3 Steps For Building A Blockchain App

Published

on

Most of the applications today are centralized. That doesn’t mean that it can’t be decentralized. Using the blockchain technology can help you with this task. Almost every centralized system and function can be decentralized such as banking, insurance, and currency exchange. Blockchain has the ability to eliminate intermediaries and improve security and transparency. This is why for some, building a blockchain app is a great idea, and here are some of the things you need to know in order to do it.

  1. Set a Goal

Before you develop an app, there has to be a certain goal or a problem for you to solve. Write down ideas on how you plan to resolve the problem and how you expect this app to do it for you. You may, however, find that certain problems can’t be solved by the blockchain. Keep in mind that you will need to invest a lot of time and resources so it’s best if you make a plan beforehand.

  1. Find A Suitable Mechanism

As you know, Bitcoin uses a consensus mechanism called proof-of-work where all the members of a network need to authenticate the transaction. There are plenty of alternatives to choose from. You should research all consensus mechanisms out there such as Proof-of-stake, Byzantine fault tolerant, Delegated Proof-of-Stake etc. Depends on your individual case, choose the one that you think suits best.

  1. Find A Platform

Platforms are great if you don’t want to build an app on a separate blockchain. Most of the platforms are open source, so depends on your consensus mechanism you should choose a platform. The most popular platforms are the Ethereum platform, Hyperledger Fabric etc.

Paxful is a rather similar type of exchange such as LocalBitcoins. It works only with bitcoin and uses the same ad method as LocalBitcoins. The difference is that the sellers pay only a 1% fee. However, their customer support is really slow because of the high number of users.

Bit2C Review: A Top-Notch Israeli Crypto Exchange With Affordable Fees

Aside from the viral crypto news that we are posting every day, in this edition of the blockchain archive we are focusing on one crypto exchange that is making news and getting more and more popular lately - Bit2C. In a world full of crypto exchanges, Bit2C is proudly standing as one of the most dominant local exchanges - active in the Israeli market and offering crypto trading in several digital assets against the local fiat currency, ILS. When it comes to the general accessibility, most of the users on the exchange are required to verify their identity as well as connect their account to an Israeli Bank in order to use the platform. The main advantages of the exchange include:
  • Support of fiat (ILS) and local bank transfers
  • No fees on deposits
  • Extended security (keeping the coins in cold storage and the fiat money separately from the company's operating funds)
The only downside, which could soon be improved, is the fact that there are only a few altcoins listed such as Litecoin, Bitcoin Cash and Bitcoin Gold. However, there are more coins expected on the exchange. Also, there is no coin-to-coin trading. Regarding commissions, the fixed commission for Bitcoin is 0.001 BTC, for Bitcoin Cash it is 0.0001 BCH, for Bitcoin Gold it is 0.0001 BTG and for Litecoin it is 0.02 LTC accordingly. All in all, Bit2C gives the Israeli population a great chance to trade crypto. As an exchange that is developed in Hebrew, it is an entry-level domestic service which offers crypto trading in most of the altcoins against Israeli shekels - and one that works with local bank transfers.
