Polkadot 対 Ethereum – 違いは何ですか？

Polkadot (DOT) と Ethereum (ETH) の違いを理解することは、全体的な取引スキルを向上させる賢い方法です。暗号通貨を長期間取引している人なら誰でも、Polkadot と Ethereum が市場で大きな支持を得ている二つのプロジェクトであることを知っています。これらのブロックチェーンは、DeFi（分散型金融）Dapp をフルサポートする安全なスマートコントラクトのプログラマビリティを提供します。

These networks serve similar roles, but they operate in a very different manner. Ethereum was the first blockchain to successfully introduce smart contracts to the market. This network remains a pioneering force in the industry. However, it lacks scalability and functionality compared to today’s latest networks. Here’s some insight into the Polkadot (DOT) vs Ethereum (ETH) debate.

共通の歴史

The first thing to understand is that Ethereum and Polkadot share a history. If Ethereum never succeeded, it is very likely that Polkadot would have never been an idea. This assumption can be made because Polkadot was founded by Ethereum co-developer, Gavin Wood.

Wood, who operated as the CTO and core developer on the protocol is one of the most recognizable and respected developers in the market. He invented the Solidity programming language which remains a core component of Ethereum. In early 2016, Wood decided to leave Ethereum to create a blockchain suited to the direction he saw the market heading. Polkadot was born out of this desire.

Polkadot とは？

Polkadot is a flexible decentralized network designed to connect blockchains securely. Developers can connect networks using Polkadot as a secure connectivity layer. The network enables developers to decide how much integration to leverage. This technical structure makes it easier to build Dapps. It introduces some new concepts to the crypto market which enables the network to offer lower fees and easier programmability.

Parity Technologies is the official company behind the project. This group originally operated as EthCore. In 2017年10月, the network hosted an ICO (initial coin offering) that secured $245 million. The ICO made headlines as one of the largest to date.

In 2018, Polkadot launched its testnet successfully and secured additional funding from the Web3 Foundation to further the network. Later in the year ChainSafe and Soramitsu received grants to implement the Polkadot Runtime Environment in Go and C++. Today, Polkadot encompasses a large ecosystem with new developers and users joining the network daily.

Ethereum とは？

Ethereum launched in 2013 as an early comer to the market. Vitalik Buterin is Ethereum’s founder and lead developer. He launched the protocol with the goal to streamline Dapp development and drive blockchain adoption. Like Polkadot, Ethereum hosted one of the largest ICOs of its time. The network raised $18 million from 11,000 international investors. This funding helped the network become what it is today.

Ethereum changed the market forever, as it switched the focus of cryptocurrencies from acting as money to supporting Dapps. Decentralized applications are a key component of the blockchain sector. Interestingly, Ethereum is often confused with its utility token ETHER (ETH). Ether is the token that enables smart contracts to run on the Ethereum blockchain.

Ethereum is the world’s largest Dapp ecosystem and the second-largest PoW (Proof-of-Work) in the world. Ethereum has seen considerable growth as the DeFi movement has leveraged its proven security. Today, Ethereum is the largest DeFi network in operation. The protocol remains a top choice for developers. However, there are some technical restrictions the network suffers from.

Polkadot (DOT) が解決するために構築された問題は何ですか？

Polkadot was built to provide an alternative to Ethereum that offered lower fees and more scalability. Polkadot integrates a sharded infrastructure to accomplish this task. Additionally, It enables developers to leverage multiple blockchains securely to build next-gen applications. To achieve this task, the network introduces the concept of parachains and parathreads.

Ethereum (ETH) が解決するために構築された問題は何ですか？

Ethereum was built to simplify Dapp development. It was the first protocol to introduce smart contract scripting functionality to decentralized networks. The developers wanted to make it easy for people to enter the ecosystem. As such, they made Ethereum flexible in terms of programming languages. Ethereum developers may use C++, Java, JavaScript, Python, Ruby, and more.

Polkadot はどのように機能しますか？

Polkadots uses parachains and apartheids to improve interoperability in the blockchain sector. Parachains are sovereign blockchains. They may have their own features, services, consensus, and tokens. These networks may also create their own governance systems. Parachains are best suited for specific use case scenarios.

Parathreads are networks that are designed to service Dapps that only require minimum blockchain integration. These networks operate on a pay-as-you-go model. This approach lowers the overall cost of integrating blockchain networks into most applications. Polkadot also integrates special bridges to communicate data between private and public networks.

Ethereum はどのように機能しますか？

Ethereum is a Proof-of-Work (PoW) network that relies on miners to approve transactions and validate the state of the network. Developers create programs called smart contracts that execute within the EVM (Ethereum Virtual Machine). The cost of executing these programs is called gas. The more complex the smart contract and the higher the gas fees.
Ethereum is in the middle of a significant upgrade. The network will shift to Ethereum V2 in the coming months. This switch will include a change to a Proof-of-Stake (PoS) consensus mechanism. This maneuver will lower the operating costs and validation costs for the network. Currently, Ethereum has record-high gas fees.

スケーラビリティ

Polkadot is a high-performance blockchain that can handle over 1000 transactions per second. In comparison, Ethereum supports 13-30 transactions per second in its current state. It’s also far cheaper to send DOT compared to ETH at the moment.

トークン

Polkadot uses the DOT Token as part of its electronic payments system and decentralized smart contract environment. The token is flexible in that it can be staked to secure passive returns. You can also use it to participate in the Polkadot DAO (decentralized autonomous organization). This feature enables users to put forth proposals and upgrades to the network. The community votes on the changes, with approved measures funded from the community chest.

Ethereum relies on ETH as its main utility token. This successful coin is one of the most widely accepted cryptos in the world. Users can stake and farm ETH to secure ROIs. ETH token holders can put significant updates to a vote between miners. The protocol will also leverage off-chain communications and support methods to get changes introduced.
