![]() ![]() If you have had the chance to take a closer look at the article mentioned above, you will already have the understanding that running a node, and specifically a set of them can be quite a cumbersome process that can drain the absolute life of you. Rather it is at the start of the stack- on L0 and is related to infrastructure above anything else. One of the biggest challenges for BUIDLing on Web3, especially for rookie developers is far from being down in the list. Want to learn more about nodes, and NaaS providers? Check out our detailed article on the topic here: Overcoming infrastructure challenges These can be very handy, especially considering just how difficult running your own node(s) successfully can be. ![]() They are responsible for running distributed node clients behind the scenes for you, so you don’t have to. In this category, Node-as-a-Service (NaaS) providers can also be found. These can be, for example, updating your wallet’s balance, validating the hash of new blocks, and other such operations. The nodes in a blockchain network serve the purpose of communicating messages between devices in order to share resources and achieve a common goal. While most other members of this layer are out of the scope of this guide, nodes are not. These include internet, network adapters, such as WAN, LAN, and Ethernet, nodes, and the various connection protocols like TCP/IP, RPC, WebSocket, and others. Here you will find all technical factors, responsible for having blockchain technology available in the first place. This is the layer that makes everything Web3 possible. ![]() Layer 0: Hardware and infrastructure for Web3 That being said, let’s do a quick recap with the table below, and wait patiently for a more detailed review of the examples in the segments to come: Figure 1: Web3 layers 0 to 3 examples That is why to keep things relatively simple and easy to digest, we will be referring to both sets of layers, so you don’t get lost along the way. These refer to the architecture itself above anything else and what makes things tough for many is that the same Web3 stack can also be commonly seen arranged in a different set of layers– Layer 0 (L0), which makes blockchain a reality, Layer 1 (L1), also known as the foundation layer, Layer 2 (L2), or supporting technology, and Layer 3 (元), where DApps live.Īnd even if we are just in the beginning, these tongue-twister lists of layers can already cause great confusion. Presentation and application, housing all BUIDLing tools and decentralized applications (DApps).Consensus, determining how agreement between nodes is reached.Network, supporting the peer-to-peer (p2p) interaction.Data, which holds the keys, hashes, and transactions.Hardware and infrastructure, where nodes and virtual machines are.In its essence, the Web3 stack is composed of five main layers in the following order from bottom to top: That being said, let’s dig into the details: Defining the Web3 stack Just tag along with us, as we take a closer look into the Web3 stack and do so with accessible language anyone can understand. These are just some of the tough questions you will be left answering on your own, or at best what you will be sifting through search engine results, Stack Exchange and Stack Overflow posts.īut we have good news for you-you can forget about all the endless digging for the resolution of your queries. What is the best tool for Web3 developers?.How can I scale my blockchain operations?.Which blockchain protocol should I go for?.With decentralization being paramount across the landscape, there is a degree of fragmentation that also comes with it.Īnd it is exactly this fragmentation that turns your humble beginnings into an absolute nightmare, tossing you into the deeps with no map to guide you: As a rookie developer making your first steps into BUIDLing on Web3, navigating the space can be quite a tough nut to crack. ![]()
