Blockchain
Total support for blockchain implementation from consulting to implementation and development is available
Blockchain implementation consulting
In the "Blockchain Introduction Consulting Service" we provide not only general consulting services, but also "blockchain study sessions" where you can learn the basics and merits of blockchain, its differences from existing systems, and actual cases of blockchain introduction, as well as blockchain introduction demonstration experiments (PoC).
This will enable customers to introduce appropriate blockchain technology based on a thorough understanding of blockchain fundamentals.
Blockchain and Digitalization
The digitalization (digital transformation) of society is progressing rapidly these days.
In a digitalized society, not only goods and services, but also physical resources such as securities, bonds, and crude oil, as well as personal information such as nationality and background coming under "value and trust" will be digitized.
The blockchain is a new platform on which to place such digitized value and trust.
Blockchain is the generic name for the distributed ledger system that emerged from the "bitcoin" idea. Blockchain is sometimes perceived as Bitcoin, but this perception is not accurate.
Bitcoin has shown the world that digital value of virtual currency (crypto-assets, or cryptocurrencies) can be realized by blockchain, but this is just one of the use cases of blockchain. We expect blockchain to be applied in a variety of fields beyond virtual currency.
Let us consider how digital values and trust are handled in today's society. For example, the current situation is that they are "centrally controlled" by a system in which certain organizations, such as the state or large corporations, exert dominant power over individuals and society as a whole.
Blockchain, on the other hand, is a decentralized system that does not necessarily assume management by a specific organization. Blockchain may release all members, including not only individuals but also organizations, from the control of specific members, and may link them in a free form, making it possible to build new relationships between members.
Blockchain Features
Introduction to Major Blockchain Platforms
| Product Name | Classification | Comparison of main functions | Features | |
|---|---|---|---|---|
| Virtual Currency | Smart Contract | |||
| Bitcon Core | Permissionless type | Yes (BTC) | None (simple scripting functions only) | The original blockchain and official implementation of Bitcoin. It is the world's largest market for virtual currencies. |
| Ethereum | Permissionless type | Yes (ETH) | Yes | In addition to virtual currency, it has the ability to execute smart contracts. It is the world's largest public smart contract execution environment. |
| Hyperledger Fabric | Permission type | None | Yes | It is developed by the Hyperledger project. It has functions such as limiting the scope of ledger sharing (channels). |
| Quorum | Permission type | None | Yes | It is developed by JP Morgan. Conforms to specifications established by the Enterprise Ethereum Alliance based on Ethereum. |
| Corda | Permission type | None | Yes | It is developed by R3. The ledger is not shared among all participants, but only among the parties involved in the transaction. |
| Sawtooth | Permission type | None | Yes | It is developed by Intel. PoET, which uses Intel hardware, is used for the consensus algorithm, but it can be replaced structurally. |
Glossary
- [Permissionless type] Anyone can participate in the blockchain network without an administrator, public oriented
- [Permission type] Only authorized participants under an administrator can participate in the blockchain network, enterprise-oriented
- [Smart Contracts] Ability to execute arbitrary applications on the blockchain
