Wondering what to plan for when undertaking blockchain software development?

This is a good question that we will cover in this article. Good blockchain software development saves time and money and also helps ensure your project is as good as it can be.

Blockchain Development: What Do You Plan for?

plan software development

A blockchain software development project needs elaborate planning around several aspects, as follows:

Aspect #1: Decide if you really need blockchain

Not every new technology might deliver business value for you. Will blockchain prove beneficial to you? To know this, ask yourself the following questions:

  • Are you implementing a business model that involves peer-to-peer transactions without middlemen?
    • If you are, then a public decentralized blockchain is useful.
    • Otherwise, such a blockchain doesn’t serve you.
  • Is your proposed business model such that stakeholders can‘t trust each other?
    • Then, they need a transaction processing system where no one needs to explicitly trust each other. The system would decentralize the transaction validation.
    • Public blockchain networks like Bitcoin and Ethereum provide this with their “Proof of Work” (POW) consensus algorithm. However, POW is intensely energy-hungry and expensive. Read about it in “Proof of Work vs Proof of Stake comparison”.
    • If your proposed business has trusted participants, then you should not implement such a blockchain.
  • Do you need a distributed database that a public blockchain offers?
    • Public blockchains replicate the database on every node. This reduces the economic incentives for hackers. If they take out one server, thousands of other servers continue to keep the blockchain network up!
    • If your business doesn‘t need such distributed blockchain databases with so much redundancy, then you should think of using traditional databases like Oracle, SQL Server, etc. Traditional databases have impressive track records over the decades, and they are highly performant.

Read more about these pertinent questions in “Do I really need blockchain? 4 important factors to consider”.

Aspect #2: Decide if you need a crypto token

Assuming you brainstormed with your team and decided that you need a blockchain, it‘s time to decide whether you need a crypto token. Ask yourself the following questions:

  • Are you selling a product/service that must have a crypto token? Are there providers selling a similar product/service without a crypto token? If there are, how are they selling? If there is an existing business model for your proposed product/service, and if it’s working reasonably, then you may not need crypto tokens.
  • Should your customers definitely need to buy crypto tokens to access your blockchain platform? Then, you should plan for a utility token. This kind of token provides access to a platform, and that‘s their primary use case.
  • Are you planning to introduce a crypto token with a promise of future profits for your customers? Well, you are selling a securities investment contract, and that‘s quite different from a blockchain-based product/service. You need to follow securities regulations, and delink your blockchain project from the securities you are issuing!

Read more about this in “Utility tokens vs. security tokens comparison guide”.

Aspect #3: Choose between public vs private blockchain

Now you need to plan what kind of blockchain should you use, i.e., public vs private. Consider the following:

  • Can you afford a fully open network where anonymous or pseudonymous participants can join? If you can, then a public blockchain like Ethereum is fine for you. On the other hand, if you need to restrict your platform to only trusted parties, then you should go with a permissioned blockchain. These are also called “Enterprise blockchains”.
  • Will you process sensitive data? If you do, then you need a private blockchain where you can implement access control and guard your confidential data. If your data could be open for public viewing, then a public blockchain is fine.
  • Public blockchains like Bitcoin and Ethereum don‘t scale well. Every node has the entire information of the blockchain. Every node participates in the transaction validation process. The network can only be as fast as the slowest node. If scalability and transaction throughput are crucial to you, think of using a private blockchain.

Read more about these in “Public vs private (permissioned) blockchain comparison”.

Aspect #4: Scope your blockchain development project

Focus on the project scope. What are you developing?

If you are setting up a decentralized business, then you are planning to develop a “Decentralized App” (DApp). A DApp is a web app with the following characteristics:

  • The front-end can be in any language, however, the back-end should run smart contracts.
  • A DApp must run on a decentralized blockchain.
  • It should be open-source.
  • A DApp must use a cryptographic token, created using modern cryptographic algorithms.
  • No one user should control the majority of these tokens.
  • Any change to the DApp should follow the consensus of its users.
  • A DApp should store data on a decentralized blockchain following cryptographic standards.

Read more about DApps in “How to convert web app Into a Dapp”. You will use a public blockchain for this.

Now, you need to develop smart contracts for DApps. Smart contracts are pieces of code with certain distinct characteristics, as follows:

  • Smart contracts are open-source.
  • They contain “IF-THEN-ELSE” code and transfer cryptographic assets upon fulfillment of predefined conditions.
  • Smart contracts are stored on a blockchain. They are transparent and no one can tamper with them after deployment.
  • They execute autonomously, and the execution is irreversible.

I have earlier explained smart contracts in “How to deploy a smart contract on Ethereum?”.

If you are planning to build your own blockchain project in an enterprise context, then you aren‘t developing a DApp. You can use smart contracts even in that case. However, you could be developing on an enterprise blockchain like Hyperledger Fabric (Fabric). In Fabric parlance, smart contracts are called “chaincodes”.

Aspect #5: Select a DApp blockchain platform

If you are developing a DApp, you need to choose a blockchain platform for it. You have several choices, e.g.:


Ethereum is the most established DApp and smart contract development platform. Let‘s see the following quick facts about it:

  • Ethereum offers a suite of blockchain protocols for DApp development. “Ethereum Virtual Machine” (EVM) is the central component here. It executes the code of DApps and smart contracts.
  • Smart contracts on the Ethereum blockchain are mostly written in Solidity, i.e., a proprietary language. A software developer can also use Vyper for this.
  • Ethereum is highly popular. Over 84% of “Initial Coin Offerings” (ICOs) in 2017-2018 used this platform, as this report
  • Ethereum offers fully decentralized security with the help of modern data encryption and the POW algorithm. This also reduces its‘ scalability and transaction throughput.
  • It plans to transition to the “Proof of Stake” (PoS) algorithm later, which should improve scalability.
  • Ethereum has a well-developed set of crypto token standards. This helps blockchain software developers to build their tokens. The most common standard is ERC20. You can read about important ERC standards in “5+ ERC standards every Ethereum developer should know about”.
  • As of now, developers can use sidechains to achieve scalability. They can use more efficient consensus algorithms for their DApps on their own sidechains. Loom Network, a blockchain start-up offers “Software Development Kits” (SDKs) for creating DApps on “DAppChains”, i.e., application-specific sidechains. Read more about it in “How to Scale an Ethereum Dapp”.

Read about setting up a smart contract and DApp development on Ethereum in “Blockchain software development using the Ethereum network”.


NEO is a smart contract platform developed by a team from China, and it‘s quite like Ethereum. The distinct characteristics of NEO are as follows:

  • They focus on compliance and claim that they support a GDPR-compliant digital identity solution.
  • They use a “Delegated Byzantine Fault Tolerance” (dBFT) consensus algorithm. This involves a team of delegates with clear identities. A 66% consensus among these delegates is sufficient for transaction validation. This improves scalability and transaction throughput.
  • NEO allows smart contract development using popular languages like C#, Java, and Python that developers already use for web development.

Read more about NEO in “ETH vs. EOS, NEO, ADA”.


EOS is another smart contract platform that‘s similar to Ethereum. The differences are as follows:

  • Smart contract development on EOS is possible with C++.
  • EOS offers better scalability and transaction throughput since it uses the “Delegated Proof of Stake” (DPoS) consensus algorithm.
  • Unlike Ethereum, there is no transaction cost in EOS. Users lease their tokens to cover the bandwidth.

Read more about EOS in “EOS vs Ethereum: is EOS a good alternative?”.


Lisk is not a smart contract platform. The following are the relevant characteristics of this platform:

  • This is a platform for building blockchain applications using sidechains. Every application runs on its‘ separate sidechain.
  • Lisk uses a DPoS consensus algorithm, which makes it faster.
  • Developers can use JavaScript to code on Lisk. Many developers know JavaScript, therefore, this is a key advantage.
  • Lisk offers SDKs to help developers further.
  • Lisk allows the integration of smart contract platforms with apps running on its’ side chains.

Read more about Lisk in “Comparison of smart contract platforms”.

Aspect #6: Developing in an enterprise context? Select an enterprise blockchain platform

If you are planning for an enterprise blockchain project, you will use an enterprise blockchain platform. I will describe the key options you have, which are as follows:

Hyperledger Fabric (Fabric)

Fabric is one of the most mature enterprise blockchain platforms. Note the following relevant points about Fabric, including its advantages:

  • It‘s a project developed by the Hyperledger Consortium, an industry group with the objective of promoting enterprise blockchains, open-source blockchain development tools, and frameworks.
  • It‘s a permissioned blockchain framework. Businesses can implement it for their specific use cases, including smart contract use cases.
  • IBM and several technology giants back it. Big businesses like Maersk are already exploring it.
  • Developers can code “chaincodes”, i.e., smart contracts on Fabric using Java, “Golang”, and Node.js, which many developers already know. Read more about it in “Pros and cons of Hyperledger Fabric for blockchain networks”.
  • Fabric uses consensus algorithms that mirror the transaction processing and approval workflows in enterprises.
  • Hyperledger Fabric is a scalable and performant blockchain.
  • It has a modular architecture. A blockchain developer can benefit from pluggable components like consensus algorithms, and develop apps quickly.
  • Fabric has a “Membership Service Provider”, making it easy to implement a permissioned blockchain.
  • This framework uses data partitioning in the form of “Channels” for transactions involving confidential data.
  • Fabric has a “Hardware Security Model” (HSM), additional hardware-based security to protect digital signatures.
  • Starting in late 2018, Fabric is also enabling developers to code Ethereum smart contracts on this platform. Read about it in “Using Hyperledger Fabric to Set up Ethereum smart contracts”.

R3 Corda

R3 Corda, also called “Corda” is another well-known enterprise blockchain platform. Salient points about Corda are as follows:

  • Corda is from R3.
  • This permissioned blockchain has different access levels for different categories of nodes. Organizations using Corda can set up these nodes according to the different organizational roles they have.
  • Corda is specifically designed for the financial services industry. This sets it apart from Fabric, which is industry-agnostic.
  • This platform uses smart contracts. Smart contracts in Corda have specific legal expressions, which makes them suitable for the heavily-regulated financial service industry.
  • The consensus mechanism in Corda ascertains both transaction validity and uniqueness, as follows:
    • Smart contracts ensure validity.
    • The protocol program checks whether any other transactions use any of the input states of the transaction under validation. If no other transaction has used any of these input states, then the transaction in question is unique.
