Hey builder, it's another day in the blockchain space, and it's also a great day to dive deeper into blockchain. Today, we're going to share a thread on all the different types of consensus in the blockchain space.

1/With the interest in blockchain at an all-time high, more and more people are interested in investing and being part of the ecosystem. But to be an expert in blockchain, it's crucial to learn the basics. That's why today's thread will explain what consensus is and all the different types of consensus.

2/ What is Consensus in Blockchain?
Consensus ensures all nodes in a blockchain network agree on the state of the blockchain. It's crucial for maintaining integrity and security, preventing manipulation by any single node.

3/ Origins of Consensus
The concept comes from the Byzantine Generals problem in computer science. Introduced by Leslie Lamport, it involves generals needing to agree on a battle plan despite some being potential traitors. This problem was adapted by Satoshi Nakamoto for Bitcoin, addressing data consistency among network nodes.

Types of Consensus Mechanisms

4/ Proof of Work (PoW) - Used by Bitcoin Proof of Work is a consensus mechanism that ensures the integrity and security of a blockchain network by requiring miners to solve complex mathematical problems to validate transactions and create new blocks.

5/ Proof of Stake (PoS) - Used by Ethereum and Cardano, Proof of Stake (PoS) is a consensus mechanism where validators are selected based on the amount of cryptocurrency they own, called "stake." Validators put up their cryptocurrency as a stake to participate, and the one with the highest stake gets chosen to create a new block.

6/Proof of Authority (PoA) - Used by Vechain consensus like PoA use a few trusted validators, called "authorities," to verify transactions and add new blocks. These validators are known by their real identities and must act honestly or lose their status. PoA is efficient, uses little energy, and is fast, making it perfect for private blockchains where participants are known and trusted.

7/Proof of Personhood (PoP) is a consensus mechanism designed to ensure that each participant in a blockchain network is a unique human being, without revealing their real-world identity. It aims to prevent Sybil attacks, where a single entity creates multiple fake identities, by verifying the physical presence of individuals through in-person events or social networks.

8/Proof of History (PoH) is a consensus mechanism designed to ensure the security and efficiency of blockchain networks. It uses a cryptographic function called Verifiable Delay Function (VDF) to generate timestamps for each block in the blockchain, ensuring the immutability and authenticity of these timestamps.

9/This approach allows for fast finality, meaning that once a block is added to the blockchain, it is considered finalized and cannot be undone. PoH is used in the Solana blockchain network, which can process thousands of transactions per second, making it highly scalable and energy efficient.

10/Understanding diverse consensus mechanisms is crucial for anyone involved in blockchain. Each has unique strengths and applications, helping to shape the future of decentralized technologies. Whether you're a developer, investor, or enthusiast, knowing these mechanisms enriches your blockchain knowledge.

Acha que a escassez ajuda na valorização de um projeto? 🤔

1️⃣ Sim, geralmente contribui.
2️⃣ Não, não impacta.
3️⃣ Depende de outros fatores.
4️⃣ Impacta inicialmente, mas não é sustentável.

🔍 Resposta: 3️⃣ Depende de outros fatores. A escassez pode ser um fator que contribui para a valorização de um projeto, mas não é o único nem o mais importante.

É crucial analisar outros aspectos como:

Utilidade: O projeto oferece valor real aos usuários? Isso resolve um problema genuíno?
Tecnologia: A tecnologia subjacente é robusta, escalável e segura?
Equipe: A equipe por trás do projeto é especialista e confiável?
Comunidade: A comunidade está ativa e engajada?
Tokenomics: A estrutura do token é bem projetada e incentiva o uso sustentável?

Lembre-se: a escassez sem utilidade real é apenas especulação.

analisar o a thread em inglês onde explica sobre state machine

Tweat 1

Did you know that there's a crucial component in blockchain that nobody is talking about? 🤔 It's the backbone of the industry, and without it, the entire ecosystem would collapse. 🌐 I'm talking about the State Machine. 🤖 follow the thread : 🚀 #Blockchain #StateMachine

tweat 2

firs of all what is a state machine? a state machine is a fundamental computation model that can be implemented using both hardware and software. It is a simple yet powerful concept that determines its output based on both its current state and the input it receives

Tweat 3

Think of state machines like robots 🤖 They have different states (moods) and based on their input, they perform specific actions. Just like happy robots solve problems, state machines process transactions

Tweat 4

State machines are the foundation of many systems, not just blockchain, but also the computer industry as a whole. They provide a formal way to model and reason about complex systems, making them a crucial tool for designing and developing software and hardware.

Tweate 5

In the world of state machine are different types of states machines. those types are : Moore Machines,Mealy Machines,Harel Statecharts,Deterministic Finite-State Machines (DFSMs),Non-Deterministic Finite-State Machines (NDFSMs), and UML State Machines

Tweat 6

The main ones or the ones that are more discussed are Deterministic finite state machines(DFSMs) and Non-Determinitisc finite-state machines(NDFSMs) lets short their names to be more easy to digest.

Tweat 7

DFSMs Are state machines that guarantee a single output for each input, making them perfect for systems that require precise control. Think elevators, traffic lights, or vending machines - DFSMs keep things running smoothly #DFSM #StateMachines”

Tweat 8

NFSMs Unlike deterministic machines, NFSMs can handle multiple possible transitions from a given state on a given input symbol. This flexibility makes them powerful for modeling complex systems, but also introduces challenges in analysis and computation. #NFSM #StateMachines”

Tweat 9

Example of a state machine : Your coffee maker has 3 states: off, brewing, and ready. It starts off, turns on to brew, and completes brewing to become ready. Pressing off returns it to off. Simple example of state transitions in everyday devices

Tweat 10

Ok but now lets go to the fundemental question why is state machines important for blockchain lets say like this blockchain is basicly a state machine!! yes you heard a blockchain is state machine that make descisions based on the data that he has stored.

tweat 11

Blockchains are like specialized state machines on steroids they make decisions based on the data that is shared by a network making them the best way of tracking ownership or state of data. Each block represents a state change, and the chain reflects the complete history.

tweat 12

In the world technoligy state machines have very diferrent use cases not only in blockchain but all computer sector so maybe when you think about blockchain you should also think about states machines

Tweat 13

Wanna know more about state machines and blockchain come and be part of a group of developers who are learning how to. build a blockchain right know for free be part of our community of developers who are constatly learning
