The Problem

Mining in Cryptocurrencies is Highly Centralized

More than 80% of mining power in Ethereum emanates from 5 mining pools. Similarly, the main 8 pools control the same fraction of mining power in Bitcoin.

Transaction Censorship and Single Point of Failure

Pools dictate the transaction sets in new blocks, not miners.
Pools are subject to continuous DDoS attacks. If a big pool goes down, the security of the network is significantly compromised.

Mining Solo is Difficult for Small Miners

High variance of returns, hard for users to plan economically. Decentralized mining pools for Bitcoin (e.g., P2Pool) exist, but are inefficient and not applicable to Ethereum.

Centralized Pools Take High Fees

to cover for their operation costs and gain profits.

The Solution

Decentralize Pools by Leveraging Smart Contracts

We essentially replace the centralized pool operators by smart contracts, which is run and managed in a decentralized way on the blockchain.

Mitigate Transaction Censorship Threat

Miners can propose their own sets of transactions.

Guarantee Low Variance

Although being decentralized, our pools can guarantee the same variance in payments as centralized pools.

Low Fees

The decentralized formation of SmartPool does not require any infrastructure to operate the pool.
SmartPool may take negligible to almost zero fees to maintain the pool front-end and to develop new features.

How It Works

We use Ethereum smart contracts to build a decentralized pooled mining protocol called SmartPool. Our solution implicitly replaces the centralized pool operator by network participants who run the Ethereum network.

SmartPool includes several novel data structures and design choices which make its protocol secure and efficient. Specifically, we devise a new mechanism to verify and record miners' contributions to the pool without centralized operators. SmartPool's efficient probabilistic verification drastically reduces both the number of messages and the costs to run the pool for miners. Using a novel data structure called the augmented Merkle tree, SmartPool's batched share submission and efficient payment scheme remove any incentive for submitting invalid batches.

Frequently Asked Questions

An efficient and decentralized mining protocol for existing cryptocurrencies based on Ethereum smart contracts.

Normal centralized pools are not ideal because of: centralization in mining (obviously), transaction censorship (e.g. mining empty blocks, black-listing transactions), and high fees.

SmartPool enables an efficient way to mine blocks in a decentralized manner between miners. Everyone can propose their own transactions in a block, thus eliminating the censorship on transactions. SmartPool requires negligible to no fees from miners.

We are excited about Proof of stake as much as anyone else, but it will take roughly one more year for PoS to come. Until PoS is officially rolled out, SmartPool is still relevant and makes mining in Ethereum much more decentralized.

The adoption of Ethereum based decentralized pools for other cryptocurrencies would increase Ether volume usage (as ZCash and Bitcoin miners would have to interact with the corresponding Ethereum contracts) and directly benefit Ethereum miners.

Ethereum first, ZCash and Bitcoin will be supported later if funding allows. We would also provide a generic interface to allow porting to almost all cryptocurrencies.

No. We have considered this option, and decided against it. SmartPool is a community project, not for profit. SmartPool will be run for-and-by the community.

We feel that having a separate token or currency associated with it may ultimately limit its adoption. SmartPool's goal is decentralization, and the best way to get there is to scale without creating auxiliary incentive structures around it.

We will still issue tokens for each donation though. The tokens are only to recognize donors' contributions to SmartPool, thus may or may not have financial values in the future.

If you are a miner, it is pretty straightforward. You just need to install an update to your miner software (which we provide) to interact with the contracts. More details will be released later on.

If you are not a miner but a cryptocurrency advocate, please consider donating to support the SmartPool development. SmartPool is a non-profit open source project.

No. It is technically impossible to use P2Pool solution for Ethereum. Moreover, our solution also performs better than P2Pool for other currencies.

  1. SmartPool leverages the security of Ethereum blockchain for its operation. Previous decentralized Bitcoin pools (e.g. P2Pool) used a separate side-chain which doesn't have as strong a backing infrastructure as Ethereum today.
  2. SmartPool's design scales ad-infinitum. In contrast, previous decentralized Bitcoin pools have a scalability bottleneck at even 1% of the Bitcoin mining scale.
  3. SmartPool is a versatile concept. It can support mining for more than one cryptocurrency. It is appealing both for Bitcoin (which has dominated by large mining farms) as well as for other cryptocurrencies like Monero and ZCash (which have many more solo miners).

We already have a proof of concept for a SmartPool-based mining pool for Bitcoin. We aim to build production-ready and compatible system so everyone can use and launch their own decentralized pools.

Depending on our funding, we plan to launch and maintain SmartPool-based pools for Ethereum and other cryptocurrencies too.

  1. Public crowdfund: 14 Jan 2017 (we ask for donations from the public).
  2. First beta pool for Ethereum (on testnet): late April 2017.
  3. First working pool for Ethereum: late May 2017.
  4. Other's pools: from June 2017 (depending on the funding status).

The SmartPool project is funded by the community and run by the community. Thus, we will do a crowdfund and ask for donations from the public. We are also applying for some dev grants like Ethereum Dev Grants or Wanxiang Blockchain Labs. We will keep updating our funding status.

Depending on how much we get, our promised deliverables vary as follows.

  1. Less than 5,000 ETH: Implement SmartPool for Ethereum and release all software as open source (i.e. under MIT license).
  2. 5,000 to 10,000 ETH: In addition to what we have promised, we will launch a decentralized pool for Ethereum and maintain it until Ethereum moves to proof of stake.
  3. More than 10,000 ETH: In addition to what we have promised, we implement SmartPool protocol for other cryptocurrencies (Bitcoin, ZCash and/or Monero) and possibly launch and maintain real pools for these cryptocurrencies.

  1. Pay to the devs (please check out our team).
  2. Equipment and other expenses: GPU renting, basic infrastructure, social media promotion, etc.
  3. Miners' subsidies. For example, we may give 5% bonus on shares until the pool attracts at least 10% mining power.

There is no financial benefit at the moment. Although we issue tokens for each donation, the tokens are only to represent contributions to SmartPool. Our first priority is to promote decentralized mining and have a running pool with significant hash power. Compensating token holders will be considered, but will not be our main focus.
