Blockchain refers to the distributed database supported by cryptographic principles that allows digital transactions to be recorded and information to be shared through a peer-to-peer network in an immutable and transparent manner.
Blockchain is the name given to the registration base where data is stored on a distributed network without the need for any center or authority.
Blockchain. Just as there are many different kinds of databases there are also many different implementations of blockchain. The use cases described in Section 5 will be used to inform how the Blockchain should be designed. This section describes the high-level architectural implementation choices available, discusses the pros and cons of the choices, and lists implementation requirements for the present document’s use cases. Section 6.1 focuses on participation and consensus implementation and Section 6.2 focuses on transaction implementation.
Blockchain. A blockchain is a decentralized and append- only database, consisting of blocks, which are appended periodically after consensus. Each block contains a number of transactions, which are validated by miners and stored by full nodes. Denote itv as the block interval, i.e the time interval between two contiguous blocks. Note that itv varies in a small proportion, the average of which is close to a preset value defined in the blockchain system, which is ensured by a consensus algorithm. For example, the preset block interval of Bitcoin [17] is 10 min, while Ethereum [18] has a 15 sec interval. This brings the definition of latency. Denote T as the time when a user submits a transaction to a blockchain, and C as the time when the transaction is included in a block, then C T is the confirmation delay for this transaction, or the latency. One can see that by definition, C T can also be roughly expressed as n itv, where n stands for the number of blocks passed by. Each block has a capacity limit because a larger block usually brings additional network latency during consensus, which increases the chance of forks and causes less performant full nodes to gradually loose its ability to keep up with the network due to space and speed requirements. Since block capacity is limited, the latency issue occurs when the blockchain system is overwhelmed by transactions.

Blockchain. The Ethereum blockchain is prone to periodic congestion during which transactions can be delayed or lost. Individuals may also intentionally spam the Ethereum network in an attempt to gain an advantage in purchasing cryptographic tokens. Buyer acknowledges and understands that Ethereum block producers may not include Buyer’s transaction when Buyer wants or Buyer’s transaction may not be included at all.
Blockchain. Chain of blocks: It is a single record of information, agreed and distributed in several nodes of a network.
Blockchain. 3.13.1 Definition BlockChain (BC) is “a distributed ledger that maintains a continually growing list of publicly accessible records cryptographically secured from tampering and revision” (Hou, 2017, p. 1). BC technology can be used to improve the quality of government services (Hou, 2017) by ensuring greater transparency and accessibility of government information (Atzori, 2017), development of information-sharing across different organizations, and assistance in building an individual credit system. BC-based platforms can be used to give citizens or even businesses (Engelenburg et al., 2019) access to reliable government information, which can in turn strengthen the government’s credibility. Moreover, within the BC system, every transaction is recorded, which makes it easy to trace the parties authorizing transactions and understand the scope of the transaction. It also means that data can be more easily and safely transferred between different organizations and promoting the integration of information amongst different organizations. Ølnes (2016) reveals that storing certificates on the blockchain is a cost-effective way of storing and securing vital information. Thus, social benefits such as a more collaborative society could be a result of BC technology usage in government (Swan, 2015). Why is it relevant to Government 3.0? Blockchain can be used as a recordkeeping solution. As long as BC technology uses public keys in association with cryptographic signatures, it provides secure transactions and reliable records. It is particularly useful for the realisation of secure eID service.
