Proof of Authority
During this phase, Polkadot will operate as a Proof of Authority (PoA) chain that is maintained by six validators belonging to Web3 Foundation. The chain will only allow users to claim DOT tokens or submit their intention to validate or nominate.
Explore what you can do in PoA
The launch of the PoA network opens up new options for developers, validators, nominators and enthusiasts.
Polkadot offers numerous resources to start learning and experimenting, ranging from the Substrate playground to in-depth documentation.

Validators who already hold DOTs can signal their intent to validate and stake on the network, nominators can signal intent to back specific validators.
What are DOTs? keyboard_arrow_rightDOTs are the native token of the Polkadot network, and are integral for key functions of the platform (detailed below).
What is the key difference between PoA and PoS? keyboard_arrow_rightPolkadot will be operated by Web3 Foundation nodes during PoA and will be a permissioned blockchain in this stage. When Polkadot transitions to Proof of Stake, the network will be a permissionless and decentralized chain operated by a set of community validators.
Why is Polkadot launching as PoA? keyboard_arrow_rightPolkadot will launch as PoA in order for DOT holders to claim their tokens, and to configure validator infrastructure. By launching in PoA mode, the network will build a decentralized validator set ready to take over on the switch to NPoS. The functionality of the network will be restricted to claiming DOT tokens and staking, and Web3 Foundation does not make any inflationary rewards during this period.
How long will Polkadot be in PoA? keyboard_arrow_rightThe benchmark to move into the next stage is a sufficient amount of validator intentions, which ensures a stable and secure network. The number of intentions can be as low as 50 but will probably be closer to 100, as it was with Kusama.
How will Polkadot move to NPoS? keyboard_arrow_rightWeb3 Foundation will use ‘Sudo’ - a superuser account with access to governance functions - to initiate the first validator election.
Can I transfer my DOTs? keyboard_arrow_rightNo, DOT transferability is not yet enabled in the PoA stage. However it is possible to claim DOTs if you bought them in an earlier DOT token sale. Go to claims.polkadot.network to start your claim.
When DOTs, kind sir? keyboard_arrow_rightSoon.
How can nominators signal intent to nominate? keyboard_arrow_rightNominators follow a similar process like validators to signal their intent. Read through the corresponding sections of the wiki.
Where can I ask additional questions? keyboard_arrow_right
How do we move forward?
Once the network is running smoothly and has a sufficient number of well staked validators, we will enable Nominated Proof of Stake with a Sudo call to change eras, and therefore perform the first validator election.See All Phases
