What is a Layer 1 blockchain?

The meaning of Layer 1 in blockchain technology is the underlying structure of a blockchain network. It is responsible for establishing consensus, processing and validating transactions, maintaining integrity of data and providing security to prevent malicious actors from taking control of the network. Layer 1 also includes smart contract capabilities that enable developers to create applications on top of the blockchain. These applications can be used to facilitate various types of financial transactions, store records securely, and automate processes such as loan approvals or asset management. Layer 1’s development has enabled businesses to build highly secure, immutable systems that are resistant to tampering and fraud. Layer 1 technology provides users with more control over their digital assets while ensuring that all participants in a transaction have full transparency into the entire process. Overall, Layer 1 is an essential component of blockchain technology that helps make applications more secure, efficient, and trustworthy. By creating a secure framework, Layer 1 technology is enabling businesses to unlock the potential of blockchain and usher in an era of financial innovation.

Layer 1 is also responsible for providing a platform for users to interact with each other securely. It does this by utilizing cryptography and digital signatures, which ensure that only authorized parties can access a transaction or system. This technology helps to protect the privacy of users and prevents malicious actors from infiltrating the network. Additionally, Layer 1 allows users to create public-private key pairs, allowing them to securely store their funds while giving them control over who can access it. By leveraging these cryptographic tools, Layer 1 makes sure operations remain secure and immutable even in decentralized networks without a central authority managing them. In conclusion, Layer 1 technology is an essential component of blockchain technology that provides many benefits such as increased security and increased trust.

Simplified Example

Layer 1 in cryptocurrency is like the blueprint of a house. Just like how a blueprint shows the layout and design of a house, Layer 1 shows the layout and design of a cryptocurrency network. It's the fundamental protocol that governs how the network operates, and it's the foundation for all the other layers. It's like the blueprint of a house, it shows the layout of the rooms, the placement of windows and doors, and the overall design of the house. Similarly, Layer 1 shows the layout of the cryptocurrency network, the rules it follows, and the overall design of how the network operates.

History of the Term "Layer 1 Blockchain"

The term "layer 1 blockchain" is thought to have surfaced in the early 2010s during the proliferation of blockchain technology and the inception of diverse blockchain projects. It pertains to the primary or foundational layer within a blockchain network, serving as the fundamental stratum that furnishes the essential infrastructure and capabilities for securing and authenticating transactions.


EOS: A layer 1 blockchain, EOS uses a decentralized, multi-threaded architecture and a delegated proof-of-stake consensus mechanism to provide fast and scalable transactions for decentralized applications.

TRON: Another layer 1 blockchain, TRON uses a Delegated Proof of Stake consensus mechanism to support high-throughput transactions and decentralized applications.

Steem: A layer 1 blockchain that powers the Steemit social media platform, Steem uses a proof-of-stake consensus mechanism to secure its network and reward content creators and curators.

  • Layer 2: A term that refers to technologies that are built on top of existing blockchain networks, allowing them to scale in terms of throughput and cost.

  • Blockchain 1.0: A term used to describe the first generation of blockchain technology, which is most famously represented by the cryptocurrency Bitcoin.
