Did you enjoy the last episode, What is Token Model- Part 2? Today we are going to talk about a new model, the Voting Model.

Due to the prolonged COVID-19, more listed companies are adopting electronic voting. A total of 184 companies used electronic voting for general shareholders’ meetings in 2021 compared to 2020, which is a 27.9% increased rate from the past year.

Did you enjoy reading last week’s What is Token Model — Part 1? Last time, we looked into the difference between tokens and coins and the standard token, ERC-20. If you missed the last article, please read it first and move on! Today, we are going to talk about what needs to be solved on the ERC-20 token and the token economy.

First, Ethereum Network, the mainnet of ERC-20 today, is attempting to change from Proof-of-Work (PoW) to Proof-of-Stake (PoS) to…


In this episode, we will talk about Token Model continuing from the last episode, [What is Digital Asset Model?].

Hello, this is Team Protocon Network.

What comes to your mind first when you think of electronic documents? Unlike paper documents, electronic documents may seem distant, but they are easily found in everyday life. An example of the electronic document is an electronic receipt. I’m sure you’ve received it at least once because quite a few places, including Starbucks, are now issuing electronic receipts instead of paper receipts! As such, electronic documents are already being commercialized. In particular, the most active electronic document management industry is the financial industry, with Bank of America that went paperless since 2018.

Hello. This is team Protocon Network. In the last episode, we talked about the definition of Protocon and unresolved problems in the blockchain industry. If you haven’t read the first article yet or would like to learn more about the Protocon Network, please check out the first episode <What is Protocon?>.

Today, let’s talk about the ways Protocon found to achieve a safer data processing and development environment. Protocon Network presents a new framework called a ‘Model’ that adds security and operational policies to Ethereum’s smart contract structure.

Since the COVID-19 Pandemic, existing economic and consumption patterns have changed to a new paradigm called ‘non-face-to-face and digital transformation’. The advantage of digital transformation is that there are no spatial and time constraints, and a representative example of this is the ‘smart work’. It is better known as a flexible work system(flextime) in Korea, and it is a system introduced by Samsung Electronics, Naver, and Woowa Brothers meaning that working hours can be adjusted flexibly.
