Lib Technologies is an American snowboard manufacturer known for its radically innovative approach to snowboard design.[1] Often referred to as Lib Tech, the company falls under the umbrella of parent company Mervin Manufacturing. Surf company Quiksilver bought Mervin in 1997.[2] As of 2013, Mervin was purchased by Altamont Capital Partners.[3]

Lib Tech produces snowboards, skateboards and now surf boards from their manufacturing base near Sequim, Washington[4] in the Pacific Northwest region of the United States.

History

Mike Olson built his first snowboard in 1977, and by 1984 had dropped out of Pacific Lutheran University, to begin making snowboards full-time.[5] Mervin Manufacturing's headquarters were set up in an "old racehorse barn," where Olson worked for two years, paying rent by mowing the lawn and cleaning the gutters for the barn's owner. Olson was quickly joined in his efforts by Pete Saari, and the two began churning out small orders for members of the nascent snowboard community.[6]

Technology

Magne-Traction

Gravitating away from the long, smoothly curving sidewall and edge of a traditional snowboard, Lib Tech's Magne-Traction technology employs a "serrated" edge consisting of seven bumps in the side wall.[7] According to Lib Tech's co-founder and VP of Marketing, Pete Saari:

"Magne-traction is 7 bumps or teeth along the length of your sidecut and edge each specifically sized and located to improve edge hold and focus control and power where you need it. The 3 largest most aggressive teeth are located between your feet adding control to the un-pressurable "dead zone" at and between your feet where your balance is centered. Smaller less aggressive teeth are located between your front foot and the contact area adding edge hold for turn initiation and control but keeping the tips and tails loose for catch-free freestyle."[8]

Since its debut, Magne-Traction has been generally well received by both reviewers and the general snowboard community, winning more than 15 Transworld Good Wood Awards and over 20 Future magazine awards.[7]

Banana Technology

The introduction of Lib Tech's Banana Technology marked yet another departure from orthodox snowboard design. Traditionally, snowboards are built with camber—the gentle arch formed in between the board's contact points when placed on a flat surface.[9] Camber geometry was first introduced for skis, which each have only one central area of pressure input (i.e., under the skier's boot). Snowboards, however, have two areas of pressure input (i.e., one under the front boot, and one under the back boot), leaving the rider unable to efficiently depress the center of the snowboard, an effect which Lib Tech's Pete Saari calls the "dead zone."[8]

Banana Technology does away with this "dead zone" by reversing the snowboard's camber between the rider's feet; rather than arcing upward, like traditionally cambered boards, those with Banana Technology arc downwards, allowing the board to rest on its center when placed on a flat surface. As Saari puts it, "Banana Technology focuses edge pressure between your feet, bringing the dead zone to life. It adds catch free tips and tails for jibs, rails, and forgiving landings. It adds pre-bent rocker between your feet for edge hold and carving, and it adds tip and tail float in powder."[8]

Banana Technology has been extremely well received by the snowboard community; in 2008, Banana Technology's inaugural year, Lib Tech experienced an 81% spike in sales.[5] Boards equipped with Banana Technology have garnered Lib Tech a slew of awards:

2007 Innovation of the Year, SIA Snowpress Innovation Awards (Skate Banana)[10]

Banana Technology (BTX), like Magne-Traction before it, begins with the premise that a snowboard is not a ski. Banana Technology replaces camber with rocker "Banana" between your feet. When you stand on your board, pressure is now applied inward to the edge area at the between your feet. As your weight presses out the rocker, tips and tails still make full contact for control and stability but edge pressure is reduced in tip and tail allowing them to float, climb and deflect like never before. The Banana Technology flex pattern is slightly stiffened at the tip and tail to increase pop and stability on big landings. Magne-Traction is incorporated into the Banana Technology to improve edgehold and put even more control underfoot at your balance point. The end result is a board that is loose and catch-free, presses boxes, rails and jibs extremely well with the preset rocker, maintains pop with a stiffened tip and tail, and turns easily on hardpack and ice when the built-in rocker is put on edge. The built-in rocker curve makes the board float naturally in powder and the firm nose and tail prevent the board from folding in chunky conditions.

Environmental sustainability

Lib Tech is known throughout the snowboard industry for their longtime commitment to environmental sustainability.[13] Mike Olson took the first steps towards sustainability early in the history of Lib Technologies; he replaced toxic ABS plastic with recyclable polyethylene in 1986, and introduced sustainable polymer topsheets and bamboo cores in 1995.[13]

Currently, Lib Tech even has its own environmental task force, dubbed the "environMENTAL division," which oversees the company's sustainability measures.[14] Not only does Lib Tech incorporate environmentally friendly materials into their snowboards (such as water-based graphics, non petroleum-based bio-plastic topsheets, Volatile organic compound resin, renewable wood cores, and basalt fiber rather than fiberglass), but the company has also designed their factory with the environment (and the health of their employees) in mind.[5][13][14][15] The factory's heating system runs on canola-based bio-diesel, which Lib-Tech makes available to employees and local farmers through a bio-diesel co-op program.[14] Wood sawdust is recycled as a soil additive, scrap wood is repackaged as kindling, and scrap plastics are reground and reused.[14] Water-cleansed grinding systems reduce airborne particulate levels, and the factory's air supply is constantly fresh due to a 2700% air-replacement ventilation system.[14]

Tyumen (/tjuːˈmɛn/ tew-MEN;[11][12] Russian: Тюмень, tr. Tyumen', IPA: [tʲʉˈmʲenʲ] (audio speaker iconlisten), Siberian Tatar: Тора[13]) is the administrative center and largest city and of Tyumen Oblast, Russia. It is situated just east of the Ural Mountains, along the Tura River, and has a population of over 750,000. Tyumen is among the largest cities of the Ural region and the Ural Federal District.

Tyumen was the first Russian settlement in Siberia. Founded in 1586 to support Russia's eastward expansion, the city has remained one of the most important industrial and economic centers east of the Ural Mountains. Located at the junction of several important trade routes and with easy access to navigable waterways, Tyumen rapidly developed from a small military settlement to a large commercial and industrial city. The central part of Old Tyumen retains many historic buildings from throughout the city's history.

Today, Tyumen is an important business center. It is the transport hub and industrial center of Tyumen Oblast – an oil-rich region bordering Kazakhstan – as well as the home of many companies active in Russia's oil and gas industry.

What is Secret Swap?

Secret Swap is a protocol for creating liquidity and trading SNIP-20 tokens on Secret Network. Leveraging secret contracts, Secret Swap protects users against malicious front-running and privacy threats, provides access to cross-chain liquidity, and reduces fees relative to Ethereum.

What is Front-running?

Front-running is an arbitrage strategy to make profit at someone else’s expense based on an information advantage. Front-running issue is not limited to DeFi, however the scale of the problem is amplified given the public nature of blockchains. Miners and arbitrage bots can see an order on the mempool before the order makes its way into the ledger and insert their orders with higher gas fees to be processed first. This means that the miner or the arbitrage bot can profit at the expense of a regular user. Furthermore, this arbitrage opportunity increases the gas fees of the underlying network, hurting users even more. Front-running problem on Ethereum DeFi costs users ~$1bn per year and millions of dollars in lost gas fees.

How does Secret Swap achieve front-running resistance?

SecretSwap is a protocol to swap secret contract based tokens (SNIP-20s) on Secret Network. Given the encrypted nature of SNIP-20s. Given the encrypted nature of secret contracts, inputs to a transaction/contract are encrypted while they are on the mempool and cannot be frontrun by any adversary. This ensure SecretSwap protects its users and their money from front-running attacks.

How do I use Secret Swap?

First, you’ll need a Keplr wallet and some $SCRT. Once completed, head over to SecretSwap to start using the protocol to provide liquidity or swap tokens. Since SecretSwap is built on Secret Network, each transaction and interaction costs $SCRT (the native coin of the network). This is called the “gas fee” and it’s paid to network validators to keep the network running.

How does Secret Swap work?

Secret Swap is an automated market maker (AMM) liquidity protocol. There is no orderbook, no centralized party, and no central facilitator of trade. Using Secret Contracts, the mempool of potential Secret Swap transactions are kept entirely encrypted - protecting users from front-running attacks and providing an increased level of privacy compared to traditional AMMs.

Each pool within Secret Swap is defined by a secret contract that includes a few functions to enable swapping tokens, adding liquidity and more. At its core each pool uses the function x*y=k to maintain a curve along which trades can happen.

The pools keep track of reserves (liquidity) and updates those reserves every single time someone trades. Because the reserves are automatically rebalanced, a Secret Swap pool can always be used to buy or sell a token without requiring a counterparty on the other side of your trade.

Note: Given the requirement to publicly update pool reserves to determine the price, an observer can see a consolidated view of changes (swaps, provide / remove liquidity) in a given block. As a result, if there’s a single transaction with the pool in a given block, it is not possible to have privacy on that transaction. With more transactions per pool in a given block, SecretSwap provides additional privacy to users.

For a more in depth description, check out how SecretSwap works in this blog post outlining the theory behind an AMM using secret contracts.

How are prices determined?

Prices are determined by the amount of each secret token in a pool. The secret contract maintains a constant using the following function: x*y=k.

In this case x = secret_token_0, y = secret_token_1, k = constant. For each trade, a certain amount of secret tokens are removed from the pool in exchange for adding an amount of the other secret token. To maintain k, the balances held by the secret contract are adjusted during the execution of the trade, therefore changing the price.

I saw a token was trading at X value, but when I traded on Secret Swap I got a much lower value?

There are 2 fees involved with a SecretSwap transaction: SecretSwap fees and Secret Network fees. SecretSwap fees are 0.3% of each swap deducted across the pairs. The fees are put back in the liquidity pool providing income for LPs of that pair. The fees can be changed in the future with decentralized governance enabled by $SEFI.

Secret Network requires $SCRT as gas to execute each transaction. Depending on the market price of $SCRT, transaction costs can increase or decrease.

Why does my transaction cost X?

Secret Network requires $SCRT as gas to execute each transaction. Depending on the market price of $SCRT transaction costs can increase or decrease.

SEFI Token

What is SEFI?

SEFI is the governance token for SecretSwap and the Secret DeFi ecosystem. Users of SecretSwap can earn SEFI to participate in shaping the future of the first front-running resistant, privacy-first open financial system. SEFI is a SNIP-20 or Secret Token, which means all SEFI transactions and contract interactions are private.

What is the total supply of SEFI?

Total supply of SEFI is set at 1,000,000,000. This amount is a non-inflationary fixed supply set at launch. 10% of the SEFI supply will be distributed at the genesis event to SecretSwap LPs during the soft-launch, SCRT stakers who secure Secret Network, users (depositors) of Secret Network-Ethereum bridge and UNI holders (above 400 UNI). The remaining 90% of the supply will be distributed over 4 years with a deflationary schedule. For more on SEFI tokenomics.

How can I claim my SEFI?

Users will be able to claim SEFI both on Secret Network with their Keplr Wallet and on Ethereum with their Metamask wallet. Users can claim their SEFI airdrop on the SecretSwap application. After you’ve claimed your SEFI, you can provide liquidity to sSCRT/SEFI pool or stake your SEFI and continue to earn SEFI after genesis.

Who else can earn SEFI after genesis?

SecretSwap LPs and SEFI stakers will begin earning SEFI after genesis. Traders on SecretSwap will also earn SEFI, though not immediately at genesis. Currently eligible pools for LP rewards are sSCRT/SEFI, sSCRT/sETH, sSCRT/sWBTC, sSCRT/sUSDT, sETH/sWBTC.

Will you be able to stake SEFI at launch?

Yes, you can use this link to stake SEFI and participate in SecretSwap governance. Staking SEFI provides impermanent loss free yield. SEFI staking is done through a secret contract, using the SecretSwap application.

What is the difference between an LP token and SEFI?

LP tokens are crypto-assets (secretTokens)mathematical proof that represents your ownership of a pool. When Alice provides provided assets to a pool, she receives LP tokens. Hand holding LP tokens means holding the claim to getting those assets back. This is in contrast to SEFI, which is the SecretSwap governance token used for managing application layer changes. Staking LP tokens allows you to earn SEFI.

Are rewards for SecretSwap LPs in SEFI or also in SCRT?

All SecretSwap rewards and governance are based on SEFI.

What is the difference between SEFI and SCRT when it comes to governance?

SEFI is used as an application layer governance token specifically for Secret Swap parameters, developer fund spending, and application related changes. This is in contrast to SCRT, which is the native governance token of the Secret Network protocol layer.

How is the price of SEFI determined at the beginning?

The price of SEFI will be determined by market forces of demand and supply.
