In order to mitigate this, the disclosure of the house entropy needs to be delayed beyond a reasonable reorg depth (notarization). It is recommended for production dice game with significant amounts of money to use such a delayed disclosure method.
Chapter 10 - lotto example
Chapter 10 - channels example
It might be hard to believe, but channels CC implements an instant payment mechanism that is secured by dPoW in a way that is backward compatible with the existing wallets, explorers, etc. and channels CC does not require both nodes to be online. Its usecases are all the usecases for Lightning Network, it is just more secure, less expensive and backward compatible! The one aspect which some might consider a downside (and others another benefit) is that all payments are onchain. This means it would increase blockchain size, but the idea is for channels CC to be used on blockchains with relatively lower value coins, so a txfee of 0.0001 is not anything significant.
Warning: very confusing blockchain reorganization issues described below. Will be confusing to most people
From a distance, the blockchain is a chain of blocks. One block after the next, each referencing all the prior blocks. Each block containing a group of transactions. Prior to getting into a block, the transactions are broadcast to the network and if it is valid, it enters the memory pool. Each miner then constructs a valid block from these memory pool transactions and when a transaction gets mined (confirmed), it is removed from the memory pool.
That is the simple version!
The reality is quite a bit more complex, but the critical aspect is that the blockchain can (and is) reorganized as part of the expected protocol. This can happen even when there is no 51% attack happening and it is important to understand this process in detail, so here goes.
What happens if two miners find a valid block at the same time? In this case the "same time" means within the time it takes for a block to propagate to the network. When a miner finds a new block, it is broadcast to the network and nodes update and start waiting for the next block. When there are two different (and valid) blocks propagating at the same time, some nodes update with one of the blocks and some the other, lets call it blockA and blockB. Now the nodes will know about both blockA and blockB, but some will consider blockA to be the chaintip and others will consider blockB to be the chaintip.
This is where it gets confusing. Which is the correct chaintip (latest block?). It turns out that both blockA and blockB are valid at this moment in time. So there are actuall two blockchains. We have what is called a small fork! Now dont worry, the protocol will help us converge to a single chain, but in order to do that, we need the next block.
Some miners will be mining from blockA and others from blockB. In most all cases, when the next block is found, it wont be at the "same time" again. So we will end up with a chain that is blockA+blockA2 or blockB+blockB2. Here comes the small reorg! Let's assuming blockA2 was found before blockB2, so that means all nodes that had blockB as the chaintip now see a longer chain blockA+blockA2, which trumps blockB. When that happens, it reorgs the chain so it is on blockA+blockA2. To do this properly, all the transactions that were in blockB are put back into the mempool and blockA is added, then blockA2.
Of course, when blockB2 arrives, the nodes see it but blockB+blockB2 is the same length as blockA+blockA2, so no reorg happens. Since we postulated that blockAs arrived "before" blockB2, that means all nodes are on the same chaintip, including all the miners and the next block found would be blockA3, without any complications.
Believe it or not, this sort of thing is happening all the time, one all blockchains. The chaintip is a volatile thing and that is why more than one confirmation is needed to avoid the small reorgs invalidating blockhash. However, it is possible for more than just the blockhash to change. When the reorg happens, all the transactions in the block are put back into the mempool and then the new blocks are processed in order. So what happens if one of the inputs to a transaction that happened in blockB, gets spent in blockA2? Based on random utxo allocation by wallets this is not impossible if an address has a lot of activity, but if it is part of a 51% attack, then this remote chance of an utxo being spent becomes a certainity! In fact, that is what a 51% attack is.
The attack can go much deeper than just one block. For chains that use the longest chain rule, it can go quite deep indeed. So as all the reorged transactions are put back into the mempool, we feel good that it will get confirmed again. Unfortunately, there is no enforcement of a miner needing to mine any specific transaction in the mempool. And the 51% attacker is intent on mining the transaction that spends an already spent utxo in the reorganized chain. it is called a double spend, but in the reorganized chain, it is spent only once. So it is a bit of a misnomer.
The important thing to understand is that if any transaction has inputs that are signed by a node, it is possible when the chain reorganizes for that transaction to become invalid. This is why dPoW is important as it doesnt strictly use the longest chain rule, but rather the longest notarized chain rule. Once a block is notarized, then it will refuse to reorganize that block (or any block before). So the risk is still there, but only until a notarization. Please see more detailed information about dPoW <here>.
Given the above, if you are wondering how can it be possible to have a mempool payment be secured by dPoW. Since it is explained how the reorgs can make valid transactions disappear, it seems unlikely any such solution is possible. However, the CC is very powerful and it can make unlikely things possible.
The following describes how.
We know that any payment that is utxo based can be invalidated via 51% attack, or even an unlikely but not impossible random utxo allocation from a busy wallet. Which means the payment cant be via a utxo. Since the CC system is utxo based, you might think that it means CC cant solve this. However, CC is very powerful and can implement payments that are not utxo based. But before this non-utxo payment method is explained, first we need to solve the mechanics of payment.
At a high level, we want to lock funds into a channel, have this lock notarized so it cant be reorganized. Then payments can unlock funds. Additionally, if we are restricting the payment to just one destination, we also need a way for the sender to reclaim the unused funds. So there needs a way for a close channel notification, which when notarized allows the sender to reclaim all funds. After the channel close is notarized, then the only action possible should be a reclaim of sender funds.
We need to assume that any payment, channel close, reclaim can be reorganized until it is notarized so great care needs to be made that a payment that is made will always be valid. With some allowances for blocks after a channelclose is notarized, we can protect the payments using the logic of "stop accepting payments after a channelclose is seen". It might be that a full notarization of wait time after the channelclose is notarized is needed to provide sufficient time for all the payments to be reprocessed.
Now we can finally describe the requirements for the CC. The locked funds need to be able to be spent by either the sender or receiver, the former only after sufficient time after a channelclose and the latter only after a payment is seen (not just confirmed, but just seeing it should be enough). The protection from reorgs is that the payment itself reveals a secret that is needed for the payment and only the secret would be needed, so it wont matter what utxo is used. To lock funds into a CC address that can handle this we need a 1of2 CC address, which can accept a signature from either of two pubkeys. The additional CC constraints would be enforced to make sure payments are made until the channel is closed.
A hashchain has the nice property of being able to encode a lot of secrets with a single hash. You can hash the hash, over and over and the final hash is the public value. By revealing the next to last hash, it can be verified that it hashes to the final hash. There is a restriction that a hashchain needs to be of reasonable maximum depth, say 1000. That means each iteration of the hashchain that is revealed is worth 1/1000th the total channelfunds. In fact, if the 500th hash value is revealed, half the channelfunds are released. this allows 1/1000th resolution that can be released with a single hash value.
Now we can make the payment based on the hashvalue revealed at a specified depth before the prior released hashchain value. Both the sender and receiver can make a payment to the destination by attaching a hashchain secret. This means even if the sender's payment is reorganized, if the destination has the revealed secret, a replacement payment can be made that is valid. If the destination account isnt monitoring the blockchain, then it wont see the revealed secret, but in this case there shouldnt be value released for the payments that are reorganized. So it would be a case of no harm, no foul. In any event, all the payments end up verifiable on the blockchain to provide verifiability.
Payments at the speed of the mempool, protected by dPoW!

Chapter 11 - oracles example
Oracles CC is an example where it ended up being simpler than I first expected, but at the same time a lot more powerful. It is one of the smaller CC, but it enables creation of an arbitrary number of data markets, in a performant way.

I hope this document has helped you understand what a Komodo utxo based CC contract is and how it is different from the other smart contracts. If you are now able to dive into the cc directory and start making your own CC contract, then I am very happy!
gateways CC
gateways CC is the first CC that combines multiple CC into a single one. In order to achieve its goals, both the assets CC and the oracles CC is used, in addition to a dapp that issues regular transactions. This general approach can be used to solve quite a few different use cases, so it is important to understand how a multi-CC solution is put together. There are some tricky issues that only arise when using more than one CC at a time.
Before the implementation details, first lets understand what the gateways CC does. At a high level it is similar to the old multigateway (from NXT AE 2014), but with improvements. The basic idea is to tokenize other crypto coins (like BTC) and then use the assets CC to transact/swap against the tokenized crypto. By enforcing a 1:1 peg between a specific token and BTC and an automated deposit/withdraw mechanism, it is possible to transact in the virtual BTC without the delay or expensive txfees. Then anybody that ends up having any of the BTC token would be able to withdraw actual BTC by redeeming the token.
BTC -> deposit to special address -> receive token that represents BTC onchain
do onchain transactions with the BTC token
anybody who obtains the BTC token can redeem the token and get actual BTC in the withdraw address
By bringing the operations onchain, it avoids the need for crosschain complications for each trade. The crosschain does still have to happen on the deposit and withdraw, but that is all. There is just one aspect that makes it not fully decentralized, which is the reliance on MofN multisig. However, with N trusted community members and a reasonable M value, it is not expected to be a big barrier. Since all operations are automated, the only trust needed is that M of the N multisig signers are running their nodes with the gateways dapp active and also that M of them wont collude to steal the funds locked in the multisig. In three years of operations, the MGW multigateway didnt have any incident of multisig signer misbehavior and it was only 2of3 multisig.
How can the gatewaysCC work? First, it needs a dedicated token that can be used to represent the external crypto coin. In order to avoid any issues with misplaced tokens, it is simplest to require that 100% of all the tokens are all locked in the gatewaysCC address. We want to make it so that the only way the tokens can be released from the locked address is when a verified deposit is made. So, we also need a deposit address, which means there needs to be a set of pubkeys that control the deposit address. It turns out, we also need to post merkleroot data from the external coin so that the information is onchain to be able to validate the external deposit. Since we are already trusting the deposit address signers to safekeep the external coins via MofN multisig, trusting them to post the merkleroots doesnt increase the trust footprint needed.
Now we have all the ingredients needed, a dedicated token, a set of multisig pubkeys and an oracle for merkleroots.
gatewaysbind tokenid oracletxid coin tokensupply M N pubkey(s)
With a gatewaysbind, a new gateway is defined. the pubkeys are for the custodians of the multisig funds and they also need to be posting merkleroots to the chain, so the oracle needs to be setup and funded and each of the signers needs to run the oraclefeed dapp. That posts each new merkleroot via oraclesdata and also responds to withdraw requests.
The MofN pubkeys generates a deposit address and when funds are sent to that address along with a small amount to the claim address. With the txid from this external coin, along with the txproof and the rawtransaction, all is submitted with a gatewaysdeposit. This adds a special baton output which is a gateways CC output to invoke gateways validation and also prevents double claims by using the unspent status of the baton.
gatewaysdeposit bindtxid height coin cointxid claimvout deposithex proof destpub amount
gatewaysclaim bindtxid coin deposittxid destpub amount
Once the gatewaysdeposit is validated, it can be claimed and now the token is sent to the claim address. A 1:1 pegging of the external crypto to the token is established. And as long as one of the deposit address signers is running the oraclefeed, then the deposit/claim process is fully automatic and under the control of the depositor. Nothing needs to be signed by any other party! Also by using the utxo from the deposittxid, double claims are prevented.
On the withdraw side, the tokens are sent back to the address where the tokens are locked and this needs to create a redemption right that can only be used once.
gatewayswithdraw bindtxid coin withdrawpub amount
And with a bit more magic in the oraclefeed, this is achieved. To be continued...

Implementation Issues:
When thinking about validation, it is clear that we cant use EVAL_ASSETS for the locked coins as there wont be any enforcement of the gateways locking. This means we need a way to transfer assets into gateways outputs and back. It seems a tokenconvert rpc will be needed and hopefully that will be enough to make it all work properly.
Care must be taken so that tokens are not lost and can be converted back.
This changes the usage to require tokenconvert before doing the bind and also tokenconvert before doing a withdraw. EVAL_GATEWAYS has evalcode of 241
The gatewaysclaim automatically converts the deposit amount of tokens back to EVAL_ASSETS.

/*
The idea of MofN CC is to allow non-interactive multisig, preferably in a cross chain compatible way, ie. for actual bitcoin multisig.
full redeemscript in an initial tx with opreturn
ability to post partial signatures and construct a full transaction from M such partial signatures
a new transaction would refer to the initialtx and other partial would refer to both
There is no need for a CC contract to use it for normal multisig as normal multisig transactions are already supported.
In order to take advantage of CC powers, we can create a more powerful multisig using shamir's secret MofN (up to 255) algo to allow spends. Using the same non-interactive partial signing is possible. also, in addition to spending, data payload can have additional data that is also revealed when the funds are spent.
rpc calls needed:
1) create msig address (normal or shamir)
2) post payment with partial sig
3) add partial sig to 2)
4) combine and submit M partial sigs
The idea of Heir CC is to allow crypto inheritance.
A special 1of2 CC address is created that is freely spendable by the creator. The heir is only allowed to spend after the specified amount of idle blocks. The idea is that if the address doesnt spend any funds for a year (or whatever amount set), then it is time to allow the heir to spend. The design requires the heir to spend all the funds at once

Funds work like with dice, ie. there is a Prices plan that traders bet against.
PricesOpen -> oracletxid start with 'L' price, leverage, amount
funds are locked into global CC address
PricesFunding oracletxid, margin, priceaveraging, maxleverage, funding, longtoken, shorttoken, N [pubkeys]
PricesBet -> oracletxid start with 'L', leverage, funding, direction
funds are locked into global CC address
it can be closed at anytime by the trader for cash settlement
the house account can close it if rekt
Implementation Notes:
In order to eliminate the need for worrying about sybil attacks, each prices plan would be able to specific pubkey(s?) for whitelisted publishers. It would be possible to have a non-whitelisted plan that would use 50% correlation between publishers.
delta neutral balancing of risk exposure
delta neutral balancing of riskexposure: fabs(long exposure - short exposure)
bet +B at leverage L
absval(sum(+BLi) - sum(-Bli))
validate: update riskexposure and it needs to be <= funds
PricesProfits: limit withdraw to funds in excess of riskexposure
PricesFinish: payout (if winning) and update riskexposure
need long/short exposure assets
funding -> 1of2 CC global CC address and dealer address, exposure tokens to global 1of2 assets CC address
pricebet -> user funds and exposure token to 1of2 address.
