Jul 31, 2019 · 18 min read

Biweekly update 17th July — 31st July

Paradigm Team is delighted to welcome all the Orbsians! This company has been working remarkably good during the last two weeks. Orbs developers tried their best to solve the significant problems, and it’s worth saying that they were successful in it. In their recent R&D update, a substantial amount of enhancements was mentioned: improvements of Gamma; various stability and monitoring updates, design & implementation work on the Lean Helix consensus algorithm goroutine model; upgraded version of Nebula, Orbs’ node deployment tool, that currently supports Terraform 0.12; a list of the most essential metrics for guardians, validators and app developers was published — and this is just a tiny part of milestones reached. Orbs core contributors continue to explore the subject of privacy through zero-knowledge proofs, focusing primarily on trusted setup and key generation ceremony. The state of the Orbs Ecosystem can make every crypto-enthusiast happy. Besides, brand new Validator replenished the list of the Universe participants. Orbs experts are working on an architecture that enables to remove the need for due diligence of Validators and enables an open and competitive process. This competition should increase the security of the network and its usability.

Moreover, the latest version of the Orbs blockchain platform was released, and accepted by the network’s Validators. This version contains original features (not a hot-fix). They worked on tools, stability, Ethereum connection, and election contract. By the way, OKEX listed Orbs token and it is also supported by BitGo and Coinbase Custody. Social activity was mainly represented by Tal Kol, Orbs Founder, and Development celebrity. He discussed the importance of open-source with devops.com and had an in-depth interview with Coinboyspodcast. The community is lively and supportive. We are still thrilled about a partnership with Celsius Network. The number of subscribers in social networks is increasing (not a surprise, they are cool). Feast your eyes on Orbs’ progress with Paradigm!


Github metrics
  • Since the last R&D update, so much has happened — Come see for yourself what’s been going on behind Orbs dev via the link.
  1. Updates include improvements to Gamma, various stability and monitoring updates, design & implementation work on the Lean Helix consensus algorithm goroutine model and more.

In addition, the code now creates a one-off goroutine per Block Sync request, so that scanning blocks or reading chunks from disk will not block the Block Sync topic goroutine. Another PR, #1193, upgrades the Orbs platform to compile using Golang 1.12.6 (previously 1.11.x was used).

It is expected that the Lean Helix topic will not be blocked, as it will have a goroutine that deals with reading from the topic.

@noambergIL and Ido Zilberberg updated code in PR49, PR1202 to support Sign() becoming an external service — to that end, a cancellable Go context was added as a parameter to this method.

  • Use Cases and Dev Experience

Application Use Cases

A collection of use-cases with a media distributor to create a blockchain-based content registry (photos, videos etc.) and enable search, collaboration and monetization. Some interesting use-cases include:

  1. Smart contracts to register and search for registered images — including a perceptual hash search that finds images similar to provided ones

Document notarization — they’ve further developed the document notarization use-case, introducing encrypted fields, ownership and more. These concepts have been presented to multiple parties interested in blockchain-based document registration and notarization (https://github.com/orbs-network/notary).

Developer Experience

This is part of a larger SDK architecture change to enable experimental vs. stable, production-ready code, the team will expand on this subject and the rationale in a dedicated post.

  1. More documentation updates in regards to prism and the starter kit

User Facing Products

Prism (Block Explorer)

  1. Added a new script to automatically upgrade prims’s version, and publish it (commit).

  • Research and Architecturу

Orbs’ research efforts continue with researchers and developers work on different aspects of the Orbs blockchain infrastructure! Here is a breakdown:

PoS Research

Market research

Resources are dedicated to researching the PoS market. There are two sides to this market: Projects, and ecosystem players. On the projects’ side, Orbs researchers have been focused on learning ~20 different projects which have a PoS element to them. In particular, they’ve been trying to understand what goals were the projects trying to realize via specific design choices, and how ecosystem players eventually chose to respond. On the ecosystem players side, mapping the market to different types of players — staking services, infrastructure services, lending platforms, exchanges, etc to how each type may benefit/harm a PoS network.

Open and competitive validators nomination process.

Currently, Validators undergo a due diligence process in order to evaluate their technical abilities and enabling gradual rollout. Orbs architects are working on an architecture that enables to remove the need for due diligence and enables an open and competitive process. This competition, as a by-product, should increase the security of the network and its usability.

As a first step to achieve this, they are working on a locking contract for Validators and Validator candidates. This locking contract, deployed on Ethereum, is designed to match the Orbs election architecture and support efficient queries by the election contract that runs on top of the Orbs platform. In order to allow the protocol to evolve in the future, they’ve designed the contract to be migratable, while still requiring participants to provide their agreement for the migration.

  • Threshold BLS signature scheme security proof

An ongoing Random Beacon project is carried out by members of the research team. In this work, a set of rational players jointly perform a multiparty computation that results in a random number, that can be used in diverse applications. One such notable application is the selection of random committees in Orbs’ consensus mechanism.

A cryptographic primitive that naturally appears in this context, is ‘threshold digital signature’; the set of participants sign messages in an incorruptible manner as long as a large portion of them is honest. One manifestation of a threshold digital signature builds upon the well-known (single player) BLS signature scheme. However, security proof of the threshold version of this scheme is not covered in the literature. More specifically, the question raised is whether the devised scheme indeed holds the threshold property, meaning that a (certain specific) portion of players cannot produce a valid signature, while larger sets of players can. Orbs’ Research team has prepared a mathematical proof of security to ensure the security of the threshold version of the BLS signature scheme.

  • Zero-Knowledge

Orbs core contributors continue to explore the subject of privacy through zero-knowledge proofs, focusing primarily on a few subjects:

  1. Trusted Setup. Most efficient forms of zero-knowledge proofs require a trusted setup, a subject of controversy, as it entails an expensive procedure and is specified to an application. In other words, different applications (including updates to an application) require different trusted setups. They study zero-knowledge proof systems where the trusted setup only has to be carried out once and is universal in the sense that it supports all applications. These usually come at a price of efficiency, and they focus on mitigating this problem, taking advantage of the efficiency of the Orbs blockchain infrastructure.
  • File Systems and Immutable Large Data Storage

Orbs Network aims for accommodating apps that (among others) require large amounts of storage. Part of the research included the reviewing of the IPFS (InterPlanetary File System) protocol. IPFS is a distributed peer to peer storage system that has recently gained a lot of interest from various blockchain projects that see IPFS as a good candidate for their protocol’s storage layer (like TrueBit).

The research team has been scrutinizing the different components of IPFS in order to learn from them towards a solution tailored particularly for the purpose of the Orbs blockchain infrastructure.

Among these components are Distributed Hash Tables (DHTs) for fast content lookup and peer locating the network; GIT protocol for version control; block exchange protocol for data swapping marketplace — all may be relevant for the future design of the ever-evolving Orbs infrastructure.

The FileCoin protocol is designed to complement exactly that. The research team has recently focused on one of FileCoin’s most interesting innovations: Proof-of-Replication (PoRep). PoRep provides an entity with a way to prove that a specific number of replications of a particular file are stored in her local storage system. A distributed file system protocol that is able to absorb the overhead PoRep incurs can solve the problem of data availability, which is one of the major issues when dealing with vast amounts of storage.

  • This latest version of the Orbs blockchain platform was released, and accepted by the network’s Validators. The core team is very excited to publish the first version that contains actual features (not a hot-fix). Check it out via the link. While this is not a major update, it does include several mini-features and improvements based on requirements gathered from:
  1. Insights regarding the Orbs production network operating since March 2019

Main improvements:


  1. Bugfix: Following a case of a Validator Node being behind the network time, the core team added metrics reporting a node’s time vs. absolute time read with NTP to catch any time drifts of nodes. The metric is available to Validators and Guardians on the metrics page under “OS.Time.Drift.Millis” (pr #1163)

Election contract

  1. Bugfix: A bug wherein the vote-weight of the Guardians was not properly cleared before a new election result was calculated (bug #1227, pr #1234), was fixed.


  1. CI/CD: Improved and streamlined the nightly and Pull-Requests (PRs) processes. The goal is to have every PR as the last stage of testing to be deployed to a short-lived test-net and run tests and stress-tests on it.


  • Gamma now has more options:
  1. Override config values: Allow override of configuration variables from gamma-cli. This allows broader testing ability. (For example, using Ropsten as an Ethereum Node, closing blocks faster or slower, etc.)
  • Verification Mode: Verification Mode configuration now allows its operator the ability to run the transactions of the blocks (limited only to blocks that are “newer” than a certain time period) and thus not only verify execution, but also collect any std-output produced by the contract. This allows a certain kind of debug or verification process that was previously not available.

Ethereum connection

  1. Dialing every time so that recovery from fail and/or changes of node configuration (like DNS) can happen immediately. This prevents disconnect issues and stale connections.

Orbs Universe

Delegators, in order to receive rewards, you should delegate to an active guardian who does not miss voting deadlines. If your guardian misses voting deadlines, you will not get rewards in this period.

Guardians, please note that elections are every 20000 Ethereum blocks, it is approximately 3 days. A Guardian vote is valid for about 1 week. We recommend voting every 6 days to be on the safe side.

Voting deadlines calendar (estimated time)

Tools for Guardians: We launched specific delegation template for Guardians, so they can present themselves by deploying their own web-site using our instructions. Later, we are going to create other tools for the comfortable use.

This is how we use the Template to introduce ourselves: orbs.paradigmcitadel.io

Our GitHub with Template: https://github.com/paradigmcitadel/orbs_guardian_delegation

You can delegate your Orbs tokens via link. After the end of the closest voting period, you can check your rewards here.

What’s next?

According to the new Roadmap:

  1. Proof-of-Stake Core Infrastructure V2 — Implement the next version of the Orbs Proof-of-Stake architecture with various improvements making the existing implementation more efficient, easier to use and more powerful with the ability to rely on stronger incentives like locking.

2. Proof-of-Stake Ecosystem Tools — Create tools for participants in the Orbs PoS Universe. Validators will benefit from easier ways to keep their node healthy. Guardians will have better ways to measure Validators. Delegators will have easier ways to stake and observe network activity.

3. Orbs Audit Node — Audit nodes are important for network security. They allow any external participant (not necessarily a Validator) to verify that the network operation is correct. Audit nodes may choose to audit only a single or subset of virtual chains.

4. Orbs Two Tier Consensus — Two tier consensus is the hybrid aspect of Orbs. It allows to build permissioned apps — where the app can select its own block producers. These apps run over a permissionless infrastructure — where validators are selected by the network.

5. Virtual Chains Infrastructure — Virtual chains are a key feature of Orbs that provides isolation between apps. It gives the network infinite scalability and sharding; and provides apps with lower cost of operation, guaranteed resources and independent governance.

6. Validator Node Deployment V2 — The next generation of how a Validator deploys and operates an Orbs node. Improvements include efficiency for reduced operation cost, higher availability and uptime, optimizations for even more scaling and improved security.

7. Orbs Smart Contract SDK — Allow developers to build even better apps with Orbs for more versatile use cases. Developers are requesting richer API’s that support more languages, more powerful data structures and more flexible interoperability.

8. App Developer Experience — Increase developer adoption by making the app development experience on Orbs easier than ever. Help developers learn how to build on Orbs and give better developer tools to debug and test their smart contracts.

9. Ready-Made Use Case Templates — Increase business adoption of the Orbs network by offering solutions for popular blockchain use-cases. These templates reduce the integration time of blockchain technology into a business from months to days.

10. Network Production Enhancements — The Orbs network is in production mainnet from March 2019. Continue the process of making the network more mature, reliable stable, performant and secure — so it can host even bigger apps with more users and more value.

11. Protocol Enhancement Research — Long term research for core improvements to the Orbs protocol. Every big feature like privacy with zero-knowledge proofs requires months of academic research before being implemented in production and added to the core.

12. Online IDE for App Developers — Similar to Ethereum’s Remix, the online IDE lets app developers write smart contracts directly from their web browser without installing any tools. This is a great way to make experimentation with Orbs easier with less friction.

13. Prism Block Explorer — Prism is the Orbs block explorer which lets users access the chain directly, find transactions and inspect blocks. Prism is also a developer tool because it lets smart contract developers investigate their contracts and learn how they’re used.
