About this subject

Ethereum is a decentralized platform that enables the creation of smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin and other developers, Ether (ETH) is its native cryptocurrency, currently the second-largest by market capitalization in the sector. Unlike Bitcoin, which focuses primarily on financial transactions, Ethereum offers a programmable blockchain, enabling innovations such as decentralized finance (DeFi), non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs).

Ethereum's transition to Proof-of-Stake (PoS) consensus, completed in September 2022 with "The Merge" upgrade, reduced its energy consumption by approximately 99.95%. This historic shift made the network more scalable and sustainable, paving the way for future improvements like sharding. The Ethereum logo, a stylized octahedron, symbolizes the cryptographic structure and multidimensional nature of the platform.

In Brazil, Ethereum is widely used by enthusiasts and investors. The exchange Mercado Bitcoin, one of the largest in Latin America, has offered ETH trading since 2016. Additionally, Brazilian projects such as the real estate token platform ReitBZ and the decentralized social network Steemit (with a strong presence in the country) utilize the Ethereum blockchain. Interest in NFTs has also grown in Brazil, with artists like the collective Vhils and musician Alok launching works on the network.

Globally, Ethereum processes over 1 million transactions daily and hosts thousands of dApps. Its developer community is among the most active, with events like ETHGlobal and the Ethereum Foundation supporting innovation. Despite competition from blockchains like Solana and Polygon, Ethereum maintains leadership in total value locked (TVL) in DeFi, exceeding $20 billion in 2023.

Frequently Asked Questions

What differentiates Ethereum from Bitcoin?

While Bitcoin focuses on financial transactions as a digital currency, Ethereum is a programmable platform that enables smart contracts and decentralized applications, going beyond simple value transfers.

How did 'The Merge' upgrade affect Ethereum?

The Merge changed the consensus from Proof-of-Work to Proof-of-Stake, reducing energy consumption by approximately 99.95% and preparing the network for future scalability improvements like sharding.

Is Ethereum used in Brazil?

Yes, Brazilian exchanges like Mercado Bitcoin and Foxbit trade ETH, and local projects such as ReitBZ and NFT initiatives by Brazilian artists utilize the Ethereum blockchain.
