• Title: Cuttlefish: Expressive Fast Path Blockchains with FastUnlock
• Authors: Lefteris Kokoris-Kogias, Alberto Sonnino, George Danezis,
• Abstract summary: Cuttlefish addresses limitations of existing consensus-less and consensus-minimized decentralized ledgers. Key insight of Cuttlefish is that consensus is necessary due to contention, rather than multiple owners of an asset as suggested by prior work. Cuttlefish introduces collective objects and multi-owner transactions that can offer most of the functionality of classic blockchains.

• Abstract: Cuttlefish addresses several limitations of existing consensus-less and consensus-minimized decentralized ledgers, including restricted programmability and the risk of deadlocked assets. The key insight of Cuttlefish is that consensus in blockchains is necessary due to contention, rather than multiple owners of an asset as suggested by prior work. Previous proposals proactively use consensus to prevent contention from blocking assets, taking a pessimistic approach. In contrast, Cuttlefish introduces collective objects and multi-owner transactions that can offer most of the functionality of classic blockchains when objects transacted on are not under contention. Additionally, in case of contention, Cuttlefish proposes a novel `Unlock' protocol that significantly reduces the latency of unblocking contented objects. By leveraging these features, Cuttlefish implements consensus-less protocols for a broader range of transactions, including asset swaps and multi-signature transactions, which were previously believed to require consensus.

• Taming the Beast of User-Programmed Transactions on Blockchains: A Declarative Transaction Approach [0.0]
  "Technology of trust" can be used to mediate transactions between non-trusting parties without the need for a central authority. Transactions are native to the blockchain platform or user-defined via user programs called smart contracts. Despite the significant flexibility in transaction programmability that smart contracts offer, they pose several usability, robustness, and performance challenges. This paper proposes an alternative transaction framework that incorporates more primitives into the native set of transaction types.

  We study the interplay between threshold cryptography and a class of blockchains that use Byzantine-fault tolerant (BFT) consensus protocols. Existing approaches for threshold cryptosystems introduce a latency overhead of at least one message delay for running the threshold cryptographic protocol. We propose a mechanism to eliminate this overhead for blockchain-native threshold cryptosystems with tight thresholds.

  We propose UniBlocker, a dense blocker that is pre-trained on a domain-independent, easily-obtainable corpus. By conducting domain-independent pre-training, UniBlocker can be adapted to various downstream blocking scenarios without requiring domain-specific fine-tuning. Our experiments show that the proposed UniBlocker, without any domain-specific learning, significantly outperforms previous self- and unsupervised dense blocking methods.

  We show that total ordering is not strong enough to preserve application semantics under Byzantine fault model. This is due to the fact that malicious miners and clients can collaborate to add their own transactions ahead of correct clients' transactions in order to gain application level and financial advantages. We propose preserving causality preserving total order as a solution.
