Sidechain ユースケース

Posted at

Sidechainの適用先について。

機密取引(Confidential Transaction)

Bitcoinの取引は全て第三者に公開されており、秘密にできない。その課題を克服するためにSidechainを用いる。送信者と受信者にしか知られない取引を実現する。

署名の分離(Segregated Witness)

Bitcoinのスケーリング問題を解決するために、署名を分離する。それによってブロックに空きを作る。

Schnorr Signatureの導入

ECDSAに変わる形で、Schnorr Signatureを認証方法として導入する。
メリットは以下

  • Efficient threshold signatures for n-of-n.
  • Smaller signatures (64 bytes instead of 71-72) with none of the problems that DER encodings have caused for Bitcoin.
  • Provably no inherent signature malleability, while ECDSA has a known malleability, and lacks a proof that no other forms exist. Note that Witness Segregation already makes signature malleability not result in transaction malleability, however.
  • Slightly faster to sign/verify than ECDSA.
