This talk is targeted to people who are new to blockchain technologies, or interest in an systemic view of blockchain field, there will be plenty of offline reading materials and some homework!


Blockchain Technology Co-op program is a brand new program lead by ABC Blockchain community, a non-profit organization.

This program hope to create an environment to further general understanding of fundamental blockchain technology, starting with foundational layer technology, eg. data structure and consensus algorithm, and move upward towards real world applications and give pointers to future research. In each program, there will be 20-30 mins of technical lecture, given by Yucong Sun, with additional on-topic showcasing guest speakers from other blockchain companies. This program wish to inspire and share knowledge, participant are encouraged to engage in future discussions on our forum https://talk.abcer.world and with guest speakers. Some program also includes after-lecture workshop material and bonus!

Specifically, in the planned 4 program , the topics will be as following:

  1. Data structure of Bitcoin & Ethereum

Summary: In this program we will cover the most fundamental technologies used in Bitcoin and Ethereum, two most important blockchain exists today. Specifically , we will talk about UTXO/Account model, and how and why they enabled so-called distributed ledger. In additional , we will have guest speaker from Nervos , talking about their evolution of the UTXO model — Cell Model.

Speaker: Yucong Sun (https://linkedin.com/in/yucongsun )

Yucong is currently the program manager at ABC Blockchain Community for this program, previously he worked at Huobi, and Google, and as technical lead at several startups.

Guest speaker: Haichao Zhu (https://www.linkedin.com/in/haichao-zhu-4b703aba )

Haichao is a researcher at Nervos, focusing in both blockchain protocol and product design. Previously he was a researcher at Microsoft Research and Tokyo University.

Nervos is a layered network built to support the decentralized economy. The layer 1 protocol of the Nervos Network is the Common Knowledge Base (CKB), an open, public and Proof of Work based blockchain.

The CKB provides a turing-complete programming model (the cell model). Like smart contract platforms, CKB is versatile and stateful, though it is a state verification and storage system (like Bitcoin) rather than a computation platform. The CKB is not optimized for transaction throughput or performance, but like Bitcoin is designed to be maximally secure and censorship-resistant to serve as a decentralized custodian of value and crypto-assets. Learn more about the cell model.

Future Topics includes:
2. Consensus layer technologies.
3. VM & dApp Layer technologies.
4. dApp internals and optimizations , with applications categorizations.
