Every year, ArcTouch brings together its employees for a three-day hackathon, where groups set out to prototype an idea using new and emerging technologies. This year, we had many blockchain hackathon projects — and we think this speaks to both the growing interest in blockchain by our staff and the potential for companies to benefit from it. My group chose to implement an identity verification system built on the blockchain. Since we planned to leverage smart contracts, we opted for an Ethereum blockchain.
However, for first-round development, using the public blockchain or even the testnet is not always ideal due to long transaction confirmation times. Instead, we looked at a several options for quickly spinning up a private blockchain. By far, the easiest approach is to use a cloud service such as Azure to host a private blockchain network. Azure makes the setup particularly easy by providing an Ethereum Blockchain Consortium template, which features a configurable number of both mining and transaction nodes.
This particular Azure template however, provides a proof-of-work PoW blockchain which, depending on your requirements, may not be the best option for a private blockchain. This consensus setup works well in a private setting because nodes do not need to compete against each other for the privilege of minting blocks, thus eliminating the processing overhead and energy use that comes with PoW block mining and the ethhash algorithm.
Since authorities do not require heavy computing resources, we were able to use a smaller virtual machine size a B1S with the default options. Once the virtual machine was provisioned, we set up our authority node using the following steps:.
Using puppeth, a CLI tool released with geth 1. Pass the address of the authority to the unlock parameter, and for rpcaddr, use the Private IP address of your virtual machine as displayed in the Azure console Networking settings. Be sure to create an Inbound security rule for port in your network security group to allow you to connect to your authority node using the standard web3. The above process takes about 20 minutes, and results in a fully functional, private PoA Ethereum blockchain in the cloud.
This environment is ideal for decentralized application DApp proof-of-concept development, and provides fast and free transactions. You could easily include other virtual machines in the setup to act as dedicated transaction nodes or additional authority nodes for a more representative network. But developing a proof-of-concept is only one step toward developing a full commercial blockchain solution.
DApp security is a notoriously complex topic, and deploying to a public testnet for testing real world scenarios and verifying correct operation is critical.
Integrating your blockchain-based back end with a mobile app front end also requires some solid strategy. Blockchain presents a unique user experience challenge, in that transactions may take many minutes to confirm depending on the gas price you are willing to pay.

How to install and run a Geth node
Ethereum is an open-source blockchain with its own cryptocurrency, ether ETH. While the two names are often used interchangeably, technically Ether ETH is the actual token, and Ethereum is the blockchain technology behind the cryptocurrency. It's not possible to invest directly in Ethereum, but you can buy Ether. Ethereum was founded by programmer Vitalik Buterin in
The Bridge to the Digital Economy
Metrics details. Blockchains are proposed for many application domains apart from financial transactions. While there are generic blockchains that can be molded for specific use cases, they often lack a lightweight and easy-to-customize implementation. In this paper, we introduce the core concepts of blockchain technology and investigate a real-world use case from the energy domain, where customers trade portions of their photovoltaic power plant via a blockchain. This does not only involve blockchain technology, but also requires user interaction. Therefore, a fully custom, private, and permissioned blockchain is implemented from scratch. We evaluate and motivate the need for blockchain technology within this use case, as well as the desired properties of the system. We then describe the implementation and the insights from our implementation in detail, serving as a guide for others and to show potential opportunities and pitfalls when implementing a blockchain from scratch. After being originally proposed as a public, decentralized and trust-less ledger for digital currencies, blockchain technology has gained widespread adoption in many fields [ 1 — 3 ].
Use Bitcoin, Litecoin, Ethereum wallets without downloading the entire Blockchain
Archive nodes running the Ethereum blockchain have now climbed to over four terabytes in size, nearly doubling in a year. This value represents the total amount of data a user would need to download if they intend to run an archive node—a special type of full node that is running in archive mode. These archive nodes store a complete snapshot of the Ethereum blockchain, including all the transaction records that have ever happened, unlike typical full nodes, which simply record a ledger of verified transactions. Archive nodes are not necessarily needed, since full nodes have a copy of all transactions but they are useful for certain tasks, such as finding out how the balance of an Ethereum address at a point in time. The two most popular ways of running Ethereum are Parity and Geth.
How Does Ethereum Work?
Like any vehicle, the Ethereum network needs fuel for its secure operation. We know it as gas. As Ethereum gains popularity, more decentralized finance DeFi transactions are adopting it. Unfortunately, due to the congestion of so many DApps and individual users, this gas fee keeps on increasing. The gas fee is the charge that you pay when performing any transaction on the Ethereum blockchain.
