Ouroboros Chronos provides the first high-resilience, cryptographic time source based on blockchain technology

Global time synchronization across any distributed network is essential to ensure its resilience.

From ensuring up-to-date information between all participants, maintaining accurate transaction processing and block creation, time synchronization is especially important in terms of smart contract deployment.

Concurrency and all that: Cardano smart contracts and the EUTXO model

Cardano is a UTXO-based blockchain, which utilizes a different programming paradigm for decentralized applications (DApps) from other account-based blockchains like Ethereum. The specific flavor Cardano uses is the Extended Unspent Transaction Output (EUTXO) model introduced by the Alonzo upgrade. EUTXO offers greater security allowing for smart contract execution cost…

Djed: implementing algorithmic stablecoins for proven price stability

Cryptocurrency volatility is one of the obstacles to its wider adoption. Blockchain technologies provide benefits such as transparency, data immutability, and proven security of financial operations. Yet, it is harder than fiat currencies to predict how the market will behave, or forecast the value of a digital currency. This hinders using cryptocurrencies as accounting and…

Smart contracts – here we come

Smart contracts – here we come

At the start of March, we implemented Mary ‒ a multi-asset protocol upgrade that allows users to create unique tokens for transactions on Cardano. With the introduction of transaction metadata, then token-locking with Allegra in December, and native token creation, we are laying the foundation to establish Cardano as the leading smart contract platform.

Alonzo, our next…
