In the Web2 world, centralized servers host the resources that applications need to run. Web3 has brought the development of dAPI, or decentralized API which provide access to the underlying data or functionality of dApps and protocols, distributed among a network of nodes instead of a few centralized servers. Blockchain Distribution Networks (BDN) bypass the middleman found in Content Distribution Networks (CDN), providing increased safety and adaptability.
What is API?
API is the infrastructure interface that allows different pieces of software to communicate with each other. API can be used to both share data, or to provide access to the functionality of another system.
What is dAPI?
dAPI provides access to dAPP’s or protocols, allowing direct communication between users and decentralized applications. Though similar in result to traditional API, a decentralized API services data and builds the system in a decentralized manner, which creates some specific benefit for both users and developers.
Advantages of dAPI
Flexibility: dAPI are more efficient in how they serve API requests. Whereas a traditional CDN relies on Centralized servers, which are prone to single points of failure, dAPI are more adaptable. Think of a spider web, and how its pattern provides stability. An unsuspecting prey lands on it, trying to rip it apart, but because the web is connected via so many points, it remains stable. Since dAPI have a large number of gateways, the network can adapt to serve traffic easier and more effectively, without disrupting the overall reliability of the BDN.
Scalability: As dAPI infrastructure receives increased demand, BDN are more adaptable than their web2 counterparts. Adding a new node to the system can easily help to improve performance. BDN networks incentivize nodes to be run in regions where they are needed most, meaning the network stability isn’t compromised as its scale grows.
Security: BDN provides increased security for both users and the system as a whole. It is much more difficult to hack or compromise dAPI systems since hackers would need to access multiple nodes to gain access to the functionality they want to control. Additionally, user data is more secure since there isn’t a single entity controlling the data, limiting the risk of a data breach, or unfair censorship regulations imposed on network users.
Though dAPI provide key advantages, there are some disadvantages.
First, since the network is decentralized, updating the code to ensure dApp functionality can be a challenge. Second, creating standardization across every node is more complex. BDN are more complex than their CDN predecessors, with new nodes being added and removed continuously as the network adapts. BDN therefore need a type of automated verification to ensure nodes are running up to standard, or removed. If not, dApp functionality can be greatly hampered when node bandwidth and latency isn’t regulated to specific standards.
As blockchain technology grows and is adopted, it is important to ensure access to decentralized data and services. BDN are needed to create interoperability between different chains, providing scalability and reliability for applications wanting to build dApss on Layer 1 platforms like Ethereum. BDN provide many key advantages over CDN, ensuring speed and reliability without compromising cost to users and developers.
MassBit is a decentralized infrastructure project. MassBit, which is based on proof-of-stake, uses a verification protocol to create products that are decentralized, providing faster, cost-effective, scalable and more stable solutions for Web3 apps.
