Distributed systems

Distributed systems are, broadly speaking, networked systems whose components are located in different nodes that communicate and coordinate to achieve the system’s purpose. Distributed systems are at the very core of what we do and our interests extend across the entire field. In recent times, we have focused our efforts in the topics of consensus protocols, content-addressed networking, decentralized markets, and distributed data structures.

A finality calculator for Filecoin’s Expected Consensus
We propose a finality calculator for Filecoin’s Expected consensus that considers what takes place during epochs and can attain, under normal operating conditions, an error probability of 2^(−30) in 30 epochs (15 minutes) - a 30x improvement over the current 900-epoch threshold.

Security analysis of Filecoin's Expected Consensus in the Byzantine vs honest model
Filecoin is the largest storage-based open-source blockchain, both by storage capacity (>11EiB) and market capitalization. This paper provides the first formal security analysis of Filecoin’s consensus (ordering) protocol, Expected Consensus (EC).

Base fee manipulation in Ethereum's EIP-1559 transaction fee mechanism
In 2021 Ethereum adjusted the transaction pricing mechanism by implementing EIP-1559, which introduces the base fee - a fixed network fee per block that is burned and adjusted dynamically in accordance with network demand.

Generalized Impact Evaluators
Existing funding systems fail to sufficiently fund public goods and common goods due to insufficient mechanisms for coordinating various agents towards valuable outcomes. Relative to traditional capital systems that scalably organize activity around maximizing financial performance, impact funding remains underdeveloped, especially in the ability to reward high-upside, high-uncertainty work.

Enriching Kademlia by partitioning
Decentralizing the Web is becoming an increasingly interesting endeavor that aims at improving user security and privacy as well as providing guaranteed ownership of content. One such endeavor that pushes towards this reality, is Protocol Labs’ Inter-Planetary File System (IPFS) network, that provides a decentralized large scale file system to support the decentralized Web.

Pikachu: Securing PoS blockchains from long-range attacks by checkpointing into Bitcoin PoW using Taproot
Blockchain systems based on a reusable resource, such as proof-of-stake (PoS), provide weaker security guarantees than those based on proof-of-work. Specifically, they are vulnerable to long-range attacks, where an adversary can corrupt prior participants in order to rewrite the full history of the chain.

To the InterPlanetary File System – and beyond!: Peer-to-peer file sharing would make the Internet far more efficient
When the COVID-19 pandemic erupted in early 2020, the world made an unprecedented shift to remote work. As a precaution, some Internet providers scaled back service levels temporarily, although that probably wasn’t necessary for countries in Asia, Europe, and North America, which were generally able to cope with the surge in demand caused by people teleworking (and binge-watching Netflix).

State machine replication scalability made simple
Consensus, state machine replication (SMR) and total order broadcast (TOB) protocols are notorious for being poorly scalable with the number of participating nodes. Despite the recent race to reduce overall message complexity of leader-driven SMR/TOB protocols, scalability remains poor and the throughput is typically inversely proportional to the number of nodes.

Hierarchical consensus: A horizontal scaling framework for blockchains
We present the Filecoin Hierarchical Consensus framework, which aims to overcome the throughput challenges of blockchain consensus by horizontally scaling the network. Unlike traditional sharding designs, based on partitioning the state of the network, our solution centers on the concept of subnets –which are organized hierarchically– and can be spawned on-demand to manage new state.

Private attacks in longest chain proof-of-stake protocols with single secret leader elections
Single Secret Leader Elections have recently been proposed as an improved leader election mechanism for proof-of-stake (PoS) blockchains. However, the security gain they provide has not been quantified. In this work, we present a comparison of PoS longest-chain protocols that are based on Single Secret Leader Elections (SSLE) - that elect exactly one leader per round - versus those based on Probabilistic Leader Elections (PLE) - where one leader is elected on expectation.

Power fault tolerance
Byzantine Fault Tolerance (BFT) accounts for faults as the number of faulty nodes and is thus cumbersome to apply to many modern decentralized systems. We introduce the Power Fault Tolerance (PFT) model, which reframes BFT in terms of participants’ influence over the outcome of a protocol, instead of the number of nodes.

Proof of replication
We introduce Proof-of-Replication (PoRep), a new kind of Proof-of-Storage, that can be used to prove that some data D has been replicated to its own uniquely dedicated physical storage. Enforcing unique physical copies enables a verifier to check that a prover is not deduplicating multiple copies of D into the same storage space.

Filecoin: A cryptocurrency operated file storage network
Filecoin is a distributed electronic currency similar to Bitcoin. Unlike Bitcoin’s computation-only proof-of-work, Filecoin’s proof-of-work function includes a proof-of-retrievability component, which requires nodes to prove they store a particular file. The Filecoin network forms an entirely distributed file storage system, whose nodes are incentivized to store as much of the entire network’s data as they can.

Announcing RFP-014: The one with private retrieval
Can we speak privately? Unfortunately, our current options for private communication are limited, hamstrung by their reliance on a single-trusted-origin data publication model, high latencies, and security vulnerabilities. We think it is possible to design a scalable system that doesn’t sacrifice latency for privacy.

The Pikachu RFP: Checkpointing Filecoin onto Bitcoin
Blockchains based on a reusable resource (such as proof-of-stake or proof-of-space) are not as secure as those based on proof-of-work. Specifically, they are vulnerable to long-range attacks (LRA), where an adversary can create a long fork very cheaply.

New open problems in private data retrieval
tl;dr: We’d like to develop additional protocol-compatible primitives allowing users to interact privately with Web3 content. Central to the Web3 vision of an open, permissionless, and decentralized internet is the ability of parties to interact directly and privately with each other while retaining ownership of their data.
