Mintlayer’s Dynamic Slot Allocation (DSA) consensus merges Proof-Of-Stake and Bitcoin technologies to make decentralized financial markets attack-proof. Every block on Mintlayer anchors to a block on Bitcoin. Using the timespace of Bitcoin, each Mintlayer round lasts 1008 Bitcoin blocks, or a week. This frees Mintlayer from the dependency on external sources in time validation, solving PoS-based blockchain problems. The protocol’s checkpoint system protects Mintlayer against Proof-of-Stake long-range attacks, even in cases where a single participant can obtain more than 50% of the network. Any network participant can enforce checkpoints from Mintlayer on Bitcoin to ensure the network's irreversibility. To create and validate blocks, the protocol selects random stakers. This ensures that every user has an equally random chance of participation in the chain's maintenance, depending on the amount staked. Users can batch multi-token transfers into a single transaction to increase scalability. Block size is limited to 1MB, and signature aggregation reduces each payment's size by 70% to avoid network clogging. This ensures low transaction fees even at scale. Users create a transfer, opting in for peer-to-peer batching Signature aggregation compresses each payment to 1/3 of its weight Multi-token transaction is grouped with transfers from other users and then transmitted to the blockchain The transfer’s value is split across multiple receivers Users pay lower transfer fees and retain privacy, without network pollution The full spectrum of users, from institutional investors to beginner traders, benefits from Mintlayer’s wallet. In this non-custodial solution, users can access their funds from a hardware wallet or via private keys. Store or transfer any cryptocurrency or use existing wrapped tokens from any blockchains Redeem BTC on Bitcoin mainnet Run a node from any device Mintlayer connects tokens from different blockchains into an interconnected ecosystem. The protocol supports security tokens, asset tokenization, derivatives, and more, so users can choose their preferred type of investment. Migrate tokens from widely-adopted blockchains Build decentralized, all-inclusive applications Issue a token without technical knowledge The protocol runs a built-in DEX. Being native, it supports atomic-swap and is a censorship-resistant exchange. Users can verify their identity from the wallet application and get cleared through the Access-Control-List to access Security token trades. Share orders & initiate trades without 3rd-party intermediaries Exchange Bitcoin cross-chain directly on Mintlayer Trade any assets directly from the wallet Mintlayer is compatible with: Bitcoin lightning network Native multisignature BIP32, BIP38 and BIP174. Hardware wallet integration for private keys UTXO structure Developers who integrate with or build on top of Mintlayer get access to a simple API, supportive documentation, RFC, and an importing tool for ERC20 tokens from the Ethereum blockchain. Open-source development is incentivized with community grants. Transactions made on Mintlayer do not take up space on the Bitcoin blockchain. Network security checkpoints take up as much space as an average Bitcoin transaction — these are used to prevent attacks from entities with large stakes. Benefit from built-in P2P atomic swap exchange. Trade assets on Mintlayer or trade Bitcoin on its native chain. Use built-in decentralized tools for fundraising on primary and secondary markets—access-control-list compliant. Lightning Network compatibility allows stablecoin use to provide users with faster and cheaper transactions. Protect assets under private keys. Mintlayer’s single wallet stores all cryptocurrencies, security tokens, and collectibles. Turing incomplete smart contracts provide reliability and outcome predictability for dApps. Supports tokenomic models of taxation, dividend distribution, and others. UTXO’s inherent structure, combined with transaction batching, shuffles payment and balance history to make transactions anonymous. Supports complete anonymity with ‘Confidential Transaction’ mode. The main goal of the Mintlayer sidechain is tokenization. The native token represents the stake of the blocksigners: a) the ownership of the slots and b) the economic incentives to properly run the chain. Technically speaking, a difference between Bitcoin and Mintlayer transactions is, for the latter, the possibility of an Access Control List which allows for whitelisting/blacklisting the destination addresses or to create spending/receiving conditions (for example, that address can receive at most 100 tokens, or cannot spend before 1000 blocks). It is a core feature of the security tokens, which guarantees more compliance to legal requirements. ACLs today are possible on Ethereum, but not on Bitcoin. Not all Bitcoin miners are expected to do merged mining, so the players with an active role in the governing of the sidechain would be a subset of the Bitcoin miners. This centralizes the government of the sidechain in the hands of a few Bitcoin mining pools, handing the power to the mining-controllers of the pool, not the miners themselves.Financial markets no longer have to choose between

We want you to ask questions.
What is the benefit compared to Ethereum?
What is the benefit compared to Bitcoin?
Why not merged mining?
In case of a malicious pool in the Bitcoin ecosystem, the individual miners are likely to move the hash rate to a different pool, while a Bitcoin miner has no direct incentives in avoiding a pool that is acting maliciously on the sidechain. Hence, in a merged mining system there are no economic incentives preventing a possible attack on the sidechain from a Bitcoin pool. Additionally, even if the miners had control, they might have no interest in the well-being of the sidechain, if they aren't invested in it in the first place.
