Papyrus Network key facts¶

This section presents key variables of Papyrus Network setup, which dApp developers need to know.

ChainId = 32328
Block interval = 1 second
Native token for resource allocation = PPR
Native token emission at genesis block = 1000000000 PPR
Mining rewards = (1.5 * A) / 47 PPR per mined block, where A equals to the count of Authority Nodes

Block gas limit = 210284448
Unstaking lock period = 3 * 24 hours (3 days)
Gas refill allocation for an address with X PPR stake = X in wei * blockGasLimit * 60 * 60 / totalStake in wei, where blockGasLimit = block gas limit, totalStake = total amount of PPRs staked in the network with X included (implementation notice: for the first stake created for the address gas is allocated immediately, for subsequent stakes gas is allocated once in an hour by gas refill process)
Gas refill interval = 60 * 60 seconds (1 hour)
Maximum gas allocation limit for an address with X PPR stake = 3 * 24 * X in wei * blockGasLimit * 60 * 60 / totalStake in wei, where blockGasLimit = block gas limit, totalStake = total amount of PPRs staked in the network with X included

New Authority Node voting period = 14 days
Authority Node blacklist voting period = 5 days
Minimum votes required for Authority Node candidate approval = 3
Maximum number of Authority Nodes and candidates each Authority Nodes can vote for = 7
