Bitcoin uses the SHA-256 hashing algorithm to encrypt (hash) the data stored in the blocks on the blockchain. Simply put, transaction data stored in a block is encrypted into a 256-bit (64-digit) hexadecimal number. That number contains all the transaction data and information linked to the blocks before that block. A blockchain is a distributed ledger, a shared database of information that is chained together via cryptographic techniques. “Distributed” means that it is stored on many computers rather than on a centralized server, as is typical of data storage.

Understanding Bitcoin

Others are software wallets that use apps on smartphones or other devices to store BTC. Transactions are recorded on the blockchain and visible to everyone. Miners maintain the blockchain by solving complex math problems to validate transactions.

The other nodes will check to make sure it’s a valid block, then add it to their own ledgers. It’s possible for multiple blocks to be created at once, but eventually the network will end up building more blocks on top of one than the other, making that block part of the official chain. As blockchain networks grow in popularity and usage, they face bottlenecks in processing transactions quickly and cost-effectively. This crypto and blockchain articles limitation hampers the widespread adoption of blockchain for mainstream applications, as networks struggle to handle high throughput volumes, leading to congestion and increased transaction fees. This immutability is part of creating transparency across the network and a trustworthy record of all activities on the blockchain. The blockchain simply records every transaction that has ever taken place on its network.

Table 8 summarizes research works aimed at integrating Machine Learning-enabled Blockchain Technologies into healthcare applications. The research spans from 2020 to 2022 and addresses a wide range of topics, including telesurgery, patient data exchange, COVID-19 analytics, and vaccination delivery. AI approaches, illness categorization algorithms, and data integrity by smart contracts on the blockchain are among the main contributions to these studies. However, there are constraints, insufficient empirical validation, and ethical issues about data privacy and algorithmic bias in the published papers. Considering the findings of a study on data (Halevy et al. 2009), if given enough data, even the most basic AI system could surpass most modern technology. For the goal of disease diagnosis and detection, big data may be analyzed using AI algorithms.

How blockchain works: key terms to know

Cryptography techniques, such as public–private key pairs, can also help ensure the privacy and confidentiality of patient data168. The platform also uses smart contracts to automate processes such as data sharing and patient consent. A smart contract can be programmed to automatically share vital sign data with a healthcare provider or family member when certain conditions are met, such as a patient experiencing a sudden change in vital signs169. A framework that is based on cloud and is combined with Blockchain and IoT can provide a powerful platform for data sharing and management in various industries, including healthcare.

Data is essential to AI and ML algorithms, which perform better with reliable, secure, trustworthy, and credible data (Chen et al. 2018). AI in healthcare confronts several obstacles, including ethical use, algorithm biases, data privacy, and trust building. These challenges must be addressed to ensure patient welfare and safety while ensuring data privacy and security.

Blockchain technology uses immutable hash chains and digital signatures as critical components of its security and data integrity mechanisms. A hash chain is a series of hash functions applied to each block of data in the Blockchain. Each block in the chain contains a hash of the previous block, creating a chain of interlinked blocks156. This provides tamper-evident security because any change to a block in the chain will result in a different hash value, which the network will detect. Hash chains ensure the integrity and immutability of the data stored in the Blockchain157. Digital signatures are cryptographic techniques used to authenticate the origin of data.

A comprehensive examination of consensus approaches can be found in the publication114. A brief description of blockchain and IoT is covered in Section “Literature review”. Section “Methods and materials” discusses the technologies that enable secure and advanced IoT-based medical applications.
