Benefits and Limitations of Blockchain

Benefits

• Transparency: Data on blockchain is public and can be verified by anyone. This enhances trust and transparency in transactions.
• High Security: Data is encrypted and distributed across multiple nodes, minimizing the risk of attacks. Transactions on the blockchain are difficult to alter or delete.
• Cost Efficiency: Blockchain can eliminate intermediaries in transactions, reducing costs and processing time.
• Data Integrity: Transactions are permanently recorded on the blockchain, ensuring the integrity and accuracy of the data.

Limitations

• Transaction Speed: Blockchain can face issues with transaction processing speed, especially in large networks. The time taken to confirm transactions can be prolonged, affecting user experience.
• Energy Consumption: Some blockchains, particularly those using the Proof of Work consensus mechanism, consume significant energy, raising environmental concerns.
• Management Complexity: Maintaining and managing a blockchain network can be complex, requiring specialized knowledge and considerable resources.
• Regulatory Issues: Blockchain is still not clearly regulated in many countries, which can pose legal risks for projects operating in this space.

RESTful API and Blockchain

Benefits of RESTful API in Blockchain

• Flexibility: RESTful API allows different applications to interact with the blockchain without needing to understand its internal structure. This enhances integration capabilities with external services and other applications.
• Faster Development: Thanks to libraries and frameworks that support RESTful APIs, developers can quickly build and deploy blockchain applications without starting from scratch.
• Ease of Maintenance: Applications using RESTful APIs are generally easier to maintain and update. If a feature needs to be changed, developers only need to update the API without impacting the entire system.
• Tangible Interaction: RESTful APIs enable users to interact directly with the blockchain through user interfaces (UIs), providing a better user experience.

Limitations of RESTful API in Blockchain

• Security: Although RESTful APIs can secure data using HTTPS, protecting data within the blockchain remains a challenge. Security vulnerabilities can lead to data breaches.
• Performance: When there are many simultaneous requests, the performance of the API may be affected. Handling a large number of requests can result in latency in data retrieval.

What is Ethereum?

Ethereum is an open-source blockchain platform, developed to support decentralized applications (DApps) and smart contracts. Founded by Vitalik Buterin in 2013 and officially launched in 2015, Ethereum is not only cryptocurrency but also a full ecosystem for blockchain applications.

History of Ethereum development

Ethereum was born with the goal of expanding the capabilities of the blockchain compared to Bitcoin, by providing a platform for the development of decentralized applications and smart contracts. Vitalik Buterin, the founder of Ethereum, published a white paper on Ethereum in late 2013. Then, the project officially launched in July 2015 with the release of its first version, Ethereum Frontier.

In the following years, Ethereum has continuously developed and updated new versions to improve the performance and functionality of the network. Ethereum version 2.0, a significant upgrade, was implemented with the goal of improving the scalability and security of the system.

How does Ethereum work?

Ethereum (ETH) operates through a distributed network of computers, called nodes. Nodes participating in this network need to install Ethereum Client software. Once installed, the nodes deploy the Ethereum Virtual Machine (EVM), a virtual program that specializes in smart contract execution.

When developers build decentralized applications (DApps) on the Ethereum platform, they use the Solidity programming language to write smart contracts. The EVM is responsible for executing these contracts, while processing transactions and other orders. Each transaction requires a fee called Gas, which is paid in Ether (ETH).

After a transaction is made, the Miner Nodes take care of checking and validating the validity of that transaction. Ethereum currently uses a Proof of Work (PoW) mechanism where the Miner Nodes have to solve complex problems to prove that the work is done and announce the results to the entire network. Other miner nodes will check and confirm this result.

When a new block is created through the Ethash algorithm, the network validates the transactions using PoW, and the transaction information is written to the Ethereum blockchain. Once the data is saved to blockchain, it cannot be changed.

Ethereum 2.0 and the future

Ethereum 2.0, also known as Eth2 or Serenity, is an important upgrade aimed at improving the scalability and security of the network.

One of the main changes is the move from a Proof of Work (PoW) consensus mechanism to a Proof of Stake (PoS). This upgrade also includes improvements such as sharding and improvements to the consensus algorithm, which help the network process more transactions and reduce transaction fees.

With Ethereum 2.0, the Ethereum network promises to become a more robust platform for decentralized applications and smart contracts, while supporting many new initiatives in the blockchain ecosystem such as JasmyCoin market.

Advantages and disadvantages of Ethereum

Advantages:

• Smart Contracts : Ethereum provides a powerful platform for smart contract development, helping to automate transactions and agreements without the need for third parties.
