Blockchain is a distributed, decentralized, and unchangeable ledger that keeps track of all transactions. The inability to edit a transaction once it has been created helps eliminate the need for central servers and outside middlemen. Blockchain improves security and guarantees anonymity by doing away with the need for middlemen in transactions between two parties. It can be applied to a wide range of industries, including real estate, where it can be extremely helpful in avoiding benami transactions. This essay covers the core ideas of blockchain technology and looks at the various ways it can be used in the real estate industry.
Blockchain technology is a decentralized, distributed ledger technology that allows digital information to be recorded, stored and shared securely and transparently. It is achieved through a network of computers that verify and record transactions, using cryptographic algorithms to ensure the integrity and security of the data. Blockchain technology was created in 2008 by Satoshi Nakamoto to record and verify transactions without a central authority. In 2014, Ethereum was introduced, allowing developers to create and deploy decentralized applications on top of the blockchain. Since then, blockchain technology has evolved and found new use cases in industries such as finance, supply chain management, healthcare, and voting systems. There are four types of blockchain: including public, private, hybrid, and consortium blockchains. Public blockchains are open networks that anyone can join and participate in, while private blockchains are closed networks that are only accessible to a select group of people or organizations. Hybrid blockchains combine the features of two or more types of blockchains. Consortium blockchains are a hybrid of public and private blockchains. The choice of which type to use will depend on the specific needs and goals of the project or application. Blockchain technology has a bright future ahead of it, with many of possible uses and room for innovation. Increased adoption, interoperability, scaling, decentralized finance, and environmental sustainability are a few of them. Ultimately, the development of new applications and use cases, growing adoption, and ongoing innovation will likely define the future of blockchain technology.

The introduction of the Internet of Medical Things (IoMT), has drastically transformed the worldwide landscape of healthcare delivery. The proliferation of IoMT devices in healthcare systems brings new issues in guaranteeing the security and privacy of sensitive patient data. We must secure a substantial amount of sensitive data from modification since IoMT is a high-volume, continually developing data domain. Since then, blockchain (BC) technology has been recognised as a distributed ledger that can manage a huge number of intelligent transactions and increase data security at the same time. A comprehensive resource management system may be offered by Blockchain-based security mechanisms with specific customisation and additional levels of authentication and verification. It has functioned brilliantly as a crucial component of the Bitcoin cryptocurrency. This work creates a blockchain-based Internet of Medical Things security management system using homomorphic encryption (HE). Key generation shows how the DOA may enhance cryptographic system security and efficacy. The IoMT-based HE-DOA system provided in this study employs blockchain to secure data exchange and diagnostic models. HE-DOA allows safe data transmission and diagnostic models with BC aid in IoMT. The recommended technique includes data collecting, encryption, and categorization. Blockchains (BCs) securely store data, and IoMT devices are crucial to early data collection. For data encryption, the dingo optimisation algorithm (DOA) may generate the key. Performance experiments and comparison with similar protocols show that the recommended procedure may enhance PSNR, accuracy, and computational time by 19.34%, 95.78%, and 1.887ms, respectively. Comparing HE-DOA to prior studies shows its scalability and durability.
The development of cases or cases in terms of bankruptcy debtor assets, does not rule out the possibility of bitcoin becoming one of the assets or all assets of bankruptcy debtors given the large number of Indonesians who use bitcoin as an investment tool. Therefore, further study is needed regarding the validity of bitcoin as an asset in terms of the Civil Code and Indonesian Positive Law, as well as the validity of bitcoin as an object of general collateral for bankruptcy debtors. This research is a normative legal research (doctrinal research) with a statutory approach method and a conceptual approach using library research data collection techniques including primary and secondary legal materials and analyzed with interpretation techniques. The results of this study indicate that bitcoin is recognized as a commodity subject to VAT and Income Tax (Article 1 number 7 of Bappebti Regulation Number 5 of 2019 and Article 19 of the Minister of Finance Regulation 68 / PMK.03 / 2022). Based on the Civil Code, bitcoin is an intangible asset in the form of digital assets and is movable (Article 503 and Article 504 of the Civil Code) which can be attached to property rights (Article 499 of the Civil Code) and the owner of bitcoin can freely perform legal actions on the bitcoin owned. Bitcoin has fulfilled the elements of a collateral object, namely that it can become property rights, has economic value, can be executed, so that it can be used as an object of general collateral and can be included in the bankruptcy estate.

ABSTRACT. The metaverse is a simulated digital environment that combines augmented reality, virtual reality, block chain, and social media to create user interaction areas that mimic the real world. It uses the block chain to ensure the uniqueness of digital goods, and non-fungible tokens (NFT) are unique and non-duplicable cryptographic tokens on the blockchain. NFT represent collectible digital assets with the same value as physical assets. However, Indonesian law does not provide specific rules for the metaverse and NFT. This research aims to describe the validity of buying and selling NFT on the metaverse, using a statutory approach method, conceptual approach method, normative juridical data collection type, analytical descriptive research specifications, and qualitative data analysis techniques. Ransverse, a virtual land buying and selling platform, does not meet the requirements of the "a lawful cause" clause in Indonesian law, as it does not have certification related to Trading Through Electronic Systems (PSME). Indonesian law mandates the use of rupiah as a means of payment for all transactions, including electronic and physical ones. Ransverse transactions are invalid and illegal, violating the principle of legal certainty. ABSTRAK. Metaverse adalah lingkungan digital simulasi yang menggabungkan augmented reality, virtual reality, blockchain, dan media sosial untuk menciptakan area interaksi pengguna yang meniru dunia nyata. Metaverse menggunakan blockchain untuk memastikan keunikan barang digital, dan non-fungible token (NFT) adalah token kriptografi yang unik dan tidak dapat digandakan pada blockchain. NFT mewakili aset digital yang dapat ditagih dengan nilai yang sama dengan aset fisik. Namun, hukum di Indonesia tidak memberikan aturan khusus untuk metaverse dan NFT. Penelitian ini bertujuan untuk mendeskripsikan keabsahan jual beli NFT pada metaverse, dengan menggunakan metode pendekatan perundang-undangan, metode pendekatan konseptual, tipe pengumpulan data yuridis normatif, spesifikasi penelitian deskriptif analitis, dan teknik analisis data kualitatif. Ransverse, sebuah platform jual beli tanah virtual, tidak memenuhi syarat klausul "suatu sebab yang halal" dalam hukum Indonesia, karena tidak memiliki sertifikasi terkait Perdagangan Melalui Sistem Elektronik (PSME). Hukum Indonesia mengamanatkan penggunaan mata uang rupiah sebagai alat pembayaran untuk semua transaksi, termasuk transaksi elektronik dan fisik. Transaksi yang dilakukan oleh Ransverse tidak sah dan ilegal, melanggar asas kepastian hukum.
