It aims to provide a digital cash solution accessible to everyone while protecting users\u2019 funds and data privacy. FIRO is the native token with a total supply of 21,400,000, following Bitcoin\u2019s same distribution model and 4-year halving cycle.<\/p>\n<p dir=\"auto\">The project\u2019s core philosophy is built on the principle of \u201cDon\u2019t trust, verify.\u201d It offers a system that safeguards individuals\u2019 financial freedom without relying on central authorities. The project stands out with both its technical and societal impact: the first practical implementation of Zerocoin, the Thai elections, and the initial integration of Dandelion++\u2014milestones that position Firo as a pioneer among privacy coins.<\/p>\n<p dir=\"auto\">The project is designed as a privacy-focused infrastructure. Bitcoin\u2019s transparency keeps users\u2019 transactions in a public ledger visible to all, which completely eliminates financial privacy. Firo was created to solve this problem cryptographically. Users can operate freely with hidden addresses, hidden amounts, and hidden transaction histories.<\/p>\n<p dir=\"auto\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-180894 aligncenter\" src=\"https:\/\/coinmuhendisi.com\/blog\/wp-content\/uploads\/2025\/11\/firo-1-1.png\" alt=\"\" width=\"1348\" height=\"628\" \/><\/p>\n<p dir=\"auto\">Additionally, the project prioritizes mining accessibility. Unlike Bitcoin, dominated by ASIC devices, Firo\u2019s FiroPoW algorithm enables mining with home GPUs. This keeps power decentralized and prevents mining from being monopolized.<\/p>\n<p dir=\"auto\">The project is not just a coin\u2014it is a privacy infrastructure. Other projects build upon Firo\u2019s research outputs (Zerocoin, Sigma, Lelantus). Monero\u2019s Triptych and Seraphis protocols, as well as Beam\u2019s Lelantus-MW, were inspired by Firo\u2019s innovations.<\/p>\n<p dir=\"auto\">Firo uses a Proof of Work (PoW) and Masternode hybrid consensus model. Block time is 5 minutes, and the block reward is 6.25 FIRO. With LLMQ Chainlocks, blocks are locked instantly, making double-spend attacks impossible.<\/p>\n<p dir=\"auto\">Lelantus Spark is Firo\u2019s most advanced privacy protocol:<\/p>\n<ul dir=\"auto\">\n<li>One-out-of-many proof: Does not reveal which coin was burned<\/li>\n<li>No trusted setup: Unlike Zcash, zero \u201ctoxic waste\u201d risk<\/li>\n<li>215+ anonymity set: Transaction vanishes among thousands of coins<\/li>\n<li>TEE + MPC TSS: Hardware-level security<\/li>\n<\/ul>\n<p dir=\"auto\">Dandelion++ provides network-layer privacy:<\/p>\n<ul dir=\"auto\">\n<li>Transactions propagate via random routing<\/li>\n<li>IP-to-transaction linkage blocked at 99.9%<\/li>\n<li>Resistant to Sybil attacks<\/li>\n<\/ul>\n<p dir=\"auto\">Spark Assets extends privacy to the token level:<\/p>\n<ul dir=\"auto\">\n<li>Token type is hidden<\/li>\n<li>Enables private voting, private DeFi, private NFTs<\/li>\n<\/ul>\n<p dir=\"auto\">Firo is a research-driven project. The team publishes academic papers and undergoes independent audits. The transition from Zerocoin to Lelantus is an example of turning a security vulnerability into an opportunity.<\/p>\n<p dir=\"auto\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-180897 aligncenter\" src=\"https:\/\/coinmuhendisi.com\/blog\/wp-content\/uploads\/2025\/11\/firo-2.png\" alt=\"\" width=\"982\" height=\"563\" \/><\/p>\n<h2 dir=\"auto\"><span class=\"ez-toc-section\" id=\"How_Does_Lelantus_Work\"><\/span>How Does Lelantus Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p dir=\"auto\">Lelantus is Firo\u2019s privacy engine. Built on zero-knowledge proof, this system allows users to erase their history and start fresh. The process works in the following steps:<\/p>\n<ol dir=\"auto\">\n<li>Coin Burning (Burn) The user permanently destroys their FIRO coins. This transaction confirms that the coins have been completely removed from the blockchain. Burned coins are irreversibly eliminated from the system.<\/li>\n<li>Zero-Knowledge Proof The user proves only that \u201cyes, I burned them\u201d without revealing which coins were burned. This is made possible through a special zk structure called one-out-of-many proof.\n<ul dir=\"auto\">\n<li>No trusted setup required<\/li>\n<li>No exotic math<\/li>\n<li>High anonymity set (mixes among 215+ coins)<\/li>\n<\/ul>\n<\/li>\n<li>New Coin Minting (Mint) The user receives completely new and history-free FIRO equal to the burned amount. These new coins have no connection to the old addresses.\n<ul dir=\"auto\">\n<li>Transaction size is also hidden<\/li>\n<li>Sender, receiver, and amount are fully anonymous<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p dir=\"auto\">This mechanism mathematically guarantees privacy. For example, if you burn 100 FIRO and receive 100 new FIRO, no one can prove the two actions are linked.<\/p>\n<p dir=\"auto\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-180900 aligncenter\" src=\"https:\/\/coinmuhendisi.com\/blog\/wp-content\/uploads\/2025\/11\/firo-3.png\" alt=\"\" width=\"1459\" height=\"551\" \/><\/p>\n<h2 dir=\"auto\"><span class=\"ez-toc-section\" id=\"Masternodes_Network_Security\"><\/span>Masternodes &amp; Network Security<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p dir=\"auto\">The project operates on a hybrid PoW + LLMQ system.
