The real estate markets currently hold and contribute a fair share of any country’s gross domestic product. In real estate transactions, stamp duties produce income that adds to the government funds. However, the transactions in real estate may be subjected to forgery through fraudulent papers or activities. Many reforms have been proposed but distributed ledger technology offers solution to most of these issues. A traditional proof-of-work consensus causes an overhead of a large number of message exchanges, which takes a much longer time. This leads to an increased number of utilized blocks for storing transactions, and the required computational power is enormous. This article proposes a blockchain-based system for digitizing transactions in real estate that mitigates the possibility of falsifying documents and other fraudulent activities. The article also proposes a consensus algorithm, which reduces overhead transmissions by around 50% for multicasting nodes. The proposed consensus approach has been compared with five prominent approaches: proof-of-work, proof-of-stake, delegated-proof-of-stake, load-balanced, and a trust-based approach. The comparative assessment deduces that the proposed consensus process is faster than the compared approaches. The overhead of message exchange communication decreases by up to 50.30% compared to the traditional proof-of-work approach.

房地产市场目前在任何国家的国内生产总值中都占有相当比例的份额。在房地产交易中，印花税产生的收入增加了政府资金。但是，房地产交易可能会通过欺诈性文件或活动进行伪造。已经提出了许多改革，但分布式账本技术为大多数这些问题提供了解决方案。传统的工作量证明共识会导致大量消息交换的开销，这需要更长的时间。这导致用于存储交易的使用块数量增加，并且所需的计算能力是巨大的。本文提出了一种基于区块链的系统，用于将房地产交易数字化，以减少伪造文件和其他欺诈活动的可能性。文章还提出了一种共识算法，它为多播节点减少了大约 50% 的开销传输。已将提议的共识方法与五种主要方法进行了比较：工作量证明、权益证明、委托权益证明、负载平衡和基于信任的方法。比较评估推断，提议的共识过程比比较方法更快。与传统的工作量证明方法相比，消息交换通信的开销减少了 50.30%。比较评估推断，提议的共识过程比比较方法更快。与传统的工作量证明方法相比，消息交换通信的开销减少了 50.30%。比较评估推断，提议的共识过程比比较方法更快。与传统的工作量证明方法相比，消息交换通信的开销减少了 50.30%。
