Choosing the Right Blockchain as a Service Provider

How Do Blockchain and BaaS Work?

In virtually every business process or transaction, enterprises must jump through several layers of bureaucratic tape and meticulous steps to accomplish their goals with compliance and transparency. Blockchain technology simplifies some of this process, removing several middleman technologies and companies and allowing businesses to complete transactions and transfers of data over the blockchain.

Blockchain works by using cryptography to develop a distributed trust network. Any and all authorized participants can make changes to the digital ledger without additional permissions, and those changes are all time stamped and documented. Each change or transaction is documented on an encrypted block that is saved and linked to the previous block in the transactional chain, creating a chain of blocks, or “blockchain,” over time.

Anyone can use blockchain technology for transactions and other business goals that require agentless documentation, and several third-party software companies offer blockchain as a service to help you get started or to launch a private blockchain network. This approach is adapted from other software as a service (SaaS) models, where third-party vendors take existing technology and help companies to optimize it for their needs. Here are just a few of the ways that BaaS providers help businesses with their blockchain goals:

  • Development: Brainstorming the right blockchain protocols and other details for a given business’s needs.
  • Implementation: Assistance with hardware provision, software installation, certificate development and management, and other network configuration requirements.
  • Consultation: Guiding in-house teams as they manage or add to their blockchain strategy.
  • Maintenance: Many features of blockchain implementation need to be updated and closely monitored for security over time, but also need to keep up with an enterprise’s growing blockchain infrastructural needs.
  • Hosting: Several BaaS providers host private blockchain networks for their customers who want to separate and privatize their blockchain needs.

Enterprise Benefits of BaaS

We’ve covered how blockchain as a service works and what some of the top providers offer to their customers, but what tangible benefits does blockchain technology offer to enterprises that choose to invest in it?

Smart Contract Development

B2B transactions like mergers and acquisitions usually take a considerable amount of time and cost a lot of money, especially as both parties have to meet the expectations of outside institutions, such as law firms and banks. Blockchain technology offers ways to simplify these types of transactions and eliminate the middle institutions and individuals from the equation via smart contracts. 

Smart contracts are contracts that are hosted, time stamped, and encrypted on the blockchain ledger, which certifies transactional changes by both parties without needing additional parties to sign on or certify the transaction. Blockchain also makes it possible to exchange assets in blockchain form, often as NFTs, or non fungible tokens, so buying and selling organizations can complete a transaction from any distance and on any timeframe.

Specialty Program Development

Blockchain can also benefit enterprises in customer-facing efforts, such as special program development. With NFTs, several companies are starting to gamify the customer experience and create rewards programs based on NFT ownership.

NFTs make it possible for enterprises to keep track of customer interactions with real-time, updated electronic ledgers that can integrate with other applications and databases. Using NFTs, then, enterprises can see how their customers behave with their brand and use that personalized data to track customer milestones and automate company loyalty programs.

Security Opportunities

Some people have concerns about the security of blockchain since there is no central security hub guaranteed. However, many enterprises rely on blockchain precisely because its transparency and detailed tracking information on the ledger help to prevent unwanted interactions on the chain.

Especially in private blockchain networks, only authenticated users are able to access the chain and make changes to it. Even if a malicious or strange user somehow got into the blockchain, permanent timestamps and transaction recordings make it very difficult for them to alter ledgers that have already been stored.

Business Process Efficiencies

Most significantly to many enterprises, blockchain is a helpful resource for organizing and automating different business processes in areas like e-commerce, identity management, and supply chain management. With regular updates of the transaction ledger and the ability to track the whereabouts of assets at every stage of a product life cycle, many businesses are opting into this technology in partnership with or even in place of enterprise resource planning (ERP) and other business intelligence software.
