The true meaning of blockchain is that it provides humanity with a unified “truth” algorithm for the first time.

We learned that on September 12th, during TOKEN2049 in Singapore, at the “Web3 Asian Power” summit co-hosted by 1783DAO and BoLianCaiJing, Sunny Feng Han, a Columbia University exchange PhD student & visiting scholar, former blockchain consultant for Huawei’s Central Research Institute, and co-founder of Elastos, shared his forward-looking vision for the blockchain industry, emphasizing the importance of a unified cognitive system and intelligent algorithms and the key role of BTC blockchain in achieving this goal.

Sunny Feng Han first highlighted the tremendous potential of blockchain technology in creating a unified cognitive system and intelligent algorithm. The immense success of ChatGPT in the AI field indicates that the unification of intelligent algorithms across disciplines is entirely achievable. Professor Ben Koo and Sunny Feng Han began offering a course titled “Beyond the discipline's Foundations of Cognition” at Tsinghua University as early as 2015.

He believes that by leveraging the development of BTC L2, and basing it on BTC timestamps, it’s possible to unify the algorithmic consensus and cognitive rules of smart contracts across various public chains, breaking the barriers of asset and transaction rights and recognitions among different public chains. This innovation in unifying the digital asset and transaction rights recognition system will not only be a technical advancement but will also bring revolutionary changes to the entire human economic and social system.

Sunny Feng Han pointed out that a key characteristic of the blockchain revolution is its ability to provide a “timestamp” for digital asset transactions. The Bitcoin network has ensured that no counterfeit coins have been produced over the past decade thanks to this innovative mechanism, an achievement no other currency system in human history has accomplished. This is also the foundational assurance for Bitcoin’s market cap surpassing the volume of gold by 2025 because it guarantees the absolute correctness of the causal order of asset transactions.

This technical innovation and POW mechanism will play a pivotal role in realizing a unified public chain rights recognition system in the future. Elastos, with its mechanism designed by Jihan Wu (Co founder of BitMain)for merge mining with Bitcoin, currently ranks second in terms of Hash power in the POW system and is naturally a strong supporter of the BeL2 test network.

He also shared the technical stack that the BeL2 team is researching based on the results from the MIT Digital Currency Initiative. This technology uses zero-knowledge proof technology to unify the “timestamps” of different public chains and smart contracts, potentially enabling seamless connections between the Bitcoin public chain and other smart contracts. This means that different blockchains can share a unified “timestamp” from the Bitcoin network, and a unified asset rights and transaction system spanning Bitcoin and Ethereum public chains could potentially be established.

Sunny Feng Han believes that the true significance of blockchain is that it offers humanity a unified “truth” algorithm for the first time. In the past, people had to rely on various authorities to determine what is true and correct, but blockchain, through its distributed computing, timestamps, and consensus mechanism, has established the authenticity and accuracy of transactions and assets as an indisputable computational standard and mechanism. This has profound implications for eliminating false narratives and deceptive schemes like “Point at a Deer, Call it a Horse”.[1]

“Point at a Deer Call it a Horse” is based on the Chinese idiom “Zhi Lu Wei Ma 指鹿为马” — to confuse right and wrong, to distort reality through misrepresentation, to deceive. Historically, it dates back to Zhao Gao, a prime minister of the Qin Dynasty who, in 207 BCE, used dissent to test the court, gauging their loyalty by presenting the emperor with a deer and saying, “This is a horse.” This metaphor for the curatorial rationale has a clear presence in all of the works on display, further reinforcing the show’s notion of “unreal socialism.”
