Casper the Friendly Finality Gadget is the consensus mechanism currently used by Ethereum, a type of PoS implementation.

Why does PBFT require two rounds of voting, and what is the role of the second vote?

Prelude: “Creative Thinking“ — Wang Yin I’ve noticed a phenomenon: when you say A is good, someone will say A is not as good as B, so A is not good.

First, here are two additional tips about investing in cryptocurrencies: Whether you are using Bitcoin, fiat currency, or another cryptocurrency as your base, it mainly depends on what you have on hand and which currency is easily accessible.

1.

I want to compare PoW and PoS from the perspective of entry barriers.

If you held some cryptocurrencies during the market downturn, the biggest significance of a bull market is that it allows your limited assets to gain in value.

In the past two months, I’ve been working remotely.

Probabilistic Encryption Functions In common symmetric encryption, one plaintext corresponds to one ciphertext.

Recently, I experienced something: I joined a startup and voluntarily resigned after working for two weeks.

Having gone through many interviews recently, I’ve noticed a common phenomenon: it’s hard to have a meaningful conversation with the interviewer.

Short Version If it issues coins, it’s a public chain; if it doesn’t, it’s a consortium chain.

Note: I have no intention of disrespecting the letter.

The role of a consensus mechanism is to ensure that the data across most nodes remains consistent.

This is an online web game: Pebbling Game.

Proof of Storage The most basic use of PDP (Provable Data Possession) for a file is to generate a corresponding TAG based on the file content, then send the file to another environment.

Previously, I didn’t understand how Filecoin manages disk space.

Lately, I’ve been troubled by the pain of poverty for a long time, but I don’t think trading cryptocurrencies is a good way to gain wealth.

The blockchain itself does not allow for random numbers because all nodes need to synchronize their results.

Have you ever wondered why the private key of Ethereum cannot be reverse-calculated from the account address?

Would you try your luck if you had a 1/100000000 chance to get rich?

Guess 2/3 of the Average is a classic game-theory exercise.

PORs (Proofs of Retrievability) and PDP were published in the same year, 2007.

What we now refer to as PDP generally refers to the PDP mentioned in the 2007 paper “Provable Data Possession at Untrusted Stores,” with Giuseppe Ateniese as the first author.

Of course, it’s not really a robot, just a simple script.

Recently, I’ve been feeling a bit lost, so I’m just writing randomly.

Steps Within a time window, a node will receive multiple validated blocks and randomly select one as its next block.

Yesterday, I encountered an issue where Ontology’s node stopped producing blocks.

1 A couple of days ago, I encountered a small problem: a Solidity smart contract exceeding 24 KB couldn’t be deployed on the Ethereum mainnet due to EVM’s code size limitation.

Web 3.0 Development Web 3.0 is a concept that has existed for several years and has become more popular with the promotion of blockchain technology.

On October 15, I wrote the following: Using Cloudflare’s DNS, I changed the subdomain gub from a CNAME pointing to GitBook to point to GitHub.

Blockchain is inherently a system that supports horizontal scaling, with exceptional node expansion capabilities.

Introduction The meaning of “egocentrism” is that for each person, the size of the world depends on how much of the world they can reach.

Is it possible for a blockchain to move beyond a purely linear structure into a graph-like data structure with multiple links—say, evolving from a singly linked list to a multi‑linked list?

Hash function A hash function maps data to its hash values.

In the Chinese context, there is no clear standard definition for “public chain” and “consortium chain.”

In Layer 2 of blockchain, there’s a scaling solution called State Channels, where it’s necessary to find the nearest routing node.

I originally didn’t want to mention blockchain specifically again.

How can one prove “I am me” in the world of the internet?

Can web technologies (HTML5, CSS3, JavaScript) achieve stunning 3D modeling or even 3D animation effects?

For a long time, blockchain seemed to lack a clear definition.

The Actor Model is a broad concept that was proposed in the last century.

Recently, I’ve seen several demo projects of management systems.

Rust is memory safe.

The first time I heard about Monad was at a Scala Meetup.

Recently, national leaders have publicly encouraged the research of blockchain technology, stating that blockchain should be used as a breakthrough for independent innovation of core technologies.

I once thought blockchain was a revolutionary and disruptive technology, alongside artificial intelligence and big data as the forefront of internet technology.

Rust is a language with complexity and application scenarios comparable to C++.
