A smart contract is an agreement reached between several persons regarding past, present, and future events. A smart contract, however, lives in a digital format rather than on paper or orally. E-signature software and technologies are being used in digital contracts to identify a person. Much of the time, this calls for human intervention, which involves pre-registration and verification.

Smart Contracts and Blockchain Technology
Blockchain technology is used by smart contracts. Since the blockchain employs sophisticated mathematics to resolve a riddle that is beyond the comprehension of humans, it limits any chance of data manipulation by design. The technology underpinning the Blockchain protects it from human interference. The program code is kept tamper-proof thanks to this technology. Copies of the said digital ledger are stored on computer networks called nodes. They can identify fraud. How do Smart Contracts operate?
On the Ethereum blockchain, smart contracts were first developed. Canadian-Russian Vitalik Buterin initially introduced them in a white paper in 2013. And while Bitcoin can support intelligent contracts, these were not the goals when it was designed. It has not become a utility such as Ethereum due to several factors. Instead, it has stayed a store of value. Once the terms of the contract are satisfied, smart contracts automatically carry out their provisions. It indicates that a third party, such as a bank, broker, or government, is not required. Nevertheless, the legitimacy of these kinds of contracts is frequently protected by governments acting as mediators.
What are Layer-2 solutions?
Following a sharp rise in demand for decentralized applications (dApps), recent months have seen an extraordinary number of scaling solutions developed on the Ethereum blockchain. Layer-2 or “layer 2” solutions are Ethereum scaling solutions built on top of the blockchain. On top of the main Ethereum blockchain, several additional protocols known as Layer 2 make it possible to build smart contracts and decentralized apps (dApps). Various techniques are used to execute smart contracts and transactions mostly outside the Ethereum main chain. However, this is done while still upholding the basic layer-1 chain’s complete network security.
Layer-2 scaling solutions:
These protocols enable programmers to create applications with quicker transaction finality and less expensive gas than they could if they used the layer-1 chain. There are numerous scaling options available for Ethereum that will help with the introduction of Ethereum 2.0.
There are numerous ways to increase transaction speed and confirmation times but doing so frequently has a price. Increased transactions per second (TPS) had traditionally been associated with less security and centralization. Several years ago, this trade-off was discussed, and it influenced Ethereum’s switch from a Proof-of-Work (PoW) consensus method to a Proof-of-Stake algorithm (PoS). However, it might take months, if not years, to finish this. Rather than having a single, massive launch, Ethereum 2.0 is anticipated to be implemented in phases. As a result, many projects are creating what is referred to as “layer 2 solutions” or “layer-2 solutions,” depending on who you ask, to take advantage of the security of the Ethereum blockchain. This phrase describes a smart contract, or group of smart contracts, operating on top of the “layer 1” main Ethereum chain (L1). Solutions at the Layer 2 (L2) level can communicate with the Ethereum blockchain without altering the protocol at the lowest level. As a result, L2 solutions can speed up and reduce the cost of dealing with Ethereum.
What is Sharding?
Through the process of “sharding,” the entire Ethereum network is divided into different “shards” that function like separate blockchains. Through the safe Proof-of-Stake (PoS) consensus method, numerous transactions will be grouped and verified simultaneously for each shard. After being confirmed, the reference to the shard’s state is saved on the primary layer-1 chain. Random nodes validate shards, and each node is given a unique shard to validate. Sharding thus significantly reduces gas prices for end users, storage utilized by miners, and transaction finality times.
The Ethereum Foundation is putting several cutting-edge scaling techniques into practice to make sure Ethereum can maintain the constantly growing user demand. Most Ethereum scaling solutions, often known as “layer 2” or “layer-2” protocols, carry out transaction validation and calculations off-chain.
