What is Postchain?

What is Postchain?

Postchain is a modular framework for implementing custom blockchains. Particularly, it’s geared towards consortium blockchains (also known as permissioned, enterprise, private, federated blockchains, and, sometimes, distributed ledger technology).

What is blockchain system?

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger.

Is BigchainDB open source?

BigchainDB is built on a large, open-source pre-existing database codebase that has been hardened on enterprise usage over many years. New code will be security-audited and open source.

What is blockchain data structure?

The blockchain data structure is a back-linked list of blocks of transactions, which is ordered. It can be stored as a flat file or in a simple database. Each block is identifiable by a hash, generated using the SHA256 cryptographic hash algorithm on the header of the block. Hash functions are collision-free too.

What is open ledger in Blockchain?

Open Ledger is a decentralized financial platform letting its users to convert bitcoin to SmartCoins immediately or by limit order. It is one of the globe’s first decentralized autonomous exchanges based on the blockchain technology.

What are Blockchains used for?

Blockchain technology can be used to create a permanent, public, transparent ledger system for compiling data on sales, tracking digital use and payments to content creators, such as wireless users or musicians.

Is BigchainDB a blockchain?

BigchainDB is a blockchain database offering decentralization, immutability and native assets. BigchainDB allows for the deployment of large-scale applications in a variety of use cases and industries from intellectual property and identity to supply chain, and Internet-of-Things.

Who is Bruce PON?

Bruce Pon is the Founder of BigchainDB and Ocean Protocol, blockchain startups focused on bringing data and AI together since 2013. Previously, Bruce co-founded Avantalion, a consulting firm that helped to build 20 banks around the globe for companies such as Mercedes-Benz, Volkswagen, Mitsubishi & Jaguar LandRover.

What are the three key features of a Hyperledger blockchain for a regulated industry?

Performance, scalability, and levels of trust. Hyperledger Fabric is built on a modular architecture that separates transaction processing into three phases: distributed logic processing and agreement (“chaincode”), transaction ordering, and transaction validation and commitment.

Who maintains Bitcoin ledger?

Nobody owns the Bitcoin network much like no one owns the technology behind email. Bitcoin is controlled by all Bitcoin users around the world. While developers are improving the software, they can’t force a change in the Bitcoin protocol because all users are free to choose what software and version they use.

Where is blockchain ledger stored?

Blockchain is decentralized and hence there is no central place for it to be stored. That’s why it is stored in computers or systems all across the network. These systems or computers are known as nodes. Each of the nodes has one copy of the blockchain or in other words, the transactions that are done on the network.

What database does bigchaindb use?

BigchainDB uses Tendermint to obtain the features of blockchain technology and an open source database called MongoDB for storage purposes. Currently, its stable software release version is BigchainDB 2.0.

What makes bigchaindb different from other blockchain technologies?

Rather than trying to enhance blockchain technology, BigchainDB starts with a big data distributed database and then adds blockchain characteristics – decentralized control, immutability and the transfer of digital assets. No single point of control. No single point of failure.

What is bigchaindb (BCD)?

BigchainDB fills a missing gap in the emerging decentralized stack as a blockchain database that complements existing platforms, processing and file systems. BigchainDB combines the key benefits of distributed DBs and traditional blockchains.

What is the difference between bigchaindb and MongoDB?

In BigchainDB, Byzantine fault tolerance is achieved using Tendermint protocols. Immutable storage: In BigchainDB, if a node gets corrupted or some data is changed, then it is detectable. Because, every node has a local copy of the MongoDB database and transactions are cryptographically signed.
