 ## Conventions
 
-- Most libraries are internal libraries and have APIs which are completely unstable! There are few or no restrictions on backwards compatibility or rules about external dependencies. Exceptions are *libbitcoin_consensus* and *libbitcoin_kernel* which have external interfaces documented at [../shared-libraries.md](../shared-libraries.md).
+- Most libraries are internal libraries and have APIs which are completely unstable! There are few or no restrictions on backwards compatibility or rules about external dependencies. An exception is *libbitcoin_kernel*, which, at some future point, will have a documented external interface.
 
 - Generally each library should have a corresponding source directory and namespace. Source code organization is a work in progress, so it is true that some namespaces are applied inconsistently, and if you look at [`libbitcoin_*_SOURCES`](../../src/Makefile.am) lists you can see that many libraries pull in files from outside their source directory. But when working with libraries, it is good to follow a consistent pattern like:

-Shared Libraries
-================
-
-## bitcoinconsensus
-***This library is deprecated and will be removed in v28***
-
-The purpose of this library is to make the verification functionality that is critical to Bitcoin's consensus available to other applications, e.g. to language bindings.
-
-### API
-
-The interface is defined in the C header `bitcoinconsensus.h` located in `src/script/bitcoinconsensus.h`.
-
-#### Version
-
-`bitcoinconsensus_version` returns an `unsigned int` with the API version *(currently `2`)*.
-
-#### Script Validation
-
-`bitcoinconsensus_verify_script`, `bitcoinconsensus_verify_script_with_amount` and `bitcoinconsensus_verify_script_with_spent_outputs` return an `int` with the status of the verification. It will be `1` if the input script correctly spends the previous output `scriptPubKey`.
-
-##### Parameters
-###### bitcoinconsensus_verify_script
-- `const unsigned char *scriptPubKey` - The previous output script that encumbers spending.
-- `unsigned int scriptPubKeyLen` - The number of bytes for the `scriptPubKey`.
-- `const unsigned char *txTo` - The transaction with the input that is spending the previous output.
-- `unsigned int txToLen` - The number of bytes for the `txTo`.
-- `unsigned int nIn` - The index of the input in `txTo` that spends the `scriptPubKey`.
-- `unsigned int flags` - The script validation flags *(see below)*.
-- `bitcoinconsensus_error* err` - Will have the error/success code for the operation *(see below)*.
-
-###### bitcoinconsensus_verify_script_with_amount
-- `const unsigned char *scriptPubKey` - The previous output script that encumbers spending.
-- `unsigned int scriptPubKeyLen` - The number of bytes for the `scriptPubKey`.
-- `int64_t amount` - The amount spent in the input
-- `const unsigned char *txTo` - The transaction with the input that is spending the previous output.
-- `unsigned int txToLen` - The number of bytes for the `txTo`.
-- `unsigned int nIn` - The index of the input in `txTo` that spends the `scriptPubKey`.
-- `unsigned int flags` - The script validation flags *(see below)*.
-- `bitcoinconsensus_error* err` - Will have the error/success code for the operation *(see below)*.
-
-###### bitcoinconsensus_verify_script_with_spent_outputs
-- `const unsigned char *scriptPubKey` - The previous output script that encumbers spending.
-- `unsigned int scriptPubKeyLen` - The number of bytes for the `scriptPubKey`.
-- `int64_t amount` - The amount spent in the input
-- `const unsigned char *txTo` - The transaction with the input that is spending the previous output.
-- `unsigned int txToLen` - The number of bytes for the `txTo`.
-- `UTXO *spentOutputs` - Previous outputs spent in the transaction. `UTXO` is a struct composed by `const unsigned char *scriptPubKey`, `unsigned int scriptPubKeySize` (the number of bytes for the `scriptPubKey`) and `unsigned int value`.
-- `unsigned int spentOutputsLen` - The number of bytes for the `spentOutputs`.
-- `unsigned int nIn` - The index of the input in `txTo` that spends the `scriptPubKey`.
-- `unsigned int flags` - The script validation flags *(see below)*.
-- `bitcoinconsensus_error* err` - Will have the error/success code for the operation *(see below)*.
-
-##### Script Flags
-- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_NONE`
-- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_P2SH` - Evaluate P2SH ([BIP16](https://github.com/bitcoin/bips/blob/master/bip-0016.mediawiki)) subscripts
-- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_DERSIG` - Enforce strict DER ([BIP66](https://github.com/bitcoin/bips/blob/master/bip-0066.mediawiki)) compliance
-- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_NULLDUMMY` - Enforce NULLDUMMY ([BIP147](https://github.com/bitcoin/bips/blob/master/bip-0147.mediawiki))
-- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_CHECKLOCKTIMEVERIFY` - Enable CHECKLOCKTIMEVERIFY ([BIP65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki))
-- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_CHECKSEQUENCEVERIFY` - Enable CHECKSEQUENCEVERIFY ([BIP112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki))
-- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_WITNESS` - Enable WITNESS ([BIP141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki))
-- `bitcoinconsensus_SCRIPT_FLAGS_VERIFY_TAPROOT` - Enable TAPROOT ([BIP340](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki), [BIP341](https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki), [BIP342](https://github.com/bitcoin/bips/blob/master/bip-0342.mediawiki))
-
-##### Errors
-- `bitcoinconsensus_ERR_OK` - No errors with input parameters *(see the return value of `bitcoinconsensus_verify_script` for the verification status)*
-- `bitcoinconsensus_ERR_TX_INDEX` - An invalid index for `txTo`
-- `bitcoinconsensus_ERR_TX_SIZE_MISMATCH` - `txToLen` did not match with the size of `txTo`
-- `bitcoinconsensus_ERR_DESERIALIZE` - An error deserializing `txTo`
-- `bitcoinconsensus_ERR_AMOUNT_REQUIRED` - Input amount is required if WITNESS is used
-- `bitcoinconsensus_ERR_INVALID_FLAGS` - Script verification `flags` are invalid (i.e. not part of the libconsensus interface)
-- `bitcoinconsensus_ERR_SPENT_OUTPUTS_REQUIRED` - Spent outputs are required if TAPROOT is used
-- `bitcoinconsensus_ERR_SPENT_OUTPUTS_MISMATCH` - Spent outputs size doesn't match tx inputs size
