Intersect Options

Advanced options for instructing Oura from which point in the chain to start reading from.

Feature

When running in daemon mode, Oura provides 4 different strategies for finding the intersection point within the chain sync process.

Tip: Oura will start reading from the current tip of the chain.
Origin: Oura will start reading from the beginning of the chain.
Point: Oura will start reading from a particular point [slot, hash] in the chain.
Breadcrumbs: Oura will start reading from a some points [[slot, hash],[slot, hash]] in the chain.

The default strategy use by Oura is Tip, unless an alternative option is specified via configuration.

You can also define a finalizing point by providing a block hash at which oura will stop reading from the the chain and exit gracefully.

To modify the default behaviour used by the daemon mode, a section named [intersect] needs to be added in the daemon.toml file.

[intersect]
type = <Type>
value = <Value>

type: Defines which strategy to use. Valid values are Origin, Tip, Point, Breadcrumbs. Default value is Tip.
value: Either a point or an array of points to be used as argument for the selected strategy.

The following example show how to configure Oura to use a intersection point.

[intersect]
type = "Point"
value = [
    4493860,
    "ce7f821d2140419fea1a7900cf71b0c0a0e94afbb1f814a6717cff071c3b6afc",
