The current structure of the Internet relies heavily on centralized data centers owned by a few major corporations. This centralization poses a number of risks and limitations, including data privacy concerns and vulnerability to targeted attacks. Internet Computer emerges as an alternative, offering a decentralized solution to the challenges posed by traditional cloud service providers.
Internet Computer aims to establish a secure, efficient, and scalable network that can host a variety of applications, from financial services to social networks. The architecture is built on several core components:
Traditional smart contracts have been instrumental in blockchain technology, but canisters on the Internet Computer take this a step further. Canisters possess the ability to process their own transactions and are not limited to Motoko; they can also be developed using popular programming languages like Rust, C, and C++.
In the Internet Computer ecosystem, transactions are referred to as messages. Replica nodes process these messages into blocks to form the blockchain. The Internet Computer Protocol (ICP) is employed for communication between replicas.
Scalability remains a significant challenge in blockchain networks. Internet Computer addresses this through the use of subnets, which are smaller groups of nodes. Each subnet is responsible for producing and validating its own blockchain, which enables the network to efficiently scale as needed.
The network utilizes a unique consensus algorithm that involves four main steps:
Security is of utmost importance in any blockchain network. Internet Computer employs an innovative technology known as Chain Key Cryptography, allowing for a high level of security. This technology enables each subnet to possess a single public key while the corresponding private key is distributed in shares among all the replicas.
The Network Nervous System (NNS) is responsible for key generation, overseeing governance processes, and managing token distribution within the network. It acts as the central system that administers various functions across Internet Computer.
Internet Computer offers a revolutionary approach to decentralizing the internet. By leveraging advanced technologies such as canisters and Chain Key Cryptography, it aims to create a more secure, efficient, and scalable digital ecosystem.
