What is blockchain technology central database

It is easy for newcomers to mix up cryptocurrencies and blockchain. Although the first blockchain Bitcoin is a cryptocurrency, it does not necessarily mean all blockchains are or will be necessarily used as payment networks. Blockchain technology has unique properties without which we would not be able to guarantee such a high level of transparency, decentralization and immutability. If you do not understand yet some of the concepts do not worry, we will explain them to you step by step. The following concepts, constitute the foundation of blockchain technology and we will go over them without getting too technical on the implementation details:.

Private Blockchain vs Traditional Centralized Database


Biological Procedures Online volume 23 , Article number: 3 Cite this article. Metrics details. Approaches developed based on the blockchain concept can provides a framework for the realization of open science. The traditional centralized way of data collection and curation is a labor-intensive work that is often not updated.

The fundamental contribution of developing blockchain format of microbial databases includes: 1. Scavenging the sparse data from different strain database; 2. Tracing a specific thread of access for the purpose of evaluation or even the forensic; 3. Mapping the microbial species diversity; 4. Enrichment of the taxonomic database with the biotechnological applications of the strains and 5. Data sharing with the transparent way of precedent recognition.

The plausible applications of constructing microbial databases using blockchain technology is proposed in this paper. Nevertheless, the current challenges and constraints in the development of microbial databases using the blockchain module are discussed in this paper. Continuous multicenter teledata deposition of microbial strains can be provided by the development of some platforms based on the blockchain concept.

Tracing a specific thread of access for the purpose of evaluation or even the forensic will be possible in blockchain based database of bacteria. Mapping the microbial species diversity will become possible by using this concurrent data filling from different blocks. Enrichment of the taxonomic database with the biotechnological application of the strains will be globally accelerated by this instant cooperative data deposition in blockchain-based architecture.

Blockchain is a database with the capability of duplicating, sharing, and synchronizing data distributed through different physical places i. Nowadays, there is a tendency to ignite different non-financial fields by using the newly emerging computational tools of blockchain. Recently, blockchain has been gradually used to handle multidimensional tasks in health care, assets, networking, electronic voting, etc.

Nevertheless, factors such as block production rate, transaction speed, and block size, play a decisive role in the overall performance of the blockchain-based solutions [ 2 ]. A blockchain is a data infrastructure that retains and shares all transactions made since its inception. It is mainly a fragmented distributed database that keeps a list of gradually growing data records protected from manipulation and unauthorized access.

In a blockchain, a user can connect to the network, create new blocks, submit new transactions, and confirm them. An encryption hash is assigned to each block i. If there are any changes in the block, the encryption hash changes quickly, causing changes in the data that may be due to illegal activity.

Thus, due to its solid foundations in cryptography, blockchain is gradually being employed to reduce unauthorized transactions in different fields [ 2 ]. The paper starts with the operational prerequisites of blockchain implementation, and the second section mentions the current non-financial fields of blockchain adaptation. The third section reveals the fundamental concepts of applying blockchain technology in the creation and management of microbial databases. The fourth section elaborates on the supposed properties of the future microbial databases that will develop based on the blockchain platform.

Subsequently, some added value of using blockchain in designing the microbial database is proposed. In the last section, some challenges and limitations in implementing the blockchain for the purpose of building microorganism databases are discussed. The consensus layer is one of the essential layers in any blockchain-based system. This layer is created to maintain the reliability of the network, assuming that there are untrusted users.

Consensus algorithms are responsible for achieving an agreement of distributed systems on a certain amount of data. The role of consensus algorithms is to provide reliability in a network that could have unreliable nodes. Reliability is vital in distributed systems and databases. There are several consensus algorithms, and each one has its advantages and weaknesses. In public blockchains, usually, Proof of Work PoW or its extensions are used as consensus algorithms [ 1 ].

PoW refers to the calculation of the hash value of a block with the required number of main zeros by changing a random number. This process is identified as mining, and it is a process with high processing or energy requirements. When a miner finds a valid node, broadcasts it to other nodes for verification. Consensus algorithms necessarily assume that some processes and systems are not available and that some communications will be lost.

Therefore, consensus algorithms must be designed to tolerate error. Blockchain can help different institutions managing databases by increasing the speed of operations, spending less, reducing individual errors, and improving the level of information security Table 1. The key specification of blockchain databases is that there is no central supervisor or centralized data storage mechanism.

Instead, consensus algorithms manage the decentralized network [ 1 ] and no organizational authorities are required. Blockchain technology combines concepts such as peer-to-peer protocols, hashing algorithms, primary encryption, public-key encryption, and consensus algorithms. A blockchain is based on a decentralized network which its main task is protecting stored lists of records against tampering.

The blocks in the blockchain are interconnected, forming a chain of blocks. All nodes are connected to a flat topology without a central reference or the main server. This structure of the peer-to-peer network makes it completely decentralized [ 3 ]. A ledger is kept in the blockchain, where all committed transactions are stored in a list of blocks. The chain develops as the new blocks are joined gradually.

In a peer-to-peer network, a consensus mechanism is used to ensure that this block is valid before it is recorded in the ledger. After registering the block in the ledger, the entire network gets a copy of the updated ledger.

Participants in the blockchain network are allowed to view the digital ledger, which is shared securely through the distributed computer network. All peer-to-peer network nodes access have peer-to-peer data and create an independent network to generate and share data between these nodes.

Afterward, the blockchain will be the only basis of its validation. Finally, knowing that in the court in China, it is possible to use the Chinese blockchain to validate documents in legal disputes [ 4 ], will ensure the security of the blockchain. The blockchain technology applied for the cryptocurrency is now being extended to other non-financial fields of technologies.

This approach is penetrating to other disciplines that can be revolutionary for the usual way of data sharing the world is used to that. Some unified aspects like an open way of data exchange, prevention of monopolies supervision, the secure validation processes of the transaction, etc. Based on a recent survey the majority of the journal publications describing the new application of blockchain technology has been in the field of Internet of Things IoT , energy, healthcare, finance, resource management, government, exchange, rights management, privacy, supply chain, etc.

Blockchain technology is employed mainly for sharing medical data in the last few years, and prototype tools for this purpose and companies to establish this infrastructure has emerged [ 6 ].

For instance, clinical trial data validation of a breast cancer drug was successfully conducted using a blockchain data system to verify the adherence to the protocol from distributed cloud server services [ 7 ].

The main disciplines in science that blockchain tools are developed so far for them is illustrated in Fig. Decentralization can remove the large flows of traffic to one node i.

In blockchains, the entry, retrieval, and exchanges of data are validated and recorded by a timestamp. This property provides the users to trace the former records directly by access to any node of the network. In regular centralized databases, a person or group owns it and can make changes to it or destroy information.

All the transactions in public databases are transparent and tractable. The records of the activities can be made public so that they will be visible to all participants. Blockchain ensures the accuracy of the stored records because the same version of the historical ledger records is replicated and stored in the network nodes.

In addition, each case is approved by consensus. If fake inputs are entered, they will be detected and eliminated based on the consensus algorithm. Scalability is the ability to afford accommodation for the volume of work and provide storage space by increasing the number of strains or objects.

All pure and applied microbiology research area is impacted by the genetic and phenotype stability of the microorganisms being used as in the experiments either as the object of the study or the reference strains. This stability and reproducibility are needed to sustain productivity in biotech and pharmaceutical companies [ 8 ]. This genetic stability as a constant concern of the academia and industry is conserved by the prevention of microorganisms in Culture Collections CC.

Biological Resource Centers BRC are more comprehensive culture collections focused on supplying high-quality resources not limited to reproducible cells into biotechnology research and development.

Reproducibility of the biotechnological exploitation of microbial sources is warranted by the proper long-term preservation of these cells in CCs or BRCs. Using the blockchain approach in the creation or expansion of a microbial database will remove the hurdles associated with the centralized data entry of a vast number of samples. There are some other microbial databases which have been constructed by other organization rather than collections or their consortia.

For insatance, the construction of the comprehensive database of BacDive demanded manual insertion of strain characteristics from papers in the International Journal of Systematic and Evolutionary Microbiology [ 9 ]. Although, such species descriptive papers only provide data of type strains and not all the species and strains. There is still not a prototype of a blockchain-based microbial database available to the public. There are two main plausible ways by which microbial databases can benefit from blockchain technology:.

Microbial databases can leverage blockchain capabilities to achieve integrity, and non-repudiation which are essential for the microbial reference databases.

In this paper, we suggest implementing a public blockchain infrastructure while minimizing the corresponding monetary cost for building a microbial database. We propose a blockchain-based microbial data collection system demonstrated in Fig. The blockchain mode can assist in building a pool of biological data by creating a unique address for labs, institutes, etc.

In this scheme, the microbial data, including images, physiological traits, sequences, chemotaxonomical data, etc. The sequence of 16S RNA or genome must be defined as the mandatory data required for strain data deposition in each block while some other characteristics such as biochemical or morphological data could be assigned as the optional fields which are not essentially required for deposition in a block while remain amenable to completion by the time when additional data will be available for the strains.

The overall features of blockchain for microbial databases developed based on the blockchain technology can be considered as transparancy, auditability, veracity and scalibility. Scalability of the microbial databases is of importance as the predicted species of just bacteria surpass one million species while there are multiple of this value of different strains at the lower taxonomic level of species ie.

Around Therefore, there is still a lot of microbial physiology waiting to be discovered and biobanked [ 10 ]. Below are some supposed features that the blockchain-based databases of microorganisms can possess and the privileges that can be obtained by implementing this technology in the management of the microbial data for CC, BRCs, or research or industry institutes and individuals are summarized in the below subsections.

Modifications in original data inserted by the institute managing the database are prohibited in all current databases of microorganisms.



What is CBDC and how will it work?

Blockchain technology is often used as a synonym of distributed ledger technology DLT although both are not the same. A blockchain uses several technologies, including distributed ledger technology, to enable blockchain applications. Blockchain technology is a form of distributed ledger technology. A blockchain is a distributed and immutable ledger to transfer ownership, record transactions, track assets, and ensure transparency, security, trust and value exchanges in various types of transactions with digital assets. Distributed ledger technology DLT revolves around an encoded and distributed database serving as a ledger whereby records regarding transactions are stored.

This differs from ledgers that are maintained by banks in a central database. The lack of a central database for blockchain technology means.

Although central banks are among the most cautious and prudent institutions in the world, a new white paper published by the World Economic Forum indicates that these institutions, perhaps surprisingly, are among the first to implement blockchain technology. Central bank activities with blockchain and distributed ledger technology DLT are not always well known or communicated. As a result, there is a lot of speculation and misunderstanding.


Blockchain or Database: Which One is More Secure?

what is blockchain technology central database

Blockchain technology uses a distributed database multiple devices not connected to a common processor that organizes data into records blocks that have cryptographic validation, are timestamped, and are linked to previous records so that they can only be changed by those who own the encryption keys to write the files. The system that supported bitcoin was recognized for its applicability for other purposes beyond currency, leading to a greater recognition of blockchain as a potentially transformational technology. The system leverages computing power to solve complex cryptographic problems proof-of-work that add blocks to the chain and validate the included transactions. This provides an updated chain that colloborates with other nodes, becomes the new reference, and prevents duplicate transactions. Several startups have begun to leverage blockchain as a solution for business.

A database running on the World Wide Web is most often using a client-server network architecture.

What is Blockchain

That is, a database which can be directly shared, in a write sense, by a group of non-trusting parties, without requiring a central administrator. This contrasts with traditional SQL or NoSQL databases that are controlled by a single entity, even if some kind of distributed architecture is used within its walls. I recently gave a talk about blockchains from the perspective of information security, in which I concluded that blockchains are more secure than regular databases in some ways, and less secure in others. This is a key point on which there is so much misunderstanding. A smart contract is nothing more than a piece of computer code which runs on every node in a blockchain — a decades-old technology called stored procedures does the same for centralized databases.


Difference between Blockchain and Database

Few people understand what it is, but Wall Street banks, consultants, and celebrities are buzzing about blockchain technology. It's hard to remove blockchain from Bitcoin, so we'll start with Bitcoin as we work to understand this technology's potential. Download our free report to get all the trends. The impact of blockchain tech could be huge. Big corporations — like Walmart and Pfizer — have completed blockchain pilots, with many more partnering on projects ranging from remittance to title transfer. The tech looks set to only grow in importance.

Originally devised for the digital currency, Bitcoin, the tech community is now finding The blockchain database isn't stored in any single location.

10 ways Blockchain could be used in education

WWW-based databases use a client-server network. The user client with permissions linked to an account is able to alter entries stored in a centralized server. Administrators have complete control over the database. In this case, every user stores, calculates and updates entries in the database - all nodes cooperate in order to ensure safety by coming to the same conclusions.


To that end, I hope this blog post can bring some clarity into the complex world of blockchain. Putting aside all the hype surrounding blockchains or distributed ledgers, the most important question to ask when deciding what technology to use for a certain facet of an application, whether we are talking about a database, a programming language or a platform, is: Why this technology and not something else? And I know SAP does not want to deliver poorly designed or poorly optimized products. In that vein, I will try to examine the weaknesses and strengths of distributed ledger technology and come to what can be called a scope of sensible implementations for distributed ledger technology in an enterprise context. NOTE : I will be referring to blockchains as distributed ledgers throughout this post to assist in differentiating from cryptocurrency implementations.

As the prices of digital currencies skyrocketed during , the underlying blockchain caught many public attention and has become one of the hottest search in google.
