Cardanoは何が違うのですか？
Predictable by design
Extended UTXO model
A Cardano transaction spends specific outputs and creates new ones, so its result and its fee can be checked before it is submitted. One transaction can have many inputs and outputs, paying several recipients or settling several trades together. Fees follow a fixed formula set by protocol parameters, not an auction.
縛りのないステーキング
自己管理のまま、いつでも資産を使えるステーキング
Delegating ada to a stake pool never moves it out of your wallet. There is no lock-up period, no minimum amount to delegate, and no slashing: the protocol cannot take your ada as a penalty. Registering your stake key takes a refundable deposit, and you can spend or re-delegate at any time.
チェーン上で行われるガバナンス
オンチェーンガバナンスとトレジャリー
Protocol changes, treasury spending and even the constitution are proposed and decided on-chain. Ada holders take part by delegating their voting power to a representative or by registering as one themselves. Stake pool operators and a constitutional committee provide checks and balances.
研究に裏打ちされた設計
査読と形式手法
Cardanoの中核となるプロトコルは、まず学術研究として設計され、ほかの暗号学者による査読を経てから実装されました。ノードはHaskellで書かれ、台帳は形式手法を用いて構築されているため、コードを仕様と照らし合わせて検証できます。
