CCCPSM01 1. Council Nodes Background Council Nodes perform critical validation and settlement functions in the Chain, including ordering transactions, executing transaction settlement, and rewarding CRO to network participants. We expect the Chain to reach the following number of Council Nodes: ● Within 5 years: 500 ● Within 10 years: 1,000 To optimize performance of the Chain, a smaller set of Council Nodes may be selected randomly to operate on the network during each epoch. Council Nodes will be rewarded for their services on a per transaction processed basis to ensure there is no prioritization and validation bias towards higher value transaction. Need for review We are proposing to require Council Nodes to continuously stake 50,000,000 CRO to perform their role in the network. Participants will have the ability to create staking pools in order to reach the required amount for staking. We are proposing that Council Nodes be rewarded 20% of the total pool allocated for rewards1. 2. Acquirer Nodes Background Acquirer Nodes are instrumental in connecting merchants and customers on the Chain, in particular they are responsible for authorizing transactions and settling on behalf of others. 1 Total pool allocated for rewards is composed of the following key components: a) Secondary Distribution and Launch Incentives Pool (from 10-50%), distribution across 5 years; b) Network Long-term Incentives Pool (100%), distribution to start after the Secondary Distribution and Launch Incentives Pool is depleted, 1/20th of the pool the first year and decreasing after that; c) Settlement Agent Levy (100%) 3

CCCPSM01 We expect the Chain to reach the following number of: ● Within 5 years: ○ Number of Merchants: 5,000,000 ○ Merchant Acquirer Nodes: 200 ○ Number of Customers: 25,000,000 ○ Customer Acquirer Nodes: 500 ○ Customer Yearly Spend: 1,000 USD ● Within 10 years: ○ Number of Merchants: 10,000,000 ○ Merchant Acquirer Nodes: 500 ○ Number of Customers: 100,000,000 ○ Customer Acquirer Nodes: 1,000 ○ Customer Yearly Spend: 2,000 USD Acquirer Nodes will be rewarded for their services on a per transaction amount processed basis to foster high volume of transactions in the network. Customer Acquirer Nodes will control the exchange rate between the crypto chosen by their customer for payment and the CRO to be sent over the Chain network. This will create a meaningful additional revenue stream for Customer Acquirer Nodes. Customers choosing to pay with CRO directly will transact with minimal fees. Merchant Acquirer Nodes will be required to have a 90-day rolling reserve2 to help cover potential financial risk, such as payment reversals you may receive like claims. The rolling reserve will be kept in CRO but fully hedged to remove any price volatility risk for the merchant. Need for review We are proposing to require Acquirer Nodes to continuously stake the following to perform their role in the network: ● Merchant Acquirer Nodes: 5,000 CRO per merchant supported ● Customer Acquirer Nodes: 5,000,000 CRO We are proposing that Acquirer Nodes be rewarded 80% of the total pool allocated for rewards, split: ● 60% for Customer Acquirer Nodes ● 20% for Merchant Acquirer Nodes 2 A rolling reserve is a reserve where the Chain network holds a percentage of each transaction a merchant receives each day, and then release it later on a scheduled basis 4

CCCPSM01 We are proposing that Merchant Acquirer Nodes rolling reserve will be set at 10%. 3. Community Nodes Background Chain enables customers and merchants who would like to transact directly, or any participants who would like to scrutinize the network, to set up Community Nodes with the ability to read data on the network and settle for one-self. We expect the Chain to reach the following number of Community Nodes: ● Within 5 years: 250,000 ● Within 10 years: 1,000,000 Community Nodes will be able to use the network free of charges. Need for review We are proposing to require Community Nodes to continuously stake 1,000 CRO to perform their role in the network. 4. Settlement Agents Background Cryptocurrency asset class is nascent and volatile. Merchants are however looking for price stability to manage and forecast their business. To increase cryptocurrency acceptance with merchants, it is key to be able to provide them with price stable conversion post-settlement options. Settlement Agents will perform this key service via CRO currency conversion to currencies deemed stable. We expect the Chain to reach the following number of Settlement Nodes: ● Within 5 years: 20 ● Within 10 years: 100 Settlement Agents will be allowed to generate profit by providing conversion services from CRO to coins deemed stable. They will also be allowed to charge 0.50% for fiat payouts to merchants. Settlement Agents will be charged by the network a levy and a portion of this levy will be used to reward network participants and ensure long-term sustainability of the protocol. 5

CCCPSM01 Need for review We are proposing to require Settlement Agent Nodes to continuously stake 500,000,000 CRO to perform their role in the network. We are proposing to set the Levy on Settlement Agent Nodes revenues at 25%. 6
