# Overview  
  
Aleph Zero is a public [blockchain](https://iq.wiki/wiki/blockchain) that uses a custom algorithm leveraging [Directed Acyclic Graph (DAG) ](https://iq.wiki/wiki/directed-acyclic-graph-dag)technology to create an efficient and decentralized system. It improves upon current distributed ledger technologies by offering fast validation times, scalability, and enhanced security. The platform employs a "hub and spoke" model, allowing businesses to interact on a decentralized ledger while maintaining private networks. Aleph Zero demonstrated high performance in tests, achieving 416 millisecond validation times for 89,600 transactions per second using AWS [nodes](https://iq.wiki/wiki/node). The [blockchain](https://iq.wiki/wiki/blockchain) integrates [zero-knowledge proofs (ZKPs)](https://iq.wiki/wiki/zero-knowledge-proofs-zkps) and secure multi-party computation (sMPC) to ensure data security and privacy. Aleph Zero aims to enable SMBs and enterprises to communicate efficiently while benefiting from decentralization. [\[1\]](#cite-id-3hx10k0bs0o)  
  
# Technology  
  
## AlephBFT Consensus  
  
The code behind the Aleph Zero [blockchain](https://iq.wiki/wiki/blockchain) is Aleph[BFT](https://iq.wiki/wiki/byzantine-fault-tolerance), a peer-reviewed [consensus](https://iq.wiki/wiki/consensus-mechanism) protocol presented at the Advances in Financial Technologies (AFT) 2019 conference. Aleph Zero uses a modified [Proof of Stake (PoS)](https://iq.wiki/wiki/proof-of-stake) [consensus](https://iq.wiki/wiki/consensus-mechanism) algorithm alongside [Directed Acyclic Graphs (DAG)](https://iq.wiki/wiki/directed-acyclic-graph-dag). Like other [PoS](https://iq.wiki/wiki/proof-of-stake) [blockchains](https://iq.wiki/wiki/blockchain), a rotating committee of validators determines the [blockchain's](https://iq.wiki/wiki/blockchain) state. [DAGs](https://iq.wiki/wiki/directed-acyclic-graph-dag) enable faster transaction speeds, higher throughput, and significantly lower transaction fees, making the technology cost-effective and suitable for mass adoption.

## Shielder  
  
The Aleph Zero Shielder is a smart contract that leverages zk-SNARKs technology on Aleph Zero. It aims to facilitate private payments and interactions within [DeFi](https://iq.wiki/wiki/defi), contrasting with regular [blockchains'](https://iq.wiki/wiki/blockchain) transparency, allowing tracking of all user interactions. By utilizing zk-SNARKs, the Shielder enhances privacy by preventing third-party observers from linking different actions of the same user. This modular shielded pool allows for depositing and withdrawing PSP-22 tokens into a common shielded pool. Users within the Shielder are assigned secret identifiers called ZK-IDs. Additionally, it supports an optional Registrar responsible for registering new users by whitelisting their ZK-IDs and an optional Anonymity Revoker empowered to deanonymize specific users under special circumstances. The Shielder also facilitates shielded transfers securely, ensuring that transfers are only considered complete once claimed by the recipient. Furthermore, it supports ZK-plugins, which are auxiliary programmable logic modules that operate on secret data stored on shielded accounts. [\[3\]](#cite-id-6bibd6zw72)  
  
## MOST  
  
Introduced in September 2023, MOST is the bridge connecting Aleph Zero and [Ethereum](https://iq.wiki/wiki/ethereum), facilitating the seamless movement of external [liquidity](https://iq.wiki/wiki/pol-proof-of-liquidity) and [stablecoins](https://iq.wiki/wiki/stablecoin) to Aleph Zero while fostering [DeFi](https://iq.wiki/wiki/defi) growth on-chain. Designed for accessibility, MOST provides a user-friendly solution for asset transfers between [Ethereum](https://iq.wiki/wiki/ethereum) and Aleph Zero. As a guardian-based bridge, each guardian oversees two instances of the setup for [Testnet](https://iq.wiki/wiki/testnet) and [Mainnet](https://iq.wiki/wiki/mainnet), with eight guardians ensuring decentralization. Guardians wield governance keys for both networks, enabling actions like committee changes and contract upgrades. Key features include reduced fees for bridging native [ETH](https://iq.wiki/wiki/ethereum), [stablecoins](https://iq.wiki/wiki/stablecoin), and tokens from [Ethereum](https://iq.wiki/wiki/ethereum) to Aleph Zero, incentivizing [liquidity](https://iq.wiki/wiki/pol-proof-of-liquidity) attraction to the ecosystem. External audits will ensure the highest security standards upon completion. The name "MOST" originates from its meaning of "bridge" in several Slavic languages, including Polish, Czech, Slovak, Slovenian, Croatian, Serbian, and Bulgarian. [\[4\]](#cite-id-u55cfgtkj9a)  
  
## Liminal  
  
As an extension of Aleph Zero, Liminal enhances security and privacy while acting as a gateway to various [blockchains](https://iq.wiki/wiki/blockchain). It facilitates transactions between platforms linked to Aleph Zero, such as [Ethereum](https://iq.wiki/wiki/ethereum), [Near](https://iq.wiki/wiki/near-protocol), [Kusama](https://iq.wiki/wiki/kusama), [Cosmos](https://iq.wiki/wiki/cosmos), and [Binance Smart Chain](https://iq.wiki/wiki/binance-smart-chain). Liminal employs innovative security measures combining [zero-knowledge proofs](https://iq.wiki/wiki/zero-knowledge-proofs-zkps) (ZK-SNARKs) and Secure Multiparty Computation (sMPC). ZK-SNARKs enable one party to produce concise proof convincing another party of correct computations without revealing personal data. On the other hand, sMPC keeps sensitive information off-chain across multiple [nodes](https://iq.wiki/wiki/node), accessible only through a secure handshake. While ZK-SNARKs handle basic transfers, sMPC implements a global private state, such as [decentralized exchanges](https://iq.wiki/wiki/decentralized-exchange), ensuring that transaction values remain concealed. Liminal's hybrid approach ensures robust security and anonymity for client data. [\[5\]](#cite-id-nfjfktfllcl) $$widget0 [YOUTUBE@VID](X6CQnRl7QcI)$$  
  
## aScan  
  
aScan is a comprehensive token [explorer](https://iq.wiki/wiki/block-explorer) tailored for the Aleph Zero ecosystem, specifically focusing on PSP-22 tokens. PSP-22 is Aleph Zero's equivalent of the [ERC-20](https://iq.wiki/wiki/erc-20) standard on [Ethereum](https://iq.wiki/wiki/ethereum), enabling the creation of fungible tokens that are versatile, secure, and easily integrated into the ecosystem. By offering detailed insights into each PSP-22 token, including total supply, contract addresses, transaction history, and holder information, aScan ensures transparency for users and provides developers with a platform to effectively showcase their projects. The platform also provides real-time transaction updates, allowing users to monitor token movements and assess network health. [\[6\]](#cite-id-5c19lu3eaf7)  
  
# AZERO  
  
The AZERO coin follows an inflationary model, with an annual release of 30 million coins as [staking](https://iq.wiki/wiki/staking) rewards and an infinite predicted supply.  AZERO is the foundational currency within the Aleph Zero ecosystem, supporting various essential operations. Users can leverage AZERO to discount swap fees on the Common [Decentralized Exchange (DEXs)](https://iq.wiki/wiki/decentralized-exchange), reducing transaction costs. Additionally, it offers discounts on fees for asset-wrapping and usage of the Liminal Bridge, facilitating seamless asset transfers. Furthermore, AZERO is [collateral](https://iq.wiki/wiki/collateral) for wrapped assets in Liminal, enhancing [liquidity](https://iq.wiki/wiki/pol-proof-of-liquidity) and security. Moreover, users can engage in [validator](https://iq.wiki/wiki/validator) [node](https://iq.wiki/wiki/node) [staking](https://iq.wiki/wiki/staking), contributing to the network's stability and security while earning rewards. There's no mechanism to [burn](https://iq.wiki/wiki/token-burn) AZERO coins, but the ecosystem is open to implementing one as it evolves.

## Tokenomics  
  
Aleph Zero has allocated 23% of its tokens to the Aleph Zero Foundation and 10% to the team. The Foundation plans to allocate most of its tokens (approximately 70 million) towards research and development, marketing, operations, ecosystem incentives, and other expenses, with a significant portion reserved for the ecosystem fund. In later stages, the community will have a say in non-core spending from the treasury. [\[7\]](#cite-id-tyob8zj4f9)  
  
As for the team allocation, 80% of the coins will be locked for a year and vested over four years. During the pre-seed funding round of 2018, AZERO coins were distributed to contributors via Simple Agreement for Future Tokens (SAFT) at $0.04, with 50% unlocked at the Token Generation Event (TGE) and the rest vested for 15 months. The seed round saw 16,667% of coins distributed, with 71.42% unlocked at TGE and the remainder vested for 6 months. A special Early Community round distributed 5% of tokens, vested for 14-64 days after the mainnet launch. Finally, the public presale distributed 18.33% of the total token supply, with tokens vested for 12 months.
