ブロックチェーン
Meaning: Blockchain — the distributed ledger technology underpinning cryptocurrency, discussed in Japanese business and government circles as a foundational Web3 technology.
ブロックチェーン is the katakana transcription of 'blockchain.' In Japan it rose to public prominence during the 2017–2018 cryptocurrency boom and has remained a business buzzword ever since. The Japanese government and major corporations (Toyota, Sony, major banks) have publicly explored blockchain applications. In casual conversation it is often invoked as a shorthand for 'the tech behind crypto,' even by people who do not fully understand the mechanism.
Examples
- ブロックチェーンって結局なんなの?って友達に聞かれて説明できなかった。 区块链到底是什么?被朋友问到了但没能解释清楚。Un amigo me preguntó «¿qué es blockchain al fin y al cabo?» y no supe explicarlo.블록체인이 결국 뭔지 친구한테 물어봤는데 설명 못 했어.
- 銀行もブロックチェーン技術の導入を検討してるらしい。 据说银行也在考虑引入区块链技术。Parece que los bancos también están considerando implementar la tecnología blockchain.은행도 블록체인 기술 도입을 검토하고 있다고 해.
- NFTもブロックチェーン使ってるんだよね、確か。 NFT也是用区块链的吧,好像是的。Los NFT también usan blockchain, ¿no? Creo que sí.NFT도 블록체인을 사용하고 있지, 확실히.

✓ Do Say

✗ Don't Say
- 「ブロックチェーン」と「ビットコイン」を同義語として使わない — ブロックチェーンはビットコインを支える技術だが、ビットコイン以外にも使われる (Don't use ブロックチェーン and ビットコイン as synonyms — blockchain is the underlying technology for Bitcoin, but has many other applications)不要把「ブロックチェーン」和「ビットコイン」当作同义词——区块链是支撑比特币的底层技术,但也有很多其他应用No usar ブロックチェーン y ビットコイン como sinónimos: el blockchain es la tecnología subyacente del Bitcoin, pero tiene muchas otras aplicaciones.「ブロックチェーン」(블록체인)과 「ビットコイン」(비트코인)을 동의어로 사용하지 않기 — 블록체인은 비트코인을 지탱하는 기술이지만, 비트코인 이외에도 많은 용도가 있다
Common Mistakes
- Treating ブロックチェーン as a single product or platform — it is a technology category with many implementations
- Over-simplifying it as 'just the crypto thing' in business contexts where the audience expects a more nuanced understanding
