Validator Overview
dotOne Smart Chain relies on a system of validators operating under a Proof of Staked Authority (PoSA) consensus mechanism, enabling short block times and low transaction fees. Validators are the backbone of the network — they propose and validate blocks, confirm transactions, and ensure the protocol runs securely and efficiently.
What Is a Validator?
Validators are nodes responsible for producing blocks and securing the dotOne network. They participate in packaging transactions, creating and validating blocks, and maintaining ledger consistency — earning DOTO tokens as rewards in return.
A validator role is not purely technical. It is a long-term commitment to network reliability, uptime, and honest participation in consensus.
Validator Election & Consensus
dotOne conducts a daily election after 00:00 UTC to select the top active validators based on their staking rankings for block production. Among the elected set:
Cabinets — the validators with the highest staked amounts; more likely to be selected as consensus validators each epoch.
Candidates — the remaining active validators with a slightly lower probability of selection per epoch.
Each epoch, a subset of Cabinets and Candidates is selected to form the consensus validator set responsible for producing blocks in that round. Validators not elected into the active set must wait for the next election cycle.
If a validator is selected for block production but fails to participate, it will face slashing consequences.
Network Topology
Validators on dotOne are interconnected via a peer-to-peer (P2P) network, supporting both direct and indirect connections. As a validator operator, you can choose between two deployment modes:
Mode A — Standard (Ease of Use) Expose your validator's public IP directly to the P2P network. This mode offers high efficiency with fewer network hops. It is strongly recommended to disable HTTP access and protect your node's information to mitigate DDoS risks.
Mode B — Sentry Node (Enhanced Security) Conceal your validator behind one or more Sentry Nodes — full dotOne nodes that act as a protective layer between your validator and the public network. This mode shields your validator from DDoS attacks and other external threats, and is the recommended configuration for production validators.
Economics
Validator rewards come from two sources:
Transaction fees collected from blocks produced
Commission fees from delegators who stake DOTO to your validator
As an example, assuming a block reward of 100 DOTO and a validator with 20% self-bonded DOTO and a 20% commission rate:
Commission (to validator)
100 × 20%
20 DOTO
Remaining for delegators
100 − 20
80 DOTO
Validator's delegation share
80 × 20%
16 DOTO
Other delegators' share
80 × 80%
64 DOTO
Total validator reward
20 + 16
36 DOTO
Reward distribution is designed to encourage consistent performance, align validators with long-term network growth, and support decentralization over concentration.
You can track validator activity and reward history on the dotOne Explorer.
Risks & Slashing
Validators who act dishonestly, behave maliciously, or fail to maintain uptime may face slashing — a penalty that reduces their staked DOTO. The severity of the penalty depends on the nature of the violation:
Double Sign Running validator keys simultaneously on two or more machines constitutes a double-sign violation. Penalty: significant stake slash and an extended jail period preventing participation in consensus until manually unjailed.
Malicious Vote Running the same consensus and voting keys concurrently across multiple machines is treated as a malicious vote violation. Penalty: stake slash and jail time; an unjail transaction may be submitted after the jail period expires.
Downtime Missing a threshold number of blocks within a 24-hour window triggers an offline penalty. Continued downtime compounds the penalty and results in jail time, after which the validator must submit an unjail transaction to resume participation.
Low Self-Delegation Validators must maintain a minimum self-delegation of DOTO. Falling below this threshold results in a jail period until the minimum is restored.
Anyone can submit evidence of double-sign or malicious vote violations and receive a reward for doing so, contributing to network-wide accountability.
Validator Responsibilities
Operating a validator means accepting responsibility for network integrity. Validators are expected to:
Maintain secure and stable infrastructure
Follow protocol upgrade procedures promptly
Avoid any malicious or manipulative behavior
Participate transparently in consensus at all times
Network stability always takes priority.
