Por que comprar Ethereum(ETH)?

O que é Ethereum? A plataforma para contratos inteligentes e aplicativos descentralizados
O Ethereum (ETH), fundado por Vitalik Buterin em 2015, é a primeira blockchain pública do mundo que suporta contratos inteligentes. O Ethereum permite que os desenvolvedores criem aplicativos descentralizados (DApps), protocolos DeFi, NFTs e muito mais, impulsionando um crescimento explosivo no ecossistema Web3. Ether (ETH) é o token nativo da rede Ethereum.
Como funciona o Ethereum? EVM, taxas de gas e consenso
O Ethereum depende de nós distribuídos, com cada transação exigindo ETH como uma “taxa de gas”. Os contratos inteligentes executam automaticamente acordos condicionais, amplamente usados em finanças, jogos, cadeias de suprimentos e muito mais. Inicialmente usando o PoW, o Ethereum concluiu a atualização “The Merge” em 2022, fazendo a transição completa para o Proof of Stake (PoS), reduzindo o consumo de energia em mais de 99% e aumentando a sustentabilidade e a segurança.
Mecanismo de abastecimento e EIP-1559
O Ethereum não tem limite de oferta fixo, mas desde o EIP-1559, uma parte da ETH é queimada em cada transação, ajudando a reduzir a pressão inflacionária. A ETH é essencial para pagar taxas de gas, recompensas de staking e participação na governança, com a demanda crescendo junto com a expansão do ecossistema.
Ecossistema e casos de uso
Os padrões ERC-20 e ERC-721 do Ethereum impulsionaram o surgimento de DeFi e NFTs, dando origem a projetos como Uniswap, Aave e OpenSea. A Ethereum Virtual Machine (EVM) fornece um ambiente de programação flexível, promovendo a interoperabilidade entre cadeias e soluções de escalonamento de camada 2 (por exemplo, Rollups, Sharding).
Razões e riscos para investir no Ethereum
Web3 e infraestrutura de contrato inteligente: ETH é o principal ativo para DeFi, NFT, DAO e outros aplicativos inovadores. Atualizações técnicas e crescimento do ecossistema: a transição PoS e o EIP-1559 aprimoram o desempenho da rede e a captura de valor. Alta liquidez e aceitação geral: a ETH é negociada globalmente, perdendo apenas para o Bitcoin em capitalização de mercado. Riscos: congestionamento da rede, altas taxas de gas, concorrência de blockchains emergentes (por exemplo, Solana, Avalanche) e incerteza regulatória.
Visões céticas e perspectivas alternativas
Embora o ecossistema do Ethereum seja vasto, os problemas de escalabilidade e taxas persistem. A falha em resolvê-los pode fazer com que sejam superados por blockchains mais novos e de alto desempenho. Os investidores devem monitorar o progresso tecnológico e as mudanças no ecossistema.

Recently, I was thinking about how blockchain actually works, and I came across the topic of txid, or transaction identifiers. This is something every cryptocurrency user should know, but not everyone understands how it works.
A txid is essentially a unique code assigned to each transaction on the blockchain network. Think of it as a reference number for your transfers. When you send funds, the system generates such an identifier through complex cryptographic hashing, ensuring that each txid is unique and impossible to counterfeit.
What interested me is the scale. Data from analytical platforms show that millions of transactions are processed daily on Bitcoin and Ethereum. Each of them has its own unique txid, allowing full tracking and verification. For example, when someone makes a significant transfer, its txid remains in the network as an immutable record.
The history of this solution dates back to 2009, when Bitcoin appeared. Satoshi Nakamoto, the project's creator, introduced this system as a fundamental element for transparency and security. Since then, txid has become a standard in all blockchain implementations.
What is it used for in practice? Primarily for tracking. You can enter the txid into a blockchain explorer and see exactly what happened to your transaction. This is invaluable for audits and compliance with regulatory requirements. Organizations use txid for transparent monitoring of money flows. If something goes wrong, the txid helps resolve issues and settle disputes.
Newer trends show that some platforms add additional metadata to txid, providing richer information about the transaction. There is also increasing work on interoperability between networks, where txid is used to connect transactions across different blockchains.
On major trading platforms, txid is a standard tool. Users can verify their deposits and withdrawals by entering the txid into an explorer. This provides instant confirmation and full transparency.
In summary, txid is not just a technical detail. It is the foundation of trust in the blockchain ecosystem. Without it, we wouldn't have confidence that our transactions are secure and permanent. As blockchain develops, the role of txid will only grow, and its applications will expand to more industries and markets.

Honestly, Ilya Polosukhin's story is a classic example of how one person can influence an entire industry. When I look at his journey, it's clear that he didn't just participate in creating technologies, but truly redefined them.
Polosukhin started at Google, where he worked for seven years on TensorFlow. This is not just a machine learning library — it's a tool that made AI accessible to everyone. When TensorFlow Lite was released in 2017, it was a big deal. Suddenly, researchers and developers around the world gained a powerful open-source tool. It was exactly what the community needed.
But Polosukhin didn't stop there. Together with his team, he created NEAR Protocol — and this is where the truly interesting part begins. In 2020, they launched the mainnet, and it was not just another blockchain. NEAR was designed with a focus on user-friendliness and scalability. That is, not technical complexity for its own sake, but real solutions to problems.
Then, in 2021, Aurora appeared — a solution for scaling Ethereum based on NEAR. It was a smart move because many developers already knew Ethereum, and Aurora allowed them to work in a faster and cheaper ecosystem.
What impresses me about Ilya Polosukhin's approach is its consistency. Whether it's TensorFlow or NEAR, the same idea is visible everywhere: to make cutting-edge technologies accessible, not elitist. This has influenced the entire industry. Now other projects are also thinking about user experience, scalability, and openness.
Polosukhin has shown that blockchain can be not only for specialists. DeFi applications, decentralized services — all of this has become easier to build thanks to how NEAR was designed. It's not just a technological contribution; it's a paradigm shift.
Now, Polosukhin continues working to make blockchain even more scalable and user-friendly. And judging by how the industry is developing, his influence is only growing. When you see how projects adapt his approaches, you realize: this is a person who doesn't just follow trends, but creates them.
