This Canton Improvement Proposal (CIP 0107) introduces a 24-hour submission delay for end-user transactions in the Daml layer, making Canton fully compliant with the token standard. The mechanism involves creating a new `ExternalPartyConfigState` contract that stores relevant information from the latest `OpenMiningRound` contract, which is active for 48 hours and copied every 24 hours. This change will impact the token standard implementation of CC, requiring it to rely on `ExternalPartyAmuletRules` and `ExternalPartyConfigState` instead of `AmuletRules` and `OpenMiningRound`.

This Canton Improvement Proposal (CIP 0092) recommends a 10-day transition period for Super Validator (SV) operators to move from fixed on-chain conversion rates to dynamic market-based price feeds after the listing of Canton Coin (CC). During this period, SVs must update their votes for the median price at least once every 24 hours, using reasonable reference prices. This controlled transition aims to maintain stability while allowing SVs to progressively align the on-chain rate with observed market prices.

This Canton Improvement Proposal (CIP-0089) outlines a planned upgrade from Canton 3.3 to Canton 3.4, requiring a Major Upgrade with Downtime for Super Validators and Validators. The upgrade involves a synchronized operational procedure, pausing the synchronizer until completion, and has been tested on DevNet, TestNet, and MainNet for previous Canton releases. The proposed upgrade dates are November 12, 2025, for DevNet, November 26, 2025, for TestNet, and December 10, 2025, for MainNet.

This Canton Improvement Proposal (CIP 0085) adds Talos as a Weight 6.5 Super Validator, with incremental weight earned upon verification of adoption milestones such as Canton Coin trading and custody readiness, pX integration, and measured production usage. The proposal ties rewards to real usage and service quality, with a focus on broadening CC access through Talos integrations and demonstrating private institutional settlement on Canton. The incremental weight is broken down into two key initiatives: establishing Talos platform-wide support for CC and integrating pX for private institutional settlement.

This Canton Improvement Proposal (CIP 0082) establishes a 5% Development Fund, allocated from future CC mint emissions, to sustain long-term investment in the Canton protocol. The fund will be governed by the Foundation and will support core R&D, dev tools, security, audits, and other critical infrastructure. This fund aims to provide durable, programmatic funding for the network's long-term objectives, ensuring all pools contribute to shared public goods.

CIP 0080 adds Republic as a Sovereign Validator (SV) on the Canton Network with a weight of 6. Republic, a leading on-chain investment ecosystem, will integrate Canton's Token Standard into its wallet, enabling secure and customizable token management. This integration is expected to be completed within 180 days of CIP approval, with potential bonuses for early completion.

This Canton Improvement Proposal (CIP 0078) aims to remove Canton Coin fees and adjust holding fees to make Canton Coin more attractive for users and application developers. The proposal involves changes to the Amulet Rules configuration and Splice code to eliminate fees for transferring Canton Coin and simplify the logic for charging holding fees. This change is expected to make Canton Coin and the Global Synchronizer more appealing to users and developers.

Here is a 2-3 sentence summary of the CIP 0076: Hypernative, a blockchain security and monitoring platform, is designated as a Super Validator with a weight of 1, providing real-time threat detection and monitoring services to the Canton network. To earn the full Super Validator reward, Hypernative must deliver a proactive network monitoring solution that detects balance changes, transfers, and other Canton Coin activity, and have at least one entity on the network subscribed to its monitoring alerts. The Super Validator reward will be escrowed and distributed to the Unclaimed Rewards pool, with Hypernative responsible for all costs associated with the operation of the escrowed Super Validator.

Here is a 2-3 sentence summary of CIP 0072: CIP 0072 proposes adding Fireblocks as a Super Validator (SV) on the Canton Network with a weight of 5, allowing it to participate in the network's governance and validation processes. To earn the full SV reward, Fireblocks must deliver wallet support for the Canton Token Standard, accelerate adoption of the network, and meet specific milestones, including driving asset transfers and completing transactions on MainNet. Successful completion of these milestones will result in Fireblocks earning additional SV weight and rewards, including a maximum of +2 SV weight and a share of the Unclaimed Rewards pool.

CIP 0071 adds Ubyx as a Strategic Validator (SV) on the Canton Network with a weight of 5, contingent on achieving milestones and deliverables over an 18-month period. Ubyx commits to building solutions on the Canton Network, enabling regulated transfers of value and integration into its stablecoin clearing platform. This partnership aims to facilitate compliant, privacy-preserving B2B payments at scale and enhance the Canton ecosystem's utility and interoperability.

Here is a 2-3 sentence summary of the CIP 0069: CIP 0069 proposes adding Ledger as a Super Validator (SV) with a weight of 5, allowing it to participate in the Canton network's governance. To earn its full weight, Ledger must deliver three key milestones: supporting the Canton Token Standard on Ledger Live and Ledger Enterprise, achieving an acceleration bonus, and driving Canton adoption among existing Ledger customers. Successful completion of these milestones will result in Ledger earning its full weight and contributing to the network's governance.

This Canton Improvement Proposal (CIP 0068) modifies the network's bootstrapping process to allow SV nodes to start from a pre-configured non-zero round, enabling network resets that maintain historical round progression. The proposal adds an optional `initialRound` argument to the `DsoRules_Bootstrap` choice and introduces a new flag `SPLICE_APP_SV_INITIAL_ROUND` to set the initial round. This change aims to better align TestNet with MainNet's ongoing state, particularly in terms of coin issuance.

This Canton Improvement Proposal (CIP 0067) authorizes a one-time allocation of historical unclaimed rewards from the Canton validator reward pool to the Global Synchronizer Foundation (GSF). The funds, estimated to be 1.6-1.7 billion CC, compensate GSF for its critical contributions to the Canton Network's design, governance, and operational stability. The transfer mechanism involves a manual review and verification process by the GSF Tokenomics Committee before sending the funds to the designated GSF address.

This Canton Improvement Proposal (CIP-0066) enables Super Validators to initiate a vote to authorize the minting of Canton Coin from an unclaimed reward pool, aligning with the milestone-based CIP rewards structure. The proposal introduces a new governance mechanism that allows Super Validators to propose the creation of `UnallocatedUnclaimedActivityRecord` contracts, representing authorized but not yet allocated Amulet rewards. This mechanism operationalizes the milestone-based CIP rewards structure and ensures decentralization, auditability, and escrow guarantees.

This CIP proposes adding Layer Zero, Wormhole, and Chainlink as Super Validators (SVs) with a weight of 3 each, alongside creating a bonus pool of weight 5. The purpose is to fairly compensate these bridge operators for their significant investments in engineering, testing, and security to connect to Canton, while also incentivizing early deployment and scaling. This mechanism aims to establish robust cross-chain connectivity for Canton, fostering a competitive environment among high-quality bridge solutions and potentially creating a "preferred" bridge through Canton Naming Service registration.

This Canton Improvement Proposal (CIP 0064) aims to replace the elected SV delegate mechanism with a delegateless automation system, improving fault tolerance and decentralization. The proposed system authorizes all Super Validators (SVs) to submit designated actions, with each SV application introducing a random delay to minimize contention. This change is expected to reduce unnecessary network load and improve overall system resilience.

This Canton Improvement Proposal (CIP 0063) adds Kaiko as a Super Validator of weight 6.5, contingent on milestones and deliverables being met over an 18-month period. Kaiko commits to building data solutions on the Canton Network, including making Canton activity data available off-chain and integrating real-world data to enhance network value. By partnering with Kaiko, the Canton Network aims to increase visibility, attract institutional-grade data, and support the development of its ecosystem.

This Canton Improvement Proposal (CIP-0062) outlines the process for synchronizer migration with downtime to upgrade from Canton 3.2 to Canton 3.3, requiring a major upgrade with downtime action by Super Validators and Validators. The upgrade procedure involves a synchronized operational procedure, pausing the synchronizer until completion, and has been tested extensively on DevNet, TestNet, and MainNet. The proposed upgrade is expected to complete within three hours and will be carried out on MainNet on June 25, 2025, with TestNet and DevNet upgrades scheduled for June 11 and May 28, 2025, respectively.
