Hardware Requirements
Hardware requirements for full validator nodes.
Validator Node
GSMA MNOs have the exclusive right to operate validator nodes and earn network fees. This section is provided to support Telcoin Association's authorized validator node operators. Telcoin (TEL) issuance is provided to Telcoin Network Validators to incentivize the growth of a secure, compliant, efficient financial platform.
Purpose of Node Specifications
Minimum hardware, connectivity, and hosting requirements are specified to maintain consistent and efficient performance across Telcoin Network. These ensure that all nodes meet a foundational standard, contributing positively to the overall network's health.
Pre-installation Review
Operators are required to submit detailed specifications of their intended node setup to Telcoin Network development team for approval before installation. Please contact our DevOps team at grant@telcoin.org with your proposed hardware specifications.

Please email support@telcoin.org to confirm hardware specifications before purchasing any equipment.
Observer Node
Observer nodes are permissionless participants in Telcoin Network that allow users to independently verify blockchain state without participating in consensus. These nodes synchronize with the network, maintain a copy of the blockchain, and can submit transactions directly to consensus validators. Unlike validator nodes, they do not validate blocks or participate in the consensus process.
CPU Requirements
x86 / x64 / ARM64 / AArch64
8 cores / 16 threads (higher clock speed over core count)
Memory
16-32 GB DDR4 ECC Registered DIMM, 2666MHz or faster
Storage
500GB - 2TB of TLC NVMe SSD (expandable)
Networking
Stable 24Mbps+ (download speed over upload)
Operating System
Supported OS: Linux LTS Releases Debian 11+Ubuntu 20.04+Red Hat Enterprise Linux (RHEL) 8 Kernel Version: Minimum 3.10+, MacOS Sequoia 15+
Observer nodes are ideal for:
Developers: Building applications on Telcoin Network who need reliable, direct access to blockchain data
Business integrators: Companies using Telcoin Network services who want independent verification of transactions and account states
Community members: Enthusiasts who want to support network resilience and independently verify network operations
Auditors and researchers: Organizations requiring transparent access to blockchain data without relying on third-party explorers
Application service providers: Entities offering services built on Telcoin Network who need direct transaction submission capabilities
Storage Recommendations: Why TLC over QLC
Understanding NVMe Drive Technology
When setting up nodes for Telcoin Network, storage selection significantly impacts node performance and longevity. We specifically recommend TLC (Triple-Level Cell) NVMe drives over QLC (Quad-Level Cell) options for several important reasons.
Performance Considerations
TLC drives offer higher sustained read/write speeds and better random I/O performance, which is critical for transaction processing and block validation. They maintain consistent performance during intensive blockchain operations and provide lower latency access to blockchain data. In contrast, QLC drives often suffer from performance degradation when their cache is saturated, causing inconsistent throughput that may lead to validation delays during high transaction volumes.
Durability and Lifespan
TLC drives typically support 1,000-3,000 P/E (program/erase) cycles, offering 3-5 times higher endurance rating than QLC alternatives. This superior sustained workload handling makes them better suited for continuous blockchain operations. QLC drives generally only support 100-1,000 cycles before cell degradation, and the continuous writes during validation can rapidly deteriorate QLC cells, leading to premature drive failure.
Blockchain-Specific Requirements
For Telcoin Network nodes, storage drives face continuous write operations when processing incoming transactions, validating new blocks, maintaining state databases, and recording blockchain history. While QLC drives offer upfront cost savings, the performance limitations and shorter lifespan ultimately make TLC drives the more cost-effective and reliable choice for maintaining node stability and network performance over time.
