+Balances currently contains **RING** and **KTON**.
+
+**RING** is system token of Darwinia Network, the initial supply before Darwinia network mainnet release is 2 billion.
+
+**KTON** is the staking and governance credential of Darwinia Network, KTON can **only obtained by locking RING**, the initial supply is 0.
+
+At present, some **RING** and **KTON** exist in the Ethereum network and the Tron network in the form of **ERC-20** and **TRC-20**. These TOKENs will be transferred to the Darwinia main network by 1:1 cross-chain conversion after the Darwinia main online.

+# Kton
+
+To encourage users to make long term commitments and pledge, users can choose to lock RING for 3 - 36 months in the process of Staking, and the system will offer a KTON token as reward for users participating in Staking. During the committed pledge period, users can not unlock their RING. (Unless pay triple amounts of KTON as penalty)
+
+As a result, during RING staking process, user can choose to **lock RING for a period to receive KTON**. The initial supply amount of KTON should be zero, yet before Darwinia Mainnet launch, some users have already started locking their RING in Evolution Land, so there will be some KTON supply at the time of mainnet launch. The earliest design to obtain the KTON by locking the RING appears in the Gringotts of Evolution Land. The related introduction can refer to the Gringotts KTON model [5].
+
+KTON can be pledged to receive Staking power, so as to participate POS mining as well. User may Staking via pledge KTON, if user take back their staking KTON, then related POS mining is stopped, and it takes 14 days for unpledged KTON to arrive.
+
+## FAQ
+
+### What is Kton?
+
+**KTON** is the staking and governance credential of Darwinia Network, KTON can **only obtained by locking RING**, the initial supply is 0.
+
+### Where Kton from?
+
+Users can choose to lock RING for 3 - 36 months in the process of Staking, and the system will offer a KTON token as reward for users participating in Staking. 
+
+### When Kton spends?
+
+1. Transfer to other accounts.
+
+2. Burned by slashed.
+
+### What will happen after slashing?
+
+Slashed token goes to tresure.

+# Treasury Module
+
+The Treasury module provides a "pot" of funds that can be managed by stakeholders in the
+system and a structure for making spending proposals from this pot.
+
+- `treasury::Trait`
+- `Call`
+
+## Overview
+
+The Treasury Module itself provides the pot to store funds, and a means for stakeholders to
+propose, approve, and deny expenditures.  The chain will need to provide a method (e.g.
+inflation, fees) for collecting funds.
+
+By way of example, the Council could vote to fund the Treasury with a portion of the block
+reward and use the funds to pay developers.
+
+### Terminology
+
+- **Proposal:** A suggestion to allocate funds from the pot to a beneficiary.
+- **Beneficiary:** An account who will receive the funds from a proposal iff
+the proposal is approved.
+- **Deposit:** Funds that a proposer must lock when making a proposal. The
+deposit will be returned or slashed if the proposal is approved or rejected
+respectively.
+- **Pot:** Unspent funds accumulated by the treasury module.
+
+## Interface
+
+### Dispatchable Functions
+
+- `propose_spend` - Make a spending proposal and stake the required deposit.
+- `set_pot` - Set the spendable balance of funds.
+- `configure` - Configure the module's proposal requirements.
+- `reject_proposal` - Reject a proposal, slashing the deposit.
+- `approve_proposal` - Accept the proposal, returning the deposit.
+
+## GenesisConfig
+
+The Treasury module depends on the `GenesisConfig`.
