn Yang (General Manager of Global Business Development at Alibaba.com), Mr. Roger Luo (Head of South and Southeast Asia at Alibaba.com), Ms. Ella Xie (Director of Global Business Development at Alibaba.com), and Ms. Savannah Zheng (CEO of CGCH & Awins).

Mr. Shawn Yang, General Manager of Global Business Development at Alibaba.com, shared: “Through the inspiring stories shared by the sellers at the KEL Award, Alibaba.com aims to motivate businesses across South and Southeast Asia to engage actively in the high-potential arena of global digital trade. For those who have already embarked on their digital trade journeys, we hope these success stories offer valuable insights and strategies for breakthrough, innovation, and diversified growth to succeed on a global scale.”

One such inspiring story comes from Ravin Sadh, founder of Conifer Handmades, whose journey demonstrates the immense potential of digital trade through Alibaba.com. He has spent the past two decades building a successful export business in the gifts and crafts industry without ever stepping into a traditional trade expo or needing to travel abroad. Since joining Alibaba.com in 1999, when the platform was newly established, Ravin has relied exclusively on it to reach customers worldwide. Today, 100% of Conifer Handmades’ business comes from Alibaba.com, with exports spanning over 35 countries. Focused on sustainable gift bags and crafts, Ravin’s business has grown exponentially through Alibaba.com’s digital platform, allowing him to connect with international buyers without the typical need for in-person networking or overseas travel. In fact, he only acquired a passport to attend the KEL Award Grand Finale, marking his first journey abroad as a testament to his commitment and success through Alibaba.com alone.

One of the 10 finalists, Tayyub Hussnain from Norwich Streetwear, shared a compelling story that underscores the transformative power of ambition and innovation in e-commerce. After graduating from Govt. Murray College in Sialkot in 2014, he embarked on his career with a modest monthly salary of 16,000 PKR. His entrepreneurial journey in the apparel industry was catalyzed when he received a laptop from the Chief Minister of Punjab, which introduced him to Alibaba.com. Through this platform, he secured his first major order of 770 pieces of clothing, an accomplishment that significantly boosted his confidence. This newfound assurance led Hussnain to leave his stable job and devote himself fully to building his business on Alibaba.com.

Xuan Hai Yen, Deputy Director of Proline Vietnam Manufacture and Trading, is a dynamic leader who has turned her family’s business into a multimillion-dollar enterprise with double-digit revenue growth over the past nine years. With 15 years of experience in the import-export and e-commerce sector, Yen exemplifies how resilience and a forward-thinking approach can drive transformative growth.

Yen took charge of the company during challenging times, crafting digital strategies to modernize operations and expand into global markets. Her vision to embrace digital solutions, particularly through Alibaba.com, helped revive the company, leading to an impressive 30% growth rate. Today, Proline exports a diverse range of products, including food bags, ESD anti-static bags and more. Under her leadership, Proline successfully expanded its reach to over 15 countries, including the U.S., UK, Malaysia, India, Thailand, Russia, Cambodia and Australia. Within just four months of joining Alibaba.com, the company secured its first U.S. order, a significant milestone in its growth journey. These success stories illustrate the transformative potential of e-commerce, with Alibaba.com serving as a vital growth engine, connecting businesses to the global market and maximizing their potential.
