Smart contracts are deployed on-chain as source code, making them easier to read and thus safer, and compiled locally on-demand by validators. This flexibility allows existing teams to transition to blockchain development and existing tools and libraries to be reused. Orbs pioneers the paradigm of smart contracts as a library in any language, like Go and JavaScript, instead of dedicated languages like Solidity. instantiate a new AWS machine in the node cluster) allowing for a virtually limitless number of virtual chains to run on the network in parallel. When a new virtual chain is created, Orbs validators dynamically allocate more resources for its execution (eg. The parallel and concurrent operation of different virtual chains results in virtual separation, as smart contracts are likely to interact mostly with smart contracts deployed on the same virtual chain. Applications are also no longer at risk of having their block history reverted due to a network-wide decision such as The DAO fork or prevented from deploying a fix like with the Parity bug. This provides applications with the stability lacking in shared infrastructure solutions and reduces protocol forks as interests are less likely to conflict. Isolation between virtual chains allows each app to make its own protocol governance decisions, such as fixing a vulnerability in a deployed smart contract or customizing a protocol parameter like its consensus block rate. Prevents fee surges resulting from competition for network resources betweenĪpplications and enables a predictable fee model absent from most shared-resources blockchains.

Moreover, the isolation of state for each virtual chain reduces the memory requirements of the network’s virtual machine. The ledgers of virtual chains can also be maintained independently and their compute can be performed in parallel. This provides applications with the security and decentralization of the entire network while maintaining a strong degree of independence.Ĭonsensus on transactions of different virtual chains can be run independently and are run concurrently on separate resources.
#MOVING ORBS IN VIDEOS FULL#
All Orbs validators run all virtual chains in parallel, making the permissionless pool of validators completely shared and staked across the full network. Each virtual chain maintains its own separate chain of blocks, state, and runs its own concurrent instance of consensus. Virtualization provides applications with an isolated environment while utilizing a shared physical infrastructure of nodes. + read more - read lessĮvery application running on Orbs typically runs on its own virtual chain. For example, consider an EVM-based DeFi vault where external Guardians act as oracles over EVM data and allow EVM contracts to make external decisions that are impossible to implement in the EVM alone. The Orbs project is currently focused primarily on DeFi applications, where Orbs’ independent consensus layer can be used to enrich DeFi contracts on EVM-based L1’s such as Ethereum - where most existing liquidity in DeFi resides. Whereas many popular public blockchain solutions like Ethereum are designed primarily for purely decentralized applications (dapps), Orbs expands the offerings of public blockchains by also supporting permissioned applications developed by existing for-profit businesses. The main offerings of the platform include compute under consensus (execution of “smart contracts”) and storage under consensus.Īpplications running on public blockchain are unique in their ability to facilitate trust by providing blockchain-backed guarantees to their users. The Orbs platform is a decentralized serverless cloud allowing developers to build backend services (applications) that are then deployed to be executed by Orbs Guardians.
