MASS is an open-source Proof of Capacity (PoC) consensus algorithm proposed by top computer scientists from MIT. As the second-generation consensus technology succeeding Bitcoins Proof of Work (PoW), it successfully addresses the high energy consumption issues of Bitcoin and can provide underlying consensus support for any blockchain. Its innovation lies in the fact that each user only needs to contribute a small amount of space to participate in the storage and validation of blockchain data. Based on MASS, millions of spaces distributed globally will be connected into a super consensus machine, safeguarding blockchains as a public service.

The MASS blockchain system is the first public chain to utilize the MASS consensus engine. The MASS cryptocurrency serves as the value storage of the MASS blockchain system and the value anchor of the MASS consensus engine.

Project Introduction

To fundamentally solve issues such as centralization trends in the Bitcoin network, high energy consumption during consensus processes, and the inability to reuse network computing power, and with the aim of achieving a more democratic, fair, energy-efficient, secure, highly scalable, and universal blockchain infrastructure, the MASS community proposed and developed an efficient Proof of Capacity consensus protocol. When nodes participate in the MASS network to maintain data consistency, they only need to provide the network with a valid and non-forgable proof of capacity, which is solely related to the space capacity provided by the node and can be verified by any node.

The advantages of the MASS Proof of Capacity consensus protocol include:

Permissionless participation in data maintenance by nodes, security boundaries similar to Nakamoto consensus, a more decentralized evolution of the node network, no resource consumption required for block production rights competition, and the ability for the node network to concurrently support multiple blockchain instances.

The MASS consensus engine is universal and can provide consensus services for any number of public chains. Nodes use storage capacity to run the consensus protocol without permission. The MASS consensus engine is fair and energy-efficient, requiring very little computational resources, which means everyone has the opportunity to participate.

Token Distribution

Mining Rewards: 18.75%
Lockup Rewards: 18.75%
Game Theory Rewards: 62.50%

If the block-producing miner binds MASS, in addition to receiving the basic mining reward, the miner can also receive additional game theory rewards. If the block-producing miner does not bind MASS, the lockup reward pool can receive additional game theory rewards.

Release Rules:

The total circulation of MASS is 206,438,400 tokens, which will be issued over 15 epochs. When entering a new epoch, the block reward per block will be halved, and the length of the epoch will be twice that of the previous one. The first halving occurs at block height 13440. Once all MASS tokens have been issued (which will take over 600 years), transaction fees will become the incentive for people to continue supporting the MASS network.
