# Best Blockchain Platforms

  *By [Brandon Summers-Miller](https://research.g2.com/insights/author/brandon-summers-miller)*

   Blockchain platform technology is a decentralized solution to tracking, documenting, and facilitating transactions. These tools create a public ledger relying on globally distributed historical transactions to prevent tampering and fraud. Each interaction is documented in a database that relies on each previous, time-stamped transaction to verify and execute an exchange. Blockchain technology was first utilized for financial transactions, but can be applied to a variety of industries such as e-commerce, supply chain management, and data integration. This self-sustaining database can be used by businesses for documenting exchanges and eliminating fraudulent transactions. These software solutions provide the framework to create applications that rely on any kind of transaction.

To qualify for inclusion in the blockchain category, a product must:

- Create a live, distributed transactional database
- Create user identification labels for active parties
- Verify each transaction on the active ledger for approval
- Freeze any transaction that cannot be verified

### What You Should Know About Blockchain Platforms

### What are Blockchain Platforms?

Blockchain platforms are software solutions that allow businesses to build applications that rely on blockchain technology. Blockchain technology refers to the use of a distributed, immutable ledger that documents transactions, activities, and resource movement across a network. Companies utilize the ledger in various ways, and a blockchain-based ledger system can be applied to any application that relies on any kind of transaction.

Blockchain platforms operate as a development platform with an integrated distributed ledger. This ledger is essentially an encrypted storage space for all kinds of data. The integrated data is then used to help develop consensus mechanisms that will be used to validate and approve transactions. 

The ledger references integrated data and previously completed transactions to prevent fraud and ensure complete historical visibility. Companies can also perform audits of the ledger should suspicion of fraud or misuse arise. While these functions are some of the core features provided by blockchain platforms, they can still be customized by developers to possess additional features, unique user interfaces, and use cases. 

#### **What Types of Blockchain Platforms Exist?**  

Blockchain technology can generally be defined into four segments or protocols. These four main blockchains categories are public blockchains, private blockchains, consortium blockchains, and hybrid blockchains.

**Public blockchain**

Public blockchains are open source, decentralized solutions that anyone can use for transactions, development, or mining. They are, in theory, completely transparent and display each transaction openly for public examination. These ecosystems can not be shut down as there is no centralized control over its availability. Without that centralized authority, there are security concerns, but none about transparency and audibility. 

**Private blockchain**

Private blockchains require permissions to perform transactions, development, or investigation. They’re typically built and utilized by enterprise businesses that do not want confidential information displayed on a public blockchain. This kind of blockchain is easier to secure and monitor but more difficult to investigate or audit.

**Hybrid blockchain**

Hybrid blockchains can utilize any combination of features offered by both public and private blockchains. This provides companies flexibility in terms of governance and security without a complete loss of transparency. For example, a business could limit the blockchain's historical ledger to mask or hide sensitive information without completely closing the transaction history to others using the blockchain.

**Consortium blockchain**

Consortium or federated blockchains limit participants to preselected user groups. Consortium blockchains are mostly beneficial for smaller groups with trusted users. This allows some centralized authority over access to the blockchain, increasing transaction speed, throughput, and privacy. These increased benefits also preserve transparency and visibility for those approved to participate. 

### What are the Common Features of Blockchain Platforms?

The following are some core features within blockchain platforms that can help users build, develop, and deploy blockchain-based solutions:

**Development:** Development features include everything a developer would need to build a fully-functional blockchain application. This includes developer environments, asset libraries, APIs, templates, and more. 

**Governance:** Governance features vary depending on the type of blockchain in use but typically refer to the ability to control user access on private blockchains or peer-to-peer networks and approvals for consortium blockchains.

**Scalability:** Scalability is an important feature to consider when choosing a type of blockchain. For example, consortium solutions with small, trusted networks will not require substantial scalability, but applications utilizing a public blockchain will require scalability to prevent performance, throughput, and availability issues. 

**Workflows:** Workflow features will help businesses build out the transaction process. Pre-made or customizable workflows can provide a basic process for trading, validation, and settlement and allow for additional steps unique to a custom blockchain solution. 

**Peer-to-peer networks:** Access to large peer-to-peer networks is not always a priority but can be if developing a solution that requires consistent transactions. These networks can also be used to identify untrustworthy parties that may threaten the network. 

### What are the Benefits of Blockchain Platforms?

Blockchain platforms can provide various real-world solutions that may be unique to any business or industry. Some of the most common, horizontal solutions include the development and use of smart contracts, cryptocurrencies, and decentralized applications (dApps)

**Smart contracts:** Smart contracts are one of the two most well-established uses of blockchain technologies. Smart contracts, as you might imagine, are contracts with integrated, intelligent features that can ensure certain parameters are met before self-executing a contract. Companies can use blockchain platforms to build smart contracts for any purpose. For example, a real estate developer could program a smart contract to automatically close a deal upon parties meeting requirements for appraisal, inspection, and mortgage approval. 

**Cryptocurrencies:** Cryptocurrencies are the other original use for blockchain technology. These digital assets are used in place of traditional fiat currencies like the US dollar or the euro. Cryptocurrency coins are “mined” by users with access to the blockchain and rewarded after solving complex mathematical problems. 

**Decentralized applications (dApps):** dApps are programs running on a blockchain network. These applications can increase privacy and reduce censorship for users as there is no central authority with access to their information. Various dApps have emerged in the form of exchanges, games, financial tools, and video games, to name a few. 

**Non-fungible tokens (NFTs):** NFTs are digital assets such as art, videos, or music that utilize a blockchain ledger to generate unique, verifiable ownership identifiers for each individual asset. Artists, companies, or content creators can use these to create one-of-a-kind digital assets their fanbase or user community can buy and trade. 

#### Software Related to Blockchain Platforms

Related solutions that can be used together with blockchain platforms include:

[Blockchain as a service](https://www.g2.com/categories/blockchain-as-a-service) **:** Blockchain as a service solutions provide a blockchain platform for companies and individuals to develop applications and solutions that can be deployed on preconfigured, third-party cloud infrastructure. These tools provide less extensibility and centralized control than a pure-play blockchain platform but can save time on development and money on deployment and hosting. 

[Cryptocurrency software](https://www.g2.com/categories/cryptocurrency) **:** Cryptocurrency solutions do rely on blockchain technology at their core but don’t provide the development capabilities of a blockchain platform. There are many cryptocurrency applications, but they all relate to the mining, trading, and storing digital currencies. 

[Smart contracts software](https://www.g2.com/categories/smart-contracts) **:** Like cryptocurrencies, smart contracts rely on blockchain technology and can be developed using a blockchain platform but pertain to a specified use of the highly variable technology. Most of the tools in this category provide prebuilt but customizable smart contracts that run on a specific, existing blockchain network. 

### Challenges with Blockchain Platforms

Blockchain solutions can come with their own set of challenges. 

**Speed and scalability:** There is enormous variance in the speed and scalability of different blockchains. A blockchain’s speed to settlement largely depends on the platform’s ability to handle multiple transactions at once, the number of transactions required to achieve consensus, and the number of users trading at any given time. 

**Security and privacy:** While blockchain technology is often thought of as an inherently private technology concept, this is not always the case. For example, a transaction made on a public blockchain may permanently and publicly archive information related to both parties if programmed to do so. Since private blockchains offer increased privacy at the expense of transparency, there is often a compromise that developers must make in terms of public visibility and user privacy. 

**Efficiency:** For all the examples of potential blockchain-based applications and solutions, there is not as much discussion of whether or not it is necessary to incorporate blockchain functionality. For example, it could add transparency and auditability to an existing transactional process but could slow transactions to half their normal rate. As with any emerging technology, the buzz-worthy technological concept can sound better in theory than it performs in practice.

### How to Buy Blockchain Platforms

#### Requirements Gathering (RFI/RFP) for Blockchain Platforms

Companies considering adopting a blockchain platform for their business should identify their goal and the blockchain protocol capable of meeting their needs. Companies must understand whether they want to utilize a public and open source blockchain ledger with minimal centralized control or governance, a centrally managed blockchain platform, a consortium model, or a hybrid model incorporating aspects of each. 

#### Compare Blockchain Platform Products

**Create a long list**

The long list should include the potential blockchain platforms capable of facilitating the number of transactions required at a speed the company desires. Companies can identify all possible options using resources such as analyst reports, software review sites, and other industry-specific information sources. Look for prior use cases as well. While your solution may be fairly unique in theory, it’s helpful to know that the platform you are considering has been used to successfully develop applications with similar features and functions in the past. 

**Create a short list**

Narrow the long list by identifying must-have integrations and features and bridging support. Evaluating these factors will ensure the solution you choose operates at the scale desired but also extends functionality into other applications and provides users the features or data they require. If the list must be shortened further, a few obvious factors include price, energy usage, and P2P networks. 

**Conduct demos**

When conducting demos of each solution, it is important to ask questions about the platform itself, the skills required to operate it, and the must-have features you require. Your existing staff should be able to learn the tool quickly and utilize their already existing skills without having to learn new coding languages or build out numerous custom integrations. Additionally, consider the platform’s usability and learning curve, and look out for performance issues and other inefficiencies.

#### Selection of Blockchain Platforms

**Choose a selection team**

The selection team should include someone from the development team who will end up using the tools and product specialists who will be pivotal in the execution and development of your solution. Other parties from leadership, finance, and marketing teams can also be considered depending on their involvement in planning, releasing, and promoting future blockchain-based applications. 

**Negotiation**

Development teams and their ability to adopt the application will be key to its success. Individuals leading those teams and other parties in charge of spending should provide a good balance in determining what solution will meet the team and company’s desired requirements while remaining within budget. 

**Final decision**

Once price points are set, it’s important to involve developers and other end users in finalizing the decision. If the platform is well liked, well utilized, and provides satisfactory results, the buyer can take that as a sign that they’ve made the right call. If not, it may be time to consider other options.
