Red Belly Blockchain

Red Belly Blockchain (RBBC) is an unforkable blockchain able to commit more than 400K transactions per second with a latency of few seconds. The performance was obtained with 300-byte UTXO transactions on up to 100 Amazon EC2 instances. As opposed to mainstream public blockchains, it is not subject to double spending - when an individual successfully spends their money more than once - because its chain of blocks never forks. As opposed to consortium blockchains, it can treat hundreds of thousands of transactions per second coming from a potentially unbounded number of clients. It offers a performance that scales horizontally, which ensures the security of transactions.

Synchrobench is a benchmark suite to compare synchronization techniques, like STM, HTM, locks, read-copy-update, copy-on-write in Java and C/C++. The current version includes six kinds of data structure implementations: binary search trees, queues, linked list, skip list and hash table, arrays. It was ported to x86 (32 and 64 bits), SPARC and Tilera.

Elastic Transactions

ε-STM is the first software transactional memory supporting elastic transactions. Elastic transactions are a variant of the transactional model. Upon conflict detection, an elastic transaction might drop what it did so far within a separate transaction that immediately commits, and initiate a new transaction which might itself be elastic.
