Once a transaction is confirmed and included in a block, it is considered final and cannot be reversed. The network ensures that no one can spend the same BTC twice by using a UTXO (unspent transaction output) model, where each transaction output can only be spent once. In other words, the network is preventing double spend to ensure the integrity of the blockchain. Layer 1 crypto projects Layer-2 refers to a network or technology that operates on top of an underlying blockchain protocol to improve its scalability and efficiency. This category of scaling solutions entails shifting a portion of a blockchain protocol’s transactional burden to an adjacent system architecture, which then handles the brunt of the network’s processing and only subsequently reports back to the main blockchain to finalize its results. By abstracting the majority of data processing to auxiliary architecture, the base layer blockchain becomes less congested — and ultimately more scalable.

Below is a top-five list of layer-1 blockchains. Mind you, this isn’t a list of the best-performing chains by market cap. Rather, it consists of projects with a combination of value, robustness, and flexibility that makes them unique in the blockchain world. What is Layer 3 in Blockchain? In contrast, projects built on a layer 1 blockchain have no say in governance, network proposals, transaction fees, or other network metrics. This is why layer 1 cryptocurrencies are so popular with investors. They’re generally viewed as long-term projects, as it often takes many years to develop a fully functional ecosystem.

Liquid Network is primarily used by traders, crypto exchanges, trading desks, and crypto asset issuers. Asset issuers can launch stablecoins, security tokens, and other crypto assets using the platform. 2015-2022: The Proof of Work Era Sharding: Sharding is a mechanism adapted from distributed databases that have become one of the most popular Layer-1 scaling solutions. Sharding entails breaking the state of the entire blockchain network into distinct datasets called “shards” — making it easier to manage than to require all nodes to maintain the entire network. These network shards are simultaneously processed in parallel by the network, allowing for sequential work on numerous transactions simultaneously.
