Nonetheless, existing security proofs are property-based, and as such they do not support composition. In this work we put forth a universally composable treatment of the Bitcoin protocol.  ...  We specify the goal that Bitcoin aims to achieve as a ledger functionality in the (G)UC model of Canetti et al. [TCC'07].  ...  As such, the treatment of [16, 30] does not offer composable security guarantees.  ...

In particular, we use a distributed hash table as a building block to set up randomized shards, and then leverage the sharded architecture to validate blocks in an efficient manner.  ...  Our work focuses on the design of a scalable permissionless blockchain in the proof-of-stake setting.  ...  We adopt (a simplified version of) what is commonly known as the Bitcoin Unspent Transaction Output (UTXO) model. An UTXO can be roughly seen as a user's account credited by some stake.  ...

Electronic Coins

Craig Warmke
<span title="2022-06-13">2022</span> <i title="PubPub"> Cryptoeconomic Systems </i> &nbsp;
In the bitcoin whitepaper, Satoshi Nakamoto (2008: 2) defines an electronic coin as a chain of digital signatures. Many have since defined a bitcoin as a chain of digital signatures.  ...  This is important because the Chain Definition obscures Satoshi's solution to a dilemma in the design of electronic cash, as well as the truth about bitcoin's privacy and fungibility.  ...  She then uses a software application to compose a candidate transaction that sends that bitcoin to one of Bob's addresses.  ...

We present a modular treatment of a hardware wallet ecosystem, by realizing the wallet functionality in a hybrid setting defined by a set of protocols.  ...  We identify the properties and security parameters of a Bitcoin wallet and formally define them in the Universal Composition (UC) Framework.  ...  [6] suggested a universally composable treatment of the Bitcoin ledger, defining Bitcoin's goals and proving that their model is securely realized in the UC frame-work.  ...

First, it provides an untampered distributed ledger, which cannot be deceived by any party. Each transaction in the system cannot go unnoticed by the smart contract.  ...  The newly proposed system will provide a transparent database of VAT transactions according to our smart contract design and at each stage of supply chain, tax will be deducted and stored on peer-to-peer  ...  Understanding Security Mechanism of Blockchain as Case Study of Bitcoin: In Blockchain, security of transactions is ensured through public and private cryptographic keys i.e. transactions are protected  ...
