Product structure and supported assets

Braiins (Slush Pool)

Braiins functions as a dedicated Bitcoin proof-of-work mining pool coordinator and specialized mining software ecosystem, operating continuously since its inception as Slush Pool. Rather than providing custodial brokerage services, trading execution, or consumer cloud mining contracts, the platform aggregates computational hashrate from physical ASIC hardware worldwide to discover valid Bitcoin blocks. Valid share contributions from connected miners are recorded and rewarded proportionally according to platform scoring rules. The primary focus of the pool infrastructure remains Bitcoin mining, delivering specialized infrastructure designed specifically for ASIC operators.

In addition to mining pool coordination, the company develops Braiins OS, an aftermarket Linux-based operating system engineered for mainstream ASIC models such as various Antminer series devices. The firmware utilizes advanced per-chip autotuning algorithms to calibrate voltages and operating frequencies dynamically, optimizing energy efficiency and total computational performance. Hardware operators can observe real-time telemetry metrics, including chip temperatures, individual worker hashrates, and fan speeds, through responsive web dashboards, mobile applications, or custom telemetry endpoints designed for integration into enterprise mining management platforms.

koinx

KoinX functions primarily as an automated accounting and compliance engine for cryptocurrency portfolios. The software aggregates historical trade activity across a broad selection of centralized exchanges, self-custody wallet addresses, and decentralized finance protocols. Users can connect accounts using automated read-only API synchronizations or by uploading standardized spreadsheet records. Once imported, the internal ledger normalizes cross-platform transfers, recognizing internal wallet movements to prevent false taxable event triggers.

The platform supports diverse asset classes, ranging from spot cryptocurrencies and stablecoins to non-fungible tokens, wrapped tokens, and liquidity pool positions. In addition to basic buy and sell transactions, KoinX categorizes income-generating events such as mining yields, staking rewards, decentralized lending interest, hard forks, and airdrops. Portfolio analytics dashboards provide real-time valuation metrics, cost basis summaries, and unrealized gain or loss projections across all connected venues.

For tax preparation, the system generates comprehensive summary schedules and itemized reports aligned with specific national tax frameworks, including capital gains summaries, business income allocations, and tax-deductible expense ledgers. Professional accounts allow tax consultants and accountants to manage multiple client files from a unified administrative console, streamlining data audits and custom rule configurations.

Fee structure, scoring rewards, and settlement

Braiins (Slush Pool)

Braiins maintains a transparent fee structure centered on a baseline 2.0 percent pool fee for standard Bitcoin mining participation. Mining operations that deploy Braiins OS autotuning firmware on compatible ASIC machines receive a complete fee waiver, lowering the effective pool fee to 0.0 percent. This pricing structure offers significant cost savings for operators managing large hardware fleets. Mining revenue is calculated using a score-based distribution system, which dynamically weights submitted shares according to time elapsed within each block round to prevent pool hopping while mitigating luck variance across extended operating cycles.

Payout mechanics give miners complete control over settlement parameters by allowing custom balance thresholds denominated in BTC. Operators designate their preferred non-custodial wallet addresses directly in the web control panel, ensuring rewards automatically sweep on-chain whenever accumulated earnings meet the chosen limit. This automated settlement model prevents excessive custodial accumulation of miner balances on pool servers. Users can schedule payouts or adjust balance thresholds to account for prevailing Bitcoin network transaction fees, helping manage network settlement costs during periods of elevated mempool congestion.

koinx

KoinX operates on a tiered annual software subscription model based primarily on the total number of transactions processed within a given tax year. The platform frequently offers entry-level or free tiers designed for casual investors with minimal annual transaction volume, allowing users to test interface features and verify wallet connections before purchasing a full reporting package.

As trading activity increases, users transition into paid tiers that accommodate higher transaction thresholds, extending from hundreds of trades to tens of thousands of complex records. Higher subscription tiers typically unlock advanced reporting exports, priority customer assistance, multi-year historical data retention, and professional accounting review features. Because subscription pricing is tied directly to volume, high-frequency bot traders and active decentralized finance users must calculate their expected transaction counts to budget accurately.

Payment for software licenses is conducted through standard fiat payment channels, digital wallets, or payment gateways depending on the user's geographic region. The software does not take custody of trading balances, charge exchange spreads, or impose asset withdrawal fees, as all underlying trade settlements remain strictly within the user's independent exchange accounts or self-custody wallets.

Account security, non-custodial payouts, and protocol design

Braiins (Slush Pool)

Account security within the Braiins ecosystem focuses on helps protect user management dashboards and preventing unauthorized alterations to outbound payout destinations. User profiles support time-based one-time password two-factor authentication, granular API key permissions, and strict withdrawal address whitelisting. Whenever an operator modifies an external settlement address or alters payout parameters, the system triggers mandatory cooldown periods and email verification alerts. Because Braiins acts as a non-custodial mining coordinator, user funds remain on the platform only until accumulated mining earnings satisfy the automated withdrawal threshold configured by the account holder.

At the network transport level, Braiins actively develops and integrates Stratum V2, a modernized communication standard for proof-of-work mining systems. Stratum V2 introduces native cryptographic encryption that protects mining telemetry from interception, eavesdropping, and unauthorized hashrate hijacking across public internet paths. Furthermore, Stratum V2 incorporates advanced job negotiation mechanisms that enable individual miners to select their own transaction sets and construct custom block templates, reducing reliance on centralized pool servers for transaction selection and strengthening broader network decentralization.

Data protection and account privacy are critical components of the KoinX operational model. The platform is entirely non-custodial, meaning it never requests access to private keys, seed phrases, or exchange withdrawal permissions. When connecting centralized exchange accounts, users generate read-only API keys that strictly permit transaction history and balance retrieval, eliminating external fund movement capabilities from the tax application.

On the network infrastructure side, KoinX utilizes modern encryption standards to protect personal data and transaction records both in transit and at rest. Account authentication incorporates multi-factor authentication protocols to reduce unauthorized access risks. Data synchronization protocols are regularly updated to helps support secure communication with third-party exchange endpoints and public blockchain explorers.

While KoinX maintains rigorous operational data controls, users remain responsible for maintaining the confidentiality of their login credentials and configuring API restrictions accurately. Revoking API permissions or deleting uploaded transaction logs can be executed directly within the platform settings, giving account holders granular control over their retained financial data and historical audit trails.
