As such, developing a smart health consulting online system that incorporates blockchain technology could offer many benefits for patients, providers, and other stakeholders in the healthcare ecosystem.
The research article  explores the use of blockchain in healthcare . The article discusses how blockchain technology can be used to create a trusted and secure environment for insurance transactions, but also notes that there are still many technical and practical challenges to be addressed. Another relevant article  provides an overview of how blockchain technology can be used to improve healthcare data sharing, clinical trial management, and supply chain management. It also discusses potential barriers to adoption and how they can be addressed. The research article that discusses the use of blockchain in smart health consulting online systems  The article proposes a blockchain-based solution for sharing medical records between health-care providers and patients in a secure and efficient manner.
The proposed solution consists of a permissioned blockchain network where healthcare providers and patients are the nodes. Each node maintains a copy of the blockchain, which contains a tamper-proof record of all the medical records that have been shared. The records are encrypted to ensure the privacy and confidentiality of the patients’ data.The article also discusses the use of smart contracts, which are self-executing programs that automate the process of sharing medical records. Smart contracts can ensure that medical records are only shared with authorized parties, and that the data is not altered or deleted without proper authorization.
In a research article titled  the authors propose a smart health consulting online system that utilizes blockchain technology to provide secure, confiden-tial, and reliable health consulting services. The proposed system employs a decentralized network of healthcare providers and patients, and the data exchange is mediated by a blockchain-based smart contract.The authors further state that the proposed system has several advantages, including data se-curity and privacy, transparency, and integrity. By utilizing blockchain, the system can ensure that patient data is protected from unauthorized access and manipulation. Moreover, the system allows for transparent and secure access to patient data, which can enhance the quality of healthcare services. The authors propose the use of a consensus mechanism known as Proof of Authority (PoA) to ensure the integrity of the data stored on the blockchain.

By using blockchain technology, the system is able to reduce the risk of errors and fraud, while also improving the speed and efficiency of these processes.
III. PROPOSED SYSTEM
A SMART Health Consulting System which is de-signed helps patients in diagnosing their disease and prescribe related medicines. Patients can take online appointment and can visit doctor for medication.To secure patients data the proposed system using Block chain technology for storage.The Block chain store each data as block/transaction and associate each block with unique hashcode . While storing new records Block chain will verify hashcode of all previous blocks and if hashcode matches then data is stored securely and doesn’t allow to alter the data/block by hacker or hospital internal employees. Due to this verification Block chain data is called as immutable or tamper proof. Thus it provides more authentication for the proposed system. The Fig-1 showcases the architecture of our system.
As we know hash is a process of converting raw data into another format of data(plain text to cipher text) so that we can’t reproduce it again back.We can achieve the hash value by performing mathematical operations.These operations can be done by using specific functions known as Hash Functions.The proposed system is focusing on using SHA-256 Algorithm ,one of the strongest hash function avail-able.The 256-bit key makes AES(Advanced Encryp-tion Standard Algorithm) is an excellent partner-function. It is specified in the standard ’FIPS 180-4’ of the NIST.Hashing is the process of scrambling raw information to the extent that it cannot repro-duce it back to its original form. It takes a piece of information and passes it through a function that performs mathematical operations on the plaintext. This function is called the hash function, and the
output is called the hash value/digest. Among the many advancements seen in network security, en-cryption and hashing have been the core principles of additional security modules. The secure hash algorithm with a digest size of 256 bits, or the SHA 256 algorithm, is one of the most widely used hash algorithms. While there are other variants, SHA 256 has been at the forefront of real-world applications.
Fig-1 shows how the proposed system works and the connection between front-end(webpage) and the back-end (etherium blockchain) and how the storing and retrieval of data from the database is achieved.
