CROSSLINK IMPLEMENTATION
DEPLOYMENT VECTOR
Tracking the trajectory of Crosslink development.
From prototype to mainnet activation.
CROSSLINK ROADMAP

PLACEHOLDERS AND PROCESSES
This initial milestone will provide the code structure and minimal functionality with no consensus modifications.
DISCONNECTED BFT
Introduce BFT functionality, although Zcash's existing consensus will be completely unaltered.
POW CONSENSUS
First modification of PoW consensus to respect the assured finality provided by the BFT protocol.
STAKING TRANSACTION SEMANTICS
Introduce new transaction functionality to enable all of the staking operations, such as delegations, PoS roster selection, and rewards issuance.
PRE-PRODUCTIONIZATION, TECH DEBT, FINAL REFACTORING
Milestone 5 revisits the prototyping design choices to plan out the Mainnet production readiness roadmap through 2026.
PRODUCTIONIZATION PHASE
Transition from the Prototype Phase to the Productionization Phase to integrate Crosslink into the Zcash protocol. The engineering roadmap and requirements are established during Milestone 5.
CURRENT MILESTONE
What's being built right now
M4: STAKING TRANSACTION SEMANTICS
Introduce new transaction functionality to enable all of the staking operations, such as delegations, PoS roster selection, and rewards issuance.
DELEGATIONS
Stake holders can delegate to finalizers
POS ROSTER SELECTION
Finalizer roster management
REWARDS ISSUANCE
Staking reward distribution

Transition from the Prototype Phase to the Productionization Phase to integrate Crosslink into the Zcash protocol.
The engineering roadmap and requirements for this phase are established during Milestone 5 (Jan-Feb 2026). Details about audits, testnet, and mainnet activation will be defined then.

shieldedlabs.net/roadmapBEYOND V1
Crosslink V1 is the foundation. Not the finish line.
SHIELDED STAKING V2
EXPLORINGEnhanced privacy for staking operations. Fully shielded delegation and reward claims.
LIQUID STAKING
RESEARCHDerivative tokens representing staked ZEC. Deferred to avoid complexity in V1.
FASTER FINALITY
RESEARCHV1 targets ~1 minute finality. V2+ could push toward sub-10-second.
CROSS-CHAIN BRIDGES
PLANNEDTrust-minimized bridges to Ethereum, Cosmos, etc. Enabled by finality, built post-activation.
Note: These are possibilities, not commitments. V1 must succeed first.
