Bancor Protocol: Token Launch Report - Smith + Crown

Bancor Protocol: Token Launch Report

Bancor is a platform built on Ethereum that enables anyone to launch tokens backed by crypto-token reserves, such as ETH.

Update: Bancor raised 396,720 ETH within two hours, worth approximately $150 million at time of close.

It achieves this through the use of reserve-tokens, which provide liquidity through autonomous algorithmic price discovery, regardless of trade volume. — The Bancor Team

Bancor is a platform built on Ethereum that enables anyone to launch tokens, called “SmartTokens” in the protocol, backed by crypto-token reserves (initially ETH and others in the future). These SmartTokens can be freely traded and even used as the crypto-token reserves for issuing other tokens. The reserves are locked in a smart contract. Users will be able to specify the ratio of the SmartTokens total value to that of their reserve tokens, when launching configurable SmartTokens. The price at which the smart contract will issue new SmartTokens (if the reserve grows) or redeem SmartTokens (in exchange for reserve tokens) is a function of the following: the fixed ratio of SmartToken to reserve values, the existing supply of the SmartToken, and the quantity of funds held in a corresponding reserve. The smart contract underneath each SmartToken functions essentially like a distributed “central bank” with predictable monetary policy.

As a whole, this platform introduces three novel features to the industry.

  • Issue tokens backed by reserves with stabilized prices: it allows people to issue tokens that have a reserve, similar to how fiat currencies have central banks with foreign exchange reserves. It is one method of stabilizing the value of a currency, even though currencies are rarely backed one to one. Arbitrage should keep the price stable.
  • Marketplace of token changers: it can add a kind of liquidity to the token exchange market because the token reserves can be tapped when people want to buy or sell them using the SmartTokens that they back. Trading with reserves also incurs no fees beyond the Ethereum transaction fees (gas) needed to support the transaction.
  • Launch token baskets: it allows the easy launch of token or currency baskets, such as ETFs. This in turn could support the emergence of various exotic financial instruments as both the number and diversity of tokens grows.

The Bancor Protocol is based on John Maynard Keynes’ proposal after WWII at Bretton Woods to create a supranational currency that is beyond the scope of any one nation and has reserves based on the currencies of all participating nations.

Users interact with Bancor through their app and can launch tokens using chatbots. The Bancor team is using Bancor to run their token sale bounty program.

How does it work?

When someone wants to issue a Smart Token, they will set a Connector Weight (CW) that defines how many Smart Tokens are issued against the connected reserve balance. Countries that use a fractional reserve banking system will put into circulation much more currency than is technically redeemable: the theory is that only a fraction of people would redeem at any given time. A small reserve can support a larger supply of circulating monies, and the value of those circulating monies will reflect how much confidence the market has in both the reserve and the SmartToken relative to it.

Banks operate with a similar principle: using cash on hand, they can engage in transactions many times their value. In the US, the Federal Reserve requires that banks having a liability of over $115m have at least 10% as cash-on-hand. The array of debt instruments and financial relationships that exist in fiat-based economies is currently much more complex than that in the emerging crypto-industry, though the industry will likely see more tradeable debt tokens (such as Bitfinex’s BFX token) as time goes on.

The CW is more complex than just defining the number of SmartTokens relative to the number of reserve tokens: rather one can think of it as the value (measured against a third currency such as fiat) that the supply of SmartTokens should have relative to its reserve. The supply of SmartTokens and reserve tokens will adjust to reflect this, driven by the arbitrage the smart contract creates. The CW is between zero and one. If it is fixed to 1 upon the creation of a SmartToken then the reserve balance will be pegged to the total value of the SmartTokens, in a similar sense to how the USD was pegged to gold at 35$ an ounce until the early 70’s. A CW of 0.5 would imply a SmartTokens total value to be twice that of the connector balance.

Once the SmartToken is issued, its value relative to other currencies will float as foreign currencies do, but the CRR will determine how much of the reserve currency one SmartToken can be redeemed for and how many more SmartTokens can be issued by adding to the reserves. This establishes a target price (denominated in reserve currency per smart token) that the Bancor smart contract will honor in creation and redemption.

The CW equation is such that it becomes cheaper (priced as SmartToken per Reserve Token) to issue SmartTokens the more SmartTokens are in circulation. Given that both SmartTokens and Reserve Tokens have independent fiat prices (or relative to any other currency, though fiat is still the most stable) on the market, arbitrage should keep the supply of SmartTokens in line with the reserve requirements and aligning the relative fiat prices of the two.

If the reserve currency increases in value relative to third currency (such as fiat), the SmartToken will as well–and to a lesser extent, vice versa, though the effect will be small if the amount of reserve tokens held is small relative to the total supply.

SmartTokens themselves can also be used as the reserves of other SmartTokens, vastly increasing leverage in tokens.

What is the token being sold?

The Bancor Token will be the first token launched on the protocol, backed by the ETH in the crowdsale at a 20% Connector Weight (CW). The Bancor Token can be used by anyone to back additional SmartTokens. The Bancor Foundation will use some of the proceeds from the sale to launch more SmartTokens and support users in launching their own as well. If the Bancor Token is used as a reserve currency for another SmartToken, it will be accepted as part of the reserve.

The value of the Bancor Token will thus depend on both the value of ETH and the value of the SmartTokens that Bancor is used to back.

  • When the market price of ETH increases faster than Bancor’s, it becomes cheaper to get ETH through the smart contract until the supply of Bancor goes down (or the price of ETH goes down) until the price in the smart contract matches the relative prices in the market.
  • When the market price of Bancor’s increases faster than ETH’s, it becomes cheaper to get Bancor through the smart contract until the supply of Bancor goes up (or the price of ETH goes up) and the price in the smart contract matches the relative prices in the market.
  • Conversely, when the market price of a SmartToken with Bancor as a reserve goes up faster than Bancor’s, it becomes cheaper to get SmartTokens through the smart contract until the supply of SmartTokens goes up (or the price of Bancor goes up).
  • The effect of the SmartToken market price on that of the reserve token’s market price is relatively smaller than that of the reserve token’s on the SmartTokens’.

This also means that the value of the Bancor protocol token does not directly scale with the following:

  • Usage of the smart contracts for trading liquidity
  • Arbitrage profits collected by traders
  • Total users on the system (unless they use Bancor as a reserve token)

Bancor should retain a first-mover advantage that will privilege it as a reserve token of choice for future projects.

At time of writing, the terms have not been released yet.

What is the status of the project?

Update: There are now 77 tokens live on the Bancor network and weekly transaction volumes are approximately 40 million USD. Self-service token activation functionality is expected in Q3 of 2018. Followed by Token Creation functionality in Q1 of 2019. Looking forwards Bancor has ambitions to facilitate transactions between different blockchain architectures, collaboration with EOS aims to help facilitate this goal.

The Bancor app almost complete. There is currently a software bug bounty program for the smart contract on the mainnet itself. The Bancor app is actually running the software bug bounty program and the token sale bounty program, and bounty program participants will be paid from the Bancor protocol after it launches.

A full demo is available on the testnet. The entire project will be released to testnet before crowdsale. The mainnet release depends on debugging, audit results, feedback, and governance functionality release.
