Bitcoin and Ethereum, hosting the two currently most valuable and popular cryptocurrencies, use two rather different ledger models, known as the UTXO model and the account model, respectively. At the same time, these two public blockchains differ strongly in the expressiveness of the smart ...
Formal investigation of the Extended UTxO model 来自 Semantic Scholar 喜欢 0 阅读量: 2 作者:M Chakravarty,O Melkonian 摘要: Blockchain technology has opened a whole array of interesting new applications (e.g. secure multiparty computation[Andrychowicz et al. 2014], fair protocol design fair[...

账户模型示例图如图3.2示。而比特币中使用UTXO模型来存储状态信息,当需要使用的时候再去溯源得到最终状态。UTXO模型如图3.3示。具体来看以太坊账户可分为两种类型:合约账户和外部账户。它们两个的关系是调用和被调用的关系。外部账户即是以太币的拥有者指的是某个人。合约账户存储的是合约代码,只能由外部账户来调用。当...
Additionally when a Bitcoin wallet does not find enough value on an unspent transaction output (utxo), then it joins together that utxo with another utxo the wallet contains. If the post-mix wallet would function as a normal Bitcoin wallet too, the observer would notice post-mix transactions....

Cardano’s PoS consensus mechanism,called Ouroboros, also reduces energy cost compared to PoW. It also provides provable security guarantees with transactions and seamless execution of smart contracts with Hydra’sExtended-UTxO model. With the current setup of Ethereum (PoW) and Cardano (PoS), Card...
The UTXO model in Bitcoin also allows transactions to be processed in parallel since they refer to independent inputs. Themempoolof Bitcoin are the transactions waiting to be confirmed on the network. Bitcoin only handles roughly 5 – 6 transactions per second (TPS) on-chain, so transactions th...
[15], etc. Ethereum abandons the UTXO transaction model proposed by Bitcoin in favor of the account/balance transaction model and extends the Merkle tree to the Merkle Patricia Trie (MPT) [16]. The Merkle roots originally stored in the block header are changed to three Merkle Patricia tree ...
