We help corporate, public and not-for-profit sectors to conceptualise blockchain solutions,
to implement blockchain infrastructure, to develop smart contracts and distributed apps, and to boost
community building.
The Teloscope has its own physical infrastructure dedicated to the production of blocks based on bare-metal servers, hosted in TIER III grade datacenters and maintained 24x7 by the staff
of The Teloscope.
The Teloscope BP service has been with 3 clear goals in mind: security, high availability and
scalability. The modular architecture, with redundant elements, allows The Teloscope to achieve
these goals:
2 physically independent 1Gbps Internet data accesses.
Double perimeter firewalls for access restriction and protection against DDoS attacks.
Additional local firewall in each of the nodes.
Smart Proxy for advanced load balancing ( automatic retries, circuit breaking, global rate
limiting, request shadowing, local zone load balancing, etc.) between the Block Producing Node
and the Full Node that act as redundancy.
Complies Level 5 of Telos suggested architecture: 2 x Full Node + 1 Block Producer + 1 Seed
Node + 1 x Backup.
Servers Location
The solution is located in a datacenter in Madrid, Spain. This telco-grade
datacenter, where The Teloscope team has several racks and semi-racks has all the required elements
for deploying a high-availability solution:
Security system: video-surveillance, access control, security guards, etc.
Fire Detection and Suppression Systems.
24-Hour Security
Uninterrupted Power Supply (UPS) systems and backup generator.
Redundant data access.
Redundant LAN network.
Remote hands for fast deployment or replacement of hardware.

Scaling Plans
The initial sizing of the hardware exceeds the current processing
requirements. However, the mechanisms that allow to increase the processing capacity at any time of
the network life cycle without interruption of the block production service have been foreseen,
allowing The Teloscope to adapt to the growing demand of the network:
The 24x7 monitoring of hardware and processes allows planning the need for hardware scaling
sufficiently in advance.
N + 1 redundancy allows disconnecting one of the nodes for expansion or even complete
replacement (scale up), without interrupting the service to the community. By repeating
this process, the processing capacity of the block producer can be easily scaled without service
interruption.
Testing Facilities
The Teloscope works continuously to improve the service it provides to the community. This
includes testing new solutions and performance improvements related to block production nodes.
These tests are performed on an environment fully independent of the production infrastructure,
running on servers owned by The Teloscope.
Using an advanced proxy allows diverting a replica of the actual traffic to the
pre-production environment without affecting the BP, making The Teloscope able to test at any time
a potential improvement with real data in an environment physically independent of the productive
one.
Tools & Projects
Discover Our Work.
We think that our work speaks for itself, so let us introduce you to some of our most recent
creations:
Chainspector
The Swiss Army Knife of Telos
This web application sumarizes several live informations about the Telos Blockchain network.
Although raw data is public, giving it a meaninful sense can be difficult for non technical users. It
can even be tedious for people using a block explorer. Unlike a block explorer, Chainspector offers a
set of tools that present useful information so the user can play with it.
On its very first version, the application offers four sets of tools. But with your feedback we
expect to add many more. Future development of chainspector will align with what the community needs.
You can shape our development!
The Teloscope Bot is a third-party application that runs inside the messaging app Telegram. Users
can interact with The Teloscope Bot by sending messages and commands to it by opening a chat with it.
Here is a list of the bot’s main features:
Get information about Telos accounts: display stats about CPU, NET, and RAM resources, total
balance, votes cast and inclusion in snapshots.
Monitor accounts and premium names: subscribe to real-time notifications and set a threshold to
filter out irrelevant Tx.
Check TLOS exchange rate in EOS and US dollar, or use the TLOS to USD converter.
Know current RAM price on Telos Mainnet in TLOS/KB
This is a demo application of Sensor DApp. The chart displays sensor data uploaded to the Telos
Blockchain from a light app running on a Raspberry Pi equipped with some external sensors. You can
adjust some parameters to choose different sensor data or time scale.
Goals: Faithful monitoring of parameters (temperature, humidity ...) for logistics
or other areas.
Solution: Real-time sensor registration application in blockchain.
Beneficiaries: Agrifood, pharmaceutical traceability, etc.
Registration and control of data related with the lifecycle of
vehicles.
In this project we have developed an application, CarTrustChain, which store relevant information
about the story of a vehicle in an Ethereum public blockchain. An example of the information secured
in a blockchain for each vehicle is the odometer reading at each time during its
servicing/maintenance cycle.
The aim is not only prevent the odometer fraud but also improve the air quality of cities.
Registering more valuable information of a vehicle, apart from its mileage, such as its correct
maintenance, will also benefit the air quality of cities. Because a faulty engine, may be caused by
skipping or not properly servicing the vehicle as recommended by its maker, could cause pollution and
damage the catalyser.
LiftsOnTheBlock
IoT implementations for the automated maintenance of machinery.
In this project we have developed a system based in a blockchain that registers most usual
incidences that can happen to an elevator, such as broken cabin light, elevator overload, doors not
closing, etc., as well as maintenance and repair activities. This way all stakeholders
(manufacturers, maintenance companies, building tenants, control authorities) will share relevant
information in a secure and trustworthy way, avoiding service conflicts (guarantee, insurance…) and
better complying with security regulations.
RockMyBlock
Blockchain-based ticketing platform.
In this project we have developed a blockchain-based ticketing platform for the management of
e-tickets that ensures security and flexibility while minimising the possibility of counterfeit
tickets. The whole ticket journey can be tracked by promoters from purchase to entry. Tickets are
verified simply by scanning the QR code that contains the ownership information. Once the show ends
artist and promoter are automatically paid based on how many total tickets were sold and the agreed
profit-sharing rules.
