Sumeragi Parameters ​

TODO Explain sumeragi module. Clarify that it consists of transactions and blocks gossiping, which are two separate processes. Explain how periods & gossip sizes might affect network load & speed of sync. Explain the pipeline of transactions and blocks, refer to consensus section and maybe some others.

sumeragi.block_gossip_period ​

  • Type: String or Number, Duration
  • Default: 10 seconds

The time interval between requests to peers for the most recent block.

Example:

toml
[sumeragi]
block_gossip_period = "5s"

WARNING

More frequent gossiping shortens the time to sync, but can overload the network.

sumeragi.max_blocks_per_gossip ​

  • Type: Number
  • Default: 44

The amount of blocks that can be sent in a single synchronization message.

Example:

toml
[sumeragi]
max_blocks_per_gossip = 4

sumeragi.max_transactions_per_gossip ​

  • Type: Number
  • Default: 500500

Max number of transactions in a gossip batch message. Smaller size leads to longer time to synchronise, but useful if you have high packet loss.

Example:

toml
[sumeragi]
max_transactions_per_gossip = 500

sumeragi.transaction_gossip_period ​

  • Type: String or Number, Duration
  • Default: 1 second

Period for pending transaction gossiping between peers.

Example:

toml
[sumeragi]
transaction_gossip_period = "1s"

WARNING

More frequent gossiping shortens the time to sync, but can overload the network.

sumeragi.trusted_peers ​

  • Type: Array of Peer Ids
  • Optional

Optional list of predefined trusted peers.

Each Peer Id consists of:

  • address: Address of the peer.
  • public_key: Public key of the peer.
toml
peer_id = { address = "localhost:1338", public_key = "ed0120FAFCB2B27444221717F6FCBF900D5BE95273B1B0904B08C736B32A19F16AC1F9" }

An array can be defined in two ways. Like this:

toml
[[sumeragi.trusted_peers]]
address = "localhost:1338"
public_key = "ed012067C02E340AADD553BCF7DB28DD1F3BE8BE3D7581A2BAD81580AEE5CC75FEBD45"

[[sumeragi.trusted_peers]]
address = "localhost:1339"
public_key = "ed0120236808A6D4C12C91CA19E54686C2B8F5F3A786278E3824B4571EF234DEC8683B"

[[sumeragi.trusted_peers]]
address = "localhost:1340"
public_key = "ed0120FAFCB2B27444221717F6FCBF900D5BE95273B1B0904B08C736B32A19F16AC1F9"

Or like this:

toml
[sumeragi]
trusted_peers = [
  { address = "localhost:1338", public_key = "ed012067C02E340AADD553BCF7DB28DD1F3BE8BE3D7581A2BAD81580AEE5CC75FEBD45" },
  { address = "localhost:1339", public_key = "ed0120236808A6D4C12C91CA19E54686C2B8F5F3A786278E3824B4571EF234DEC8683B" },
  { address = "localhost:1340", public_key = "ed0120FAFCB2B27444221717F6FCBF900D5BE95273B1B0904B08C736B32A19F16AC1F9" },
]
