What is ethereum?

Ethereum is a decentralized blockchain with smart contract functionality. Ether (Abbreviation: ETH sign is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. It is open-source software.

Ethereum was conceived in 2013 by programmer Vitalik Buterin. Additional founders of Ethereum included Gavin Wood, Charles Hoskinson, Anthony Di Iorio and Joseph Lubin. In 2014, development work began and was crowdfunded, and the network went live on 30 July 2015. Ethereum allows anyone to deploy permanent and immutable decentralized applications onto it, with which users can interact. Decentralized finance (DeFi) applications provide financial instruments which do not directly rely on financial intermediaries like brokerages, exchanges, or banks. This facilitates borrowing against cryptocurrency holdings or lending them out for interest. Ethereum also allows users to create and exchange non-fungible tokens (NFTs), which are tokens that can be tied to unique digital assets, such as images. Additionally, many other cryptocurrencies utilize the ERC-20 token standard on top of the Ethereum blockchain and have utilized the platform for initial coin offerings.

On 15 September 2022, Ethereum transitioned its consensus mechanism from proof-of-work (PoW) to proof-of-stake (PoS) in an upgrade process known as "the Merge". This has cut Ethereum's energy usage by 99%

What is blur market?

The Blur foundation aims to facilitate community-led governance and participation in the DAO and assist contributors with the development and growth of the Blur ecosystem, including, but not limited to: the Blur marketplace, aggregators, and lending protocol (Blend). The BLUR token gives the community control over the DAO and allows the community to actively participate in governance.

BLUR is an ERC-20 token that governs key parameters of the Blur marketplace protocol and lending protocol (Blend). These parameters control the protocols' value accrual and distribution. Voting is proportional to the amount of BLUR tokens a user owns or is delegated. In order to register their voting balance, a user must delegate their token balance to an address (either their own or someone else's). Most of the decisions made by the Blur DAO have on-chain results. To make sure that all decisions are well-informed, as well as properly communicated with the wider community, the governance process in Blur consists of multiple steps.

What is cryptocurrency lending or borrowing?

rypto-financing allows crypto investors to borrow loans in cash or cryptos by offering cryptocurrencies owned by them as collateral. Crypto lending enables the lender to remain the owner of the crypto asset. However, the crypto offered as collateral cannot be used for trading or transacting during lending tenure.

Crypto investors who plan to HODL (crypto term for-Hold On for Dear Life) their crypto assets and have no plan to sell soon can lend the crypto assets and earn interest for that period. The interest earned is also called ‘crypto dividends’. It’s a simple way crypto investors can use to generate passive income by lending their crypto assets.

A crypto loan is a collateralised loan that one can get from a crypto exchange or some crypto-lending platform. The crypto loan functions similarly to a mortgage or a car loan, where you use car or house property as collateral, whereas in this case, you use your cryptocurrency to secure your loan funds.

What is blend?

1/ Introducing Blend: the Peer-to-Peer Perpetual Lending Protocol for NFTs.

Built in collaboration with @danrobinson and @transmissions11 at @paradigm , Blend enables 10x higher yield opportunities than current DeFi protocols and unlocks greater liquidity for NFTs.
Blend, short for Blur Lending, unlocks liquidity for NFTs.

Token markets exploded with the introduction of stronger financial primitives. Now, NFT-native primitives will jump start the next stage of growth for the NFT market.
Blur was built on the principle that tokens are eating the market of fungible assets and NFTs are eating the trillion-dollar market of non-fungible assets.

Methodology

First found contract address of blend it was 0x29469395eAf6f95920E59F858042f0e28D98a20B so we tracked all transaction that origin to this contract from event log table. after that we had to find borrow and lending transactions so we find them as the transfer transaction that goes through blend contact to other and take them as borrow transaction and reverse we take the transfer that goes from blend to other transaction as lending transactions and at last transfers that have id as collaterals.
