## Introduction
When a new node joins the network or a previously-bootstrapped node has been offline
for a while,
it cannot follow the most recent honest chain solely by receiving only new blocks
because those new blocks cannot be added to the block tree
that does not have their parent block.
These nodes MUST first catch up with the most recent honest chain
by fetching missing blocks from their peers
before they start listening for new blocks.
This document specifies a protocol for nodes to bootstrap with the honest chain
efficiently while mitigating long range attacks.
It also defines how to handle the case which the node falls behind
after the bootstrapping is complete.
This protocol adheres to the key invariant:
We MUST never roll back blocks that are deeper than the latest immutable block
$B_\text{imm}$ in the local chain $c_{loc}$,
as defined in Cryptarchia v1 Protocol Specification.

| Constant | Name | Description | Value |
|----------|------|-------------|-------|
| -------- | ---- | ----------- | ----- |
| $T_\text{offline}$ | Offline Grace Period | A period during which a node can be restarted without switching to the Bootstrap rule. | 20 minutes |
| $T_\text{boot}$ | Prolonged Bootstrap Period | A period during which Bootstrap fork choice rule must be continuously used after Initial Block Download is completed. This gives nodes additional time to compare their synced chain with a broader set of peers. | 24 hours |
| $s_\text{gen}$ | Density Check Slot Window | A number of slots used by density check of Bootstrap rule. This constant is defined in Cryptarchia Fork Choice Rule - Definitions. | $\lfloor\frac{k}{4f}\rfloor$ (=4h30m) |
