# bitFlyer Blockchain

## Wiki route

This entry sits under [[systems/INDEX|systems index]]. Read it against [[systems/hyperledger-besu-overview|Hyperledger Besu · EVM 兼容企业链(Quorum 进化)]] for peer / contrast context and [[fintech/INDEX|fintech index]] for the broader system / regulatory boundary.

## TL;DR

bitFlyer Blockchain is the enterprise blockchain arm around bitFlyer's proprietary private-chain technology, Miyabi. In FinWiki it should be treated as a **systems / enterprise DLT** node, not as a CEX entity. The page is connected from [[payment-firms/bitflyer|bitFlyer]] because Miyabi is part of the group's B2B blockchain story.

## System profile

- **Core product**: Miyabi, a private blockchain / blockchain-type database for enterprise use.
- **Design claim**: bitFlyer describes Miyabi as finality-oriented and high-throughput, with an official performance claim of 2,000 transactions per second, or 4,000 on advanced hardware.
- **Use case class**: permissioned enterprise workflows, B2B blockchain consulting, and systems where fork risk and settlement finality are more important than public-chain openness.
- **Adjacent network role**: bitFlyer Blockchain has also appeared in web3 research and validator / ecosystem activities such as Oasys-related announcements.

## Strategic read

Miyabi sits on the opposite side of the design spectrum from public permissionless chains. It optimizes for finality, controllability, and enterprise integration rather than open validator economics. This makes it closer to [[systems/canton-overview|Canton]], [[systems/hyperledger-besu-overview|Besu]], and institutional DLT than to CEX market structure.

For [[payment-firms/bitflyer|bitFlyer]], the strategic value is optionality: exchange business on one side, and enterprise chain / consulting infrastructure on the other. The open question is whether Miyabi has enough active adoption to be a durable product line rather than a technical showcase.
