Description

The Proof of Reserves Kit serves as a verification tool for reserves, catering to cryptocurrency exchanges, brokers, and custodians that require verification for customer balances or reserve audits. It allows the importation of liability balances through various methods such as CSV files, read-only SQL queries, or internal HTTP endpoints, which are then compiled into a Merkle sum tree. The application verifies wallet balances declared on EVM networks, TRON, Bitcoin, Solana, and XRP Ledger at specific block or ledger positions, accommodating Bitcoin HD wallets via their extended public keys. Additionally, it utilizes read-only connectors to gather balances from Fireblocks vaults and both Binance spot and funding accounts. The software not only authenticates wallet-ownership signatures but also generates daily snapshots that are Ed25519-signed, along with auditor reports and CSV annexes available in both English and Turkish. Users have the capability to verify individual inclusion proofs via a dedicated branded verification page. The service can be accessed either as a BitPolaris-hosted solution or installed directly on customer servers, ensuring that it neither holds any keys nor facilitates fund transfers. This dual accessibility enhances its flexibility for various operational frameworks within the cryptocurrency ecosystem.

Description

Opendime is a compact USB device that enables you to use Bitcoin in a way similar to cash. You can easily transfer it to others, and by connecting it to any USB port, you can view the current balance. At any moment, you have the option to unseal it for online transactions, ensuring that you do not have to place your trust in anyone else. It functions like a read-only USB drive and is compatible with all computers, laptops, and smartphones. Inside, you'll find a QR code and text files that provide your Bitcoin address along with useful information. When you give an Opendime to someone, they can rest assured that you cannot reclaim the funds later, as the private key resides solely within the device. This key is generated internally and remains unknown to anyone, including yourself. This is the essence of physical Bitcoin: simply hand it over, and the recipient possesses it fully. You can pass it on multiple times, making transactions as effortless as a handshake. Without any miner fees or confirmation delays, Opendime allows for seamless exchanges. While the Bitcoin landscape evolves rapidly, Opendime is anchored in the core principles of Bitcoin that have remained constant for the past five years, solidifying its value as a reliable tool for digital currency. Furthermore, its user-friendly design makes it accessible for both novices and seasoned Bitcoin users.
