DevNet Structure & Entities

Complete overview of ASI:Chain DevNet architecture, components, and how they interact.

Network Overview

ASI:Chain DevNet is a development blockchain network designed for testing and experimentation. It consists of multiple interconnected components that work together to provide a complete blockchain ecosystem.

Current Configuration:

• Network Name: DevNet (Development Network)
• Status: Active
• Purpose: Testing, development, and learning
• Token Type: Test tokens (no real value)

Network Components

1. Bootstrap Node

Role: Network entry point and peer discovery

Function:

• Acts as the initial connection point for new nodes
• Maintains a list of active network participants
• Facilitates peer discovery
• Does not participate in consensus or validation

Technical Details:

• Host: 54.152.57.201
• Port Range: 40400-40405
• Connection String:

rnode://e5e6faf012f36a30176d459ddc0db81435f6f1dc@54.152.57.201?protocol=40400&discovery=40404

Key Characteristics:

• Single bootstrap node for the network
• Always-on availability
• No validator responsibilities
• Essential for network operation

2. Validator Nodes

Role: Consensus participants and block producers

Function:

• Validate transactions
• Propose new blocks
• Participate in consensus
• Sign blocks with validator keys
• Maintain network security

Technical Details:

• Current Count: 3 active validators
• Minimum Required: 3 validators for network operation
• Consensus: CBC Casper
• Block Time: ~20 seconds average

Validator Requirements:

• Valid public/private key pair
• Sufficient stake (on mainnet, not required on DevNet)
• Proper network configuration
• Open ports for communication
• Reliable uptime

External Validators: The network supports external validators joining:

• Anyone can become a validator
• Create wallet on wallet.dev.asichain.io
• Get test tokens from faucet
• Follow setup guide

3. Observer Node

Role: Read-only network participant

Function:

• Synchronizes with blockchain
• Provides read access to data
• Does not participate in consensus
• Does not sign or propose blocks
• Powers external services

Technical Details:

• Host: 54.152.57.201
• HTTP Port: 40453
• gRPC Port: 40451
• Port Range: 40450-40455

Use Cases:

• Blockchain explorers
• API services
• Data indexing
• Network monitoring
• Application backends

Public Access:

HTTP: http://54.152.57.201:40453
gRPC: 54.152.57.201:40451

• Simple interface

Function: Sends test ASI tokens to specified addresses

Network Architecture

Visual Diagram

Communication Flow

New Node Joining:

1. Node connects to Bootstrap Node
2. Bootstrap provides peer list
3. Node connects to Validators
4. Node synchronizes blockchain
5. Node participates (if validator) or observes

Transaction Flow:

1. User submits transaction to Validator
2. Validator validates and broadcasts
3. Other validators receive transaction
4. Consensus reached on new block
5. Block added to chain
6. Observer synchronizes new block
7. Explorer/Indexer update display

Data Query Flow:

1. User requests data via Wallet/Explorer
2. Request routed to Observer Node
3. Observer queries local blockchain copy
4. Response returned to user
5. Data displayed in interface

Port Allocation

Bootstrap Node

Service	Port	Purpose
Protocol	40400	Node communication
Public gRPC	40401	External API
Internal gRPC	40402	Internal API
HTTP API	40403	HTTP access
Discovery	40404	Peer discovery
Admin	40405	Administration

Validator Nodes

Validators use similar port ranges (404X0-404X5 pattern) but are not publicly exposed for security.

Observer Node

Service	Port	Purpose
Protocol	40450	Node communication
Public gRPC	40451	External API
Internal gRPC	40452	Internal API
