Blockchain Performance: What you’ll find in this article (Part 1)
Introduction
The blockchain is a technology that has the potential to disrupt many industries and change how we do business. Its decentralized, trustless nature makes it ideal for storing public data like cryptocurrency transactions or recorded legal documents. While there are still some issues that need to be solved before blockchains can be used in production environments, these problems are being addressed by new innovations every day. As more developers choose to use existing frameworks like Ethereum over building their own custom solutions from scratch, it’s becoming easier to build applications on top of blockchains without having to understand all of its underlying mechanics at once
Introduction
What is blockchain technology?
Blockchain technology can be described as an open, distributed ledger that records transactions across many computers. It’s kind of like a database where all the data is stored on multiple computers instead of one central server. This decentralization helps to ensure the security and integrity of all information stored on a blockchain network, which makes it ideal for applications where trust between parties is necessary (like payments).
How does it work?
The basic idea behind how this works is pretty simple: each transaction sent across a network gets recorded by everyone participating in that specific network–so everyone sees all activity happening within their own node(s). Each new block added to any given chain adds onto previous blocks’ records of events; thus creating one continuous record from day one until infinity (or until someone decides they want their money back).
Blockchain Technology
Blockchain technology is a distributed ledger. This means that all transactions are recorded on a public and immutable ledger, which is stored across multiple nodes in a network. In this way, all participants can verify the validity of transactions without relying on a central authority or middleman.
In addition to being distributed across many computers in its network (hence “decentralized”), blockchain technology also uses an algorithm called consensus mechanism to ensure that changes made to its data have been approved by everyone participating in its network before they’re added permanently to its ledger or chain of blocks (hence “consensus”).
What is a Blockchain?
A blockchain is a distributed ledger. It’s an ever-growing list of records (blocks) that are linked and secured using cryptography. Each block contains data, transaction details and other information, such as timestamps and digital signatures. Blocks are linked to one another by cryptographic hashes and act as an immutable record of transactions across the network. Blocks can only be added by consensus among participants in the network – no single party has control over what gets added or removed from any given block on its own terms alone!
A brief history of the blockchain. Part 1. The first successful use-case of a blockchain was Bitcoin.
The first successful use-case of a blockchain was Bitcoin, a cryptocurrency that allows users to exchange value without the need for any third party. This is made possible by leveraging cryptography and proof-of-work algorithms.
Bitcoin uses SHA256 hash functions as part of its mining process; this means that the data being hashed is split into smaller chunks before being processed further by other algorithms.
A brief history of the blockchain. Part 2. The real breakthrough for blockchains came when Ethereum started using smart contracts to perform complex operations like automated financial transactions and voting systems.
The real breakthrough for blockchains came when Ethereum started using smart contracts to perform complex operations like automated financial transactions and voting systems. The ability to run code on a blockchain has led to many new applications, including digital assets that can be traded on exchanges, decentralized apps (dApps), crypto collectibles, oracles and more.
Ethereum is an open source public blockchain platform that allows developers to build dApps and deploy smart contracts. It was created by Vitalik Buterin in 2015 with the goal of creating a network where developers could easily create decentralized applications using smart contracts that run on top of it.
Ethereum’s smart contracts are much more powerful than Bitcoin’s because they allow developers to create their own applications on top of them by accessing off-chain data sources, like databases and APIs.

The main value proposition of blockchains comes from their trustless and decentralized nature as well as their ability to provide transparency through making all transactions visible to all participants at all times.

Blockchains can be used for many different applications, but they are particularly useful in cases where there’s a need for transparency, accountability and security.
Blockchains are an important technology but they aren’t perfect yet, there are still some issues that need to be solved before they can be used in production environments
Blockchains are an important technology but they aren’t perfect yet, there are still some issues that need to be solved before they can be used in production environments.
The problem isn’t the technology itself–it’s how people use it.
Blockchain performance is still not ready for prime time because of a few key factors:
Conclusion
This is just the beginning of our journey into blockchain performance. In Part 2, we’ll look at how Ethereum’s smart contracts can be optimized and what tools are available for measuring their performance.
