BRICS
BRICS Pay: An accurate technical and strategic overview.
A comprehensive analysis of integration strategies between American digital payment systems and BRICS Pay:
Current State
BRICS Pay Architecture: BRICS Pay is a decentralized multi-currency blockchain-based payment system designed to facilitate cross-border transactions independent of SWIFT and the US dollar, operating through a decentralized autonomous organization (DAO) governed by smart contracts . The system must integrate with existing national payment platforms like India’s UPI and Russia’s Mir .
US Digital Infrastructure: The US has FedNow for real-time interbank settlements but no CBDC, with the Federal Reserve stating it would only proceed with a central bank digital currency with Congressional authorization . The Fed has fewer than 20 people working on digital currency compared to China’s 300+ .
Integration Architectures
1. Multi-Layer Bridge Protocol

└──────────┬──────────┘ └──────────┬───────────┘

└───────► Bridge Layer ◄────────┘
(Atomic Swaps/
HTLCs/Escrow)Technical Components:
Atomic Swap Protocols: Hash Time-Locked Contracts (HTLCs) ensuring trustless cross-chain transactions
Liquidity Pools: Decentralized market makers providing instant settlement
Oracle Networks: Price feeds for real-time currency conversion
Settlement Rails: Either direct blockchain settlement or correspondent banking hybrid
2. Correspondent Banking + DLT Hybrid
Traditional correspondent banking infrastructure augmented with distributed ledger technology for transparency and settlement finality. This resembles the “BRICS Bridge” concept - a multisided payment platform to improve the global monetary system .
Architecture:
US banks maintain correspondent relationships with BRICS member banks
Blockchain layer provides immutable settlement records
Smart contracts automate compliance and regulatory reporting
Private permissioned chains for institutional use, public chains for retail
3. Interoperable CBDC Framework
BRICS Pay will integrate with digital versions of national currencies like the digital ruble and yuan . A US digital dollar could connect through:
Technical Approaches:
ISO 20022 Messaging: Universal financial messaging standard both systems adopt
Polkadot/Cosmos-style Interoperability: Separate chains communicating via bridge protocols
Wrapped Tokens: Tokenized representations of USD on BRICS Pay blockchain, backed 1:1 by reserves
Gateway Nodes: Specialized validators maintaining state across both networks
4. Stablecoin Bridge Layer
Private sector stablecoins (USDC, USDT) as intermediary assets:
US Banking → Stablecoin → BRICS Pay → Local CurrencyAdvantages:
Already deployed infrastructure
Market-tested liquidity mechanisms
Regulatory frameworks developing in parallel
Lower political friction than government-to-government protocols
Strategic Models
Model A: Competitive Coexistence
Parallel systems with limited interoperability
Market forces determine usage patterns
API gateways for specific use cases (remittances, trade finance)
Minimal political coordination required
Model B: Controlled Integration
Bilateral agreements between US Treasury and BRICS members
Regulated bridge operators (like SWIFT cooperatives)
Tiered access based on compliance requirements
Enhanced monitoring for sanctions/AML enforcement
Model C: Universal Protocol Layer
New neutral protocol neither system controls
Similar to how TCP/IP enabled internet interoperability
Governed by international standards body
Both systems build adapters to common spec
Implementation Challenges
Technical:
Throughput Mismatches: Blockchain transaction processing must match existing payment system speeds
Finality Differences: FedNow provides instant finality; blockchain systems vary (probabilistic vs. deterministic)
Key Management: Secure custody of cryptographic keys across institutional boundaries
Disaster Recovery: Cross-system rollback and reconciliation mechanisms
Political/Economic:
BRICS Pay explicitly aims to reduce dollar dominance and bypass traditional financial gatekeepers
US sanctions enforcement becomes more complex with alternative rails
Currency volatility management across diverse economies
Governance disputes over protocol upgrades and rule changes
Regulatory:
Each country’s existing digital payment regulations must be compatible
Cross-border data sovereignty requirements
AML/KYC harmonization across jurisdictions
Legal recognition of smart contract execution
Practical Use Cases
Trade Finance: Letter of credit automation using smart contracts, with USD payment legs settling through US banks and yuan/rupee legs through BRICS Pay.
Remittances: Direct person-to-person transfers bypassing correspondent banking fees, with currency conversion at bridge layer.
Treasury Operations: Multinational corporations managing cash across regions with real-time visibility into both systems.
Commodity Trading: BRICS nations interested in settling commodity trades in local currencies rather than dollars - integration allows hedging and settlement flexibility.
Regenerative Infrastructure Context
Given the work on Univrs.io and mycelial economics, a decentralized bridge protocol governed by contribution-weighted voting would align well:
Bridge operators earn tokens based on transaction volume and uptime
Governance proposals for protocol upgrades require stake from both ecosystems
Revenue from fees distributed to infrastructure providers
Composable smart contracts allow anyone to build settlement applications
Zero-knowledge proofs preserve privacy while enabling compliance
The key technical challenge is asynchronous finality - US systems expect instant settlement while blockchain systems have varying finality guarantees. This requires sophisticated escrow mechanisms and possibly optimistic rollup-style constructions where disputes can be challenged within a time window.

Mycelial Credit system architecture.
Building a contribution-based, regenerative credit network that fundamentally reimagines creditworthiness. Abridge architecture that connects our system to BRICS Pay while preserving regenerative principles.
Bridge Architecture: CryptoSaint ↔ BRICS Pay
Core Challenge: Philosophy Translation Layer
Our system operates on regenerative contribution credits while BRICS Pay handles fiat currency settlements. The bridge must translate between these fundamentally different value systems without compromising either.

└─────────────────────────────────────────────────────────────────┘1. Credit Valuation Protocol (CVP)
This is the critical innovation layer - converting contribution-based credit into currency-exchangeable value.
Rust Implementation Structure:
// Core credit valuation types
pub struct CreditValuationProtocol {
reputation_oracle: ReputationOracle,
ecological_assessor: EcologicalImpactAssessor,
mutual_credit_ledger: MutualCreditLedger,
brics_bridge: BricsBridge,
}
pub struct ContributionCredit {
holder: AccountId,
reputation_score: u64,
ecological_impact: EcologicalMetrics,
mutual_credit_balance: Balance,
time_weighted_contributions: Vec<TimeWeightedContribution>,
bioregional_attestations: Vec<BioregionalAttestation>,
}
pub struct BridgeableCredit {
// CryptoSaint native representation
contribution_credit: ContributionCredit,
// Valuation for bridge
collateral_ratio: Ratio,
bridge_capacity: Balance,
risk_assessment: RiskScore,
// BRICS Pay compatibility
currency_equivalents: HashMap<BricsCurrency, Balance>,
settlement_terms: SettlementTerms,
}
impl CreditValuationProtocol {
/// Convert contribution credit to bridge-eligible value
pub fn assess_bridge_eligibility(
&self,
credit: &ContributionCredit,
) -> Result<BridgeableCredit, Error> {
// Multi-factor assessment
let reputation_factor = self.calculate_reputation_multiplier(credit)?;
let ecological_factor = self.assess_ecological_value(credit)?;
let community_trust = self.query_quadratic_consensus(credit)?;
// Composite creditworthiness
let bridge_capacity = self.compute_bridge_capacity(
reputation_factor,
ecological_factor,
community_trust,
credit.mutual_credit_balance,
);
// Generate currency equivalents using oracles
let currency_equivalents = self.calculate_currency_equivalents(
bridge_capacity,
&credit.bioregional_attestations,
).await?;
Ok(BridgeableCredit {
contribution_credit: credit.clone(),
collateral_ratio: self.determine_collateral_ratio(credit),
bridge_capacity,
risk_assessment: self.assess_risk_profile(credit),
currency_equivalents,
settlement_terms: SettlementTerms::default(),
})
}
}CVP Mechanics:
Input Variables:
Reputation score (from your DAO governance participation)
Verifiable ecological regeneration metrics
Mutual credit network position
Time-weighted contribution history
Bioregional community attestations
Output:
Bridge-eligible credit capacity (denominated in “Bridge Credits”)
Currency conversion rates to BRICS currencies (RUB, CNY, INR, BRL, ZAR)
Collateralization requirements
Settlement timeframes
Key Innovation: Your system doesn’t need 1:1 fiat backing because credit is time-released based on contribution velocity. Someone actively regenerating ecosystems has higher credit capacity than static capital holders.
2. Dual-Ledger Settlement Architecture
pub struct DualLedgerBridge {
// CryptoSaint side
substrate_chain: SubstrateClient,
credit_network: CreditNetworkState,
// BRICS Pay side
brics_adapters: HashMap<BricsCountry, BricsPayAdapter>,
cbdc_connectors: HashMap<Currency, CbdcConnector>,
// Bridge state
atomic_swap_registry: AtomicSwapRegistry,
escrow_accounts: HashMap<EscrowId, EscrowAccount>,
oracle_network: OracleNetwork,
}
impl DualLedgerBridge {
/// Execute cross-system credit transaction
pub async fn execute_bridge_transaction(
&mut self,
request: BridgeTransactionRequest,
) -> Result<BridgeTransactionReceipt, Error> {
// Phase 1: Lock CryptoSaint credit
let credit_lock = self.lock_contribution_credit(
&request.sender,
request.amount,
).await?;
// Phase 2: Oracle pricing
let exchange_rate = self.oracle_network.get_exchange_rate(
Currency::BridgeCredit,
request.target_currency,
).await?;
// Phase 3: Setup atomic swap
let swap_contract = self.create_htlc_contract(
credit_lock,
exchange_rate,
request.target_currency,
).await?;
// Phase 4: BRICS Pay settlement
let brics_tx = self.execute_brics_settlement(
swap_contract,
request.recipient,
).await?;
// Phase 5: Finalize or rollback
match brics_tx.status {
SettlementStatus::Confirmed => {
self.finalize_credit_burn(&credit_lock).await?;
Ok(BridgeTransactionReceipt::Success(brics_tx))
}
SettlementStatus::Failed => {
self.rollback_credit_lock(&credit_lock).await?;
Err(Error::BricsSettlementFailed)
}
_ => Err(Error::UnexpectedState)
}
}
}3. Atomic Swap Protocol with Ecological Backing
Traditional atomic swaps use HTLC (Hash Time-Locked Contracts). Your system needs Ecologically-Backed HTLCs (EB-HTLC):
pub struct EcologicallyBackedHTLC {
// Standard HTLC fields
hash_lock: H256,
time_lock: BlockNumber,
// CryptoSaint extensions
ecological_collateral: Vec<EcologicalAssetId>,
reputation_stake: ReputationStake,
community_guarantors: Vec<AccountId>,
// Bridge linking
cryptosaint_lock: CreditLock,
brics_settlement: BricsPaymentIntent,
}
impl EcologicallyBackedHTLC {
/// Create swap contract with regenerative backing
pub fn create(
credit_amount: Balance,
ecological_assets: Vec<EcologicalAsset>,
target_currency: BricsCurrency,
target_amount: Balance,
) -> Result<Self, Error> {
// Compute hash lock from both chains
let preimage = Self::generate_cross_chain_preimage()?;
let hash_lock = blake2_256(&preimage);
// Verify ecological collateral sufficiency
let collateral_value = Self::assess_ecological_collateral(&ecological_assets)?;
ensure!(collateral_value >= credit_amount * COLLATERAL_RATIO, Error::InsufficientCollateral);
// Setup time locks (different for each chain)
let cryptosaint_timelock = current_block() + SWAP_DURATION;
let brics_timelock = current_timestamp() + SWAP_DURATION_SECONDS;
Ok(Self {
hash_lock,
time_lock: cryptosaint_timelock,
ecological_collateral: ecological_assets.iter().map(|a| a.id).collect(),
cryptosaint_lock: CreditLock::new(credit_amount, cryptosaint_timelock),
brics_settlement: BricsPaymentIntent::new(
target_currency,
target_amount,
brics_timelock,
),
..Default::default()
})
}
}4. Oracle Network for Dynamic Pricing
A contribution-based credits need multi-dimensional oracles:
pub struct MultiDimensionalOracle {
// Traditional price feeds
currency_oracles: Vec<CurrencyPriceOracle>,
// Regenerative metrics
ecological_impact_oracle: EcologicalImpactOracle,
bioregional_value_oracle: BioregionalValueOracle,
reputation_aggregator: ReputationAggregator,
// Bridge-specific
bridge_liquidity_oracle: LiquidityOracle,
settlement_cost_estimator: CostEstimator,
}
impl MultiDimensionalOracle {
/// Calculate bridge credit to BRICS currency rate
pub async fn calculate_exchange_rate(
&self,
credit: &ContributionCredit,
target_currency: BricsCurrency,
) -> Result<ExchangeRate, Error> {
// Base rate from market oracles
let base_rate = self.currency_oracles
.get_median_rate(Currency::USD, target_currency)
.await?;
// Ecological premium calculation
let eco_premium = self.ecological_impact_oracle
.calculate_premium(&credit.ecological_impact)
.await?;
// Bioregional adjustment
let regional_factor = self.bioregional_value_oracle
.get_regional_multiplier(&credit.bioregional_attestations)
.await?;
// Reputation trust factor
let trust_multiplier = self.reputation_aggregator
.calculate_trust_factor(credit.reputation_score)
.await?;
// Composite rate
let adjusted_rate = base_rate
.multiply(Decimal::from(1) + eco_premium)
.multiply(regional_factor)
.multiply(trust_multiplier);
// Apply bridge costs and liquidity constraints
let final_rate = self.apply_bridge_adjustments(
adjusted_rate,
target_currency,
).await?;
Ok(ExchangeRate {
base_rate,
ecological_premium: eco_premium,
regional_factor,
trust_multiplier,
final_rate,
timestamp: current_timestamp(),
})
}
}5. Governance Bridge: DAO ↔ BRICS Consensus
A quadratic voting DAO needs to interface with BRICS Pay’s governance:
pub struct GovernanceBridge {
cryptosaint_dao: CommunityGovernance,
brics_consensus: BricsConsensusInterface,
bridge_council: BridgeCouncil,
}
pub struct BridgeProposal {
proposal_id: ProposalId,
proposal_type: ProposalType,
// Originates from which system
origin: GovernanceOrigin,
// Voting state in both systems
cryptosaint_votes: QuadraticVoteState,
brics_votes: Option<ConsensusVoteState>,
// Execution parameters
execution_threshold: VoteThreshold,
cross_chain_execution: bool,
}
impl GovernanceBridge {
/// Bridge a proposal between governance systems
pub async fn propose_cross_chain(
&mut self,
proposal: BridgeProposal,
) -> Result<ProposalId, Error> {
match proposal.origin {
GovernanceOrigin::CryptoSaint => {
// CryptoSaint DAO votes first
let dao_result = self.cryptosaint_dao
.execute_quadratic_vote(&proposal)
.await?;
// If approved and affects BRICS, forward to BRICS consensus
if dao_result.approved && proposal.cross_chain_execution {
self.forward_to_brics_consensus(proposal, dao_result).await?;
}
}
GovernanceOrigin::Brics => {
// BRICS consensus votes first
let consensus_result = self.brics_consensus
.vote_on_proposal(&proposal)
.await?;
// If approved and affects CryptoSaint, forward to DAO
if consensus_result.approved && proposal.cross_chain_execution {
self.forward_to_cryptosaint_dao(proposal, consensus_result).await?;
}
}
}
Ok(proposal.proposal_id)
}
/// Example: Adjusting bridge parameters
pub async fn propose_collateral_ratio_change(
&mut self,
new_ratio: Ratio,
rationale: String,
) -> Result<ProposalId, Error> {
let proposal = BridgeProposal {
proposal_type: ProposalType::CollateralRatioAdjustment(new_ratio),
origin: GovernanceOrigin::CryptoSaint,
cross_chain_execution: true, // Affects both systems
..Default::default()
};
self.propose_cross_chain(proposal).await
}

}7. Transaction Flow Example
Scenario: A bioregional cooperative in Brazil wants to pay an Indian regenerative agriculture project using CryptoSaint credits → BRICS Pay settlement.
1. Brazilian Cooperative (CryptoSaint Network):
- Has 10,000 contribution credits
- Reputation score: 850/1000
- Verified 50 hectares of forest restoration
2. Bridge Assessment:
├─ CVP evaluates creditworthiness
├─ Ecological Oracle values forest restoration premium: +15%
├─ Reputation multiplier: 1.85x
└─ Bridge capacity: 18,500 Bridge Credits
3. Conversion Request:
- Wants to pay 5,000 INR to Indian project
- Bridge Credit → INR rate (via oracles): 1 BC = 0.35 INR
- Required: ~14,286 Bridge Credits
- Cooperative has sufficient capacity ✓
4. Atomic Swap Execution:
├─ Lock 14,286 BC worth of contribution credits
├─ Ecological collateral: Forest restoration certificates
├─ HTLC timelock: 24 hours
└─ Hash: 0x7abc...
5. BRICS Pay Settlement:
├─ Bridge initiates BRL → INR settlement via BRICS Pay
├─ BRICS Bridge operator provides INR liquidity
├─ Settlement confirmed in BRICS Pay blockchain
└─ Preimage revealed: unlock collateral
6. Finalization:
├─ Contribution credits burned on CryptoSaint
├─ Indian project receives 5,000 INR via UPI
├─ Transaction recorded in both ledgers
└─ Reputation points awarded to cooperative8. Risk Management & Collateralization
pub struct RiskManagementEngine {
exposure_limits: ExposureLimits,
collateral_pool: CollateralPool,
insurance_fund: InsuranceFund,
}
pub struct ExposureLimits {
max_single_transaction: Balance,
max_daily_volume: Balance,
max_bridge_tvl: Balance,
per_user_limits: HashMap<AccountId, Balance>,
}
impl RiskManagementEngine {
/// Dynamic collateral ratio based on risk assessment
pub fn calculate_required_collateral(
&self,
credit: &ContributionCredit,
target_amount: Balance,
) -> Result<CollateralRequirement, Error> {
// Base ratio: 150%
let mut ratio = Ratio::from_percent(150);
// Adjust based on reputation (lower for high reputation)
if credit.reputation_score > 900 {
ratio = ratio * Ratio::from_percent(80); // 120% for saints
} else if credit.reputation_score < 500 {
ratio = ratio * Ratio::from_percent(120); // 180% for newcomers
}
// Adjust based on transaction size
if target_amount > self.exposure_limits.max_single_transaction {
return Err(Error::ExceedsExposureLimit);
}
// Ecological asset acceptance
let eco_collateral_value = credit.ecological_impact
.calculate_market_value(&self.collateral_pool.pricing_model)?;
Ok(CollateralRequirement {
total_required: target_amount * ratio,
contribution_credits: target_amount * ratio * Ratio::from_percent(60),
ecological_assets: target_amount * ratio * Ratio::from_percent(40),
eco_collateral_value,
})
}
}9. Liquidity Provision Mechanism
Since CryptoSaint credits aren’t directly tradeable for fiat, we need bridge liquidity providers:
pub struct LiquidityPool {
// Bridge operators stake both assets
cryptosaint_reserves: Balance,
brics_currency_reserves: HashMap<BricsCurrency, Balance>,
// LP token system
lp_tokens: HashMap<AccountId, Balance>,
total_lp_supply: Balance,
// Fee distribution
accumulated_fees: HashMap<BricsCurrency, Balance>,
}
impl LiquidityPool {
/// LPs provide BRICS currency liquidity, earn fees
pub fn add_liquidity(
&mut self,
provider: AccountId,
currency: BricsCurrency,
amount: Balance,
) -> Result<Balance, Error> {
// Calculate LP tokens to mint
let lp_tokens = if self.total_lp_supply == 0 {
amount // Initial provision
} else {
// Proportional to current pool
let reserve = self.brics_currency_reserves
.get(¤cy)
.unwrap_or(&0);
amount * self.total_lp_supply / reserve
};
// Update state
*self.brics_currency_reserves.entry(currency).or_insert(0) += amount;
*self.lp_tokens.entry(provider).or_insert(0) += lp_tokens;
self.total_lp_supply += lp_tokens;
Ok(lp_tokens)
}
/// Bridge transaction generates fees for LPs
pub fn collect_bridge_fee(
&mut self,
currency: BricsCurrency,
amount: Balance,
) -> Result<(), Error> {
let fee = amount * FEE_RATE; // e.g., 0.3%
*self.accumulated_fees.entry(currency).or_insert(0) += fee;
Ok(())
}
}10. Integration Strategy
Phase 1: Proof of Concept (3-6 months)
Single BRICS currency bridge (start with RUB or INR)
Limited transaction volume
Manual oracle updates
Centralized bridge operators
Phase 2: Multi-Currency Expansion (6-12 months)
All BRICS currencies supported
Automated oracle network
Decentralized bridge validators
Governance proposals for parameter adjustments
Phase 3: Full Decentralization (12-24 months)
Community-run bridge infrastructure
Zero trust atomic swaps
Integration with BRICS CBDCs
Cross-DAO governance
Key Technical Decisions
Use Substrate’s XCMP (Cross-Consensus Message Passing) for inter-chain communication
Deploy bridge as a parachain on Polkadot/Kusama if BRICS Pay adopts compatible tech
Implement TEE (Trusted Execution Environments) for sensitive oracle data
Use zero-knowledge proofs for privacy-preserving credit verification
Build redundant oracle networks - don’t rely on single data source
