in : ledger containing data relevant to the tokenized assets in transaction
on : oracle link between ledger l
- cross-network atomic swaps via embedded smart contract layer in gnosis oracles
- lightweight CLI written in Rust for tokenization, wallet/node management
- multi-language integration via SDK's
- absolutely no vc's or web3's
- 100% feeless transactions
[] transcations on the gravas.network are exlusively feeless and shall remain so for the existence of the network
[] feeless transactions are made possible by a consensus "grava" or tax on the network, achieved by either proof of stake or proof of work.
- ie. a given delegation transaction must :
1) compute a Proof of Work greater than or equal to the sum of GRV delegation
2) have staked a sum of GRV greater than or equal to the sum of the delegation
// compute grava

phase.1: "gnodes Launch"
Contributors encouraged to participate in the network by deploying gnodes
- PoW reward 60 GRV / block
- PoS reward 30 GRV / block
gnodes (nodes):
- gnodes have embedded oracles with node-specific API
- gravas (master) node : gravas ledger
+ requirements: 200 000 GRV
- gnosis (interop) node : x-chain ledger
+ requirements: 25 000 GRV + PoW
+ liquidity tokenization for X-chain smart contract layer
network specifications:
- algorithm implementation
implementation across the PoW algorithm differs from the PoS algorthm.
+ PoW: sybil-resistant DAG ledger build on modified Quark algorthim
+ PoS: oracle-linked multi-ledger hashgraph algorithm with virtual-voting process
- distributed consensus mechanisms
+ deterministic: user-defined representative gnodes must contain the ledger(s) required to process their transactions and will be queried according to their function.
+ passive participation: not all network participants are nodes in the consensus algorithms
+ synchronized: consensus achieved per epoch across all ledgers globally and maintained synchronized via gnosis oracles
schnorr signature implemented at every transaction
majority algorithm (part.)

Seems a good project. Does pow will start from beging ?

Proof of Work will begin after the first block of phase1 (after the gnode deployment phase) |

This is an incredibly preemptive ANN. Is mainnet set for Q2/Q3 2023?

We were wondering when someone was going to ask about the site countdown! The epoch referenced is the phase1 gnode inception. While we would always prefer to be preemptive over corrective, the timing of the announcement has more to do with phase0. News about phase0 PoS launch, wallet release and premine staking mechanism will be coming soon. |

Plehz. We think it is absolutely time for more info. We have been... busy. Project IS mineable, but with some difficulty if you could ascertain from the descriptions above. Big news incoming. Whitepaper soon. |

Discord is broken, website lists no meaningful information, github is empty.
What is going on with this project? I was so intrigued.
